    OBJECTIVE: To evaluate the risks imposed by tobacco smoking, in particular, bidi smoking, in the development of lung cancer. METHODS: Two hundred eighty-four histologically confirmed patients of bronchogenic carcinoma and 852 controls matched for age, sex, and socioeconomic status were interviewed according to a predesigned questionnaire. Effects of individual variables defining the various aspects of tobacco smoking, in particular, bidi smoking, were assessed using logistic regression models. RESULTS: 81.3% cases of bronchogenic carcinoma were ever smokers as compared with 42.2% among controls. The odd ratios for ever smoking, bidi smoking, and cigarette smoking were 5.9 (confidence interval [CI] 4.3, 8.4), 6.1 (CI 4.3, 8.7), and 5.3 (CI 2.7, 10.4), respectively. CONCLUSION: Bidi smoking poses a very high risk for lung cancer even more than that of cigarette smoking. PMID:20981185

    Orbital metastasis in systemic cancer is known to occur and occurs in up to 7% of all systemic cancers. Orbital features typically present after the diagnosis of the primary tumor. In about 20% of cases, there is no known primary cancer at the time of presentation with orbital metastatic disease. Here we report a case of a 60-year-old male smoker, in whom proptosis, due to metastasis in greater wing of left sphenoid bone secondary to bronchogenic carcinoma, was the initial symptom. We could not find in literature metastasis to greater wing of sphenoid bone due to small cell carcinoma of lung.

    Fibrosing mediastinitis is a rare but benign disorder characterized by an excessive fibrotic reaction in the mediastinum which can result in compromise of airways, great vessels, and other mediastinal structures. In this paper we presented a patient with fibrosing mediastinitis mimicking bronchogenic carcinoma. The patient was a 32-year-old diabetic male admitting with cough and hemoptysis. There was a right hilar mass and multiple mediastinal conglomerated lymph nodes on chest computed tomography. Positron emission tomography with computed tomography (PET/CT) scan demonstrated increased fluorodeoxyglucose (FDG) uptake at the right hilar mass lesion and mediastinal lymph nodes. Fiberoptic bronchoscopy showed mucosal distortion of right upper lobe. Pathologic examination of the mucosal biopsy revealed inflammation. Endobronchial ultrasound guided transbronchial needle and cervical mediastinoscopic lymph node biopsies were undiagnostic. Diagnostic thoracotomy confirmed the diagnosis fibrosing mediastinitis. Administration of six months of systemic corticosteroid and antituberculous therapy was not beneficial. In conclusion, despite being a rare clinical entity, fibrosing mediastinitis should be kept in mind in the differential diagnosis of mediastinal mass lesions of unknown etiology. The diagnosis is exceptionally difficult in the presence of atypical radiological findings. The treatment is particularly challenging without any proven effective therapy. PMID:23372962

    Eighty patients with carcinoma of the lung have been treated at the Nova Scotia Sanatorium since 1940; in 15, coexisting active pulmonary tuberculosis was present. No characteristic clinical or roentgenological findings indicated that the tuberculous individual also had lung cancer. In four cases cancer was not diagnosed until the lung was examined by the pathologist. In the others a considerable interval elapsed before carcinoma was suspected. Only four patients with known cancer were considered suitable for thoracotomy. In three, an attempt at curative resection was made. One survived over seven years before accidental death; one is alive less than one year after operation; the third died as a result of the surgery. Bronchogenic carcinoma should be suspected in every tuberculous patient over the age of 50; diagnostic investigations should include bronchoscopy and cytological studies of bronchial secretion and sputum. Suspicion of carcinoma in any such patient constitutes an indication for early resection of the tuberculous disease. PMID:5843871

    Computed tomography has become an important diagnostic modality in the preoperative staging of patients with bronchogenic carcinoma. The adrenal glands represent one of the most frequent sites of metastasis. Therefore, an isolated adrenal mass discovered on preoperative thoracoabdominal CT poses a diagnostic problem. Three hundred thirty patients with histologically proved nonsmall-cell bronchogenic carcinoma were evaluated. Thirty-two had adrenal masses without further evidence of disease in the abdomen, Eight of these 32 masses were metastases, 17 were proved adenomas, and 7 did not undergo biopsy. Thus an isolated adrenal mass is more likely benign than metastatic, and biopsy is advocated prior to withholding potentially curative surgery.

    A total of 114 patients with bronchogenic small cell anaplastic carcinoma and staged as having regional disease all underwent combination chemotherapy consisting of CCNU, cyclophosphamide, and methotrexate. They were randomized to receive either radiotherapy to the primary tumor and regional lymph nodes (4000 rad) or extensive radiotherapy, which included the brain, adrenals, and upper retroperitoneal lymph nodes. Fifteen patients were free of disease after 18 months of chemotherapy and the treatment was discontinued. Only 3 patients subsequently relapsed. No difference was observed between the two groups of patients in median survival time, response rate, duration of response, or relapse pattern, including the frequency of brain metastasis.

    All cases of bronchogenic carcinoma treated with curative intent over an eight-year period were reviewed. Most were treated with 12 X 400 rad in 32 days using 60Co, a schedule designed to optimize the radiation-sensitizing properties of hyperbaric oxygen. While O2 gave no obvious benefit, overall four-year survival was 10.6% and that of patients with good prognostic indicators was 18%. No radiation myelitis was observed. This protocol delivers an adequate tumor dose and appears to be tolerated well by most patients.

    Gastric bronchogenic cysts are rare lesions, first described in 1956, with only 34 cases reported in the literature to date. The present study described a case of bronchogenic cyst of the stomach in a 17-year-old female who presented with periodic epigastric pain. In addition, the study analyzed the existing literature on these lesions. Gastric bronchogenic cysts are more common in females (female:male ratio, 21:14) and the median age of their development is 43 years. In total, 48.57% of the 34 previously reported cases were identified incidentally, and the remainder presented mainly with epigastric pain. Cyst sizes varied between 1.7 and 15 cm. In 3 cases, preoperative diagnosis was performed using needle biopsy, whereas several studies were initially misdiagnosed as stromal tumors. In 85% of the cases (31/35), cyst resection was performed, with laparoscopy used in 4 of the cases. The findings of the present study and literature review suggested that bronchogenic cysts of the stomach are rare, and surgical resection is warranted to treat symptoms and prevent malignant transformation.

    One hundred ten patients with proved bronchogenic carcinoma who were undergoing computed tomography (CT) of the thorax also underwent CT of the adrenals to determine the value of routine preoperative assessement of this gland. Sixteen adrenal masses were found in 11 patients. In five patients the adrenals were the only site of metastasis. CT of the adrenals should be performed routinely when the thorax is examined pre-operatively in patients with non-oat-cell bronchogenic carcinoma to improve patient selection for thoractomy.

    The Mayo Lung Project (MLP) is a screening program designed to detect bronchogenic carcinoma at a curable stage. Screening tests include chest roentgenograms, three-day "pooled" sputum cytology studies, and lung-health questionnaires. These are being applied every four months to a study population of outpatients who have a high probability of developing lung cancer. Initial patient acceptance of the screening program has been excellent. Small asymptomatic lung cancers have been detected both roentgenographically and cytologically. The two procedures have complemented each other with little overlap. Chest roentgenography has proved most useful in diagnosing peripherally situated cancers, whereas sputum cytology studies have been most effective in identifying early squamous cancer involving major airways. At present, more cancers have been detected roentgenographically than cytologically, but the cytologically detected cases appear to have a better prognosis. Roentgenographically occult cancers have been localized with regularity, although the localization process is complicated. Theoretically, vigorous application of radiologic and cytologic screening, combined with optimum use of localizing procedures and treatment, could increase the five-year survival rate among lung cancer patients to nearly 50 percent. However, the actual survivorship attained will ultimately be determined by currently imponderable factors such as patient acceptance of longterm screening, frequency of multicentric respiratory cancers, and incidence of noncancerous smoking-related diseases, especially chronic obstructive pulmonary disease and ischemic heart disease.

    We report a 54-year-old woman who presented with a well-defined, homogeneous, and non-enhancing mass in the retrobronchial region of the bronchus intermedius. The patient underwent endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for histological confirmation. Serous fluid was aspirated by EBUS-TBNA. Cytological examination identified an acellular smear with negative microbiological cultures. The patient was finally diagnosed with bronchogenic cysts by chest computed tomography (CT) and EBUS-TBNA findings. However, 1 week after EBUS-TBNA, the patient developed bronchogenic cyst rupture and pneumonia. Empirical antibiotics were administered, and pneumonia from the bronchogenic cyst rupture had resolved on follow-up chest CT. To our knowledge, this is the first reported case of pneumonia from bronchogenic cyst rupture after EBUS-TBNA. PMID:23678359

    Preoperative chest computed tomographic (CT) scans in 84 patients with biopsy-proven non-small cell bronchogenic carcinoma were reviewed. At least one adrenal gland was visualized in 70 of these. Evidence of a solid adrenal mass was present in 18 (14.5%) glands in 15 (21.4%) patients. Percutaneous needle aspiration under CT guidance confirmed metastatic malignancy in the four patients who were biopsied. Because the documented presence of adrenal metastases in non-small cell lung cancer makes surgical resection or local irradiation inappropriate, it is recommended that both adrenal glands in their entirety be specifically included whenever a staging chest CT examination is performed in patients with such tumors. Percutaneous needle biopsy for pathologic confirmation of the nature of solid adrenal masses discovered in this process is also useful.

    Bronchogenic cyst is a rare developmental lesion. It is usually asymptomatic and most frequently located in the middle mediastinum and lung parenchyma. It can cause symptoms only when infected or pressing on neighboring structures. The MRI findings in a 34-year-old woman with an 8 months history of back pain were evaluated and revealed a cystic lesion in the left paravertebral area. The histopathologic evaluation of the material aspirated with CT guidance was reported to be bronchogenic cyst. A simultaneous alcohol ablation was accomplished. After the procedure the patient's pain disappeared and the follow-up MRI scan 1 year later revealed no relapse. Paravertebrally located bronchogenic cysts are very rare and only 3 cases were found to be reported in the medical literature prior to this one. While aspiration alone is sufficient for diagnosis, it is insufficient to treat the lesion and prevent the recurrences. This paper reports a paravertebral bronchogenic cyst which was symptomatic despite of its small size. CT-guided aspiration was accomplished and simultaneous alcohol ablation was carried out to prevent recurrences.

    We determined the frequency of expression of the major histocompatibility complex antigens HLA-A,B,C in tumor cells from 207 primary tumor lesions of breast and bronchogenic carcinomas, to see if the expression of theses antigens was linked with several clinicopathological parameters associated with tumor aggressivity, such as abnormal cellular DNA content. We compared tumor tissues with nonneoplastic tissues and tissues from 15 benign breast lesions. HLA class I expressor and nonexpressor tumor cells were determined by using immunohistochemical stains (PAP and APAAP methods) and antibodies against these antigens. Reduction of HLA class I antigen was detected in 65 tumors (31.7%) and was significantly associated with poor tumor differentiation and abnormal cellular DNA content (p < 0.001). These characteristics might define a group of aggressive tumors in which the decrease of HLA class I antigens would enable tumor cells to avoid eliciting host immune responses. On the other hand, the altered regulatory mechanisms, of tumors with abnormal cellular DNA content, might modulate the expression of HLA class I molecules.

    Congenital pericardial defects are a rare anomaly, found during autopsy and cardiothoracic surgery. We describe a case of a 69-year-old female, with a right-sided congenital pericardial defect associated with a giant bronchogenic cyst (BC) found during surgery. The cyst was resected and the patient developed arrhythmia following surgery. A review of the literature in Japan was performed, focusing on congenital anomalies associated with pericardial defects and its pathogenesis. We paid particular attention to complications following thoracic surgery in patients with pericardial defects and indications of pericardial reconstruction in such patients. PMID:27621900

    Bronchogenic cysts (BCs) are congenital malformations that originate from remnants of the primitive foregut. Intraspinal BCs, especially those of the conus medullaris are rare with only one case reported until now. To date, a bronchogenic cyst with spinal cord tethering has not been previously reported. We reviewed the clinical course of a 44-year-old woman, who presented with low back pain and leg weaknesss as well as sphincter disturbance. Magnetic resonance imaging showed an intradural oval mass located at the conus medullaris. A tethered cord was also observed, as well as a dermal sinus tract. The mass was totally removed after an L3-L4 laminectomy without detethering during operation. Pathologic examination confirmed the diagnosis of bronchogenic cyst. By six months after treatment, the patient had experienced nearly complete recovery. The review of literature indicated that detethering was performed in most reported cases of neurenteric cysts with spinal cord tethering, and one of six patients was diagnosed with a postoperative recurrence. The co-existence of bronchogenic cyst and a tethered spinal cord would imply associated developmental errors in embryogenesis. It is worth noting that whether detethering is necessary after the cyst removal. PMID:26097578

    Asbestos-associated malignancies are one of the major industrial hazards of recent decades and will continue to be so until beyond the end of the century. It has been estimated that, in the United States alone, there will be 131,200 cancer deaths as a result of asbestos exposure. At present the early lesions are detected radiologically, by which time intervention is no longer effective. The aim of this study was to test the value of a battery of serum biomarkers in the early detection of malignancy and in distinguishing between the early stages of mesothelioma and bronchogenic carcinoma. Many of the biomarkers had no discriminating value but on the basis of four such markers (namely TPA, CEA, HA and ferritin) it has been possible to distinguish between the late stages of the two malignancies and asbestosis. The results are discussed in terms of their possible application to the detection of early pre-malignant lesions in a screened population of asbestos-exposed persons, with the aim of attempting to prevent cancer death in such early detected cases.

    An in situ hybridization technique was applied to detect expression of keratin mRNAs in xenotransplanted human tracheobronchial epithelium and lung carcinomas. Tissues from eight tracheas repopulated with cells from five different noncancerous donors and 15 squamous cell carcinomas were used. Using a K6 (56 kd) human keratin cDNA (KA-1) and a K14 (50 kd) cDNA (KB-2) as probes, radiolabeled by nick-translation with 3H-dATP/TTP, the specificity and significant differences in the levels of silver grains on various epithelial lesions in formalin-fixed, paraffin-embedded tissue sections were demonstrated. In situ hybridization with either KA-1 or KB-2 probe showed similar localization of silver grains in all histologic types in consecutive tissue sections. In xenotransplanted tracheobronchial epithelia, very few grains were seen over cells of simple, pseudostratified, or stratified epithelia two to three cell layers thick. Nonkeratinizing stratified hyperplastic epithelia of more than three cell layers showed uniform localization of numerous grains throughout the lesions. In contrast, epidermoid metaplasias exhibited a dense and localized pattern of grains on the basal and parabasal cell layers with a decrease in grain density toward the surface layers. Carcinoma cells from bronchogenic squamous cell carcinomas showed a higher density and more uniform localization of grains. Well-differentiated carcinoma cells contained more keratin mRNAs than moderately to poorly differentiated carcinoma cells. This evidence obtained with the KA-1 and KB-2 probes demonstrates the different localization patterns of keratin mRNAs in different epithelial lesions. In addition, the levels of mRNA expressed show a positive correlation with the degree of squamous differentiation. It was of particular interest that an ordered program of keratin mRNA expression proportional to the level of cellular differentiation was observed in epidermoid metaplasias. Both of these probes serve as

    Combined positron emission tomography/computed tomography (PET/CT) using the glucose analogue 2-[18F]-fluoro-2-deoxy-D-glucose (FDG) has become the standard of care in oncological patients. However, due to the non-specific nature of FDG uptake, there are many physiological variants and benign pathological entities that also demonstrate augmented glucose metabolism, such as inflammatory and infective processes. Undiagnosed and retained foreign bodies (occult foreign bodies) in the lung can induce inflammatory reaction consisting of polymorphonuclear neutrophils, macrophages, and granulation tissue resulting in intense FDG uptake because of high metabolic activity and cell turnover. Here, we present a case of an occult foreign body imitating a tumor on PET/CT.  PMID:28265526

    Abstract Subcutaneous bronchogenic cysts have been described rarely, particularly among adolescents. Only a few reports have described the ultrasonographic features of bronchogenic cysts, characterizing them as nonspecific cystic masses with or without internal echogenic foci or debris. Therefore, it is hard to differentiate subcutaneous bronchogenic cysts from other subcutaneous cystic tumors ultrasonographically. We report a case of presternal subcutaneous bronchogenic cyst in an 18-year-old man with unusual ultrasonographic findings. Ultrasonography revealed a small, oval, cystic mass containing a well-circumscribed, heterogeneously hypoechoic, egg-shaped lesion in the dependent portion of the mass within the subcutaneous fat layer overlying the sternum. Surgical excision was performed, and the cystic mass was diagnosed as a bronchogenic cyst. On pathological examination, the internal, heterogeneously hypoechoic, ball-like lesion was found to be mucous material within the cyst. To our knowledge, this is the first reported case of a presternal subcutaneous bronchogenic cyst presenting with a ball-like lesion inside of the cyst. This unusual ultrasonographic feature can be a clue to the diagnosis of subcutaneous bronchogenic cyst. In conclusion, if an anechoic cyst containing an internal, well-circumscribed, hypoechoic ball-like lesion is seen in the presternal subcutaneous fat layer, subcutaneous bronchogenic cyst should be considered in the differential diagnosis of subcutaneous cystic masses.

    Thirty-five consecutive patients with small cell bronchogenic carcinoma (SCBC) received chemoimmunotherapy with VP-16-213, Ifosfamide, vincristine, Adriamycin, and Corynebacterium parvum. Of 33 evaluable patients, 26 (79%) responded with complete (55%) or partial (24%) remissions. Complete remissions were more common among patients with limited disease (11/14 patients, 79%) compared with those with extensive disease (7/19 patients, 37%) and among patients (11/14 patients, 79%) compared with those with extensive disease (7/19 patients, 37%) and among patients who were ambulatory prior to therapy (16/25 patients, 64%) compared with those who were nonambulatory (2/8 patients, 25%). Myelosuppression consisted primarily of neutropenia. Eight percent of the treatment courses in 29% of the patients were associated with hematuria and/or documented episodes of infection during neutropenia. There were three deaths possibly related to treatment, in two of which there was no evidence of disease at post-mortem examination. Six patients relapsed in the central nervous system (CNS). In four instances, CNS relapse was the only site of tumor progression. Central nervous system relapse was more common among evaluable patients who did not receive prophylactic brain irradiation (5/17 patients, 29%, vs. 1/15 patients, 7%; P . 0.23). The median survival duration for all patients was 63 weeks, being slightly longer for patients with limited disease than for those with extensive disease (70.9 weeks vs. 56 weeks; P . 0.18). This was also true for patients who achieved complete rather than partial remissions (71 weeks vs. 50 weeks; P . 0.09). Patients receiving prophylactic brain irradiation experienced longer survival (100.8 weeks vs. 48 weeks; P . 0.01).

    Superior vena cava (SVC) syndrome is not an uncommon occurrence in patients with malignancy and it is often described as a medical emergency. In majority of the cases, SVC syndrome occurs due to mechanical obstruction of the SVC by extraluminal compression with primary intrathoracic malignancies. However, intraluminal obstruction due to thrombosis can also produce symptoms and signs of SVC syndrome. Clot-related SVC obstruction is mostly associated with indwelling central venous catheter and pacemaker leads, although such thrombosis can occur spontaneously in a background of a hypercoagulable state, e.g., malignancy. Here, an unusual case of sudden onset SVC syndrome has been reported, which on initial radiologic evaluation was found to have a lung nodule without any significant mediastinal mass or adenopathy compressing SVC. Subsequent investigation with Doppler ultrasonography of the neck showed thrombosis in the right internal jugular, right subclavian and right brachiocephalic vein, which was responsible for SVC syndrome. Histopathological evaluation of lung nodule confirmed presence of an adenocarcinoma. Therefore, venous thromboembolism as a paraneoplastic syndrome should be kept in mind while evaluating a case of SVC obstruction in a cancer patient. Management of the underlying disease is of prime importance in such cases and anticoagulation is the mainstay of therapy. Ability to identify paraneoplastic syndrome may have a significant effect on clinical outcome, ranging from early diagnosis to improved quality of life of the patient.

    The most common location of bronchogenic cysts is the mediastinum, adjacent to the major airways. Endotracheal bronchogenic cysts are rare and most present in infancy with respiratory failure. Although surgical resection has remained the treatment of choice, there is increasing interest in the management of these cysts with therapeutic aspiration alone. In this article, we describe a 68-year-old man with endotracheal bronchogenic cyst who was managed with endobronchial ultrasound-guided needle aspiration. We also systematically review the literature for reports of endotracheal bronchogenic cysts. The review identified 9 reports (10 patients) with endotracheal bronchogenic cysts. The most common age at presentation was infancy (n=8) and surgical resection was the most common treatment modality used (n=7).

    In the first part of this study we have shown how the serum levels of four selected tumour markers, namely tissue polypeptide antigen (TPA), carcino-embryonic antigen (CEA), hyaluronic acid (HA) and ferritin, display patterns characteristic of mesothelioma (M) or bronchogenic carcinoma (BC) in asbestos-exposed workers, and we hypothesize that the differences in marker patterns correspond to differences in carcinogenesis mechanisms. In a preliminary study, we found these specific marker patterns in 5/19 exposed workers of whom only one demonstrated any radiological signs of disease. Thus these specific marker patterns may be early events, occurring long (possibly years) before the classical radiological signs of exposure to asbestos. Accordingly they afford an optimal opportunity for prevention which should be adapted to the carcinogenesis mechanism as it is revealed by the marker pattern; it is aimed at antagonizing free radical carcinogenesis in all persons with TPA levels in excess of 100 U/l or Ferritin in excess of 400 ng/ml, and at inhibiting chemical carcinogenesis in those having elevated CEA levels (over 3 ng/ml). The mechanisms involved in these inhibitory processes are described and discussed, as well as the practical implementations that proceed from them. A prevention trial is now being started among 300 active and retired workers of an asbestos-cement works in northern France; the design of the study is presented. This prevention programme should be maintained over many years and holds a strong potential for reducing the untoward effects of exposure to asbestos.

    Bronchogenic cyst (BC) is a rare congenital malformation of the lung. Most patients remain asymptomatic until adulthood while some are symptomatic in the first few years of life. However, symptoms in newborn period are rare. We report a case of a 3-day-old preterm baby with respiratory distress diagnosed as congenital lobar emphysema on chest X-ray. A CT scan revealed a mediastinal cyst causing obstructive lobar emphysema. The cyst was excised and pathological examination was suggestive of BC.

    Four patients with mediastinal masses are described. CT examinations demonstrated masses of high attenuation, and solid masses were suspected. At thoracotomy each patient had a cystic mass containing a brownish, turbid, mucoid material. The pathologic diagnosis in each case was a bronchogenic cyst. The possibility of such a cyst should not be excluded because of a high CT number, which reflects the turbid contents of the cyst.

    Spinal bronchogenic cysts are rare congenital lesions. The authors describe their experience in the treatment of a 17-year-old boy who presented with back pain and paresthesia in both lower extremities. Lumbar MR imaging revealed the presence of an intramedullary cystic lesion at the conus medullaris and histopathological analysis revealed a bronchogenic cyst. To the best of the authors' knowledge, this is the first report of an intramedullary spinal bronchogenic cyst arising at the conus; all previously reported spinal bronchogenic cysts were either intradural extramedullary or not located at the conus.

    Primary cardiac tumours are rare in the paediatric age group. Bronchogenic cysts, although relatively rare, represent the most common cystic lesion of the mediastinum. Intracardiac bronchogenic cysts however, are extremely rare. The authors are unaware of any case previously reported in a Nigerian child and hence report the case of a 2-year-old boy for its rarity and interest. The boy was referred for evaluation of a cardiac murmur. Clinical, radiological and electrographic findings were suggestive of mild pulmonary stenosis or an atrial septal defect (ASD). 2-dimensional echocardiography however, revealed in addition to a small ASD, an intracardiac mass attached to the tricuspid valve. The mass was surgically removed and found on histology to be a bronchogenic cyst. Our experience highlights the importance of echocardiography in the evaluation of asymptomatic patients with cardiac murmurs, in whom a rare lesion might have otherwise been missed. PMID:22605814

    The authors have encountered four cases of oil aspiration pneumonia complicated by carcinoma. Each had a clear-cut history of chronic intake of an oily substance, radiographic changes, and histologically documented oil aspiration pneumonia. Lung cancer later appeared in the involved area. A small number of similar cases also have been reported. The implication is that oil aspiration pneumonitis may induce bronchogenic carcinoma, particularly either the alveolar cell or the squamous cell variety. The radiographic diagnosis of the malignant transformation is difficult, and consequently the prognosis is poor.

    Bronchogenic cysts are rare congenital anomalies result of abnormal development of the tracheobronchial tree. They develop in the lung parenchyma or in the mediastinum. For a period of 17 years (1975-1991) a total of 46 children with bronchogenic cysts have been treated; in 6 the cysts were localized in the mediastinum. Two patients were one-year-old, 3 were in the age group 1 to 3 years and 1 was older than 3 years. Four patients were boys and 2 girls. Two children had hacking cough and attacks of dyspnea; one had swallowing difficulties. In 3 children the disease produced no symptoms and was detected on examination for pneumonia (1 child) and acute upper respiratory tract infection (2 children). All children had conventional X-ray; 5 had esophagography as well, 4--computer axial tomography, 3--echography. All children were operated (total extirpation of the cyst) and left the hospital cured.

    Small cell neuroendocrine carcinoma (SNEC) is a rare form of malignancy. It mainly presents as bronchogenic neoplasm, and the extrapulmonary form accounts for only 0.1% to 0.4% of all cancers. These extrapulmonary tumors have been described most frequently in the urinary bladder, prostate, esophagus, stomach, colon and rectum, gall bladder, head and neck, cervix, and skin. Primary SNEC of the sinonasal tract is extremely rare with only less than 100 cases reported in the literature. Because of extreme rarity and aggressiveness of the tumor, the management for this entity varies considerably mandating multimodality approach. In this paper, we report a patient presented with left-sided facial swelling, and the histopathologic examination confirmed primary SNEC of left sinonasal tract. The tumor involved multiple paranasal sinuses with invasion into the left orbit and left infratemporal fossa and metastasized to cervical lymph nodes and bone. The patient encountered devastating outcome in spite of optimal medical management and treatment with palliative chemotherapy highlighting the necessity for further research of primary SNEC of head and neck.

    Ameloblastic carcinoma is a rare odontogenic tumor exhibiting histological evidence of malignancy in the primary or recurrent tumor. It is characterized by rapid, painful expansion of the jaw, unlike conventional ameloblastomas. The tumor most frequently involves the mandible. The expanding lesion causes perforation of the buccal and lingual plates of the jaw and invades the surrounding soft tissue. Rapidly growing large tumor mass may cause tooth mobility. A mandibular tumor involving the mental nerve leads to paresthesia of the nerve. A maxillary tumor can produce a fistula in the palate and paresthesia of the infraorbital nerve. Most ameloblastic carcinomas are presumed to have arisen de novo with a few cases of malignant transformation of ameloblastomas. Although rare, these lesions have been known to metastasize, mostly to the regional lymph nodes or lungs. A case of ameloblastic carcinoma in a 60-year-old man is reported here and its clinical, radiological and histological features are discussed. PMID:24579073

    A case was a 46-year-old woman who presented with the left breast lump confirmed about 30 years ago. In August 2006, the patient came to our hospital for consultation due to her breast lump was enlarged. Mammography revealed a frequent occurrence of the mass shadow of marginal irregularity and we diagnosed it with category 4. Breast echography showed a lot of irregular lesions. Even breast MRI presented a multiple mass-related lesion. The malignancy was possible, and a needle biopsy diagnosed them to be mucinous carcinoma. Pectoralis muscle preservation mastectomy and sentinel lymph node biopsy technique were used for surgery. Histopathology also diagnosed it to be mucinous carcinoma, T2N0 M0, stage IIA, ER (+), PgR (+), HER2 score 0. It has been 4 years since the operation but no sign of recurrence/metastasis was observed at present. There have been few reports of breast cancer with multiple cases, mucinous carcinoma as a case in point. Therefore, we report the invaluable case in addition to some paper consideration with it.

Giant basal cell carcinoma is a rare form of basal cell carcinoma, more aggressive and defined as a tumor measuring more than 5 cm at its largest diameter. Only 1% of all basal cell carcinoma develops to a giant basal cell carcinoma, resulting of patient's negligence. Giant basal cell carcinoma is associated with higher potential of metastasis and even death, compared to ordinary basal cell carcinoma. We report a case of giant basal cell carcinoma metastaticin lung occurring in a 79 years old male patient, with a fatal evolution after one course of systemic chemotherapy. Giant basal cell carcinoma is a very rare entity, early detection of these tumors could prevent metastasis occurrence and improve the prognosis of this malignancy. PMID:27795755

    Among 50 patients with small cell bronchogenic carcinoma who were placed on a protocol of combined chemotherapy and radiation therapy, seven patients developed recurrence in the spinal cord. Five cases terminated in paraplegia and death. One patient with pontine recurrence recovered with local radiation therapy. One patient, diagnosed early, responded to local radiation therapy and is ambulatory. Methods of diagnosis were myelogram, computerized axial tomography, cerebro spinal fluid, chemistry and cytologies. The poor prognosis and the difficulty of diagnosis suggest that prophylactic therapy of the entire cranio-spinal axis should be evaluated.

    Acantholytic squamous cell carcinoma is a well-defined variant of squamous cell cancer in which significant portions of the neoplastic proliferation show a pseudoglandular or tubular microscopic pattern. It usually presents as a nodule with various colors, and it is accompanied by scaling, crusting, and ulceration on the sun-exposed areas of older aged individuals. Histologically, the tumor consists of a nodular, epidermal-derived proliferation that forms island-like structures. At least focally or sometimes extensively, the tumor cells shows a loss of cohesion within the central gland-like or tubular spaces. This tumor resembles the structure of eccrine neoplasms, but it is negative for dPAS, CEA and mucicarmine and it is only positive for EMA and cytokeratins. Herein we report a case of acantholytic squamous cell carcinoma that occurred on the face of an 82-year-old woman. PMID:27303210

    Difficult to treat asthma is an asthma syndrome that brings in our mind other differentials. Mediastinal masses are not common findings, but are important variables. Bronchogenic cyst is a congenital anomaly of the foregut that is typically found in the mediastinum and diagnosed accidentally. We present a 4-year-old girl with allergic asthma that began at 8-months of age and finally a bronchogenic cyst was detected in this patient. The patient had history of asthma since she was eight months old. She had a history of several asthma attacks which had partly responded to asthma management. During the last episodes of asthma attacks, she was hospitalized in Pediatric Intensive Care Unit. Imaging studies showed a 4x3 cm mass in the posterior part of the thoracic cavity that had led to tracheal narrowing was found for which the patient underwent thoracotomy and in surgical exploration a cyst that had compressed the thoracic trachea. Pathological examination of the cyst revealed a bronchogenic cyst. Bronchogenic cyst is an uncommon developmental abnormality but in a patient with obstructive pattern of airways it should be considered in differential diagnosis of asthma, especially if the asthma management is not successful.

    Carcinoma in the external auditory canal (EAC) is a rare malignancy with an annual incidence of one per one million people, accounting for less than 0.2% of all head and neck cancers. The most common histopathological type of EAC cancer is squamous cell carcinoma. Verrucous carcinoma is a well-differentiated, low-grade variant of squamous cell carcinoma. It is a locally destructive, invasive, and slow growing tumor that rarely metastasizes. Verrucous carcinoma occurs predominantly in the oral cavity and larynx, and its occurrence in the EAC is extremely rare. In this report, we present a histologically confirmed case of verrucous carcinoma in the EAC and temporal bone, which for several years had been classified as epithelial hyperplasia. Two-and-a-half years after diagnosis of verrucous carcinoma, a recurrent mass was found and the lesion was then confirmed to be squamous cell carcinoma. PMID:27942606

    Lymphoepithelioma-like carcinoma carries similar histopathological features with lymphoepithelioma typically located in the nasopharynx. Lymphoepithelioma-like carcinoma of the breast can be mistaken for breast lymphoma or medullary carcinoma due to the undifferentiated appearance of tumor cells and presence of prominent lymphoid component. Lymphoepithelioma-like carcinoma is rare, and the similarity between medullary carcinoma of the breast makes it difficult to distinguish these two tumors. In the presented case, neither lymph node nor distant metastases were detected. Breast lymphoepithelioma-like carcinoma is extremely rare with only 21 reported cases in the literature. Herein we present a 59-year-old woman with lymphoepithelioma-like carcinoma of the breast along with the cases previously published in the literature.

    Primary squamous cell carcinoma of the thyroid gland is rare, and mixed squamous cell and follicular carcinoma is even rarer still, with only a few cases reported in the literature. The simultaneous presentation of three primary cancers of the thyroid has not been reported previously. Here we report a case of primary squamous cell carcinoma of the thyroid, follicular thyroid carcinoma, and micropapillary thyroid carcinoma. A 62-year-old female patient presented with complaints of pain and a 2-month history of progressively increased swelling in the anterior region of the neck. Fine-needle-aspiration cytology of both lobes indicated the possibility of the presence of a follicular neoplasm. Total thyroidectomy with left-sided modified radical neck dissection was performed. Postoperative pathological examination confirmed the diagnosis of thyroid follicular carcinoma with squamous cell carcinoma and micropapillary carcinoma of the thyroid. Thyroid-stimulating hormone suppressive therapy with l-thyroxine was administered. Radioiodine and radiotherapy also were recommended, but the patient did not complete treatment as scheduled. The patient remained alive more than 9 months after operation. The present case report provides an example of the coexistence of multiple distinct malignancies in the thyroid.

    Summary Background Metaplastic breast carcinoma is an uncommon type of breast cancer that usually appears as a large, fast growing breast lump. Case Report We report 3 cases of metaplastic breast carcinoma presented at our clinic in 2014. The mean age at diagnosis was 67.3 years. 1 patient presented with a fast growing, large mass detected by herself. However, in the other 2 patients, the nodule was approximately 1.5 cm in size, not fast growing, and was detected on mammography. All 3 patients were treated surgically (2 lumpectomies and 1 mastectomy), with the final pathology of metaplastic carcinoma with chondroid mesenchymal differentiation in 2 cases and metaplastic carcinoma with myoepithelial differentiation in the 3rd case. The patients are still under adjuvant therapy. Conclusions Metaplastic breast carcinoma may present unusually as a non-palpable lump. This entity must be considered in any breast lump. PMID:26989360

    A case of primary hepatocellular carcinoma metastatic to the gingiva is described. Hepatocellular carcinoma is an uncommon malignancy, generally occurring in a cirrhotic liver, which rarely metastasizes to the maxillofacial area. Of eight such cases in the English-language literature, the present case is the fourth involving metastasis to the gingiva. Hepatocellular carcinoma would seem to metastasize with equal frequency to the gingiva and to the mandibular bone. In the case described, histologic examination of the gingival lesion definitively established the diagnosis following somewhat equivocal results of needle biopsy of the liver.

    2016-12-01

    Basosquamous carcinoma is a rare cutaneous tumor considered by some authors as an aggressive type of basal cell carcinoma having a propensity for local recurrence and a potential risk for regional and distant metastatic spread. Herein we present 2 cases of basosquamous carcinoma of head and neck region, with metastatic spread to parotid gland (case 1) and to cervical nodes (case 2). Both patients had recurrence 2 years after initial treatment of the primary lesion (first patient: surgery; second patient: radiotherapy) and at the same time developed regional metastases. We conclude that basosquamous carcinoma must be considered as an aggressive variant of basal cell carcinoma having a great propensity to metastasize even at an early tumor stage. The clinical features, the morphologic aspects, and the treatment of this rare entity are discussed in this article.

    Abstract Rationale: Tumors with multiple histological features, such as adenocarcinomas and neuroendocrine carcinomas, were included as a new category of neuroendocrine carcinomas in the 2010 World Health Organization classification. We recently experienced a rare case of a pancreatic carcinoma with both adenocarcinoma and neuroendocrine carcinoma components, a so-called mixed adenoneuroendocrine carcinoma. Patient concerns and diagnosis: A 66-year-old man was referred to our hospital with obstructive jaundice. Contrast-enhanced computed tomography images indicated a tumor located at the pancreatic head measuring 3.0 × 2.5 cm in diameter and invading the common bile duct. Cytological examination of the bile juice obtained by endoscopic retrograde cholangiopancreatography revealed adenocarcinoma cells. Pancreaticoduodenectomy was performed safely as radical resection. Interventions: Microscopically, the resected tumor consisted of tightly intermingled adenocarcinoma and neuroendocrine carcinoma components. On the immunohistochemical examination, p53 was ubiquitously positive in both components, whereas chromogranin A, synaptophysin and neuron-specific enolase, neuroendocrine markers, were limited to the neuroendocrine carcinoma component. Outcomes: Thus, such features of both adenocarcinoma and neuroendocrine carcinoma observed microscopically and immunohistochemically seemed to indicate a composite tumor. Lessons: The findings of this case suggest that adenocarcinoma and neuroendocrine carcinoma may be derived from a single cancer stem cell. PMID:28248881

    We describe the fifth case of mucoepidermoid carcinoma. The patient had penile ulcer with bilateral inguinal and pelvic lymphadenopathy and underwent total penectomy. After antibiotic therapy, the patient began outpatient chemotherapy, but the treatment was discontinued due to his intolerance. The patient died due to infectious complications of the inguinal lymphatic fistula 7 months after the histological diagnosis. Notably, the periurethral area was involved in the anatomopathological evaluation of the excised penis. The penile mucoepidermoid carcinoma was aggressive and the perimeatal region was involved. This case helps demystify the origins and prognosis of this rare case. More reports documenting patient characteristics and their evolution with penile mucoepidermoid carcinoma are needed.

    Thyroid carcinoma mandibular metastasis are not very frequent and the cases described in literature are few. Due to its bloodstream dissemination, most of them are a consequence of the follicular variant of thyroid carcinomas. A case is presented and a review of the clinicopathologic characteristics of the lesion is made, so the oral and maxilofacial surgeon can recognize it, make a correct differential diagnosis with other mandibular radioluciencies and in consequence, carry out an adequate treatment.

    Follicular carcinoma of thyroid is the second most common type of carcinoma of thyroid, and it may metastasize to bone, lung, brain, and skin. However, the initial presentation of follicular carcinoma of the thyroid as a large intrathoracic mass without any symptoms of thyroid gland enlargement and dysfunction is very rare. We hereby report a case of a 50-year-old male who presented with chief complaints of chest and low back pain. Preliminary evaluation led to the provisional diagnosis of left-sided intrathoracic mass with vertebral metastasis which was suspected to be a case of bronchogenic carcinoma with distant metastasis. Surprisingly, transthoracic biopsy and histopathology revealed metastasis from follicular carcinoma of thyroid. This prompted us for a retrograde evaluation for a primary thyroid malignancy for which an ultrasound and contrast enhanced computed tomography (CECT) of the neck was done which confirmed the presence of a solitary thyroid nodule. Ultrasonography-guided fine-needle aspiration cytology of the nodule revealed follicular carcinoma of thyroid. Histopathological evaluation subsequent to total thyroidectomy revealed follicular carcinoma thyroid, further confirming the diagnosis. The patient was then referred to Department of Nuclear Medicine and Radiotherapy for radionuclide ablation and chemotherapy. We chose to report this case because of its rare presentation as a large intrathoracic mass and the retrograde diagnosis of follicular carcinoma of thyroid. To the best of our knowledge, this is the first report of such a rare case.

    We report a case of adenosquamous carcinoma of the colon. A 70-year-old woman underwent a colonoscopic examination because of a positive fecal occult blood test. Colonoscopy demonstrated a type 2 tumor of the ascending colon, and a biopsy specimen showed poorly-moderately differentiated tubular adenocarcinoma. We performed a right hemicolectomy with D2 lymphadenectomy. The histopathology of the tumor demonstrated adenosquamous adenocarcinoma. Primary adenosquamous carcinoma of the colon is relatively rare and has a poor prognosis. Therefore, adenosquamous carcinoma of the colon may require strict follow-up.

    Small cell neuroendocrine carcinoma of uterine cervix is a rare variant of cervical carcinoma with features of high aggressiveness. It is difficult to manage these tumors. It is often diagnosed at an advanced stage and its prognosis is generally poor. The present report describes a 65 year old woman who presented with postmenopausal bleeding and had a friable polypoidal growth hanging from the cervix. Microscopic examination of the growth showed features of small cell carcinoma. Neuroendocrine cellular characteristics were assessed by using antibodies against neuron specific enolase. The case is being reported to create awareness of this rare entity

    Median ectopic thyroid may be encountered anywhere from the foramen caecum to the diaphragm. Non lingual median aberrant thyroid (incomplete descent) usually found in the infrahyoid region and malignant transformation in this ectopic thyroid tissue is very rare. We report an extremely rare case of papillary carcinoma in non lingual median aberrant thyroid in a 25-year-old female. The differentiation between a carcinoma arising in the median ectopic thyroid tissue and a metastatic papillary carcinoma from an occult primary in the main thyroid gland is also discussed.

    The paper deals with a case of a most probable metastatic carcinoma, found in skeletal remains of a 35-45 year old female who lived in Sayala, Egyptian Nubia, during the Christian Period. The macroscopic and radiographic morphology supported by microscopic investigation by M. Schultz (Göttingen) revealed the predominating osteoclastic process in the lesions, combining with the slightly expressed osteoblastic component. Single lesions located in the skull, spine, sacrum, sternum, ribs, clavicle, scapula, radius, metacarpals and hand phalanges, ossa coxae, femur and tibia were described. Of the various differential diagnostic possibilities, the diagnosis was focused on distinction between myeloma multiplex and lytic metastatic carcinoma. The growing evidence of incidence of metastatic carcinoma, its relative frequency compared with that of myeloma multiplex, and the most probable primary source of metastases of our case--the carcinoma of the breast--were discussed.

    Gallbladder carcinoma (GBC) is an uncommon malignancy with a high mortality rate. Detecting gallbladder carcinoma in its early stages can be difficult, despite improvements in ultrasound and computed tomography (CT) imaging. Most diagnoses of GBC are made at advanced stages, with the majority being found incidentally during surgery for cholelithiasis. The presented case demonstrates the difficulty of diagnosing GBC preoperatively in its early stages.

    We report a rare case of microcystic transitional cell carcinoma involving the urinary bladder, in a 38-year-old man, and we add our experience in the treatment of this neoplasm. The tumor was muscle invasive, and a radical cystectomy was performed. The patient received no postoperative chemotherapy or radiotherapy, and he has not signs of local recurrence or distal metastasis after 3 years of intense follow up. Even though the number of cases documented so far, is insufficient to draw safe conclusions regarding the optimal treatment of the microcystic variant of transitional cell carcinoma. Our case indicates that even in cases of microcystic transitional cell carcinoma with infiltrative nature, aggressive therapy is associated with good control of the disease locally and distally.

    Pineal metastasis is uncommon and most metastatic pineal lesions are asymptomatic. To our knowledge the herein reported case is the first in which the pineal gland was confirmed as the metastatic site of a bladder carcinoma.The patient reported in this case is a 59-year-old man who suffered from headache and delirium for 4 days after surgical treatment for removal of a bladder carcinoma 1 year ago. Magnetic resonance imaging (MRI) revealed a solid tumor involving the pineal gland with significant enhancement.The patient underwent surgical treatment for removal of the neoplastic lesion in the pineal gland. Histopathological examination confirmed invasion of the pineal gland by metastatic urothelial carcinoma.This case highlighted that the presence of pineal lesions in patient with known malignancy should raise suspicion of metastatic involvement.

    Malignant transformation of the epithelial component of phyllodes tumours (PT) is rare and only reported in literature as sporadic cases of carcinoma associated with PTs. We report the clinicopathological characteristics of in situ and invasive carcinoma coexisting with PT in 10 patients treated in our institution over an 11-year period from 1992 to 2012. Ten patients with coexisting PT and in situ or invasive carcinoma were identified from our records. Six had carcinoma found within the PT. All were female with a median age of 47 (43-72) years. One patient had a history of PT in the same breast while another had a history of PT in the same breast as well as invasive ductal carcinoma in the contralateral breast. The rest did not have any risk factors of breast cancer. Five patients had a preoperative core needle biopsy performed with the report of a fibroepithelial lesion. The rest of the patients had surgery upfront for their breast masses. Two patients who had ER/PR positive invasive carcinoma received adjuvant hormonal therapy. Patients were followed up for a mean of 3.6 years (9 months-10 years) and all patients were alive and recurrence free. PT associated with carcinoma is rare, and we present a series of cases that add to the limited current literature. It is often difficult to detect the presence of the carcinomatous component preoperatively. Hence, close examination of resected PT specimens must be carried out to allow prompt detection of any associated carcinomas, however rare, such that adequate treatment can be given.

    In 2 years 53 patients with tumors of the tracheobronchial tree have been treated by photocoagulation therapy. Forty cases of them were with different types of cancer and 13 cases with benign lesions of the trachea or bronchi. As a laser source we used an Nd:YAG laser, MBB, Germany. At first the tumor was irradiated with a power of 25 - 30 W, following power up to 90 W. The median energy dose was 3,500 J/sq cm for each patient. The treatment was executed under local anesthesia with a rigid or flexible bronchoscope. In all of the cases with benign tumors we obtained a stable positive effect. In 15 cases of carcinoma we attained a recanalization and restoration of the ventilation to the treated area -- 37.5%. The only complication due to the procedure was the death of one patient with a tracheal cancer and myasthenia gravis. Photocoagulation therapy is an effective method for benign tumors. In cases with carcinoma this therapy is used with palliative purpose -- recanalization of the bronchus. Laser endobronchial therapy shows an immediate positive effect in the treatment of airway obstruction.

    Urothelial carcinoma has numerous histological variants, and these variants may coexist in a single case. Here, we present a case of a 70-year-old man with urothelial carcinoma of the bladder with a maximal diameter of 5 mm that involved micropapillary and plasmacytoid variants, with villoglandular differentiation. The presence of these variants was confirmed by pathological examination of a transurethral resection specimen, and high-grade urothelial carcinoma was found as a minor component. Although this bladder carcinoma was classified as pT1, cystoprostatectomy, urethrectomy, and lymphadenectomy were performed due to the presence of the micropapillary and plasmacytoid variants, which are known to be aggressive. Examination of a surgically resected specimen revealed no carcinoma. A transition between urothelial carcinoma in situ and non-invasive micropapillary carcinoma was found to be a pivot point connecting the diverse morphologies of this bladder carcinoma, from which there existed two pathways. One pathway was from urothelial carcinoma in situ to the plasmacytoid variant through invasive high-grade urothelial carcinoma, and the other was from non-invasive micropapillary carcinoma to urothelial carcinoma with villoglandular differentiation or to the micropapillary variant. This is the 16th reported case of urothelial carcinoma with villoglandular differentiation in the literature. As urothelial carcinoma with villoglandular differentiation is often associated with aggressive variants, as shown in our case, it should be reported whenever encountered in routine pathological practice.

    Mammary analog secretory carcinoma (MASC) is a recently described rare neoplasm that was first reported in the salivary gland with an associated ETV6-NTRK3 fusion. We present a case of MASC involving and presumably arising in the thyroid, which was originally diagnosed as papillary thyroid carcinoma on fine needle aspiration and surgical resection. The later correct diagnosis of MASC was confirmed by immunohistochemistry and molecular studies. The cytopathological features of MASC in the salivary gland are previously described; however, we present the first cytopathological description of MASC arising in the thyroid with the unique feature of prominent nuclear grooves. Differentiating MASC from overlapping features of cytopathologic mimics such as papillary thyroid carcinoma may carry crucial therapeutic implications. Diagn.

    Introduction We report a rare case of a 23-year-old male who presented with abdominal discomfort for 15 days. An ultrasound was performed which showed a hypoechoic, heterogenous mass in the left lobe of the liver and distended portal vein, followed by further investigation with computed tomography (CT), MRI, and MRA. Serum alpha-fetoprotein was not elevated and hepatitis B antigen was negative. Methods CT scan depicted a nodular mass in left liver lobe with occlusion of both the central part and the two main branches of intrahepatic portal vein. Result Biopsy of the liver mass led to a diagnosis of fibrolamellar hepatocellular carcinoma. Conclusion Fibrolamellar carcinoma is an uncommon variant of hepatocellular carcinoma. The diagnosis is suggested by radiographic studies and is confirmed by histological examination. PMID:19960280

    The palliative treatment of developed primary or recurrent rectum carcinoma is still an important issue in treatment of this disease. The aim of the surgery is in such case to remove the tumorous obstacle and to prevent the development of ileus, to reduce pain, to limit the volume of tumorous tissue, to prevent bleeding and possible incontinence or mucous secretion. The transanal laser thermodestruction of the tumor represents one of the possible ways of palliative treatment of rectum carcinoma. The method is very considerate even for the high risk patients. On the other hand it requires a short-term hospitalization. The method of transanal laser evaporisation of carcinoma is also important from the ethical point of view: in many cases it may prevent the creation of palliative derivative colostomy. This fact is very important especially in patients with the terminal stage of the malign carcinoma because they live the rest of their lives in acceptable conditions. The important benefits are described in three case histories. The method is presented as an urgent surgery in solution of ileus which is based on tumorous rectum stenosis.

    Cutaneous metastasis (carcinoma en cuirasse) is a condition that results from a tumor spreading via lymphatic or vascular embolization, direct implant during surgery or skin involvement by contiguity. Contralateral distant cutaneous breast cancer has never been reported before and hence, the nature and management of such rare cases remains challenging. We aim to present a case of left-sided 'distant' cutaneous metastatic invasive duct carcinoma affecting the distal upper extremity (contralateral side) two and half years (disease-free) following treatment for right breast cancer (right mastectomy + chemoradiation). A complete metastatic work-up excluded the presence of any underlying disease. Clinical examination revealed a fungating, irregular ulcer that bled easily on touch involving the left forearm. The ulcer was excised totally and the raw area reconstructed using a split thickness graft. The patient had uneventful postoperative course and now remains disease-free for almost 1 year with no evidence of local recurrence.

    Summary Urachal carcinoma is a rare tumor that has not been well studied. To determine the pathologic and clinical features of this disease, we retrospectively evaluated 46 cases from our surgical pathology files. The patients included 16 women and 30 men, with a mean age of 53.4 years (range, 28–82 years). Forty patients had undergone cystectomy, and the remaining 6 had undergone transurethral bladder biopsy. Most tumors were located at the dome (n=44); only 2 were located at both the dome and anterior wall. All tumors consisted of adenocarcinoma, including mucinous (n=36), enteric (n=7), not otherwise specified (n=2), and signet ring cell (n=1) types. Focal areas of signet ring cell features were present in 23 cases, but urothelial carcinoma in situ was not identified in any cases. The tumors invaded the muscularis propria (n=8), perivesical adipose tissue (n=27), and abdominal wall (n=3). Twenty-five patients had died of cancer at a mean of 32 months (range, 12–74 months), and 21 patients were alive at a mean of 65 months (range, 7–230 months). The median cancer-specific survival time of urachal adenocarcinoma patients was 45 months, which was significantly longer than that of bladder urothelial carcinoma patients with similar-stage disease (p=0.047). Patients’ cancer-specific survival was associated with tumor stage according to the Sheldon, Mayo, and TNM staging systems. In conclusion, urachal carcinomas are predominantly composed of invasive adenocarcinomas, which commonly demonstrate mucinous features. Most tumors present at advanced stages but are still associated with a better survival rate than bladder urothelial carcinomas. PMID:26364859

    We report a case of papillary carcinoma of the duodenum combined with right renal carcinoma. A 58-year-old man underwent a physical examination that revealed intrahepatic and extrahepatic bile duct dilatation on B ultrasound. Intrahepatic bile duct dilatation could be seen on magnetic resonance imaging (MRI), but the head of the pancreas and distal bile duct showed no tumor signals, which led to a diagnosis of periampullary carcinoma and right renal carcinoma. Considering the trauma of pancreaticoduodenectomy combined with renal resection operation is greater, we carried out the laparoscopic right renal radical resection first, and then a pylorus-preserving pancreaticoduodenectomy was performed. However, postoperative intra-abdominal infections and bleeding occurred; our patient improved after vascular interventional microcoil embolization for the treatment of hemostasis. The second operation for celiac necrotic tissue elimination, jejunal fistulization and peritoneal lavage and drainage was performed 14 days latter. Our patient improved gradually and was discharged on the 58th postoperative day. There has been no tumor recurrence after a follow-up of 26 months.

    Matrix-producing carcinoma (MPC) is an uncommon variant of metaplastic carcinoma. It was first described by Wargotz and Norris in 1989 as invasive breast carcinoma with direct transition to cartilaginous stroma without intervening spindle cell component. Since then, several studies, mostly in the form of case reports or case series, have been reported and the origin of tumor cell, importance of appropriate terminology for the tumor, histopathological differential diagnosis, benign breast lesions that the tumor could correlate with, and prognosis and consequently the treatment modalities have been discussed. A 43-year-old woman referred to our clinic with a lump in her left breast. Physical examination and radiological findings were consistent with malignancy. Core biopsy of the lesion was reported as “invasive breast carcinoma” and then breast-conserving surgery with sentinel lymph node dissection were performed. The case was diagnosed as MPC of the breast. The literature findings imply epithelial cell (ductal and/or myoepithelial) nature of this tumor. The prognosis is still controversial. Histopathological evaluation of sufficiently sampled surgical excision material is important to recognize and make a correct diagnosis.

    Small cell carcinoma of the prostate is associated with poor prognosis and different treatment from conventional acinar adenocarcinoma. Given the important clinicopathologic implications of a diagnosis of small cell carcinoma, we report 7 cases showing unusual, extensive small cell-like change in intraductal carcinoma and invasive carcinoma. Prostatic biopsies from 3 patients and radical prostatectomy specimens from 4 patients showed variably extensive small cell-like high-grade prostatic intraepithelial neoplasia and intraductal carcinoma. Five cases were associated with conventional acinar adenocarcinoma (2 cases with Gleason score 4 + 3 = 7; 3 cases with Gleason 3 + 4 = 7). No small cell carcinoma was seen. Small and large ducts with small cell-like change showed solid and cribriform proliferations of atypical cells with abrupt transition between centrally located populations of small cells and more typical large dysplastic cells at the duct periphery. Rosette-like formations were noted within some involved ducts. Small cell-like change was characterized by crowded cells with uniformly bland vesicular nuclei and minimal cytoplasm and no significant mitotic or apoptotic activity. In 3 cases, similar small cell-like morphology was noted focally in invasive carcinoma. The small cell-like areas were negative for synaptophysin and chromogranin, focally positive for TTF-1, and weakly positive for racemase. Ki-67 labeled less than 5% with predominant labeling of the larger atypical cells and minimal reactivity in the small cell-like population. In summary, small cell-like change in prostatic intraepithelial neoplasia, intraductal carcinoma, and invasive carcinoma is not associated with small cell carcinoma; shows no immunohistochemical evidence of neuroendocrine differentiation; and likely is not an adverse prognostic feature.

    The authors investigated alpha-1-antitrypsin and pregnancy associated alpha-2-glycoprotein at diagnosis and follow-up of patients with bronchogenic carcinoma. Both proteins were determined by single radial immunodiffusion according to Mancini in 60 patients with bronchogenic carcinoma, in 31 patients with nontumorous respiratory diseases, and in 10 patients with tumour metastases in the lungs. The statistical significance of differences was evaluated using Student's t-test. None of the determined proteins was found to be a specific and sensitive marker of bronchogenic carcinoma. The concentration of alpha-1-antitrypsin is increasing with the growth of the tumour, and the values of pregnancy associated alpha-2-glycoproteins are decreasing at the same time. Alpha-1-antitrypsin can be used in follow-up after tumour resection, where recurrent increase of its concentration may indicate a relapse of the tumour.

    A 7 1-year-old man presented to our hospital with constipation and abdominal pain. Computed tomography of the abdomen and colonoscopy revealed advanced cancer of the transverse colon. The biopsy specimen indicated a highly differentiated adenocarcinoma. The patient underwent extended right hemicolectomy with regional lymph node dissection. Pathological examination showed a neuroendocrine carcinoma (NEC) with concurrent adenocarcinoma of the transverse colon and regional lymph node metastases of the NEC and adenocarcinoma. The histopathological examination confirmed a diagnosis of mixed adenoneuroendocrine carcinoma (MANEC) in accordance with the 2010 WHO Classification of Tumors of the Digestive System. Liver and lung metastases were identified 8 months after the surgery. We administered chemotherapy including 5-fluorouracil, Leucovorin, and oxaliplatin (mFOLFOX) plus bevacizumab, with limited therapeutic effect, as the disease progressed despite treatment. The patient chose best supportive care 13 months after the surgery. Several studies have reported that most patients with adenoendocrine cell carcinoma, including MANEC, experience relapse within 1 year after surgery, and few patients remain disease-free for long periods after surgery. The optimal strategy for the management of MANEC is variable owing to its rarity; only 2 cases of MANEC in the colon, including the present case, have been reported in Japan. It is thus important to gather more evidence on this disease and its management.

    Renal cell carcinoma accounts for 3% of all adult malignant tumors. Common sites of metastases are lungs, bone, liver, brain and adrenal glands. Metastatic disease to the head and neck ranges from 15% to 30%. The 5-year survival rate after nephrectomy is 60%-75%, but with multiorgan metastases the 5-year survival rate is significantly lower, 0-7%. A case is presented of a female patient diagnosed with renal cell carcinoma metastases to the paranasal sinuses, diagnosed and treated at the Department of ENT and Head and Neck Surgery, Zadar General Hospital, Zadar, Croatia. The tumor was surgically removed. Unfortunately, the patient died one year after the procedure due to multiorgan failure. Although metastases of renal cell carcinoma to the head and neck are very rare, it should be first suspected when investigating a metastatic tumor in this region. Surgical excision offers the best hope for long term survival. In case of unresectable tumor, other treatment options should be considered such as radiotherapy, immunotherapy and chemotherapy.

    Primary neuroendocrine carcinoma (PNEC) of breast was an unknown pathologic entity till recently due its rare incidence and lack of definitive criteria for diagnosis. We present a case of PNEC of breast in a middle aged lady. A 34 years lady presented with a breast lump since 1 month, who underwent modified radical mastectomy with axillary clearance. Histopathological diagnoses were infiltrating ductal carcinoma-neuroendocrine (NE) type. Immunohistochemistry showed estrogen, progesterone positivity and NE markers positivity in more than 50% of tumor cells for chromogranin, synaptophysin, neuron specific enolase. On further investigation by whole body computed tomography and magnetic resonance imaging revealed no extra mammary primary tumor. Hence the diagnosis of PNEC of breast was confirmed. Patient received chemo and hormonal therapy and doing well after 6 months of follow up.

    A 5-year-old castrated Japanese domestic cat was presented with persistent vomiting. Ultrasound examinations revealed many masses only in the liver, and the fine needle aspiration was performed. Cytologically, polygonal or oval shaped tumor cells forming rosette and cord-like patterns were demonstrated, and then, the hepatic lesions were diagnosed as neuroendocrine carcinoma tentatively. The cat died one month after admission and was necropsied. Histopathologically, the tumor cells of the hepatic mass were arranged in typical rosette and cord-like structures. They were considerably uniform in size with hyperchromatic round nuclei and eosinophilic cytoplasm. Most of tumor cells were immunopositive for chromogranin A, and some were positive for gastrin. The findings indicate the possibility that the present case was a gastrin-producing neuroendocrine carcinoma.

    Breast carcinoma rarely occurs in cases of foreign body granulomas following liquid silicone injection. Although the Food and Drug Administration (FDA) banned the use of all silicone injection products in 1992, liquid silicone injection for breast augmentation continues to be performed illegally. We herein report a case of breast carcinoma following liquid silicone injection in a 67-year-old female.A total of 45 years after liquid silicone injection, the patient had felt a breast mass in the right breast. Mammography showed a smooth mass that retracted the right nipple. Due to the presence of a marked acoustic shadow caused by the granulomas, evaluating the mass on ultrasonography was difficult. However, magnetic resonance imaging (MRI) showed a lobulated mass under the right nipple. The mass exhibited low signal intensity (SI) on T1-weighted images and intermingled high and low SI on T2-weighted images. Heterogeneous early enhancement with central low intensity was noted on dynamic contrast-enhanced MRI. Several oval-shaped low SI structures in the adipose tissue and disruption of the pectoralis major muscle were also observed. We diagnosed the patient with invasive ductal carcinoma based on a stereotactic-guided Mammotome® (a vacuum-assisted biopsy system manufactured by DEVICOR MEDICAL JAPAN, Tokyo, Japan) biopsy and subsequently performed mastectomy and axillary lymph node dissection (with a positive result for the sentinel node biopsy). Histologically, invasive ductal carcinoma was observed in the silicone granuloma.The development of foreign body granulomas following breast augmentation usually makes it difficult to detect breast cancer; thus, various devices are required to confirm the histological diagnosis of breast lesions. The stereotactic-guided Mammotome® biopsy system may be an effective device for diagnosing breast cancer developing in the augmented breast.

    We report a case of thymic carcinoma presenting as unilateral shoulder pain for 13 months. Before an accurate diagnosis was made, the patient received conservative treatment, cervical discectomies, and myofascial trigger point injection, none of which relieved his pain. When thymic carcinoma was eventually diagnosed, he received total resection of the tumor and the shoulder pain subsided completely. Thymic carcinoma is a rare carcinoma, and our review of the literature did not show shoulder pain as its initial presentation except for one case report. The purpose of this report is to document our clinical experience so that other physiatrists can include thymic carcinoma in their differential diagnosis of shoulder pain.

    Background Merkel cell carcinoma (MCC) is an aggressive cutaneous neuroendocrine carcinoma that affects elderly patients and typically arises in sun-exposed skin. The disease is very rare and only few cases present with no apparent skin lesion. In the retroperitoneum there are only two cases reported in the literature. Case presentation We report a case of a 54-year-old Mexican male with MCC, which presented as a large retroperitoneal mass. Pathological and immunohistochemical analysis of the transabdominal CT-guided biopsy specimen revealed a MCC. The patient underwent preoperative chemotherapy followed by a laparotomy and the mass was successfully excised. Discussion There are two possible explanations for what occurred in our patient. The most plausible theory is the retroperitoneal mass could be a massively enlarged lymph node where precursor cells became neoplastic. This would be consistent with a presumptive diagnosis of primary nodal disease. Moreover, metastasis to the retroperitoneal lymph nodes has been reported as relatively common when compared to other sites such as liver, bone, brain and skin. The less probable theory is the non-described “regression” phenomena of a cutaneous MCC, but we are not found a primary skin lesion. Conclusion Preoperative chemotherapy and excision of the primary tumor is the surgical treatment of choice for retroperitoneal MCC. We propose that further studies are needed to elucidate the true efficacy of chemotherapy in conventional and unconventional patients with MCC. PMID:26708276

  17. Treatment of nevoid basal cell carcinoma syndrome: a case report

    PubMed Central

    2016-01-01

    Nevoid basal cell carcinoma syndrome (NBCCS), also known as Gorlin syndrome, is characterized by various embryological deformities and carcinoma formation. It is caused by PTCHI gene mutations and is autosomal dominantly inherited. Some of the main symptoms of NBCCS are multiple basal cell carcinomas, multiple keratocystic odontogenic tumors (KCOTs) of the mandible, hyperkeratosis of the palmar and plantar, skeletal deformity, calcification of the falx cerebri, and facial defomity. Recurrent KCOT is the main symptom of NBCCS and is present in approximately 90% of patients. In NBCCS, KCOTs typically occur in multiples. KCOTs can be detected in patients under the age of 10, and new and recurring cysts develop until approximately the age of 30. The postoperation recurrence rate is approximately 60%. This case report presents a 14-year-old female patient with a chief complaint of a cyst found in the maxilla and mandible. The patient was diagnosed with NBCCS, and following treatment of marsupialization and enucleation, the clinical results were satisfactory. PMID:27847737

    Cystic neoplasms of the kidney are rare, and present a unique diagnostic challenge. We report the case of an elderly male who presented with a large cystic neoplasm, which was a diagnostic dilemma clinically and radiologically. Histopathological examination showed a tumour composed of variably sized tubules lined by atypical cells having large round nuclei with prominent nucleoli. Hobnailing was seen at places. Tumour cells were immunopositive for pancytokeratin, vimentin, CD10, CK19 and AMACR, confirming a diagnosis of tubulocystic renal cell carcinoma (TC-RCC). PMID:26425234

    Purpose. Penile cancer rarely gives symptomatic skeletal metastases. Methods. We present 2 patients with squamous carcinoma of the penis who were surgically treated for metastases in the femur. Results. Both patients had pathological fractures and were operated on. In one case, the skeletal metastasis preceded any lymphatic spread of the disease, suggesting early haematogenous dissemination. Conclusions. Endoprosthetic reconstruction resulted in pain relief and restored the ambulatory capacity. Clinicians should be aware of the possibility for symptomatic bone metastases with a risk for pathological fracture in patients with penile cancer.

    Background Primary squamous cell carcinomas of the colorectum are very uncommon. Until now, to the best of our knowledge, only 114 cases of squamous cell carcinoma in the colorectum exist in the reported literature. Here we report a case of squamous cell carcinoma of the rectum in the ethnic Kashmiri population in northern India. Case Presentation The case of a 60-year-old male patient (Asian) with a pure squamous cell carcinoma of the rectum is presented here. The patient underwent a curative surgery with concomitant chemotherapy. Two years after the initial curative resection of the tumor he is still alive. Conclusion The prognosis for squamous cell carcinoma of the colorectum is worse than for that of adenocarcinoma, because of the delayed diagnosis. The etiopathogenicity of squamous cell carcinoma of the colorectum is discussed. Surgical resection of the lesion seems to be the treatment of choice. Chemotherapy also helps in improvement of the prognosis. PMID:21118539

    There have been some reports of coincidental presentation of breast carcinoma and phyllodes tumor in the same breast. Most of the cases were carcinoma that arose from a phyllodes tumor with a histologically identified transitional area, and they behaved less aggressively than the usually encountered carcinoma. Collision tumors are rare clinical entities in which two histologically distinct tumor types show involvement at the same site. The occurrence of these tumors in the breast is extremely rare. Here, we report a case of 45-year-old woman who had both invasive ductal carcinoma as the finding of inflammatory carcinoma and a malignant phyllodes tumor in the same breast. There was no evidence of a transitional area between the phyllodes tumor and the invasive ductal carcinoma. To our knowledge, this is the first report of a collision tumor of inflammatory breast carcinoma coincident with a malignant phyllodes tumor in same breast.

    Primary adenocarcinoma of the seminal vesicles is an extremely rare neoplasm. Because prompt diagnosis and treatment are associated with improved long-term survival, accurate recognition of this neoplasm is important, particularly when evaluating limited biopsy material. Immunohistochemistry can be used to rule out neoplasms that commonly invade the seminal vesicles, such as prostatic adenocarcinoma. Previous reports have shown that seminal vesicle adenocarcinoma (SVCA) is negative for prostate-specific antigen (PSA) and prostate-specific acid phosphatase (PAP); however, little else is known of its immunophenotype. Consequently, we evaluated the utility of cancer antigen 125 (CA-125) and cytokeratin (CK) subsets 7 and 20 for distinguishing SVCA from other neoplasms that enter the differential diagnosis. Four cases of SVCA-three cases of bladder adenocarcinoma and a rare case of adenocarcinoma arising in a mullerian duct cyst-were immunostained for CA-125, CK7, and CK20. Three of four cases of SVCA were CA-125 positive and CK7 positive. All four cases were CK20 negative. All bladder adenocarcinomas and the mullerian duct cyst adenocarcinoma were CK7 positive and negative for CA-125 and CK20. In addition, CA-125 immunostaining was performed in neoplasms that commonly invade the seminal vesicles, including prostatic adenocarcinoma (n = 40), bladder transitional cell carcinoma (n = 32), and rectal adenocarcinoma (n = 10), and all were negative for this antigen. In conclusion, the present study has shown that the CK7-positive, CK20-negative, CA-125-positive, PSA/PAP-negative immunophenotype of papillary SVCA is unique and can be used in conjunction with histomorphology to distinguish it from other tumors that enter the differential diagnosis, including prostatic adenocarcinoma (CA-125 negative, PSA/PAP positive), bladder transitional cell carcinoma (CK20 positive, CA-125 negative), rectal adenocarcinoma (CA-125 negative, CK7 negative, CK20 positive), bladder

    The involvement of the female genital tract in transitional cell carcinoma (TCC) has not been fully elucidated in women, although involvement is usually associated with a poor prognosis. The vagina, in particular, is considered to be the most commonly affected gynecological organ, with an incidence of 4% of total TCC cases. The pathogenesis of vaginal TCC is challenging to determine, although it is essential for the adequate management of the tumor and to determine the appropriate treatment. The present study reports a case of bladder TCC and metachronous vaginal TCC. The patient had a history of high risk non muscle invasive bladder cancer treated by BCG and presented with a recurrent carcinoma in situ. A novel cycle of BCG was initiated but the patient had a persistent disease and a palpable mass on bimanual examination. Radical anterior pelvectomy and bilateral pelvic and inguinal lymph node dissection was performed revealing the presence of TCC of the bladder neck and the invasion into the anterior vaginal wall. The differences between local vaginal invasion and the metastatic spread from a primary bladder TCC, the occurrence of a second primary vaginal tumor and the direct implantation of TCC via urine that contains transitional cancer cells were reviewed and analyzed. Finally, a management plan was determined.

    A precursor for invasive ovarian/pelvic high-grade serous carcinoma, termed serous tubal intraepithelial carcinoma (STIC), has been identified and characterized through careful analysis of the fallopian tubes in both prophylactic salpingo-oophorectomy specimens obtained from women with either a family history of breast and/or ovarian cancer or germline mutations of BRCA1 and BRCA2 and in cases of pelvic high-grade serous carcinoma. Data on incidental STICs and clinically occult microscopic invasive high-grade serous carcinomas are limited. We analyzed the clinicopathologic features of 22 cases, including 15 pure STICs and 7 STICs associated with microscopic invasive high-grade serous carcinomas, identified incidentally in fallopian tubes removed for nonprophylactic indications. Patient age ranged from 39 to 79 years (mean: 62.7; median: 61), with only 1 patient under the age of 50. No patients were known to carry BRCA1 or BRCA2 mutations. Of the 12 pure STICs for which the location in the fallopian tube could be established, 9 were in the fimbriated portion, 1 was at the junction of the fimbria and infundibulum, and 2 were in the nonfimbriated tube. Of the 7 STICs with associated invasive high-grade serous carcinoma, 3 were located in the fimbriated portion, 2 were at the junction of the fimbria and infundibulum, and 2 were in the nonfimbriated tube. The invasive components were in the fallopian tube in 6 cases, 4 in subepithelial stroma of tubal mucosa, and 2 as an intramucosal (exophytic) luminal lesion without invasion of underlying subepithelial stroma (size range: 1 to 4 mm). The remaining case had a microscopic focus of high-grade serous carcinoma within the ipsilateral ovary (1.3 mm cortical focus) identified only on deeper sections, without an associated invasive component in the fallopian tube. The preferential finding of atypical epithelium with the cytologic features of high-grade serous carcinoma, namely STIC, in the fallopian tubes rather than the

    Introduction Adenoid cystic carcinoma (ACC) is one of the most frequent malignant salivary gland tumors, which commonly affects the minor salivary glands of the mouth and is rare in the nose and paranasal sinuses. In the maxillary sinus, ACC can mimic inflammatory diseases and has a poor prognosis. Objective To report a case of a 50-year-old man with ACC of the maxillary sinus whose clinical findings in the alveolar ridge mimicked an oroantral fistula. Case Report An excisional biopsy was performed and histopathologic analysis revealed ACC. Lung metastases and residual tumor in the maxillary sinus were detected by imaging methods. In view of the poor general health of the patient, no new surgical intervention was performed and he was only treated by radiotherapy and follow-up. Conclusion Although rare in the maxillary sinus, ACC should be included in the differential diagnosis of lesions affecting this site. PMID:25992095

    Prostate cancer is a common cancer in elderly men and it frequently metastasizes to regional lymph nodes and sometimes to bone. Very rarely in some of the cases it also shows involvement of non-regional lymph nodes like supra-diaphragmatic lymph nodes. In our report, we present a 60-year-old male, initially misdiagnosed as Chronic Obstructive Pulmonary Disease (COPD) with cervical lymph node involvement may be due to infective region or inflammatory pathology, which was later found to have prostatic adenocarcinoma metastatic to supraclavicular lymph nodes. Very less case reports are present which have shown similar presentations. So we would like to highlight that prostatic carcinoma can be present in an atypical form also.

    The urachus is a tubular structure that connects the bladder to the allantois in the embryonic development, involuting after the third trimester. The urachus carcinoma is an extremely rare tumor that accounts for <1% of all bladder cancers. We report a case of a 46-year-old woman, with no past medical history, complaining of hematuria with 6-month duration and a physical exam and an abdominal computed topographic scan revealing an exophytic mass of 6.8 cm longer axis that grew depending on the anterior bladder wall, invading the anterior abdominal wall. Cystoscopy detected mucosal erosion. The biopsy showed structures of adenocarcinoma of enteric type. The surgical specimen showed urachus adenocarcinoma of enteric type with stage IVA in the Sheldon system and stage III in the Mayo system. This case has a 3-year follow-up without disease recurrence.

Here, we describe a case of mixed mucinous carcinoma i.e. mucinous carcinoma with infiltrating ductal carcinoma component and showing apocrine differentiation in a 73-year-old man. This uncommon tumour entity has dismal prognosis and treatment depends largely on the tumour type, size, lymph node involvement and hormonal status.

    Carcinoma of the collecting ducts of Bellini and renal medullary carcinoma are rare aggressive neoplasms of putative distal nephron origin. First described in 1949, case reports and review articles constitute a major source of information on collecting duct carcinoma, whereas Davis and colleagues and the pediatric tumor registry have contributed the seminal works on renal medullary carcinoma. Here we present a detailed study of collecting duct carcinoma (n=39) and renal medullary carcinoma (n=13), characterizing these rare neoplasms and analyzing their interrelationship. Both collecting duct carcinoma and renal medullary carcinoma exhibited significant similarities, such as predilection for the right kidney, tumor mass with an epicenter in the renal medulla, and a mean size of 7 cm. Overall, both tumors exhibited a poorly differentiated adenocarcinoma histology with desmoplastic stromal response (100%), inflammatory infiltrate (100%), frequent perinephric extension (collecting duct carcinoma: 97%; renal medullary carcinoma: 83%), lymphovascular invasion (100%), intraluminal mucin (collecting duct carcinoma: 42%; renal medullary carcinoma: 73%), high nuclear grade (97%), overlapping immunoreactivity for Ulex europaeus agglutinin 1 (collecting duct carcinoma: 75%; renal medullary carcinoma:55%), CK7 (collecting duct carcinoma: 44%; renal medullary carcinoma: 71%), and high-molecular weight cytokeratin (collecting duct carcinoma: 26%; renal medullary carcinoma: 29%), and nonimmunoreactivity for Ksp-cadherin. Histologically, collecting duct carcinoma frequently had tubular, tubulopapillary, or irregular glandular architecture, whereas renal medullary carcinoma commonly demonstrated islands of anastomosing tubules and cords forming irregular microcystic spaces. Multiple metastases to the lymph nodes, lung, bone, and liver were observed in both categories at presentation (collecting duct carcinoma: 17%; renal medullary carcinoma: 36%).

    Background: Squamous cell carcinoma is a severe malignant tumor but was rare in the chronic osteomyelitis. The purpose of this study was to present the results from a retrospective study the cases of squamous cell carcinoma arising from chronic osteomyelitis. Material and methods: Between 1974 and 2010, eight cases of squamous cell carcinoma after chronic osteomyelitis were treated. The patients had an average age of 55 years (range 45 to 66 years), with a male predominance (6 men and 2 woman). We analyzed the time up to cancerization, localization and histopathological types of the carcinoma, and types and results of the treatment. Results: The mean delay between the initial injury and the diagnosis of malignant transformation was 28 years (range 8 to 50 years). The carcinoma resulted from tibia osteomyelitis in six cases, femur in one case and ankle in one case. The pathological examination showed two cases of a well-differentiated squamous cell carcinoma with bone invasion and six cases of invasive squamous cell carcinoma. Curative amputation was performed in all patients but one who refused. No recurrence or metastasis occurred during follow-up time. Conclusion: Amputation appears to be an effective treatment method in squamous carcinoma secondary to chronic osteomyelitis. PMID:26617726

    As a prelude to assessing the relationship of chromosome alterations to clinical outcome in ovarian carcinoma, we report on the cytogenetic analysis on short-term cultures from 54 patients. All patients had histopathologically confirmed malignancy, with the majority of cases demonstrating serous ovarian adenocarcinomas. Structural alterations were evident in 52 cases, whereas numeric changes were identified in 13 cases. The most notable numeric abnormalities were loss of the X-chromosome (9/13 total cases) and +7 (3/9 diploid cases). Structural alterations most frequently involved chromosomes 1, 3, 6, 7, 11, and 12. Chromosomal breakpoints were shown to cluster in several chromosomal banding regions, including 1p36, 1p11-q21, 3p23-p10, 7p (especially 7p22), 11p, 11q, 12p13-q12, and 12q24. The frequency of structural alterations involving the following chromosome arms was found to be significantly increased: 1p (p < 0.01), 7p (p < 0.01), 11p (p < 0.01), 11q (p < 0.05), and 12p (p < 0.05). An analysis of the net gain or loss of chromosome segments was also performed, with the most consistent tendency observed being over-representation of 1q and chromosome 7, deletion of 1p, and loss of the X chromosome.

    Spindle cell variant of ameloblastic carcinoma is an extremely rare tumor. Severe dedifferentiated spindle cell variants are diagnostically challenging, particularly in small biopsy specimens. Here, we report a case of spindle cell variant of ameloblastic carcinoma in the mandible of a 69-year-old male patient and review the available literature. The tumor was surgically resected under general anesthesia. Histopathologic diagnosis of spindle cell carcinoma was made on incisional biopsy, and the final diagnosis was confirmed as spindle cell variant of ameloblastic carcinoma. Immunohistochemistry using cytokeratin and CK19 is helpful in determining the origin of spindle cell variant of ameloblastic carcinoma, particularly CK19 indicated that sarcomatoid spindle cells are derived from odontogenic epithelium. A review demonstrated higher mean age of patients compared with that of other types of ameloblastic carcinoma. The rates of mortality and local recurrence were concurrently 30%. No recurrence or metastasis was seen in the 23-month follow-up period in the present case.

    Non-functional parathyroid carcinoma is an exceedingly rare disease with 31 reported cases since 1909. Because of the scarce number of cases of non-functional parathyroid carcinoma, there are no evidence-based recommendations for its optimal treatment. Surgery, including en bloc resection of the carcinoma, ipsilateral thyroid lobe and isthmus together with a neck dissection only in case of lymph node involvement, is the main treatment for non-functioning parathyroid carcinoma. The patient usually has a poorer prognosis because of detection at advanced stages, the relative ineffectiveness of adjuvant treatment modalities and the lack of adequate parameters for clinical follow-up. In this report, we present a case of non-functional parathyroid carcinoma at our institution, and we review the previous literature to discuss the latest advances in the diagnosis and treatment of this rare disease.

    Breast cancers that present with mucin include mucinous carcinoma and carcinoma with signet ring cell differentiation. The former shows extracellular mucin and the latter shows abundant intracellular mucin. Here, we report a case of breast cancer showing both extracellular mucin and extensive signet ring cell differentiation due to abundant intracellular mucin. Unlike mucinous carcinoma, this case had the features of high-grade nuclear pleomorphism, high mitotic index, estrogen receptor negativity, progesterone receptor negativity, human epidermal growth factor receptor-2 positivity, and ductal type with positivity for E-cadherin. In a case with signet ring cell differentiation, differential diagnosis with metastatic signet ring cell carcinoma of the stomach and colon is essential. In this case, the presence of accompanied ductal carcinoma in situ component and mammaglobin and gross cystic disease fluid protein-15 positivity were findings that suggested the breast as the origin.

    Liver cancer is the second leading cause of cancer death worldwide, with hepatocellular carcinoma (HCC) being the most common type of primary malignant liver tumour, with a typically poor prognosis, growing incidence and a well-documented relationship with chronic inflammation factors of the liver tissue. Despite the fact that family medical history has been identified as a risk factor for the development of HCC, its significance in terms of etiopathogenesis and prognosis is not well documented. With a view to contributing to this discussion, we will report the clinical case of two identical twins with HCC, both diagnosed within a short period of time, by providing relevant clinical data, and relating this to other medical literature reports that could contribute to a deeper understanding of this illness.

    Adenosquamous carcinoma of the liver is a rare variant of cholangiocarcinoma. It is known to be a highly aggressive tumor with a poor prognosis, but its pathogenesis remains unclear owing to limited data in the literature. We report a case of 56-year-old woman who presented with a 1-week history of epigastric pain. Magnetic resonance imaging revealed a 6.5-cm ill-defined mass with low signal intensity in the left lobe of the liver, which was suspicious of cholangiocarcinoma. The patient underwent left hemihepatectomy. Microscopically, the tumor consisted of malignant glandular and squamous components and staged as pT2aN1. Despite postoperative chemoradiation, the patient had recurrence 8 months after surgery. PMID:28081592

    Adenoid cystic carcinoma (ACC) of the sublingual gland is an extremely rare neoplasm. The clinicopathological characteristics of ACC are slow-growing swelling with or without ulceration, perineural spread, local recurrence, and distant metastasis. This report describes a 58-year-old male who had a slowly growing swelling without ulceration on the right side of the mouth floor that had been present for 1 month. In a radiological examination, the mass showed multilocular cystic features and no bony or tongue muscle invasion. No enlarged cervical lymph nodes were detected. Excisional biopsy and histological analysis showed that the lesion was ACC. In addition to reporting a rare case of ACC, this report also discusses the differential diagnosis and treatment of ACC with a review of the relevant literature. PMID:28035309

    Minor salivary gland neoplasms of the buccal mucosa are relatively uncommon. Adenoid cystic carcinoma (ACC), a well-defined entity, occurs most of the times in the parotid, submandibular glands and palate, as far as the intraoral site is concerned. Adenoid cystic carcinoma tends to have an indolent, extended clinical course with wide local infiltration and late distant metastases. We are presenting a case of an adenoid cystic carcinoma of the buccal mucosa in a 48-year-old female patient. PMID:24783155

    Mixed endometrial carcinoma refers to a tumor that is comprised of two or more distinct histotypes. We studied 18 mixed-type endometrial carcinomas - 11 mixed serous and low-grade endometrioid carcinomas (SC/EC), 5 mixed clear cell and low-grade endometrioid carcinomas (CCC/EC), and 2 mixed clear cell and serous carcinoma (CCC/SC), using targeted next generation sequencing and immunohistochemistry to compare the molecular profiles of the different histotypes present in each case. In 16 of 18 cases there was molecular evidence that both components shared a clonal origin. Eight cases (6 EC/SC, 1 EC/CCC and 1 SC/CCC) showed a serous carcinoma molecular profile that was the same in both components. Five cases (3 CCC/EC and 2 SC/EC) showed a shared endometrioid molecular profile and identical mismatch repair protein (MMR) deficiency in both components. A single SC/EC case harbored the same POLE exonuclease domain mutation in both components. One SC/CCC and one EC/CCC case showed both shared and unique molecular features in the two histotype components, suggesting early molecular divergence from a common clonal origin. In two cases, there were no shared molecular features and these appear to be biologically unrelated synchronous tumors. Overall, these results show that the different histologic components in mixed endometrial carcinomas typically share the same molecular aberrations. Mixed endometrial carcinomas most commonly occur through morphological mimicry, whereby tumors with serous-type molecular profile show morphological features of endometrioid or clear cell carcinoma, or through underlying deficiency in DNA nucleotide repair, with resulting rapid accrual of mutations and intratumoral phenotypic heterogeneity. Less commonly, mixed endometrial carcinomas are the result of early molecular divergence from a common progenitor clone or are synchronous biologically unrelated tumors (collision tumors).

    Ledderhose disease is disorder of the plantar aponeurosis. This disease is not so common and can be tackled with a surgical or conservative approach. A case of a 73-year-old man came to our attention who had a 26-year history of painless bilateral plantar nodules coalescing into an indurated mass. An ulcerative nodule had been noted in the last 16 months on the right foot, in the absence of trauma, not responsive to conservative treatment, so we decided to perform a biopsy. The histopatologic examination showed squamous cell carcinoma, with warty, well-differentiated, low-grade malignancy. Surgical treatment was suggested, so, in pneumoischemia, we made a surgical incision including the skin lesion. Then we proceeded to sculpture the anterolateral thigh fasciacutaneous flap to obtain adequate soft tissue coverage. The tumor was completely removed. Current reconstructive possibilities comprise a good anatomofunctional recovery even in the case of large demolition requests for the therapy of advanced cases of the disease described in this article. Correlation between Ledderhose disease and the formation of malignant tumors has not been made as yet, but perhaps an element that could unite these pathologies can be researched in the lively cell proliferation that characterizes both. It would be interesting to analyze the biological substrate, as well as the systemic and local levels, in patients where both diseases are manifested.

    We report a case of a 64-year-old woman with anaplastic carcinoma of the pancreas (ACP) with cyst formation and review 60 ACP cases reported in Japan. In 20% of cases, laboratory tests revealed severe anemia (hemoglobin level < 10.0 g/dL) and elevated leucocyte counts (> 12000/mm3), which were likely attributable to rapid tumor growth, intratumoral hemorrhage, and necrosis. Elevated serum CA19-9 levels were observed in 55% of cases. Cyst-like structures were observed on imaging in 47% of cases, and this finding appears to reflect subsequent cystic degeneration in the lesion. Macroscopically, hemorrhagic necrosis was observed in 77% of cases, and cyst formation was observed in 33% of cases. ACP should be considered when diagnosing pancreatic tumors with a cyst-like appearance, especially in the presence of severe anemia, elevated leucocyte counts, or elevated serum CA19-9 levels.

    Ameloblastic Carcinoma (AC) is uncommon malignant epithelial odontogenic tumour of jaw, with characteristic histologic features and behavior. Clinically, it has aggressive, infiltrative growth pattern with a distinct predilection for mandible. It exhibits histologic features of ameloblastoma and gets dedifferentiated overtime to culminate in carcinoma. Majority of the cases arise denovo (primary) and only few cases arise from a pre-existing ameloblastoma (secondary). Spindle-cell differentiation in ameloblastic carcinoma is rare; Salter described it as a separate entity “low-grade spindle cell ameloblastic carcinoma. Here we report a case of 32-year-old female patient who presented with a swelling present for past six months. It was diagnosed as Spindle cell Ameloblastic Carcinoma (SpAC), after the hemimandibulectomy the patient was under regular follow up for 14 months, no sign of recurrence was seen. PMID:28274070

    Background: Carcinoma of the thyroid gland is one of the most commonly encountered endocrine malignancies. Papillary carcinoma is the most common histological type, and its spread is usually lymphatic. About 30–80% patients with papillary carcinoma develop lymphatic metastases. Case Report: We present here the case of a 70-year-old female patient who had undergone total thyroidectomy 10 years previously, with a histological diagnosis of papillary thyroid carcinoma. A neck dissection was performed ten years after the primary operation due to a mass in the parapharyngeal space and hypopharynx. The mass was diagnosed histologically as papillary thyroid cancer metastasis after the operation. Conclusion: Lymphatic and vascular metastases of papillary thyroid carcinoma separately to the parapharyngeal space and hypopharynx have rarely been reported. In our case, both hypopharyngeal and parapharyngeal space involvement were presented, which is a very rare condition. PMID:25207192

    Nasopharyngeal carcinoma (NPC) is rare among people of Indian ethnicity. A short retrospective case review of clinical records of Indian patients diagnosed with nasopharyngeal carcinoma in a period of 5 years was conducted. Their slides were further subjected to EBV encoded RNA (EBER) - In- situ Hybridization (ISH). The histologic subtype was nonkeratinizing carcinoma in all 4 patients. All were Epstein Barr Virus (EBV) positive. We believe that the crucial factor responsible for nasopharyngeal carcinoma is genetics; either a genetic susceptibility among high risk groups or genetic resistance/immunity in low risk groups. Further genetic studies are required to look for somatic or inherited chromosomal mutations among the various risk populations.

    Malignant pleural effusion can be a manifestation of many malignancies. Involvement of pleural fluid by metatstatic thyroid carcinoma, though reported, is relatively rare. We present 5 cases of metastatic thyroid carcinoma involving the pleural fluid. The diagnosis of thyroid carcinoma in pleural fluid can be particularly challenging as thyroid transcription factor -1 (TTF-1) which is a marker for carcinoma of thyroid origin is also positive in lung adenocarcinomas (which are more frequently associated with pleural effusions) and thyroglobulin (TG) can often be negative in poorly differentiated/analplastic thyroid carcinomas. In our experience, PAX8 is a particularly useful marker in making the distinction. The diagnosis of metastatic thyroid carcinoma in pleural fluid can be challenging and knowledge of the clinical context and supporting immunohistochemical stains is essential for making the right diagnosis.

    Adrenocortical carcinomas are relatively rare, but they are considered to be highly aggressive malignant tumors. Sarcomatoid carcinomas represent an even more aggressive type. Bilateral malignant adrenal tumors are extraordinary rare, except for those that represent metastatic spread from a primary neoplasm. Here we report a case of a 69-year-old woman who presented symptoms that raised strong suspicions of adrenal insufficiency. Bilateral adrenal masses, identified in the imaging study, were responsible for the clinical manifestation and surgically resected. Surgical specimens of the bilateral adrenal tumors shared histological features compatible with sarcomatoid carcinoma. It was very difficult to confirm that the sarcomatoid carcinomas were derived from the cortex of the adrenal glands, but careful morphological observation and the panel of antibodies used for immunohistochemistry made the diagnosis possible. This is the first report of sarcomatoid carcinomas involving both adrenal glands. It should be emphasized that sarcomatoid carcinoma can arise bilaterally from even functionally impaired adrenal glands.

    Pregnancy following squamous cell carcinoma of the vulvar is rare. Its rarity is reflected by a paucity of cases reported in the literature. We report two cases of pregnancy following diagnosis and treatment for vulvar squamous cell carcinoma, and review eleven prior reported cases. In successfully treated vulvar cancer subsequent pregnancy is not shown to increase the risk of disease recurrence, and there appears to be no deleterious effects during the antenatal period. It is possible, when considering prior reports, that prior vulvectomy may increase the likelihood of delivery by caesarean section, though modifications in the surgical management of vulvar carcinoma may have decreased this risk.

Bilateral malignant adrenal tumors are extremely rare except for those that represent metastasis from an extra-adrenal organ. Here we report a 53-year-old woman who presented with abdominal pain and weight loss. Abdominal computed tomography revealed bilateral adrenal masses and a mass in her liver. Surgical specimens showed pleomorphic tumor cells with epithelial and spindle cell morphology and immunohistochemical staining was compatible with sarcomatoid carcinoma. Sarcomatoid adrenal carcinoma should be kept in mind during the management of bilateral adrenal masses. PMID:28097033

    2009-03-01

    A distinctive tumor described under the terms Bellini duct carcinoma and low-grade collecting duct carcinoma has been referred to by us and others as tubulocystic carcinoma. This renal cell carcinoma subtype is not recognized in the World Health Organization 2004 classification. Herein, we present a detailed study of 31 cases to further characterize this rare subtype of renal cell carcinoma. The tumor occurred in adults (mean age, 54 years) with a strong male predominance (7:1). Grossly, the tumors ranged from 0.7 to 17 cm, and exhibited a spongy or "bubble wrap" appearance reflecting the microscopic presence of variably sized cystically dilated tubules lined by a single layer of epithelium. The lining varied with a cuboidal, flat, and hobnail cell appearance, and the neoplastic cells had abundant eosinophilic cytoplasm and enlarged nuclei with prominent nucleoli. The cysts were closely spaced with an intervening variably fibrotic stroma. Immunohistochemistry and ultrastructural examination showed features of proximal convoluted tubules (Pax 2 immunoreactivity and short microvilli with brush border organization) and distal nephron (kidney-specific cadherin immunoreactivity and cytoplasmic interdigitation). Gene expression profiling showed that tubulocystic carcinoma displayed a unique molecular signature. Twenty-four tumors were stage pT1, 4 stage pT2, and 3 stage pT3. Disease progression (median follow-up of 56 months) occurred in 3 patients; 1 with local recurrence, and 2 with distant metastasis to bone and liver. In light of the distinctive clinicopathologic features and a low but definite metastatic potential, this unique subtype of renal cell carcinoma deserves formal recognition in the contemporary classification of renal neoplasms.

    Introduction: Adenoid cystic carcinoma (ACC) is an uncommon tumor of the breast, accounting for approximately 0.1% to 1% of all breast cancers. It is characterized by rare lymph node involvement and distant metastasis, and associated with a favorable prognosis with excellent survival, despite its triple-negative status. In the current state of knowledge, results of breast-conserving treatment with postoperative radiotherapy seem to be equivalent to mastectomy alone, with respect to survival for ACC of the breast. Due to its rarity, there is no consensus on optimal treatment for patients with ACC. Otherwise, the role of chemotherapy and hormonal therapy remains controversial. Further clinical studies are required to compare treatment options for ACC. But, a long-term follow-up is very important and mandatory for affected patients, due to the late onset of local relapse and occurrence of distant metastasis. Case report: Here, we report the case of a patient who presented with a palpable breast mass in the left breast that turned out to be an ACC of the breast. PMID:27994304

    Background Mixed fibrolamellar hepatocellular carcinoma (mFL-HCC) is a rare liver tumor defined by the presence of both pure FL-HCC and conventional HCC components, represents up to 25% of cases of FL-HCC, and has been associated with worse prognosis. Recent genomic characterization of pure FL-HCC identified a highly recurrent transcript fusion (DNAJB1:PRKACA) not found in conventional HCC. Patients and Methods We performed exome and transcriptome sequencing of a case of mFL-HCC. A novel BAC-capture approach was developed to identify a 400 kb deletion as the underlying genomic mechanism for a DNAJB1:PRKACA fusion in this case. A sensitive Nanostring Elements assay was used to screen for this transcript fusion in a second case of mFL-HCC, 112 additional HCC samples and 44 adjacent non-tumor liver samples. Results We report the first comprehensive genomic analysis of a case of mFL-HCC. No common HCC-associated mutations were identified. The very low mutation rate of this case, large number of mostly single-copy, long-range copy number variants, and high expression of ERBB2 were more consistent with previous reports of pure FL-HCC than conventional HCC. In particular, the DNAJB1:PRKACA fusion transcript specifically associated with pure FL-HCC was detected at very high expression levels. Subsequent analysis revealed the presence of this fusion in all primary and metastatic samples, including those with mixed or conventional HCC pathology. A second case of mFL-HCC confirmed our finding that the fusion was detectable in conventional components. An expanded screen identified a third case of fusion-positive HCC, which upon review, also had both conventional and fibrolamellar features. This screen confirmed the absence of the fusion in all conventional HCC and adjacent non-tumor liver samples. Conclusion These results indicate that mFL-HCC is similar to pure FL-HCC at the genomic level and the DNAJB1:PRKACA fusion can be used as a diagnostic tool for both pure and m

    Pure mucinous carcinoma of the breast accounts for about 2% of all breast carcinomas and is associated with a favourable prognosis due to its lower nuclear grade and infrequent axillary or hematogenous metastases. Micropapillary variant of mucinous carcinoma breast has recently received attention as a unique form of invasive carcinoma of the breast exhibiting dual differentiation towards mucinous as well as micropapillary. The characteristic features for labeling a tumor as mucinous micropapillary carcinoma are micropapillary pattern, nuclear pleomorphism, hobnail cells and psammoma bodies in addition to the predominant mucinous component. Micropapillary mucinous carcinoma (MUMPC) when compared to pure mucinous carcinoma tends to have a higher nuclear grade, axillary lymph node metastases, lymphovascular invasion and overexpression of Her 2, p53 and Ki-67, thereby displaying an aggressive clinical behaviour. We present a rare case of micropapillary mucinous carcinoma to highlight the fact that this being a unique and rare variant of mucinous carcinoma should be recognized and reported as a separate category by the pathologists owing to its aggressive clinical behaviour and its influence on the nature of therapy.

With squamous cell and transitional cell carcinoma being the most commonly reported urethral malignancies, primary small cell carcinoma (SCC) of the urethra is extremely rare. To date, only 5 cases have been reported in the literature. We present the first case of primary SCC occurring in the bulbar urethra in an 89-year-old male. We discuss the clinical, histological and immunohistochemical features of SCC of the urethra. Furthermore, we summarize the available literature and discuss the possible treatment options for this rare yet aggressive neoplasm.

    Mammary analogue secretory carcinoma (MASC) of the salivary gland is a malignant tumor which bears morphologic, immunohistochemical and molecular features similar to those of mammary secretory carcinoma. The tumor is considered as a low-grade malignancy perhaps slightly more aggressive than acinic cell carcinoma. High-grade transformation with recurrences, regional nodal involvement, metastases, and cancer-related death has been reported in a few cases. We report an unusual case of large MASC of the parotid gland in a young patient without regional lymph node involvement. To the best of our knowledge till date such a large MASC of the salivary gland has not been reported in the English literature.

    We describe 3 cases of cats that were presented with a sudden onset of monoparesis as a result of arterial thromboembolism without evidence of cardiovascular disease that were subsequently diagnosed with a primary pulmonary carcinoma. Arterial tumor thromboemboli due to pulmonary carcinoma should be considered as a differential diagnosis in cases of lameness or paresis in older cats. We theorize that large tumor emboli may obstruct peripheral arteries leading to acute monoparesis. PMID:25183892

    Primary squamous cell carcinoma of the prostate is a unique and rare clinicopathological entity with fewer than 100 cases reported in the literature. Because of its rarity, the optimal management is not well known. Here, we report a case of primary squamous cell carcinoma of the prostate which was treated with definitive concurrent chemo-radiotherapy with excellent outcome along with a brief review of the literature.

    The aim of the present study was to summarize the clinicopathological and immunohistochemical characteristics of salivary duct carcinoma (SDC) and to evaluate the currently available treatment modalities. Between 2001 and 2011, 11 patients with SDC were diagnosed and treated at the Affiliated Hospital of Stomatology of Nanjing University (Nanjing, Jiangsu, China). The present study retrospectively reviewed the clinicopathological and immunohistochemical data of these 11 patients and the results indicated that the parotid gland was the most commonly affected site, followed by the submandibular gland and the palate. Furthermore, the mean age of onset was 58.8 years and all cases were treated with surgery, with 72.7% receiving post-operative radiation therapy. The range for the follow-up period was 10–89 months and of the 11 patients investigated, only two succumbed to the disease. In addition, the two-year overall survival rate was 75% according to Kaplan-Meier analysis and the mean overall survival time was 72.8 months. In conclusion, the present study determined that the site of the malignancy is the best predictor of survival in patients with the rare salivary malignancy SDC, while age, gender, T stage, N stage, American Joint Committee on Cancer stage, nerve paralysis, post-operative radiation, neck dissection, and protein expression levels of Ki-67, androgen receptor and human epidermal growth factor-2/neu are less influential factors.

    We present a unique case of hepatocellular carcinoma with mucin-producing gland formation. A 53-year-old man with hepatitis B infection presented with weight loss for the past month. Computed tomography demonstrated a 10 × 9.8 cm mass in the right hepatic lobe accompanied by cirrhotic changes in the hepatic parenchyma. Right hepatectomy was performed, and the tumor cut surface showed a poorly-circumscribed, white to pink tumor with numerous nodules and extensive necrosis. Microscopically, the tumor was composed of thick trabeculae and large, irregularly-shaped islands, both of which were filled with pleomorphic eosinophilic hepatoid cells or gland-forming columnar cells with mucin production. Those cells were immunoreactive for cytokeratin 19 in both the trabeculae and the glands. In some tumor cells, limited immunoreactivity for cytokeratin 7, epithelial membrane antigen and carcinoembryonic antigen was noted. The cells forming thick trabeculae were focally positive for hepatocyte paraffin 1 and alpha-fetoprotein. We suggest that this tumor shows bidirectional differentiation into hepatocytes and cholangiocytes, supporting the concepts that human hepatocarcinogenesis can be based on transformation of progenitor cells which can imply divergent differentiation.

    Parathyroid carcinoma is a rare malignancy representing less than 1% of primary hyperparathyroidism cases. Its management is controversial due to lack of large-scale, multicentric studies. We report 8 new cases of parathyroid carcinoma and review the literature. Preoperative diagnosis of carcinoma was possible in 2 (25%) cases. Unclear surgical margins were present in 5 (62.5%) patients; 4 of them underwent subsequent re-exploration and ipsilateral hemithyroidectomy, in one case associated to central lymph node dissection. Recurrent disease is reported in 2 (25%) patients. Considering the high incidence of local recurrence in case of unclear surgical margins, a re-exploration with ipsilateral hemithyroidectomy is indicated in these patients. A neck dissection should be performed only in case of clinically involved lymph nodes, avoiding prophylactic lymphectomy. An aggressive approach is indicated in case of local or distant recurrence to reduce hypercalcemia.

    Background Adnexal masses are not uncommon in patients with breast cancer. Breast cancer and ovarian malignancies are known to be associated. In patients with breast cancer and co-existing pleural effusions, ascites and adnexal masses, the probability of disseminated disease is high. Nevertheless, benign ovarian masses can mimic this clinical picture when they are associated with Meigs' syndrome making the work-up and management of these patients challenging. To our knowledge, there are no similar reports in the literature and therefore we present this case to highlight this entity. Case presentation A 56-year old woman presented with a 4 cm, grade 2, invasive ductal carcinoma of her left breast. Pre-treatment staging investigations showed a 13.5 cm mass in her left ovary, a small amount of ascites and a large right pleural effusion. Serum tumour markers showed a raised CA125 supporting the malignant nature of the ovarian mass. The cytology from the pleural effusion was indeterminate but thoracoscopic biopsy failed to show malignancy. The patient was strongly against mastectomy and she was commenced on neo-adjuvant Letrozole 2.5 mg daily with a view to perform breast conserving surgery. After a good response to the hormone manipulation, the patient had breast conserving surgery, axillary sampling and laparoscopic excision of the ovarian mass which was eventually found to be a benign ovarian fibroma. Conclusion Despite the high probability of disseminated malignancy when an ovarian mass associated with ascites if found in a patient with a breast cancer and pleural effusion, clinicians should be aware about rare benign syndromes, like Meigs', which may mimic a similar picture and mislead the diagnosis and management plan.

    Micropapillary carcinoma is an uncommon variant of urothelial carcinoma with high metastatic potential. The presence of micropapillary carcinoma component in bladder biopsies should alert urologists to its aggressive behaviour. We report the case of a 70-year-old man who presented with macroscopic hematuria lasting 2 weeks. Magnetic resonance imaging revealed a bladder tumour in the dome area extended to perivascular adipose. The transurethral biopsy showed a high-grade micropapillary carcinoma with muscle invasion. Radical cystectomy with lymph node dissection was then performed. The pathological examination revealed a high-grade purely micropapillary carcinoma invading the perivesical adipose. No tumour recurrence or metastasis were reported at the 6-month follow-up.

    Primary candidiasis is rare and often confused with a pre-cancerous lesion, squamous cell carcinoma, or verrucous carcinoma. We report an extremely rare case of squamous cell carcinoma of the vocal cord following primary candidiasis. A 62-year-old man presented to our department reporting a 1-month history of hoarseness. He underwent laryngeal microscopic surgery for a presumptive diagnosis of glottic carcinoma. Histopathologic examination revealed candidiasis and scattered moderate dysplasia. He was treated with itraconazole for 4 weeks, and followed up without any recurrence of candidiasis. However, the 42-month follow-up examination revealed a focal whitish lesion on the right true vocal cord, and a repeat biopsy of this area revealed squamous cell carcinoma without evidence of candidiasis. The patient was treated with radiotherapy and remains well with no signs of tumor recurrence or candidiasis.

    Cutaneous metastasis (carcinoma en cuirasse) is a condition that results from a tumor spreading via lymphatic or vascular embolization, direct implant during surgery or skin involvement by contiguity. Contralateral distant cutaneous breast cancer has never been reported before and hence, the nature and management of such rare cases remains challenging. We aim to present a case of left-sided ‘distant’ cutaneous metastatic invasive duct carcinoma affecting the distal upper extremity (contralateral side) two and half years (disease-free) following treatment for right breast cancer (right mastectomy + chemoradiation). A complete metastatic work-up excluded the presence of any underlying disease. Clinical examination revealed a fungating, irregular ulcer that bled easily on touch involving the left forearm. The ulcer was excised totally and the raw area reconstructed using a split thickness graft. The patient had uneventful postoperative course and now remains disease-free for almost 1 year with no evidence of local recurrence. PMID:26085655

    A peculiar case of bladder carcinoma showing shadow cell differentiation (SCD) in a 72-year-old man is presented. The tumor histologically revealed high grade urothelial carcinoma (UC) and partially contained squamous component with a transition to shadow cell nests, similar to those seen in cutaneous pilomatricoma (PMX). Immunohistochemically, the modes of cell death in the component of SCD were identical to those in PMX. The present case as well as 10 cases of cutaneous PMX showed nuclear expression of beta-catenin, whereas 10 cases of bladder UC with squamous differentiation revealed membranous localization without nuclear expression. These results suggest that nuclear accumulation of beta-catenin may play an important role for SCD in the present case. SCD in extracutaneous tumor is extremely rare and, in the literature, the present case is the second one as for bladder carcinoma.

    Merkel cell carcinoma (MCC) is a rare but very aggressive skin cancer that derives from neuroendocrine cells of the skin. Merkel cell carcinoma morbidity has been continuously increasing for the last few years. Increasing reported incidence of MCC is probably connected with increasing occurrence of this kind of malignancy or with development of histological and immunohistochemical methods of sample examinations which have allowed for more precise diagnosis of skin tumor that might have previously not been accurately recognized. Merkel cell carcinoma develops as nodules early recognized as basocellular carcinoma, squamous cell carcinoma, amelanotic melanoma or skin lymphoma. Merkel cell carcinoma can be morphologically similar to skin metastasis as well as mild changes such as lipoma, cysts, fibroma or vessel changes. Accurate diagnosis is very important because it determines successful management and risk of progression of disease. We describe 5 patients with MCC who underwent surgical excision and then, after estimation of stage of disease, complementary treatment. Our observations prove that every tumor with MCC should be cut out with wide margins and regional lymphadenectomy or sentinel node biopsy is compulsory. After cutting out MCC involved-field radiotherapy is necessary and improves prognosis. Presence of metastases in lymphatic nodes is an indication for complementary chemotherapy. PMID:24596523

    Several enterohepatic Helicobacter spp. (EHS) have been isolated from cats. Despite the reported association between EHS infection and intestinal neoplasia in other species, this association has not been explored in cats. In this study, 55 non-haematopoietic feline intestinal carcinoma cases were histopathologically evaluated. In contrast with prior reports, large intestinal (LI) carcinoma was observed with greater frequency (61 %) relative to small intestinal (SI) carcinoma (35 %). There was a significant association between intestinal location and animal gender. Of males examined, 83 % had LI carcinoma, while no such trend was observed in females. Previously described associations between Siamese breed and intestinal carcinoma could not be definitively confirmed, although the Siamese breed may be predisposed to SI carcinoma location. Of all carcinomas examined in this study, 62 % were classified as adenocarcinoma, although mucinous adenocarcinoma (28 %) and solid carcinoma (11 %) were also identified. Tumours were all moderately or poorly differentiated. When considered by intestinal location and histopathologic classification, LI adenocarcinoma was associated with significantly advanced mean age (13 years) when compared to SI adenocarcinoma and LI mucinous adenocarcinoma (mean, 9 years in both cases), which were also frequently encountered. To determine whether EHS might play a role in feline intestinal neoplasia, Helicobacter genus- and species-specific fluorescence in situ hybridization was performed. Of these carcinoma cases, 56 % were positive for Helicobacter spp. and one or more species-specific assay for Helicobacterbilis, Helicobactercanis or Helicobactermarmotae. The presence of EHS was significantly associated with both LI location (68 %) and mucinous adenocarcinoma (92 %). These findings suggest a role for intestinal bacteria in non-haematopoietic feline intestinal neoplasia.

    The patient was a 44-year-old woman. Mastectomy and sentinel lymph node biopsy had been performed for carcinoma of the left breast approximately 1 year previously. The diagnosis was mucinous carcinoma, T3N0M0, stage ⅡB, ER(+), PgR(+), HER2 score 0, Ki-67 20%. Hormone therapy was administered postoperatively. Four months after the surgery, left axilla lymphadenopathy was observed. Chemotherapy with EC and nab-PTX was started for the postoperative lymph node recurrence. To achieve local control, axillary lymphadenectomy was performed within 1 year postoperatively, and 1 metastatic lesion in the lymph nodes was observed. Hormone therapy was started sequentially, with no subsequent recurrence or metastasis. Mucinous carcinomas are classified as a breast cancer subtype. Mixed type, including breast ductal carcinoma, form a large proportion of mucinous carcinomas and the therapy for breast ductal carcinoma is usually administered in such cases. Conversely, pure type mucinous carcinomas rarely show metastasis and have a good prognosis. In this case, however, metastasis was noted and chemotherapy was not completely effective, and local control was achieved with surgical resection.

    Encapsulated papillary carcinoma (EPC) is a rare low grade carcinoma of the breast with excellent prognosis. This case series focuses on its histopathological and clinical characteristics in our material. Cases of papillary lesions of breast from 1st January 2012 to 30th December 2014 were retrieved from the hospital database. A total of 8 cases were categorized as EPC. Mean age of patients was 66 years. Breast lump with tumour size ranged from 1.5 to 5.0cm, and was the presentation in 75% of cases. Histopathology showed a well circumscribed lesion within a dilated duct comprising of fibro vascular cores lined by neoplastic cells, surrounded by thick fibrous capsule. Immunohistochemistry, for antibody panel p63, ASMA and CK 5/6 were negative for myoepithelial cells. Invasive carcinoma was seen in 3 (37.5%) with associated DCIS in 4 (50%) cases. Meticulous gross, attention to morphology and correct interpretation of immunohistochemistry are imperative for accurate diagnosis.

    A bladder infection of Aspergillus with no evidence of dissemination is rare. We present a case of Aspergillus infection with transitional cell carcinoma of the urinary bladder without any evidence of systemic involvement. A 65-year-old male diabetic whose main complaints were intermittent painful haematuria and nocturia had undergone nephroureterectomy a year and a half back for transitional cell carcinoma of right renal pelvis. Cystoscopy revealed bladder mucosa having fixed broad tumour with encrustation and bleeding on touch at the right vesico-ureteric junction. The histopathologic diagnosis was a high-grade transitional carcinoma with Aspergillus infection. Fungal culture of urine obtained after bladder wash yielded Aspergillus fumigatus.

    Paraneoplastic syndromes (PS) occur less commonly in association with otolaryngologic neoplasms than other carcinomas such as those of lung or breast. Piriform sinus carcinoma with PS is extremely rare. We here report a case of piriform sinus carcinoma accompanied by PS that was initially misdiagnosed as adult onset Still's disease and describe our diagnosis and treatment. One lesson we have drawn from the experience of this misdiagnosis is that PS symptoms may manifest before the primary tumor is evident and complicate the diagnostic process.

    Despite rare, metastatic anal carcinoma confers a poor prognosis. Systemic chemotherapy is the mainstay of treatment for advanced disease while the role of biologics and/or surgical resection of metastatic disease are anecdotal. Compared to isolated liver colorectal or neuroendocrine cancer liver metastases, there is far less experience with resection or nonsurgical local ablative procedures for patients with metastatic anal carcinoma to the liver. We report the case of a 67-year-old woman with metastatic anal carcinoma to the liver who was successfully treated with liver resection and remains free of relapse more than one year later.

    Undifferentiated carcinoma of the gallbladder is a rare cancer type with a poor prognosis. The present study described a case of undifferentiated gallbladder carcinoma of the spindle- and giant-cell type, according to the 2010 World Health Organization classification. Hematoxylin and eosin staining revealed that the tumor consisted of dense interlacing bundles of spindle-shaped cells. No evidence of cartilaginous, osseous or rhabdomyosarcomatous differentiation was observed. Immunohistochemical staining revealed that spindle- and polygonal-shaped cells of the undifferentiated carcinoma were positive for cytokeratin AE1/3, vimentin and vascular endothelial growth factor. Furthermore, numerous spindle-shaped cells were positive for cluster of differentiation (CD)34 and CD31, and certain spindle-shaped cells were positive for Factor VIII. These results suggested classification of the present case as ‘undifferentiated gallbladder carcinoma with endothelial differentiation’. PMID:28101355

    Brain metastases are unusual from urethelial carcinoma of bladder and particularly the occurrence of leptomeningeal metastases is extremely rare, with few cases described in the literature. We present a case of a 45-year-old man with a rare brain metastases as the first metastatic manifestation secondary to urethelial carcinoma of bladder followed by leptomeningeal metastases without any other organ involvement. Eleven months after the diagnosis of high-grade urethelial carcinoma of bladder (T2N0M0), the patient was detected having brain metastases by MRI. FDG PET/CT images for the metastatic evaluation showed no abnormal FDG uptake elsewhere in the body except the brain. Histopathology examination from brain lesion demonstrated the cerebral lesion to be a metastatic urothelial carcinoma. Two months later, the patient was diagnosed to have leptomeningeal metastases by MRI. Our patient's condition gradually worsened, and he died 3 months after the diagnosis of leptomeningeal metastases.

    Cronkhite-Canada syndrome is generally accepted as being a benign disorder. We herein present a 66-year-old-male patient with Cronkhite-Canada syndrome who had a carcinoma of the sigmoid colon along with multiple colonic polyps, which included juvenile-type polyps, adenomas, and hyperplastic polyps. In the world literature, there have been 34 cases of Cronkhite-Canada syndrome associated with colorectal carcinoma among the 280 reported cases of this syndrome. This report thus adds to the growing evidence that Cronkhite-Canada syndrome may be a premalignant condition for colorectal carcinoma. A periodic examination of the colon is therefore advised in order to detect any development of colorectal carcinoma at an early stage.

    There are 3 distinct variants of penile squamous cell carcinoma frequently associated with human papillomavirus (HPV): basaloid, warty-basaloid, and warty carcinomas. Considering the high incidence rates of penile cancer in some countries, a large international study was designed to evaluate the presence of HPV, its genotype distribution, and its association with histologic types of penile cancer. In this international review of >900 cases, we found a group of highly distinct papillary neoplasms composed of basophilic cells resembling urothelial tumors but frequently associated with HPV. Macroscopically, tumors were exophytic or exoendophytic. Microscopically, there was a papillomatous pattern of growth with a central fibrovascular core and small basophilic cells lining the papillae. Positivity for HPV was present in 11 of 12 tumors (92%). Single genotypes found were HPV-16 in 9 tumors and HPV-51 in 1 tumor. Multiple genotypes (HPV-16 and HPV-45) were present in another case. Overexpression of p16 was observed in all cases. Uroplakin-III was negative in all cases. The differential diagnosis was with basaloid, warty-basaloid, warty, and papillary squamous cell carcinoma and with urothelial carcinomas. Local excision (4 cases), circumcision (3 cases), or partial penectomy (5 cases) were preferred treatment choices. Tumor thickness ranged from 1 to 15 mm (average, 7 mm). Two patients with tumors invading 11 and 15 mm into the corpus spongiosum developed inguinal nodal metastasis. Of 11 patients followed up (median 48 mo), 7 were alive with no evidence of metastatic disease, 3 died from causes other than penile cancer, and another died postoperatively. This morphologically distinct tumor probably represents a papillary variant of basaloid carcinomas (papillary-basaloid carcinomas). Unlike typical basaloid carcinomas, the overall prognosis was excellent. However, deeply invasive tumors were associated with regional nodal metastasis indicating a potential for tumor

    Of six children with carcinoma of the colon, none had ulcerative colitis or a family history of carcinoma of the colon or colonic polyposis. In 75 cases traced in the literature, a common early symptom of carcinoma of the colon in children is acute, crampy abdominal pain. At laparotomy for suspected appendictis, the possibility of the acute pain being due to carcinoma of the colon should be borne in mind. Otherwise the symptoms of carcinoma of the colon in children do not differ substantially from those in adults. The prognosis is unfavorable; in only 2.5% of the cases on record did the children survive 5 yr after the operation.

    A 6 8-year-old man was admitted to our hospital with lower abdominal pain. Lower gastrointestinal endoscopy showed type 2 advanced cancer in the ascending colon. Histopathological examination after endoscopical biopsy revealed both moderately differentiated adenocarcinoma and well-differentiated squamous carcinoma. Subsequently, right hemicolectomy was performed. The tumor was 55 × 40 mm in size and was diagnosed as an adenosquamous carcinoma A, type 2, pSS, pN0, sH0, sP0, sM0, fStageII. Adenosquamous carcinoma is extremely rare, represents about 0.1% of all colorectal cancer, and usually has a poor prognosis. Thirty-one months after surgery, the patient is still in good health and displays no signs of recurrence.

    Most penile cancers are squamous cell carcinomas, but there are several subtypes with different clinicopathologic, viral, and outcome features. We are presenting 45 cases of a distinctive morphological variant of penile squamous cell carcinoma composed of mixed features of warty and basaloid carcinomas. This tumor was earlier recognized in a recent viral study and showed a high association with human papillomavirus infection. However, clinicopathologic features are not well known. In this multi-institutional study, patients' mean age was 62 years. Most tumors (64%) invaded multiple anatomical compartments, including glans, coronal sulcus, and, especially, inner foreskin mucosa. Tumor size ranged from 2 to 12 cm (mean 5.5 cm). Three morphological patterns were recognized: (1) the most common, observed in two-thirds of the cases was that of a typical condylomatous tumor on surface and basaloid features in deep infiltrative nests; (2) in 15% of the cases, there were non-papillomatous invasive carcinoma nests with mixed basaloid and warty features; and (3) unusually, predominantly papillomatous. Invasion of penile erectile tissues was frequent, either corpus spongiosum or cavernosum (47% each). Tumors limited to lamina propria were rare. Most tumors were of high grade (89%). Vascular and perineural invasion were found in about one-half and one-quarter of cases, respectively. Associated penile intraepithelial neoplasia was identified in 19 cases and mostly showed basaloid, warty-basaloid, or warty features. Inguinal nodal metastases were found in 11/21 patients with groin dissections. Invasion of corpora cavernosa, high histological grade, and presence of vascular/perineural invasion were more prevalent in metastatic cases. In 21 patients followed, the cancer-specific mortality rate was 33% with a mean survival time of 2.8 years. Warty-basaloid carcinomas are morphologically distinctive human papillomavirus-related penile neoplasms that, such as basaloid carcinomas, are

    The diagnosis of hepatocellular carcinoma in cirrhotic patients has increased, mainly due to early detection using newer imaging techniques. The therapeutic approach depends on the tumor staging and the liver function. Cardiac involvement has a very bad prognosis. We report three males aged 59, 75 and 76 years and two females, aged 64 and 79 years. All had cirrhosis of diverse aetiologies with hepatocellular carcinoma and tumoral invasion of the inferior vena cava and right atrium. Three patients died during hospital stay and two were discharged for conservative management at home. This rare complication has to be considered in cirrhosis.

    Merkel cell carcinoma (MCC) or primary neuroendocrine carcinoma of the skin is a rare neoplasm with aggressive behavior. Primary lymphoepithelioma-like (LEL) carcinoma of the skin is a recently described exceptional tumor, with a relatively good prognosis, and is characterized by a neoplastic epithelial component associated with a dense lymphoid stroma. Rarely, MCC shows a marked lymphocytic host response or can even mimic a LEL carcinoma. We report a new case of MCC mimicking an LEL carcinoma in a 72-year-old male; the diagnosis of MCC was made on the basis of the morphology and immunohistochemical findings. We present through this case an exceptional pattern of MCC which can be misleading, and we insist on differential diagnoses. PMID:22937395

    The aim of this study is to evaluate the association between metabolic disorders and the risk of nasopharyngeal carcinoma, considering different histological subtypes. Between 1992 and 2008, we carried out a multicentre case-control study in Italy. One-hundred and ninety-seven White patients with histologically confirmed nasopharyngeal carcinoma were enrolled as cases. The control group included 592 cancer-free patients, frequency matched by study centre, area of residence, sex, age and period of interview. Odds ratios (OR) and corresponding 95% confidence intervals (CI), for nasopharyngeal carcinoma according to obesity and self-reported history of other metabolic disorders, were calculated through logistic regression models adjusted for matching variables and tobacco smoking and drinking habits. Obesity (OR=1.44; 95% CI: 0.88-2.36), diabetes mellitus (OR=0.91; 95% CI: 0.42-1.98), hypertension (OR=0.79; 95% CI: 0.48-1.32), hypercholesterolaemia (OR=1.41; 95% CI: 0.84-2.35) and metabolic syndrome (i.e. at least three among the four previously cited metabolic disorders; OR=1.11; 95% CI: 0.86-1.43) were not significantly associated with the overall risk of nasopharyngeal carcinoma. However, the associations observed for diabetes mellitus, hypercholesterolaemia and metabolic syndrome were stronger among differentiated nasopharyngeal carcinomas than among undifferentiated ones. In particular, 21.7% of differentiated nasopharyngeal carcinoma cases and 7.8% of controls reported a history of metabolic syndrome (OR=3.37; 95% CI: 1.05-10.81). The results of the study indicated no overall association between metabolic disorders and nasopharyngeal carcinoma. Nonetheless, although the small sample size calls for caution in interpretation, metabolic disorders could increase the risk of differentiated nasopharyngeal carcinoma. This finding further supports a different aetiology of the two histological subtypes.

    The B7 family of immune costimulatory ligands is a group of cell surface proteins that bind to the surface receptors of lymphocytes to fine-tune immune responses. The aberrant expression of these proteins plays a key role in tumor immune evasion. Immunotherapy targeting certain B7 family members, including programmed death ligand 1, has proven quite effective in suppressing tumor growth. However, why such therapy works in only a subgroup of tumors is unclear. We hypothesized that other B7 family members, either alone or in concert with programmed death ligand 1, play a crucial role in tumor pathogenesis and progression. We therefore examined the expression of a newly discovered B7 family member, B7-H4, in 306 cases of ovarian serous carcinoma by immunohistochemistry. We found that 91% (267/293) of the high-grade ovarian serous carcinomas and 69% (9/13) of the low-grade ovarian serous carcinomas expressed B7-H4. The difference between B7-H4 expression in high-grade and low-grade ovarian serous carcinoma was statistically significant (P=.002). Moreover, B7-H4 protein expression in high-grade serous carcinoma was associated with tumor stage (P<.01) but not overall survival or disease-free survival. In conclusion, B7-H4 is frequently expressed in ovarian serous carcinomas, especially high-grade serous carcinomas, and may represent a novel immunotherapeutic target in this cancer.

    Minor salivary gland carcinomas represent a heterogeneous group of tumors with broad variation in clinical appearance and histopathology. Clinical data of patients with small salivary gland malignancies were collected from the medical records. Tissue microarray was constructed to determine the expression pattern of 24 proteins in 35 patients with minor salivary gland carcinomas. The choice of markers was based on involvement in neoangiogenesis, cell-to-cell contact, cell-cycle regulation and carcinogenesis. Protein expression data were correlated to patients' clinical data. Overexpression of patched (p = 0.046) and Smo (p = 0.032) was linked to a better overall survival and Glutathione S-transferase π overexpression was linked to prolonged disease-free survival (p = 0.005). Cox-1 (p = 0.035) and VEGFR2 (p = 0.009) were significantly linked to decreased survival for recurrent disease. Bcl-x (84 %), β-catenin (87 %) and Cox-2 (87 %) were significantly overexpressed in minor salivary gland carcinomas. We have shown that Smo resulted in a better overall survival, whereas Gstπ in improved disease-free survival. VEGFR2 was a prognostic factor for survival after recurrence in patients with minor salivary gland carcinomas. Cyclooxygenase inhibitors and anti-Wnt-1 antibodies might be a potential therapeutic option in an adjuvant setting or for patients with unresectable tumors of the minor salivary glands.

    Hypertrophic pulmonary osteoarthropathy (HPO) is a disabling complication of lung cancer often requiring thoracotomy with vagotomy for control of pain. This condition was confirmed by scintigraphy in six consecutive patients with biopsy-proved lung cancer. All had characteristic bone and joint pain unresponsive to a variety of analgesics. Treatment with indomethacin gave dramatic relief of pain within 72 hours in all six. Consideration should be given to instituting a controlled trial to establish the efficacy of indomethacin for the treatment of HPO. ImagesFigure 1. PMID:3993010

    Primary hepatic neuroendocrine carcinoma (NEC) with concurrent occurrence of hepatocellular carcinoma (HCC) of the liver is very rare. Only 8 cases have been reported in the literature. Concurrent occurrence of HCC and NEC in the liver is classified as combined type or collision type by histological distributional patterns; only 2 cases have been reported. Herein, we report a case of collision type concurrent occurrence of HCC and NEC, in which primary hepatic NEC was in only a small portion of the nodule, which is different from the 2 previously reported cases. A 72-year-old male with chronic hepatitis C was admitted to our hospital for a hepatic mass detected by liver computed tomography (CT) at another clinic. Because the nodule was in hepatic segment 3 and had proper radiologic findings for diagnosis of HCC, including enhancement in the arterial phase and wash-out in the portal and delay phases, the patient was treated with laparoscopic left lateral sectionectomy. The pathology demonstrated that the nodule was 2.5 cm and was moderately differentiated HCC. However, a 3 mm-sized focal neuroendocrine carcinoma was also detected on the capsule of the nodule. The tumor was concluded to be a collision type with HCC and primary hepatic NEC. After the surgery, for follow-up, the patient underwent a liver CT every 3 mo. Five multiple nodules were found in the right hepatic lobe on the follow-up liver CT 6 mo post-operatively. As the features of the nodules in the liver CT and MRI were different from that of HCC, a liver biopsy was performed. Intrahepatic recurrent NEC was proven after the liver biopsy, which showed the same pathologic features with the specimen obtained 6 mo ago. Palliative chemotherapy with a combination of etoposide and cisplatin has been administered for 4 months, showing partial response.

    Carcinoma ex pleomorphic adenoma is a rare tumor arising from the salivary glands that spreads through direct extension, through the lymphatic vessels, and, rarely, hematogenously. When distant metastases have been found, they have been reported mainly in the lung. We present an unusual case of carcinoma ex pleomorphic adenoma of the parotid gland with splenic metastases. The patient presented with a primary carcinoma ex pleomorphic adenoma of the parotid gland and he underwent a total parotidectomy with laterocervical lymphadenectomy ipsilateral and adjuvant radiation therapy to the right parotid area. One year later, the patient showed an ipsilateral supraclavicular lymph node recurrence, treated with surgery and radiation therapy. Two more years later, the patient developed lung and splenic lesions, detected through CT and PET. He underwent splenectomy and pathologic assessment of the specimen showed metastatic carcinoma ex pleomorphic adenoma. To our knowledge, there is no reported case of a carcinoma ex pleomorphic adenoma metastasizing to the spleen. Patients treated for carcinoma ex pleomorphic adenoma should be investigated for distant metastases with a long-term follow-up examination for local and distant metastases and new splenic lesions in these patients should be investigated.

Clinical features and outcome of a patient with primary basal cell carcinoma of the caruncle is described. Review of 8 other cases identified through literature search with the keywords of "basal cell carcinoma" and "caruncle" is presented.A 67-year-old male patient presented with a 12 months' history of a lesion over the caruncular region. Incisional biopsy of the lesion revealed primary basal cell carcinoma of nodular type. MRI of the orbit identified extension of the lesion into the medial orbit. The tumor was excised, and reconstructive surgery was performed. The patient declined subsequent radiotherapy. No recurrence was detected during the follow up of 33 months. The current patient and 8 other patients with primary basal cell carcinoma of the caruncle were reviewed.The main therapeutic approach for primary basal cell carcinoma of the caruncle is complete excision with tumor-free surgical margins. Adjuvant radiotherapy or chemotherapy may be administered when deemed necessary.

    The majority of the metastatic lesions of the adrenal gland normally originate from lung cancer, colon malignant tumor, renal cell carcinoma and melanoma. However, adrenal gland metastasis that metastasize from breast invasive ductal carcinoma are extremely rare. The present study reported a rare case of left adrenal gland metastasis in a 35-year-old female who was diagnosed as breast carcinoma 5 years ago with a mass located on the left adrenal gland, which was detected during a routine examination. The patient was asymptomatic and adrenal gland computed tomography revealed a mass in the left adrenal gland. Definitive preoperative diagnosis failed to be established. Left adrenal gland laparoscopic adrenalectomy was performed and the diagnosis of adrenal gland metastasis of breast invasive ductal carcinoma was confirmed by pathological and immunohistochemical examination. The patient remained in good condition by the time of writing.

    Sebaceous carcinoma (SC) is a highly aggressive malignant adnexal tumor of sebaceous gland origin, accounting for less than 1% of cutaneous. Extraocular sebaceous carcinomas are more aggressive than their ocular counterpart with a predilection for the skin of head and neck, trunk, salivary glands and extremities in decreasing order of frequency. Rippled effect literally means “gradually spreading effect”. In histopathology it describes the unique arrangement of tumor cells in palisading pattern. The tumors in which rippled effect has been reported include adnexal tumors like trichoblastoma, trichomatricoma, trichoblastoma with sebaceous differentiation, trichoblastoma with apocrine differentiation, sebaceoma, basal cell carcinoma, fibrohistiocytic tumors, mesenchymal tumors and melanocytic tumors. We report the first case of extra ocular sebaceous carcinoma with rippled effect with emphasis on the fact that differentiation from other tumors demonstrating rippled effect is important in view of different treatment protocols.

    Papillary lesions of the breast pose diagnostic challenges on aspiration cytology due to overlapping features of benign and malignant entities. Accurate cytologic diagnosis of papillary breast carcinoma cannot usually be made pre-operatively. We present the case of an adult female who underwent fine-needle aspiration (FNA) of a left breast lump. FNA smears were highly cellular showing cohesive clusters, complex papillary fragments and few singly dispersed intact cells. The tumor cells had hyperchromatic nuclei, prominent nucleoli and mild nuclear pleomorphism. A cytologic impression of papillary lesion, possibly malignant (in view of high cellularity, complex papillae and single intact cells) was rendered. The lesion proved to be a papillary carcinoma with microscopic foci of stromal invasion on histologic examination. Papillary carcinoma, an uncommon subtype of breast carcinoma, should be considered while evaluating a papillary lesion with complex branching papillae containing delicate fibrovascular cores and singly lying intact atypical cells.

    Arsenic is commonly known to be associated with squamous cell carcinoma. Among the lesser known associations is basal cell carcinoma and even rarer is its effect on blood vessels causing peripheral vascular disease. Here we present a case of a 55 yr old man with ulceroproliferative lesions on scalp and forehead along with several hyperpigmented patches on trunk and extremities. He had symptoms suggestive of Raynaud's phenomenon that eventually led to digital gangrene. FNAC was done which was suggestive of basal cell carcinoma. On further enquiry, he was found to reside in an arsenic endemic zone and was investigated for blood arsenic level which was elevated. Punch biopsy from different lesions from body confirmed nodular basal cell carcinoma. Presently the patient has stopped drinking water from the local tubewell. On follow-up he shows improvement of Raynaud's phenomenon and skin lesions.

    Thyroglossal duct cyst (TGDC) carcinomas are rarely encountered in the pediatric population. The clinical behavior of these tumors in the pediatric setting is unclear and management is not well defined. Two cases of pediatric thyroglossal duct cyst carcinoma were identified in a review of all thyroglossal duct cysts diagnosed over a ten year period. These two cases were analyzed along with 57 cases of thyroglossal duct cyst carcinoma affecting patients less than 21 years of age compiled from the English literature. Fifty-nine patients (36 females, 23 males) aged 6-20 years (mean 15.0 years) were identified. All presented with an anterior midline neck mass, which was typically mobile and non-tender. The average tumor size was 2.6 cm. Histologically, all tumors were papillary thyroid carcinomas arising in a background of a thyroglossal duct cyst. The tumors exhibited a papillary, follicular, or mixed architecture with classical papillary thyroid carcinoma nuclear features. Soft tissue extension was present in 16 cases. All patients were managed surgically with a Sistrunk procedure, with additional thyroidectomy performed in 29 patients, combined with a lymph node dissection (n = 15), or a Sistrunk and lymph node dissection (n = 5). All patients were stage I at presentation, with 11 showing lymph node metastases. Postoperative radioactive iodine was employed in 20 patients. A papillary carcinoma of the thyroid gland was reported in four of the patients who had concurrent/subsequent thyroidectomies. Recurrences were reported in four patients, with distant metastases in one patient, who died of disease (13 months). Follow up data was available for 45 patients, with an overall mean follow-up of 54.5 months. All patients were alive, with the exception of one who died with disease. TGDC carcinomas in pediatric patients is associated with a good overall prognosis, best managed by Sistrunk procedure alone, with selected lymph node dissection if clinically

    Ductal carcinoma in situ of the breast is very rare in men, representing 0-7% of all male breast cancers. We analysed 15 cases from a retrospective multicentric series of 404 patients (3.7%). It occurs earlier than infiltrating carcinoma (mean age: 55 years), sometimes before 40 years of age. The main symptoms are bloody nipple discharge or retro areolar mass. Modified radical mastectomy constitutes the basic treatment. Lower axillary dissection can eventually be indicated in comedocarcinoma or in tumors larger than 25 mm. The main histologic subgroup is papillary carcinoma, pure or intracystic. As is the case in women, local recurrence, invasive or not, rarely occurs. Theoretically, the cure rate approaches 100%. However, as in all cases of breast cancer in men, an important number of deaths due to secondary cancer or intercurrent disease have been noted. Until now, no clear etiologic factors have been found.

    Thyroid carcinoma-like tumor of the kidney is an extremely rare variant of renal cell carcinoma. Most previously reported cases were incidental finding; and none of them showed papillary thyroid carcinoma (PTC) nuclear features. This study reports the first case of PTC (follicular variant)-like tumor of the kidney in which a female patient presented with hematuria, weight loss, and flank pain. Imaging studies revealed a left renal mass with enlarged hilar lymph nodes. Histologically, the renal tumor had a striking resemblance to follicular variant of PTC. However, no radiological abnormalities were found in the thyroid, mediastinum, or pelvis. Tumor cells were negative for thyroid markers (thyroglobulin and TTF1). According to the authors, this is the first case of PTC (follicular variant)-like tumor of the kidney.

    Lymphoepithelioma-like gastric carcinoma (LELGC) is a rare neoplasm of the stomach that accounts for 1–4% of all gastric cancer cases. It is characterized by the presence of a lymphoid stroma with cells arranged primarily in micro alveolar, thin trabecular and primitive tubular patterns or isolated cells. In the present study, the case of a 50-year-old male patient with LELGC and rectal laterally spreading tumor is presented. Following endoscopic submucosal dissection, a diagnosis of carcinoma was reached and the patient underwent total radical gastrectomy. The postoperative pathological stage was IA T1bN0cM0 according to the Tumor-Node-Metastasis classification of gastric carcinoma, and the patient recovered well. The present case is reported to summarize the endoscopic and pathological characteristics of LELGC. PMID:27073504

    Primary signet-ring cell carcinoma of the urinary bladder is a rare histologic variant of adenocarcinoma. Generally, this neoplasm occurs in middle age and the clinical presentation does not differ from the most frequent transitional cell carcinomas. The prognosis is frequently poor as at diagnosis it is often in an advanced phase. It is essential to distinguish this carcinoma from metastases, as different therapeutic strategies are often necessary. We present 5 cases of primary signet-ring cell carcinoma of the urinary bladder and we used a panel of histochemical and immunohistochemical markers for differential diagnosis from secondary carcinoma in an attempt to elucidate the histogenetic derivation of this neoplasia.

    Small cell carcinoma of the ovary, hypercalcemic type is a very rare aggressive neoplasm of unknown histogenesis, affecting mainly girls and young women. Recently, inactivating mutations in SMARCA4 (BRG1), a member of the switch/sucrose nonfermenting chromatin remodeling complex, has been identified as driver events in most cases. We herein describe 3 cases in 34, 34, and 37-year-old women. Symptoms were mainly abdominal pain and mass. One patient was normocalcemic, and the other 2 had no preoperative serum calcium values available. All patients received radical hysterectomy with salpingo-oophorectomy, lymphadenectomy, and variable multimodality therapy. Two developed abdominal recurrences/metastases and died of disease at 4 and 12 months. One patient was alive without disease 17 months after surgery and radiochemotherapy. Histologic examination showed undifferentiated neoplasms composed of diffuse sheets, nests and cords of noncohesive monomorphic small blue/basaloid cells (classic variant, 1 case), and large undifferentiated/rhabdoid cells with abundant cytoplasm (large cell/rhabdoid variant, 2 case) admixed with minor small cell areas. One case contained rare isolated goblet cells, but true glandular component was absent. All tumors expressed vimentin and variably pancytokeratin and WT1. Nuclear SMARCB1 was intact in all cases (1 case showed small foci with mosaic loss). All tumors showed complete loss of SMARCA4. In conclusion, SMARCA4 immunohistochemistry represents a highly valuable emerging tool in identifying small cell carcinoma of the ovary, hypercalcemic type in routine practice. Distinguishing this aggressive neoplasm from juvenile granulosa cell tumor and other undifferentiated ovarian cancers is mandatory in selecting appropriate chemotherapeutic regimens and would allow better characterization of this entity, for which targeted molecular therapy still remains to be established.

    Sinonasal undifferentiated carcinoma is an extremely rare malignancy of the paranasal sinuses and nasal cavity. It is of unknown etiology, and occurs more commonly in the elderly men, with a routinely shown aggressive behavior and poor prognosis for survival. Radiographically, it looks like severe osteomyelitis. Histopathologic study is essential to confirm diagnosis, and the undifferentiated histologic appearance often necessitates immunohistochemical studies for differentiation from other high-grade neoplasms. We present an 83-year-old man complaining of pain and unilateral swelling on the left side of the face due to a rare malignant tumor of maxillary sinus origin, a sinonasal undifferentiated carcinoma. He underwent hemimaxillectomy and radiotherapy, but refused chemotherapy. Maxillary sinus malignancy may be presented with unspecific symptoms mimicking sinusitis or dental pain. Coming across such symptoms, the physician or dentist must consider malignancies as well, and carry out medical and dental workups. PMID:24910668

    Most malignant tumors originating from the biliary tract are adenocarcinomas, and adenosqamous carcinoma of Klatskin's tumor is a very rare finding. An 83-yr-old man was admitted to our hospital because of jaundice. The abdominal computed tomography and magnetic resonance cholangiopancreatography revealed wall thickening and luminal stenosis of both the intrahepatic duct confluent portion and the common hepatic duct. These findings were compatible with Klatskin's tumor, Bismuth type III. Considering the patient's old age, palliative combined modality therapy was performed. After percutaneous transhepatic biliary drainage, biopsy was performed via percutaneous transhepatic cholangioscopy. The histopathologic findings showed adenosquamous carcinoma. External radiotherapy and intraluminal brachytherapy through the endobiliary Y-type stent were then done. Nine months after the radiotherapy, the laboratory findings and the abdominal computed tomography revealed biliary obstruction and progressive hepatic metastasis. The combined modality therapy of external radiotherapy, intraluminal brachytherapy and stenting assisted him to live a normal life until he finally experienced biliary obstruction. PMID:17939340

    Neuroendocrine carcinoma (NEC) originating from the gastrointestinal hepatobiliary-pancreas is a rare, invasive, and progressive disease, for which the prognosis is extremely poor. The patient was a 72-year-old man referred with complaints of jaundice. He was diagnosed with middle extrahepatic cholangiocarcinoma (cT4N1M0, cStage IV). He underwent a right hepatectomy combined with extrahepatic bile duct and portal vein resection after percutaneous transhepatic portal vein embolization. Microscopic examination showed a large-cell neuroendocrine carcinoma according to the WHO criteria for the clinicopathologic classification of gastroenteropancreatic neuroendocrine tumors. Currently, the patient is receiving combination chemotherapy with cisplatin and etoposide for postoperative multiple liver metastases. Although NEC is difficult to diagnose preoperatively, it should be considered an uncommon alternative diagnosis. PMID:27570432

    Primary small-cell carcinoma arising from the bladder (SmCCB) is uncommon. It differs from urothelial carcinoma (UC), the most common type of bladder cancer, with respect to its cell of origin, biology, and prognosis. Biologically, prostatic SmCCB is much more aggressive than UC, and the prognosis for cases with distant metastasis is especially poor. We report here a case of primary SmCCB (cT3bN1M0) treated with radical cystectomy. PMID:27920687

    Signet-ring cell carcinoma (SRCC) can arise from virtually all organs. However, primary SRCC of the breast is very rare. Until 2003, SRCC was placed under ‘mucin-producing carcinomas’ and separated from other carcinomas by the World Health Organization (WHO). To date, only a few cases have been reported. A case of a 46-year-old woman with primary SRCC of the breast is presented in this report. The patient underwent a right modified radical mastectomy with axillary lymph node dissection. Characteristic features and differential diagnosis of this tumor are discussed in the light of pertinent literature. PMID:23938020

    Verrucous carcinoma of the vulva is a rare lesion (1). Affecting essentially postmenopausal women, this lesion is a distinct and particular entity in vulval carcinoma classification and its scalability is uncertain and unpredictable. Here, we present a case concerning a 48-year-old patient, without follow-up after a condyloma acuminate of the vulva (large left lip). The origin of this case will be discussed in this article. The treatment decided was only surgical. A review of literature shows the rarity of this lesion of the female genital tract. PMID:26904547

    Gastric cancer is one of the main causes of death in the world. In Venezuela, gastric tumors represent 37% of all malignant tumors of the digestive system, but only 1,6% to 3,1% of these cases are lymphoepithelioma-like carcinoma. Synchronous neoplastic lesions are also rare. The clinical case presented herein, a man with two synchronous tumor lesions, is the first of its kind in this country. Despite their incipient aspect, the histologic study reported two malignant tumors of epithelial origin: well-differentiated adenocarcinoma and lymphoepithelioma-like carcinoma.

  15. Nasopharyngeal carcinoma presenting with rapidly progressive severe visual disturbance: a case report

    PubMed Central

    2014-01-01

    Introduction Nasopharyngeal carcinoma is one of the most difficult tumors to diagnose correctly at the initial phase because of the occasional lack of nasal symptoms. The perineural spread of the trigeminal nerve is one of the most common and important routes in the intracranial paracavernous extension of nasopharyngeal carcinoma, but visual loss is very rare. Case presentation We report the case of a 54-year-old Japanese man with nasopharyngeal carcinoma, who presented with rapid and severe disturbance of left monocular visual acuity and eye movement with a 10-month history of ipsilateral otitis media and facial pain. Magnetic resonance imaging revealed a lesion in the left fossa of Rosenmüller, pterygopalatine fossa, sphenoid and ethmoid sinus, and the left cavernous sinus extending to the orbital apex through the superior orbital fissure. The histopathological diagnosis was nonkeratinizing undifferentiated nasopharyngeal carcinoma. Epstein–Barr virus was detected by in situ hybridization. Although focal radiotherapy induced remarkable tumor shrinkage and relieved ocular motor disturbance and facial pain, his visual acuity did not improve. Conclusion The awareness of cranial nerves in addition to intracranial and orbital apex involvement, as in this case, is important for appropriate diagnosis and treatment planning of nasopharyngeal carcinoma.

    Context. Severe hypercalcemia is a life-threatening condition. Atypical parathyroid adenoma and parathyroid carcinomas are uncommon causes which can be difficult to differentiate. Objective. We report a case of a 36-year-old male with very high serum calcium due to a possible atypical parathyroid adenoma versus parathyroid carcinoma. Case Illustration. A serum calcium level of 23.2 mg/dl was noted on admission. He was initially treated with IV hydration, pamidronate, and salmon calcitonin to lower his calcium levels. He also underwent a surgical en bloc resection of parathyroid mass. Pathology showed a mixed picture consistent with possible atypical adenoma versus parathyroid carcinoma. However, due to the possible involvement of the recurrent laryngeal nerve, parathyroid carcinoma was more likely. Also after operation the patient developed hungry bones syndrome and his calcium was replaced vigorously. He continues to be on calcium, vitamin D, and calcitriol supplementation. Results. A review of the literature was conducted to identify previous studies pertaining to parathyroid adenomas and parathyroid cancer. Conclusion. We thereby conclude that hypercalcemia requires very careful monitoring especially after operation. Also it can be very difficult to distinguish between atypical parathyroid adenomas and parathyroid carcinomas as in our case and no clear cut guidelines yet exist to differentiate the two based on histology.

    Carcinoma ex pleomorphic adenoma (CXPA) is a rare tumour, with different prevalence rates reported among studies. Epidemiological studies of large series of CXPAs in developing countries are scarce. The aim of the present study was to describe Brazilian patients with CXPA; this was a retrospective study of 38 patients. Demographic and clinico-pathological features were evaluated. No preferential gender was found, and the mean age at diagnosis was 57.6 years. The most commonly involved site was the parotid, followed by the submandibular and the minor salivary glands. A prevalence of clinical stages III and IV was observed at diagnosis. The most common histological subtypes were salivary duct carcinoma, adenocarcinoma not otherwise specified, myoepithelial carcinoma, and epithelial-myoepithelial carcinoma. Moreover, by invasive phase, most were frankly invasive carcinoma. Recurrence was observed in seven out of 24 patients with outcome information available, and all were invasive cases. All seven patients died of causes related to the disease. The distributions of cases according to age, gender, tumour location, and clinical stage were similar to those reported in the literature. Frankly invasive cases presented a worse prognosis. More information is needed to further our understanding of the clinico-pathological aspects of CXPA.

    Variegate porphyria is an autosomal dominant acute hepatic porphyria characterized by photosensitivity and acute neurovisceral attacks. Hepatocellular carcinoma has been described as a potential complication of variegate porphyria in case reports. We report a case of a 48-year-old woman who was diagnosed with hepatocellular carcinoma following a brief history of right upper quadrant pain which was preceded by a few months of blistering lesions in sun-exposed areas. She was biochemically diagnosed with variegate porphyria, and mutational analysis confirmed the presence of a heterozygous mutation in the protoporphyrinogen oxidase gene. Despite two hepatic resections, she developed pulmonary metastases. She responded remarkably well to Sorafenib and remains in remission 16 months after treatment. A review of the literature revealed that hepatocellular carcinoma in variegate porphyria has been described in at least eight cases. Retrospective and prospective cohort studies have suggested a plausible association between hepatocellular carcinoma and acute hepatic porphyrias. Hepatic porphyrias should be considered in the differential diagnoses of hepatocellular carcinoma of uncertain aetiology. Patients with known hepatic porphyrias may benefit from periodic monitoring for this complication.

    2012-01-01

    Primary small cell carcinoma of the esophagus is a relatively rare malignancy. It is highly progressive and poorly prognostic in untreated conditions. In the western populations, the rate of primary small cell carcinoma in all esophageal cancer types is between 0.05% and 2.4%, while it is endemically increasing up to 7.6% in the eastern populations. Most of the cases are in extensive stage at the time of diagnosis. Surgery is the treatment of choice in limited stages, but treatment must be multimodal in primary small cell carcinoma of the esophagus. A 47-year-old woman was referred to our clinic with gradually increasing severe dry cough and slight difficulty in swallowing for 20 days. Chest X-ray graphy was normal, and computed tomography of the chest showed multiple mediastinal lymph nodes and hepatic metastases. Her endoscopic examination revealed an endoluminal vegetative mass between 20 cm and 23 cm of her esophagus. The case was reported as small cell carcinoma of the esophagus on histopathological examination. The case was assumed inoperable, and chemotherapy and radiotherapy were planned. We presented a rare cause of the cough and primary esophageal small cell carcinoma in this paper. PMID:22461794

    Objective: To evaluate the expression of Von Hippel Lindau (VHL) gene in diagnosed cases of renal cell carcinoma. Methods: This cross sectional study was conducted in department of Pathology, Basic Medical Sciences Institute, JPMC, Karachi, from January 2007 to December 2012. Paraffin embedded blocks of 30 cases of radical nephrectomy specimens diagnosed as renal cell carcinoma including CCRCC 21 (70%) CCPRCC, 3 (10%), PRCC 2 (6.79%), hybrid tumor 4 (13.3%), chromophobe tumor (0%) processed for VHL gene expression on Polymerase Chain Reaction. Results: All the 30 cases previously diagnosed as renal cell carcinoma were processed on PCR, VHL gene mutations were seen in 20 (95.23%) of CCRCC while a single case was negative for VHL mutations. All CCPRCC were negative for VHL mutation. Among the hybrid tumor 03 cases with foci of clear cells show VHL mutation while a single case showing combination of clear cells and chromophobe cells was negative for mutation. Both the cases of PRCC were positive for mutation. Exon 3 mutation at base pair 194 seen in 8 (32%) cases and Exon 2 mutation at base pair 150-159 seen in 17 (68%) cases. None of the cases showed Exon 1 mutation. Conclusion: The present study shows that majority of CCRCC showed VHL mutation including the hybrid tumor with clear cell component in our population.

    Objectives: Ghost cell odontogenic carcinoma is a rare condition characterized by ameloblastic-like islands of epithelial cells with aberrant keratinitation in the form of Ghost cell with varying amounts of dysplastic dentina. Material and Methods: We report a case of a 70 year-old woman with a rapid onset of painful swelling right maxillary tumor. Magnetic resonance showed a huge tumor dependent on the right half of the right hard palate with invasion of the pterygoid process and focally to the second branch of the trigeminal. Radiological stage was T4N0. The patient underwent a right subtotal maxillectomy with clear margins. Adjuvant radiotherapy was given. The patient was free of residual or recurrent disease 12 months after surgery. Results: The tumor was 3,9cm in diameter. It was spongy and whitish gray. Microscopically the tumor was arranged in nets and trabeculae, occasionally forming palisade. Tumoral cells had clear cytoplasm with vesicular nuclei. There was atipia and mitosi with vascular and perineural invasion. The excised tumor was diagnosed as a GCOC. Conclusions: Ghost cell carcinoma is a rare odontogenic carcinoma. Its course is unpredictable, ranging from locally invasive tumors of slow growth to highly aggressive and infiltrative ones. Wide surgical excision with clean margins is the treatment of choice although its combination with postoperative radiation therapy, with or without chemotherapy, remains controversial. Key words:Ameloblastic carcinoma, calcifying odontogenic cyst, Ghost cell carcinoma, keratinizing epithelial odontogenic cyst, maxillary tumor, odontogenic carcinoma. PMID:25674335

    2010-01-01

    Background Infiltrating lobular carcinoma (ILC) is the second most common type of invasive breast cancers and it has been reported to have some unique biologic and epidemiologic characteristics. Methods Clinicopathological features of 95 patients with ILC, their relapse free survival (RFS) and overall survival (OS) were retrospectively investigated and compared with those of 3,621 patients with infiltrating ductal carcinoma-not otherwise specified (IDC-NOS) between January 1984 and December 2005. Results ILC constitutes 2.3% of all invasive breast cancers. There were no difference between the ILC and the IDC-NOS groups regarding age at diagnosis, tumor size, nodal status, and treatment modalities except hormone therapy. The ILC group showed more estrogen receptor expression, less HER-2 expression and higher bilaterality. RFS and OS of the ILC patients were similar to those of the IDC. IDC-NOS metastasized more frequently to the lung and bone, whereas, ILC to the bone and ovary. Conclusions The incidence of ILC was relatively low in Korean breast cancer patients. Comparing to IDC-NOS ILC showed some different features such as higher estrogen receptor expression, less HER-2 expression, higher bilaterality and preferred metastatic sites of bone and ovary. Contralateral cancers and bone and ovary evaluation should be considered when monitoring ILC patients. PMID:20423478

  3. Lobular Carcinoma of the Breast Metastatic to the Spleen and Accessory Spleen: Report of a Case

    2016-01-01

    Despite the fact that accessory spleen (also known as supernumerary spleen, splenunculus, or splenule) can be found in 10–30% of patients undergoing autopsies, metastatic disease occurring in this organ has been barely reported. A case of lobular breast carcinoma metastatic to the spleen and accessory spleen found incidentally at therapeutic splenectomy for severe anemia and thrombocytopenia is described. On microscopic examination both organs revealed severe fibrocongestive changes and extramedullary hematopoiesis with no obvious carcinomatous involvement. Cytokeratin 7, estrogen receptors, and GATA3 immunohistochemistry disclosed the presence of numerous metastatic breast carcinoma cells infiltrating the splenic parenchyma. This case demonstrates that metastatic carcinoma can be encountered, although rarely, in accessory spleens and that cytokeratin stain should be performed in sections of spleens and/or accessory spleens excised from cancer patients in which the presence of malignant epithelial cells is not recognized on routine sections.

    Mucoepidermoid carcinoma is the most common malignant tumor of the salivary gland. The oncocytic variant of mucoepidermoid carcinoma (OMEC) is rare and a small subset shows exclusive oncocytic morphology. Here we report an OMEC case of the parotid gland in a 74-year-old woman with exclusive oncocytes and rare mucocytes. The oncocytes showed diffuse nuclear positivity with p63 immunostaining. The MAML2 translocation was present, supporting the diagnosis of OMEC. Distinguishing OMEC with exclusive oncocytes from oncocytoma and oncocytic carcinoma can be very challenging for pathologists and is critical for proper clinical management. Our experience suggests that appropriate ancillary studies, especially the MAML2 translocation, may provide the essential evidence in difficult cases. Our literature review shows that the presence of mucocytes in an oncocytic neoplasm might be an important morphologic clue of OMEC. PMID:27441073

    Pleomorphic adenoma originally called the mixed tumour is a neoplasm commonly involving major salivary glands. The spectrum of malignancy in pleomorphic adenoma comprises three distinct entities - Carcinoma ex pleomorphic adenoma, carcinosarcoma and benign metastasising pleomorphic adenoma. Carcinoma ex pleomorphic adenoma consists of pleomorphic adenoma with a malignant epithelial component. Occasionally, carcinomas ex pleomorphic adenoma develops metastasis. Here we are reporting here a case of benign pleomorphic adenoma arising in parotid gland which turned into malignancy after four years. The patient developed facial nerve paralysis suggesting malignant transformation. Along the course of the disease, the patient developed regional metastasis to lymph nodes and neck and distant metastasis to liver. This case report emphasises the role of advanced imaging modalities in the early diagnosis of the condition and evaluation of metastasis. The patients with this condition should be treated early for favorable outcome and investigated for distant metastasis.

    Anaplastic transformation of well-differentiated thyroid carcinomas at distant metastatic sites is a rare condition. Most cases described in the literature have occurred in the thyroid or regional lymph nodes. We report a case of anaplastic transformation of the follicular variant of papillary thyroid carcinoma in mandibular metastases. A 76-year-old female presented with a painful and enlarging mandibular mass. She had been treated in the past for the follicular variant of papillary thyroid carcinoma. A palliative hemi-mandibulectomy was performed. Histology revealed a metastatic papillary thyroid carcinoma, follicular variant, with an unusual finding of solid pleomorphic epithelioid and spindle cell areas, consistent with anaplastic transformation.

    2007-02-01

    A 60-year-old woman with primary sclerosing cholangitis (PSC) and high levels of ALP, gamma-GTP, and DUPAN-2 was admitted to our institution for examination. The patient did not have ulcerative colitis or pancreatic intraductal papillary mucinous neoplasm. Imaging studies revealed atypical dilation of bile ducts in the left lobe of the liver. Repeated cytologic examinations of the bile showed atypical cells consistent with adenocarcinoma. The patient underwent extended resection of the left lobe of the liver and was found to have intraductal papillary carcinoma with associated mucin-producing bile duct carcinoma. This carcinoma fills dilated bile duct lumens with mucin. This tumor differs morphologically from typical cholangiocarcinoma, which is usually seen in the late stages of PSC. Just one case of mucin-producing bile duct carcinoma arising from PSC has been reported worldwide. The patient has had no signs of recurrence after 27 months. Patients with mucin-producing bile duct carcinoma, as in the case of its pancreatic counterpart, may have a better prognosis and a higher survival rate than patients with typical cholangiocarcinomas.

    Urethral and penile tissues and their neoplasms are considered anatomically and pathogenetically different. Since we observed urethral dysplastic lesions and some similarities between noninvasive and invasive lesions of the anterior urethra and glans, we designed this study to document epithelial urethral abnormalities in patients with penile squamous cell carcinoma. We examined urethral epithelia from 170 penectomies with invasive squamous cell carcinoma finding a variety of primary epithelial abnormalities in 89 cases (52%) and secondary invasion of penile carcinoma to urethra in 42 cases (25%). Patients' average age was 68 years. Primary tumors measured 4 cm in average diameter and the majority were squamous cell carcinoma of the usual (67%) or verrucous type (15%). Primary epithelial abnormalities found were squamous intraepithelial lesions, metaplasias and microglandular hyperplasias. Urethral squamous intraepithelial lesions of high grade was found in six patients and of low grade in eight cases. Squamous metaplasia, seen in 69 cases, was the most frequent finding. Metaplasias were classified as nonkeratinizing and keratinizing. Nonkeratinizing metaplasias (57 cases) were variegated in morphology: simplex (26 cases), hyperplastic (12 cases), clear cell (11 cases) and spindle (8 cases). Keratinizing metaplasias (12 cases) showed hyperkeratosis and were more frequently associated with verrucous than nonverrucous penile squamous cell carcinoma. Microglandular hyperplasia was present in eight cases. Lichen sclerosus was associated with simplex squamous metaplasia in four cases. Despite the large size of the primary tumors, direct urethral invasion by penile carcinoma was present in only 25% of the cases. The presence of precancerous lesions in urethra of patients with penile carcinoma indicates urethral participation in the pathogenesis of penile cancer. Simplex squamous metaplasia is a common finding probably related to chronic inflammation. Keratinizing and

    Basal cell nevus syndrome is an autosomal dominant disorder characterized by the developmental malformations and its carcinogenic nature. This syndrome shows various symptoms of multiple cutaneous basal cell carcinoma, ketatocystic odontogenic tumors, and inborn abnormalities in the bone and skin. Although basal cell nevus syndrome itself is a rare disorder, we experienced a very rare case in which squamous cell carcinoma of the oral cavity developed, and not cutaneous basal cell carcinoma. Only 4 similar cases have been reported in the English literature. The patient was a 33-year-old woman. She was diagnosed as having squamous cell carcinoma of the hard palate, and basal cell nevus syndrome in our hospital. The patient underwent surgery for squamous cell carcinoma of the hard palate, with postoperative chemoradiothetrapy. Since patients with this syndrome tend to form basal cell carcinoma when exposed to X-ray radiation, we perform radiotherapy with care.

    Basaloid squamous cell carcinoma (BSCC) is an aggressive, high-grade, variant of squamous cell carcinoma (SCC), which is uncommon in the oral cavity but slightly more common in the oropharynx. We present two cases of BSCC, one arising in the floor of the mouth and the other arising on the lateral border of the tongue. The diagnosis of this subtype of SCC is important owing to its particular behavior, with an aggressive course, a high incidence of local recurrence, regional lymph node metastases and mortality rate.

    Pure papillary carcinoma of the breast is a rare tumour affecting elderly postmenopausal women. We report one case in a relatively younger woman presenting with a clinically benign breast lump.The tumour showed extensive apocrine metaplasia. The ease with which abundant material with highly cellular papillary clumps is obtained on fine needle aspirate should be an important consideration favouring papillary carcinoma. The quality and quantity of stroma in papillae rather than the presence or absence of stromal support should also be a guiding criteria for excluding benign papillary lesions.

Twelve cases were selected from 1010 penile carcinomas, part of an international HPV detection study conducted at the Institut Català d'Oncologia, Barcelona, Spain. Immunostaining with p16 was performed on all cases, and HPV-mRNA detection was also performed. En bloc full tumor staining was the utilized criteria for positivity of p16. For HPV-DNA detection, whole-tissue section polymerase chain reaction analysis was performed by SPF10-DEIA-LiPA25 (version 1). The patients' ages ranged from 42 to 92 years (average, 71 y). The tumor was most commonly located in the glans. A characteristic microscopic finding was the presence of a moderate to dense tumor-associated inflammatory cell infiltrate composed of neutrophils, lymphocytes, plasma cells, or eosinophils. Tumors grew in large solid sheets, nests, or had a trabecular pattern. Cells were large and poorly differentiated or anaplastic. Keratinization was minimal or absent. Nuclei were large with prominent nucleoli. Mitoses were numerous. Tumor necrosis was common. Deep invasion of the corpora cavernosa was frequent. p16 and HPV-DNA were positive in all cases, whereas mRNA detection was positive in 9 cases only. The prevalent genotype was HPV16 (9 cases, 75%). Other genotypes were HPVs 58, 33, and 66. Medullary carcinomas of the penis are morphologically distinctive HPV-related high-grade neoplasms affecting older individuals. More studies are necessary to delineate the epidemiological, clinical, and molecular features of this unusual penile neoplasm.

  2. Squamous-cell Carcinoma of the Anus and Anal Canal: An Analysis of 55 Cases

    The analysis is of 55 cases admitted into St. Mark's Hospital from 1922 to 1940. The incidence was 3.35% of all cases of cancer of the rectum, anal canal and anus admitted during this period. Sex distribution—27 males and 28 females. The average age (61.7 years) is higher than that of columnar-cell carcinoma of the rectum (57.4 years). Histology.—The cases have been graded into three grades of malignancy—low grade, medium grade, and high grade. Low grade squamous carcinoma is twice as frequent in men as in women, and generally originates at the anal margin. Medium grade squamous carcinoma is equally distributed between men and women; it may arise at the anus or in the anal canal. High grade squamous carcinoma is much more common in the female sex and is almost entirely limited to the anal canal. Quadrant affected—about one-third of the anal margin growths and one-half of the anal canal growths were situated anteriorly. Differential diagnosis from simple papilloma, simple ulcer, chronic inflammation, tuberculous ulcer, tuberculide, primary chancre, amœbic ulcer, basal-cell carcinoma, columnar-cell carcinoma. Biopsy and grading essential before treatment is decided upon. The results of treatment in the three grades of malignancy are described. The best results were obtained in the early low-grade cases treated by interstitial radium needling. In the medium and high grades only three five-year survivals can be reported and these followed excision of the rectum. The management of the inguinal glands is discussed and the importance of a very close post-operative supervision emphasized. Squamous carcinoma of the anal canal may cause lymphatic metastases in the superior hæmorrhoidal glands; there have been four such cases in this series. Diathermy perineal excision is indicated in these cases. ImagesFig. 1Fig. 2Fig. 3Fig. 5Fig. 6aFig. 6bFig. 7Fig. 1Fig. 2Fig. 3Fig. 4 PMID:19992316

    Metaplastic tumors are rare and represent a heterogeneous group of neoplasms showing dominant areas of non-glandular differentiation. Etiology and pathogenesis of this type of lesion in the breast is uncertain. The most common sources of metastatic squamous cell carcinoma of the breast are lung, esophagus, cervix, and urinary bladder. Squamous cell carcinomas may present clinically with inflammation and average size greater than breast adenocarcinoma. As for imaging studies, mammography shows no typical findings and ultrasound can show a complicated cyst or an inflammatory process, among the differential diagnoses. Therefore, knowing this pathological entity, its clinical course and imaging findings is important to safely treat such a rare and aggressive disease. We herein report a case of metaplastic carcinoma, squamous subtype, diagnosed by core needle biopsy.

    Carcinoma of the bladder metastatic to the breast is only sporadically reported in the literature. To the best of our knowledge, the present report is the first described case of signet ring cell carcinoma of the urinary bladder metastasizing to the breast. The patient was a 43-year-old woman who underwent transurethral partial cystectomy for signet ring cell carcinoma of the urinary bladder and adjuvant chemotherapy with cisplatin and gemcitabine. At 7 months postcystectomy, the patient presented with a solitary nodule in the right breast. Following transdermic core needle puncture biopsy of the lesion and histological examination, the tumor was found to be composed of signet ring cells, which were similar to the cells in the original cystectomy specimen. The patient underwent mastectomy without further chemotherapy and has remained free from metastasis to other organs during 1 year follow-up. PMID:27330778

    This communication reports the second known case of oral phaeohyphomycosis in a patient with squamocellular carcinoma of the lip. The patient, an 82-year-old black woman, a former smoker (for more than 30 years), suffering from an ulcerous vegetative lesion in the middle third of the lower lip for approximately 12 months. The result of the histopathological analysis indicated carcinoma, with well-differentiated keratinized squamous cells and the presence of septate mycelial filaments. In the direct mycological examination, thick and dematiaceous septate mycelial filaments were observed. After the resection surgery, the patient did not need to use an antifungal drug to treat the phaeohyphomycosis, and no follow-up radiotherapy was needed to treat the squamocellular carcinoma. We stress that the presence of the squamocellular lesion of the lip was a possible contributing factor to the infection.

    Clinical symptoms and imaging features of fungal infection are confused with those of atypical nasopharyngeal carcinoma (NPC), and therefore development of a more effective diagnostic method is essential. It is a common knowledge that there is a significant association between Epstein-Barr virus (EBV) and nonkeratinizing NPC. However, fungal infection may be considered to be a vital etiologic agent contributing to the NPC and more evidence is needed to be approved this theory. We report on a rare case of a patient with atypical nasopharyngeal carcinoma (NPC) who suffered from chronic fungal infection and was diagnosed initially as Aspergillosis. Following anti-aspergillus infection therapy, the repeated deep biopsy of the maxillary sinus and MRI confirmed the diagnosis of nasopharyngeal carcinoma (NPC).

    Primary pure squamous cell carcinoma of the duodenum is a very rare type of duodenal neoplasm and is more likely to be presented as a metastatic tumor. The literature offers little information on this subject and includes very few articles and case reports. Laboratory tests, CT and ultrasound examinations, x-rays and immunohistochemical markers assisted us in making this rare diagnosis of primary squamous cell carcinoma of the duodenum in a 47 year old female patient, who presented with weight loss and melena. The 8 cm duodenal tumor with pancreas invasion was resected by a cephalic duodenopancreatectomy. The pathology examination revealed a primary duodenal squamous cell carcinoma moderately differentiated (G2), invasive in the head of the pancreas, with keratinization, stage II B (pT4N0MxL0V0R0). Positive outcome after surgery was highlighted, no recurrence being registered at the 6 month CT scan follow-up.

    Riedel's thyroiditis (RT) is a rare chronic inflammatory disease of the thyroid gland. It is characterized by a fibroinflammatory process that partially destroys the gland and extends into adjacent neck structures. Its clinical manifestation can mask an accompanying thyroid neoplasm and can mimic invasive thyroid carcinoma. Therefore, diagnosis can be difficult prior to surgical removal of the thyroid, and histopathologic examination of the thyroid is necessary for a definite diagnosis. The concurrent presence of RT and other thyroid diseases has been reported. However, to our knowledge, the association of RT with acute suppurative thyroiditis and micropapillary carcinoma has not been reported. We report a rare case of concurrent RT, acute suppurative thyroiditis, and micropapillary carcinoma in a 48-year-old patient.

    Adrenal sarcomatoid carcinoma is a rare adrenal carcinoma. To the best of our knowledge, only 11 cases have been reported since 1987. Adrenal sarcomatoid carcinoma presents a diagnostic challenge due to its atypical symptoms and histological patterns. At the time of diagnosis, a large percentage of patients are already at the metastatic stage and succumb within a few months. The present study reports a case of a 59-year-old man presenting with asthenia and weight loss with adrenal sarcomatoid carcinoma metastatic to the lung. A computed tomography (CT) scan and ultrasonography of the patient's abdomen suggested a large homogeneous mass in the right adrenal gland, and a CT scan of his chest suggested lung metastasis. Right adrenalectomy was performed. Histological examination revealed that the tumor was composed of sarcomatous and carcinomatous differentiation elements. Immunohistochemical examination revealed tumor cell positivity for vimentin and cytokeratin. At the 6-month follow-up the patient exhibited no disease progression and refused further proposed treatment. The patient was alive at the time of writing the current report. The present case report additionally reviews the literature, for the purpose of raising awareness of these rare lesions and assisting in achieving accurate diagnoses and effective treatment.

    Cutaneous reactions to tattoos are well reported and include allergic reactions, infections, and foreign body granuloma or may be a presenting sign of sarcoidosis. There have been very few reported cases of squamous cell carcinoma (SCC) arising in tattoo-treated skin. We report a case of SCC arising within a red-ink tattoo and discuss the potential the role of chronic low-grade inflammation in pathogenesis. This should serve to raise awareness of potential tattoo-related serious adverse effects.

    Tracheobronchial mucoepidermoid carcinomas (MEC) are rare in the pediatric population with literature limited primarily to case reports. Here we present our institutional experience treating MEC in three patients and review the literature of 142 pediatric cases previously published from 1968 to 2013. Although rare, tracheobronchial MEC should be included in the differential diagnosis in a child with recurrent respiratory symptoms. Conservative surgical management is often sufficient to achieve complete resection and good outcomes.

    Antecedentes: el carcinoma neuroendocrino de células pequeñas primario de vejiga es una lesión maligna muy poco frecuente. Caso clínico: paciente masculino de 68 años de edad, que tuvo hematuria macroscópica de 24 horas de evolución. Estudios de imagen mostraron tumoración vesical de 218 cc, que en 20 días alcanzó un volumen de 426 cc. A la tinción con hematoxilina-eosina, histológicamente se apreció: placa sólida infiltrante de bordes irregulares, compuesta por células neoplásicas con claro predominio de núcleo y escaso citoplasma (células pequeñas). A la tinción inmunohistoquímica con cromogranina parecía difusamente positivo en células neoplásicas, en un patrón granular citoplasmático. A la tinción con citoqueratina de alto peso molecular se observó patrón negativo en células neoplásicas con control interno positivo en el urotelio acompañante en espécimen. De igual manera, la tumoración fue positiva para sinaptofisina y CD-56 y negativa para CK-7 y CK-20. El paciente recibió tratamiento a base de radioterapia y quimioterapia. Conclusión: el carcinoma neuroendocrino de células pequeñas primario de vejiga representa de 0.35 a 0.70% de los tumores vesicales primarios. Su diagnóstico se basa en el reconocimiento histológico e inmunohistoquímico. El tratamiento se fundamenta en quimioterapia con cisplatino más cistectomía radical, excepto cuando existe enfermedad metastásica.

    Squamous cell carcinoma is an uncommon histologic type in the urinary bladder. We searched our surgical pathology files and identified 16 cases of squamous cell carcinoma of the urinary bladder. The mean age of patients was 65.4 years (range, 41-77 years). All patients received transurethral resection of the bladder, which demonstrated pure squamous cell carcinomas. Seven patients had clinical evidence of tumor spreading out of the bladder (T4) and did not undergo radical cystectomy. The other 9 patients underwent cystectomy with pelvic lymph node dissection. The cystectomy specimens revealed tumors invading muscularis propria (T2) (n = 4) or perivesical soft tissue (T3) (n = 5). Two patients also had metastasis to lymph nodes. Immunohistochemical studies demonstrated that squamous cell carcinoma cells were positive for epidermal growth factor receptor (n = 16) and for p53 (n = 11). For the 9 patients who received cystectomy, 5 patients were alive at a mean of 92.8 months (range, 59-128 months) and 4 patients died of disease at a mean of 24.0 months (range, 6-58 months). For the 7 patients who did not receive cystectomy, 6 died at a mean of 5.7 months (range, 3-9 months), and no follow-up was available for the remaining patient. In conclusion, squamous cell carcinoma of the bladder frequently presents at an advanced stage and is associated with enhanced expression of EGFR and p53.

    Background The clinical and histological characteristics of salivary gland tumors vary widely, complicating their diagnosis and management, and major differences have been recorded in the distribution of histopathological diagnoses among different countries. Material and Methods This retrospective study reviewed the demographic (age, sex) and clinicopathological (pathology diagnosis and localization) characteristics of cases diagnosed with primary SGC between June 1992 and May 2014 in the Pathology Department of the 12 de Octubre Hospital of Madrid. Diagnoses were recorded according to the 2005 WHO classification. Results The study included 149 SCG patients, aged between 11 and 94 yrs, with mean age at onset of 55.56 yrs and peak incidence in the eighth decade of life. The male:female ratio was 1.01. The parotid gland was the most frequently involved (75.2%). The most frequent carcinoma was mucoepidermoid carcinoma (24.2%), followed by acinic cell carcinoma (15.4%). Conclusions The demographic and histopathological characteristics of patients with salivary gland carcinomas in Spain, reported here for the first time, are broadly similar to those found in other countries.

    Squamous cell carcinomas of the gingiva make up a significant percentage of oral squamous cell carcinomas and are one of the most common causes of death worldwide. Cancers of the gingiva often escape early detection, and hence an early intervention, since their initial signs and symptoms resemble common dental and periodontal infections. This article presents a case of a 29-year-old female patient who presented with a non-healing wound for about 1.5 months post-extraction. The wound was associated with pain and suppuration. A provisional diagnosis of alveolar osteitis was derived at with a differential diagnosis of osteomyelitis and carcinoma of the alveolus. The patient was advised a complete hemogram, orthopantomograph, and intra-oral periapical radiograph of the extraction socket. An incisional biopsy was carried out. Radiographs revealed extensive bone loss, and the biopsy report confirmed the diagnosis of well-differentiated squamous cell carcinoma of the alveolus. Carcinoma of the gingiva often mimics inflammatory lesions and hence is often misdiagnosed. Therefore, any oral lesion should strike a chord of suspicion, and practitioners should base their diagnosis on careful examination, and valid evidence.

    Introduction Xeroderma pigmentosum is a rare autosomal recessive genetic disease. This disease predisposes patients to early-onset skin cancers, particularly squamous cell carcinoma. Here, we report 3 pediatric cases, including 2 deaths. Observation The subjects included 2 boys and 1 girl with skin type VI. All subjects were from consanguineous marriages, and the average age was 7.6 years. The patients all had ulcerative budding tumor lesions in the cephalic region, and the mean disease duration was 18 months. In all 3 cases, the diagnosis of xeroderma pigmentosum was made before the poikilodermal appearance of sun-exposed areas and photophobia. Neurological-type mental retardation was noted in 1 case. Histology confirmed squamous cell carcinoma in all 3 cases. The evolutions were marked by the death of 2 children (cases 1 and 3). In one case, the outcome was favorable following cancer excision and subsequent chemotherapy with adjuvant radiotherapy. Conclusion Squamous cell carcinoma is a serious complication related to xeroderma pigmentosum in Sub-Saharan Africa. Prevention is based on the early diagnosis of xeroderma pigmentosum, black skin photoprotection, screening and early treatment of lesions, and genetic counseling. PMID:27920683

    Introduction Pulmonary mucoepidermoid carcinoma (PMEC) is an uncommon neoplasm of the lung and the main salivary gland-type lung carcinoma. The aims of this study were to review the clinicopathological and immunohistochemical features of PMEC and characterize the genetic events in PMEC. Methods We reviewed the pathology cases in our hospital and found 34 initially diagnosed PMEC cases, 26 of which were confirmed as PMEC after excluding 8 cases of MEC-like pulmonary carcinoma. The clinicopathological characteristics of the 26 PMEC cases and the 8 cases of MEC-like pulmonary carcinoma were retrospectively reviewed. MAML2 rearrangement was detected by fluorescence In Situ Hybridization (FISH). Immunostains of ALK, calponin, collagen IV, CK7, EGFR, HER2, Ki-67, Muc5Ac, p63, p40, and TTF-1 were performed. DNA was extracted from 23 cases of PMEC. Mutation profiling of the EGFR, KRAS, BRAF, ALK, PIK3CA, PDGFRA, and DDR2 genes were carried out using next-generation sequencing (NGS), Sanger sequencing, and quantitative polymerase chain reaction (QPCR) in 9 successfully amplified cases. Results Twenty-six cases of PMEC (18 low-grade, 8 high-grade) included 13 men and 13 women aged 12–79 years. Twenty-two cases had a central/endobronchial growth pattern, and 4 cases had a peribronchial growth pattern. Immunohistochemically, CK7, Muc5Ac, p40, and p63 were positive in all cases (26/26);EGFR was positive in 11 cases (11/26); TTF-1, Calponin, HER2 and ALK were negative in all cases (0/26). MAML2 rearrangement was identified in 12 of 18 PMEC cases. No mutations were detected in any of the 7 genes in the 9 cases that qualified for mutation analysis. Twenty-three PMEC patients had follow-up information with a median interval of 32.6 months. Both the 5- and 10-year overall survival rates (OS) were 72.1%, and a high-grade tumor was an adverse prognostic factor in PMEC. There were 8 cases of MEC-like pulmonary carcinoma aged 36–78 years: 2 cases were located in the bronchus, and 6

    Background The aim of this study is to define an algorithm for the choice of reconstructive method for defects after laryngo-pharyngo-esophagectomy for hypopharyngeal carcinoma. Methods One hundred and forty two cases of hypopharyngeal carcinoma were included and operated on by either partial pharyngectomy, total pharyngectomy or esophagectomy. The reconstructive method was tailored according to the resected segment. Results Pectoralis flap was used in 48 cases, free jejunal flap in 28 cases, augmented colon bypass in 4 cases, gastric pull up in 32 cases and gastric tube in 30 cases. Mean hospital stay was 12 days. Mortality rate was 10.6% and morbidity rate was 31.7%. Total flap failure occurred in 3 cases of free flap and one case of pectoralis flap. There were 23 cases of early fistula. Late stricture occurred in 19 cases, being highest with myocutaneous flap (early fistula 12/50 and late stricture 13/50). Conclusion Free jejunal flap was the flap of choice for reconstruction when the safety margin is still above the clavicle. In cases with added esophagectomy, we recommend gastric tube as a method of choice for reconstruction. PMID:24912532

    INTRODUCTION Mixed large cell neuroendocrine neoplasms of the rectum are rare and aggressive neoplasms. Survival is poor due to the high rate of lymph node metastases and distant metastases at the time of diagnosis. PRESENTATION OF CASE We report a case of a 50-year-old male patient with a mixed large cell neuroendocrine carcinoma with squamous cell carcinoma of the rectum located 8 cm from the anal verge, treated with low anterior resection and total mesorectal excision with free surgical margins. There were lymph nodes metastases but no distant metastases at the time of diagnosis. The patient refused to receive adjuvant chemotherapy and died 6 months later due to liver failure as a result of multiple hepatic metastases. DISCUSSION There are not known predisposing factors for the development of neuroendocrine rectal carcinoma. A neuroendocrine carcinoma of the rectum is a rare tumor with an incidence of less than 0.1% of all colorectal malignancies. The median survival ranges from 5 to 10.4 months in several studies and there are not sufficient data in bibliography about ideal adjuvant therapy after resection of mixed squamous large cell neuroendocrine carcinoma of the rectum. CONCLUSION Low anterior resection and total mesorectal excision with free surgical margins in the presence of lymph nodes metastasis is not a sufficient treatment for rectal neuroendocrine carcinoma. More studies should be done in order to determine the ideal adjuvant treatment of these rare and aggressive tumors. PMID:24240071

    The majority of penile carcinoma is squamous cell carcinoma. Although uncommon in the United States, it represents a larger proportion of cancers in the underdeveloped world. Invasive squamous cell carcinoma may arise from precursor lesions or de novo , and has been associated with lack of circumcision and HPV infection. Early diagnosis is imperative as lymphatic spread is associated with a poor prognosis. Radical surgical treatment is no longer the mainstay, and penile sparing treatments now are often used, including Mohs micrographic surgery. Therapeutic decisions should be made with regard to the size and location of the tumor, as well as the functional desires of the patient. It is critical for the dermatologist to be familiar with the evaluation, grading/staging, and treatment advances of penile squamous cell carcinoma. Herein, we present a review of the literature regarding penile squamous cell carcinoma, as well as a case report of invasive squamous cell carcinoma treated with Mohs micrographic surgery.

    2016-01-01

    Central mucoepidermoid carcinoma (CMC) of the jaw bones is a rare malignant salivary gland tumor of unknown pathogenesis, comprising about 4% of all mucoepidermoid carcinomas (MECs). Most cases are histologically classified as a low-grade tumor and radiographically appear as a well-defined unilocular or multilocular radiolucent lesion. Block resection or wide local excisions are the treatment of choice and patients usually show a good overall prognosis although a long-term follow-up is necessary. This report describes a case of a 28-year-old male with MEC in the posterior region of the mandible and discusses its clinical, radiographic and histopathological findings. Although rare, CMC may be considered a differential diagnosis in cases of proliferative and osteolytic lesions in the oral cavity even when its clinical and/or radiographic findings do not suggest malignancy.

    Primary neuroendocrine carcinoma of the breast is extremely rare. More than 97% of neuroendocrine tumors occur in the gastrointestinal and respiratory tracts. Three cases that have been operated in our clinic and had a diagnosis of primary neuroendocrine carcinoma of the breast were assessed, along with literature data. Histopathological diagnoses were obtained by preoperative core needle biopsy. Breast-conserving surgery was performed in two cases, and modified radical mastectomy in one. In all cases, immunohistochemical studies were positive for neuron-specific enolase and synaptophysin. All patients received adjuvant chemotherapy (CT) and one patient received additional radiotherapy (RT). Recurrence or distant metastasis was not detected during long-term follow-up after surgery.

    Carcinoma ex pleomorphic adenoma (CEPA) is the malignant salivary gland tumor originating from primary (de novo) or recurrent pleomorphic adenoma. Although parotid gland is the most common site, it can also be seen in submandibular gland or minor salivary glands. It can be seen rarely in head and neck region, such as oral cavity, trachea, nasal cavity and lacrimal gland. Although pleomorphic adenoma cases originating from ectopic salivary gland tissue in the neck region are present in the English literature, there is no published pleomorphic adenoma ex carcinoma case. In this case report we presented a CEPA as a 7.5 cm long neck mass in a 72-year-old woman originating from the submandibular region apart from submandibular gland. Difficulties in diagnosis and way to appropriate treatment are discussed with current literature.

    Cancer is one of the leading causes of death world-wide. Apart from the most common etiopathological factors related to cancer, at times very rare causes such as irritant or foreign body induced carcinogenesis is not to be overlooked. To systematically review case reports concerned with the association between dental implants and oral squamous cell carcinoma. A Medline (PubMed), Cochrane database, and Google Scholar search was conducted of dental article published in English related to case reports concerned with oral squamous cell carcinoma occurring around dental implants from 2000 to 2014. Twenty articles were retrieved, which included 20 rare case reports which were systematically reviewed and the results were obtained pertaining to age, clinical symptoms, habits, previous history of cancer, potentially malignant disorders, systemic illness, and local factors. It is imperative to identify promptly persisting inflammation associated with implants. Since malignancy may disguise as periimplantitis, especially in patients who are at risk with contributing prominent predisposing factors. PMID:26538881

    Most endometrial carcinomas contain only 1 Müllerian cell type although the presence of 2 or more cell types within 1 tumor, for example a predominantly low-grade endometrioid carcinoma with a minor component (arbitrarily defined as 30% or less) of high-grade serous and/or clear cell carcinoma, is not uncommon. The current study attempts to evaluate whether the presence of minor serous or clear cell components exerts an adverse effect on the prognosis in stage-I endometrial carcinomas of ''mixed-type.'' The study cases include 22 cases of stage-I endometrioid carcinoma with a minor component of serous carcinoma and 14 cases of endometrioid carcinoma with a minor component of clear cell carcinoma. Minor components were arbitrarily defined as representing anywhere between 5% and 30% of the total tumor. The study cases were compared with 56 cases of histologically pure age-matched and stage-matched endometrioid carcinomas, 6 pure serous carcinomas, and 13 pure clear cell carcinomas. All study and control cases were fully staged. Treatment history and outcome status were obtained and follow-up ranged from 56 to 140 months. Our study suggests that the presence of minor components of serous and clear cell carcinoma, defined as between 5% and 30%, within a mixed-type endometrial carcinoma appears to adversely influence the long-term survival of stage-I tumors, although a larger study is needed to corroborate our findings.

    A 47-year-old man with no history of anal fistula was admitted to our hospital with a complaint of perianal pain. Computed tomography (CT) imaging revealed perianal abscess. Incision and drainage were performed under spinal anesthesia. Ten months after drainage, magnetic resonance imaging revealed anal fistula on the left side of the anus. Subsequently, core-out and seton procedures were performed for ischiorectalis type III anal fistula. Pathological examination of the resected specimen of anal fistula revealed a moderately differentiated adenocarcinoma, leading to the diagnosis of carcinoma associated with anal fistula. No distant metastases or enlarged lymph nodes were observed on positron emission tomography (PET)/CT. We performed abdominoperineal resection with wide resection of ischiorectalis fat tissue. The pathology results were tub2, A, ly0, v0, n0, PM0, DM0, RM0, H0, P0, M0, Stage II. Negative pressure wound therapy was performed for perineum deficiency, after which rapid wound healing was observed. Left inguinal lymph node recurrence was detected 8 months after surgery, for which radiotherapy was administered. Distant metastasis was detected 11 months after surgery. The patient died 21 months after surgery.

    The incidence of oropharyngeal squamous cell carcinomas (SCCs) is increasing and is believed to reflect changing sexual practices in recent decades. For this case-case comparative study, we collected medical and life-style information and data on sexual behavior from 478 patients treated at the head and neck clinic of a tertiary hospital in Brisbane, Australia. Patients were grouped as (i) oropharyngeal SCC (n = 96), (ii) oral cavity, larynx and hypopharynx SCC ("other HNSCCs," n = 96), (iii) other SCCs (n = 141), and (iv) other diagnoses (n = 145). We fitted multivariable logistic regression models to estimate odds ratios (ORs) and 95% confidence intervals (CIs) associated with lifestyle factors and sexual behaviors. Compared to the other three patient groups, the oropharyngeal SCC patients had overall more sexual lifetime partners (kissing, oral sex and sexual intercourse). Oropharyngeal SCC patients were significantly more likely to have ever given oral sex compared to the other three patient groups-93% of oropharyngeal SCC patients, 64% of other HNSCC patients, and 58% of patients with other SCC or other diagnoses. Oropharyngeal SCC patients were significantly more likely to have given oral sex to four or more partners when compared to patients with other HNSCC (odds ratio [OR] 11.9; 95% CI 3.5-40.1), other SCC (OR 16.6; 95% CI 5.3-52.0) or patients with other diagnoses (OR 25.2; 95% CI 7.8-81.7). The very strong associations reported here between oral sex practices and risks of oropharyngeal SCC support the hypothesis that sexually transmitted HPV infections cause some of these cancers.

    A new bleomycin derivative NK631 was administered in five cases of advanced recurrent oral carcinoma. The visible improvement of the tumor was noted in three cases, and in the cases of lower lip carcinoma the tumor completely disappeared, however, there was no effective change in cases of cervical metastases of the floor of the mouth and tongue carcinoma. The peripheral lymphocyte counts and serum proteins disclosed a characteristic decrease, serum proteins decreased in the albumin fraction and slightly increased in alpha 2-globlin fraction. Main side effects of NK 631 were skin exanthema, alopecia, anorexia, pyrexia, fatigue and bleeding from the tumor lesion. Regarding the lung function, the vital capacity did not change, but PaO and PaCO in blood gas analysis were together observed to slightly decrease, and it may be supposed that the influence of NK631 on the lung function cannot be neglected. T-cell ratio, lymphocyte blastoformation following PHA stimulation, PPD and DNCB skin tests, and phagocytosis test of peripheral leucocytes were studied. The immuno-suppressive effect of KK631 was the same or weak as bleomycin.

    Mammary analog secretory carcinoma (MASC) is a rare type of salivary gland tumor named for its morphological and genetic similarity to secretory carcinoma of the breast. These tumors are most often found in the parotid gland but have been described in several other mucosal locations of the head and neck. In this case report, a cutaneous lesion most closely resembling MASC was found in a neck mass of a 64-year-old male patient without evidence of a primary salivary gland or oral tumor. The lesion was excised, and the patient remains disease free to date. This case depicts a rare tumor in the skin most closely mimicking MASC and brings additional awareness to dermatopathologists of this tumor.

    Serous carcinomas most commonly arise within the uterine corpus or ovary/fallopian tube, but there are 2 prior case reports of primary vaginal serous carcinoma. We report 2 examples of high-grade serous carcinoma arising within the urethra or a urethral diverticulum (1 case each). Both neoplasms exhibited the classic morphologic features of high-grade serous carcinoma, and a combination of clinical, radiologic, and pathologic examination excluded other possible sites of primary neoplasm.

    Five cases of a hitherto undescribed breast tumor having histologic features similar to those of the tall cell variant papillary thyroid carcinoma are described. They were composed of columnar mitochondrion-rich to oxyphilic cells arranged in nests, papillae, and follicle-like structures. In addition, the neoplastic cells showed numerous nuclear grooves and, in two cases, nuclear pseudo-inclusions. None of the patients had previous concomitant or subsequent evidence of a thyroid tumor. Immunohistochemistry further excluded a metastasis from the thyroid in the four cases tested, as they were consistently thyroglobulin and thyroid transcription factor 1 negative.

    We present the second reported mammary analog secretory carcinoma (MASC) apparently arising in the thyroid and propose a potential close relationship to ETV6-NTRK3 fusion papillary thyroid carcinoma. The patient, a 36 year old woman, presented with a neck mass of 1 year's duration. Imaging studies showed a tumor involving most of the thyroid with enlarged regional lymph nodes. FNA biopsy yielded a diagnosis of "papillary thyroid carcinoma". Resection revealed a 4.5 cm infiltrative tumor. Final diagnosis was "papillary thyroid carcinoma (PTC) consistent with diffuse sclerosing variant" with positive lymph nodes (2+/4) and margins. Histologic features included mixed microcystic, solid, follicular and papillary architecture, prominent nucleoli, abundant nuclear grooves and rare nuclear pseudo-inclusions. Despite radioactive iodine, radiotherapy and multiagent chemotherapy, the patient progressed over 6 years with local recurrence and additional lymph node involvement finally developing widespread distant metastases. Prompted by the breast carcinoma-like histopathology of a metastasis, immunohistochemical staining was performed and revealed strong expression of GATA3 and mammaglobin with no reactivity for thyroglobulin or TTF-1. The original tumor was then tested and showed the same immunoprofile. RT-PCR confirmed the presence of an ETV6-NTRK3 fusion consistent with a diagnosis of MASC. Our patient's clinical, imaging and morphologic features remarkably mimicked papillary thyroid carcinoma. At the molecular level, the ETV6-NTRK3 fusion in this patient involved exons reported in the rare "papillary thyroid carcinoma" with this translocation. Given the immunophenotype of this case, it is possible that at least some ETV6-NTRK3 fusion positive PTC are actually MASC masquerading as papillary thyroid carcinoma.

    Most nonuterine high-grade serous carcinomas (HGSCs) in women with hereditary breast and ovarian cancer syndrome, due to germline BRCA1/2 mutation, arise in the fimbria of the fallopian tube. However, the site of origin of sporadic HGSC, which is usually widely disseminated at presentation, is not well established. We sought to characterize cases of HGSC discovered incidentally in patients not known to be at high risk, in order to determine the site distribution and possible origin of sporadic HGSC. Incidental microscopic, non-mass-forming cases of serous tubal intraepithelial carcinoma or HGSC in salpingo-oophorectomy specimens in which the tubes and ovaries had been extensively examined were identified. No patients were known or suspected BRCA1/2 mutation carriers. Twenty-one cases were identified (mean age: 57 y). Surgery was for benign disease (n=15), uterine endometrioid adenocarcinoma or atypical hyperplasia (n=3), bladder carcinoma (n=1), or ovarian serous borderline tumor (n=2). In 16 of 21 cases, the lesion was confined to the fallopian tube (unilateral in 14 cases, bilateral in 2). There was serous tubal intraepithelial carcinoma in all cases and invasive HGSC into the underlying lamina propria in 8 of these 16 cases; the invasive focus measured 1.3 cm or less in every case. In the remaining 5 cases, there was fallopian tube mucosal and ovarian involvement; in 2 of these cases, there was also microscopic peritoneal involvement. Sporadic cases of nonuterine HGSC arise in the fallopian tube fimbria in a large majority of cases, providing further evidence for the tubal origin of these neoplasms.

    A 55-year-old man was referred to our hospital for a further examination of a pancreatic cystic tumor with a solid component exhibiting vascularity. A few days later, the patient was admitted with a complaint of sudden severe epigastric pain. Enhanced CT showed the loss of vascularity in the tumor. In particular, contrast-enhanced endoscopic ultrasonography (EUS) clearly demonstrated the disappearance of the blood flow, and a histological examination revealed acinar cell carcinoma with central necrosis. To our knowledge, this is the first case in the literature of acinar cell carcinoma associated with the sudden disappearance of vascularity. In this case, contrast-enhanced harmonic EUS was especially useful for assessing the degree of vascularity.

    Skin cancer remains the most common cancer worldwide, and basal cell carcinoma represents the largest portion of non-melanomatous skin cancers with over 3 million cases diagnosed annually. Locally advanced disease is frequently seen in the elderly posing clinical challenges regarding proper treatment. We report on an 86-year-old female presenting with fatigue, anemia and a large ulcerated skin lesion along the right upper back. A biopsy of the lesion revealed a basosquamous cell carcinoma. She underwent a wide local excision with complex wound reconstruction. Neglected skin cancers in the elderly can present difficult clinical scenarios. There are associated adjuvant therapies that should be considered following resection, such as local radiation therapy and other novel therapies. Newer therapies, such as with vismodegib, may also be considered. A comprehensive, multimodal approach to treatment should be considered in most cases of locally advanced, non-melanoma skin cancers.

    Purpose. Extrapulmonary small cell carcinoma affecting the anal canal is a rare and poorly understood entity which can, in its early stages, masquerade as benign anorectal disease such as hemorrhoids. Methods. We report a case of this rare malignancy which initially presented with hematochezia and anal pain. We also review the literature with regard to previously described cases and management strategies including the role of surgery. Results. Despite aggressive multidisciplinary treatment consisting of chemotherapy and radiation, the disease progressed rapidly with dissemination occurring only three months after completion of treatment. Because of the aggressive nature of this tumor, the treatment options for this almost universally fatal malignancy are often palliative in nature. Conclusion. Chemoradiotherapy is likely the most reasonable approach to extrapulmonary small cell carcinoma of the anal canal given its aggressiveness. PMID:22454644

    Microangiopathic hemolytic anemia (MAHA) can be an uncommon presentation of an underlying malignancy, most often due to signet-ring cell carcinoma (SRCC). Additionally, pure SRCC in a breast primary-tumor comprises <2% of all breast cancers (Shin SY, Park H, Chae SW, Woo HY. Microangiopathic hemolytic anemia as the first manifestation of metastatic signet-ring cell carcinoma of unknown origin: a case report and review of literature. Kor J Lab Med 2011;31:157–61). To the best of our knowledge, the combination of these two entities, pure breast primary SRCC along with MAHA, has not been reported. Here, we present such a rare case. We also evaluate the current literature regarding this and similar disease processes, of which evidence is scarce and further research is needed. PMID:27587305

    The diffuse follicular variant of papillary thyroid carcinoma (DFV-PTC) is a rare malignant thyroid condition. It represents an uncommon variant of papillary carcinoma characterized by a diffuse involvement of thyroid parenchyma, follicular architecture and nuclear features of PTC in absence of a surrounding capsule. Up to date few data have been collected about this entity and, at the best of our knowledge, only 24 cases have been reported in the literature. According to these reports DFV-PTC seems to occur preferentially in young women and shows more aggressive behavior than other papillary thyroid tumors. Herein we present an unusual case of DFV-PTC occurring in an 83 years old woman, involving the entire thyroid gland, without distinct or prevalent thyroid nodules. The tumor was clinically misdiagnosed as obstructive goiter. PMID:28191291

    Objective To demonstrate a unique case report about late and isolated vulvar metastasis of sigmoid adeno-carcinoma with review of the literature. Material-method 57 year old postmenopausal patient with prior sigmoid colon cancer history was admitted with isolated vulvar mass. Immunohistochemistry (IHC) and KRAS gen mutation analysis following surgery were performed to discriminate the metastasis from a vulvar primary malignancy. Further imaging techniques were also performed to exclude additional tumours. Results Immunohistochemistry (IHC) and KRAS gene mutation analysis revealed isolated metastasis of the colonic adeno-carcinoma in the vulva. Conclusion Isolated and late occurring vulvar metastasis of colonic origin is very unusual. Careful evaluation and IHC is useful for such cases. PMID:22949946

    An annular pancreas is an uncommon congenital anomaly that usually presents early in childhood. Malignancy in the setting of an annular pancreas is unusual. We herein report a case of annular pancreas with carcinoma of the papilla of Vater. A 59-year-old man presented with epigastric discomfort and was referred to us after gastroduodenal endoscopy showed a tumor of the papilla of Vater. Preoperative imaging showed the pancreatic parenchyma encircling the descending duodenum and a tumor at the papilla of Vater. A pancreaticoduodenectomy was performed for the annular pancreas and the ampullary tumor. Histological examination confirmed a complete annular pancreas and carcinoma in situ of the papilla of Vater. We also provide a review of the reported cases of an annular pancreas with periampullary neoplasms and discuss the clinical characteristics of this anomaly.

    Tuberculous mastitis is an uncommon disease even in countries where tuberculosis is highly endemic. It typically presents a diagnostic challenge masquerading as carcinoma or other primary disease of the breast. We report the case of a young multiparous Nigerian woman who presented with a tender left breast lump and enlargement of the left axillary lymph nodes for which a provisional diagnosis of carcinoma of the breast was made after clinical and radiological evaluation. The mass was pathologically diagnosed as tuberculous mastitis and anti-tuberculous therapy was instituted although she later absconded. This case shows that TM may present a diagnostic challenge on clinical, radiologic and microbiological investigation. Therefore, a high index of suspicion as well as FNAC and/or histological evaluation of tissue samples remain very important its diagnosis.

    Paraneoplastic glomerulopathy has been described in established cases of the solid tumors of lung, gastrointestinal system, breast, etc., and rarely in patients with Renal Cell Carcinoma (RCC). Studies on secondary glomerular diseases have described a higher incidence of IgA nephropathy in patients with RCC compared to membranous glomerulopathy, which are commonly reported in malignancies of the lung and gastrointestinal tract. Collecting Duct Carcinoma (CDC), a rare high grade adenocarcinoma accounts for <1% of all renal malignancies. It arises from the cells of the collecting ducts of Bellini. We report a case of an elderly male who was diagnosed to have a disseminated CDC during his evaluation for nephrotic syndrome. Renal biopsy was suggestive of a secondary membranous glomerulonephropathy. PMID:28384915

    Nevoid basal cell carcinoma syndrome (NBCCS) is an autosomal dominant disorder, characterized by skeletal anomalies and multiple keratocystic odontogenic tumors of the jaws. The skeletal anomalies of this syndrome are mandibular prognathism, bossing of frontal and parietal bones, high-arched palate, and bifid rib. We report three cases with NBCCS, emphasizing the clinical and radiographic findings, the importance of the early diagnosis of NBCCS, and a preventive multidisciplinary approach in the management of NBCCS.

    A 74-year-old male presented with a large polinodular mass in the neck. Fine needle aspiration cytology (FNAC) showed an undifferentiated large cell carcinoma. Computed tomography (CT) showed a large parotid mass with multiple satelite nodules. The remaining radiological studies were normal. Radical parotidectomy was performed. The tumor was a large cell carcinoma with neuroendocrine features and positive immunostain for neuroendocrine markers. The patient received postoperative radiotherapy and was free of tumor eight months later. Only four cases of large cell neuroendocrine carcinoma (LCNEC) of the salivary gland have been communicated. All of them have involved the parotid gland. This tumor presents in elderly patients as a large infiltrating parotid mass. Fine needle aspiration cytology serves to recognize the carcinoma, but it fails in recognizing the neuroendocrine features of the tumor. The histopathological features of this tumor are the same as in other organs. Chromogranin and synaptophysin are useful immunohistochemical markers. A primary location of the tumor in another organ, specially the lung, should be ruled out. Surgery is the main treatment modality and can be complemented with postoperative radiotherapy. The prognosis seems to be poor. More studies are needed to better define the therapeutical alternatives and prognostic factors of these rare tumors.

    Reports of pregnancy following treatment for vulvar carcinoma are extremely uncommon, as the main problem of subsequent pregnancy is vulvar scarring following radical surgery. We herein report the case of a patient who was diagnosed with stage I squamous cell carcinoma of the vulva at the age of 17 years and was treated with multimodal therapy, including neoadjuvant chemotherapy, wide local excision with bilateral inguinal lymph node dissection and adjuvant radiotherapy. The patient became pregnant spontaneously 9 years after her initial diagnosis and the antenatal course was good, except for mild acute pyelonephritis at 25 weeks of gestation. An elective caesarean section was performed at 38 weeks of gestation due to vulvar scarring following multimodal therapy, particularly radiotherapy. The patient remains alive and well, without signs of recurrence or metastasis 12 years after her diagnosis and treatment. Radical vulvectomy as well as multimodal therapy for vulvar carcinoma, particularly radiotherapy, may cause extensive skin scarring. The presence of vulvar scarring following multimodal therapy for vulvar carcinoma may increase the incidence of caesarean delivery. PMID:27900089

    Three examples of an unusual morphologic variant of papillary thyroid carcinoma (PTC) are reported. The presence of a prominent stromal component resulted in low-power microscopic appearances resembling fibroadenoma, phyllodes tumor, or fibrocystic disease of the breast in two cases. The carcinomatous component grew in the form of anastomosing narrow tubules, clustered glands, solid sheets with or without squamous differentiation, and/or papillae, and exhibited the typical nuclear features of PTC. The abundant stroma had a nodular fasciitis-like quality and was composed of short fascicles of spindle cells separated by varying amounts of mucoid matrix, collagen, and extravasated red blood cells; this was interpreted as an exuberant mesenchymal reaction to the carcinoma. The importance of recognizing this variant of PTC is that, when one encounters a fibroproliferative lesion of the thyroid, a diligent search should be made for papillary carcinoma. This variant also must be distinguished from the vastly more aggressive papillary carcinomas with anaplastic transformation and the so-called carcinosarcomas.

    Dual malignancy is rare in adolescents. Dual malignancy with the second malignancy of thyroid is rare. No association has been reported between dysgerminoma of ovary and carcinoma thyroid in medical literature. Despite a thorough PubMed search (key words — Papillary carcinoma of thyroid, metachronous, dysgerminoma ovary), we were unable to find a previous reported case of metachronous papillary carcinoma of thyroid (PTC) following dysgerminoma of the ovary. After surgery, the patient is being regularly followed up for recurrence/development of new primary. We report this unusual and rare case in a 17-year-old female patient. PMID:27904567

    Metastatic lesions to the clivus have been reported in various cancers including lung cancer, prostate carcinoma, skin melanoma, and hepatocellular carcinoma. There have been only a few reports of breast cancer presenting with isolated clival metastasis. We report a case of 35-year-old lady, who was known case of breast carcinoma presented with diplopia as the only sign of clival metastasis. The etiology was established by magnetic resonance imaging which showed an enhancing lesion in the clivus. The diagnosis of clival metastasis from breast cancer was confirmed by transsphenoidal biopsy. PMID:26044482

    The primary central salivary gland neoplasms of the mandible are rare. They look clinically and radiographically similar to the odontogenic tumours or cysts which are common in the mandible. Myoepithelial carcinoma is a malignant counter part of myoepithelioma. Their diagnosis mainly depends only on thorough histopathological examination. This paper is to report a case of extra salivary tumour, intraosseous myoepithelial carcinoma of right ramus of the mandible. This case report serves to increase awareness and improve the index of diagnosis. PMID:25302285

    Introduction: Squamous cell carcinoma is the most common type of lip and oral cavity cancers. In majority of cases it follows quite common course, and after the surgery it does not produce any harm. This case presents unusual and unexpected growth of upper lip squamous cell carcinoma with severe cosmetic problems, and possible health threats. Case Presentation: A 46-year-old woman noticed on her upper lip “a spot, the size of a wheat grain”, which grew rapidly and reached the size of 0.6 cm during a two-week period. The lesion was red, hard and painful, attached to the skin. It was surgically removed, and primary histopathological finding was follicular keratosis. Recurrent tumor appeared seven days after the operation, with the extreme swelling of the upper lip. The patient was sent to a tertiary hospital, where fungal or bacterial infection was excluded. The change on the patient’s upper lip reached the size of 5 × 2 cm, as soft, reddish nodular tumor. Squamous cell carcinoma was diagnosed after the histopathological audit. With the second surgical intervention the tumor was removed and the defect reconstructed. Conclusions: Prognosis of this type of tumor, apart from its size and differentiation level, depends on infiltration in tumor-surrounding tissue, perineural and perivascular spread. Therefore, it is always necessary to analyze the removed skin especially on margins. PMID:26019891

    Mammary analogue secretory carcinoma (MASC) is a recently described entity in the differential diagnosis of salivary gland tumors. It is notable for a characteristic t(12;15)(p13;q25) translocation that results in a unique fusion protein, ETV6-NTRK3. While several studies have retrospectively identified this translocation in cases previously diagnosed as a different salivary malignancy, there have been relatively few cases where this translocation was identified on initial pathology results, and fewer still in a pediatric population. We present a case of a 15 year old female with a slowly enlarging, painless, left facial mass. MRI demonstrated a cystic mass extending into the deep lobe of the parotid, and she underwent parotidectomy. The tumor cells stained positive for S100 and CK19. ETV6 translocation was present, confirming the diagnosis. Mammary analogue secretory carcinoma is a recently described tumor of the salivary glands, which often masquerades as more common primary salivary gland tumors and cysts. More research is needed to characterize the typical behavior of this neoplasm and the optimal treatment regimen. With identification of its characteristic translocation, mammary analogue secretory carcinoma can be easily differentiated from its more prevalent counterparts, and should therefore remain within the differential of the pathologist and head and neck surgeon.

    To verify the accuracy of the absorbed doses D calculated by a TPS Cadplan for a bronchogenic treatment (in an Alderson-Rando phantom) are chosen ten points with the following D's and localizations. Point 1, posterior position on the left edge with 136.4 Gy. Points: 2, 3 and 4 in the left lung with 104.9, 104.3 and 105.8 Gy, respectively; points 5 and 6 at the mediastinum with 192.4 and 173.5 Gy; points 7, 8 and 9 in the right lung with 105.8, 104.2 and 104.7 Gy, and 10 at posterior position on right edge with 143.7 Gy. IAEA type capsules with TLD 100 powder are placed, planned and irradiated. The evaluation of the absorbed dose is carried out a curve of calibration for the LiF response (nC) {sup vs} {sup DW}, to several cavity theories. The traceability for the DW is obtained with a secondary standard calibrated at the NRC (Canada). The dosimetric properties for the materials considered are determined from the Hounsfield numbers reported by the TPS. The stopping power ratios are calculated for nominal spectrum to 6 MV photons. The percent variations among the planned and determined D in all the cases they are < ± 3%.

    Non-transitional cell carcinomas (non-TCC) of the upper urinary tract as squamous cell carcinoma (SCC), adenocarcinoma, and small cell carcinoma (SmCC) are rare with few case reports in the literature. We retrospectively reviewed our patients who surgically treated for upper tract urothelial carcinoma from 1983 to 2013 for non-TCC pathological cancer characteristics and survival. Among 305 patients, only 5 (1.6%) cases were found: One case of SmCC, another had adenocarcinoma, and 3 SCC cases. None of them had intravesical recurrence and the cancer-specific survival for non-TCC cohort is markedly decreased (log-rank = 0.01) compared to TCC patients. PMID:28216943

    Small cell carcinoma of the rectum is extremely rare. The present study aimed to improve the recognition of computed tomography (CT) and magnetic resonance imaging (MRI) features observed in patients with small cell carcinoma of the rectum. A total of 4 cases of patients with histologically confirmed small cell carcinoma of the rectum were retrospectively reviewed. The imaging features assessed consisted of the thickening of the rectal wall, local tumor invasion, CT density, MRI signal intensity, lesion texture, contrast enhancement characteristics, lymphadenopathy and distant metastasis. All 4 patients displayed ring-like rectal wall thickening and hypodensity in comparison to the gluteus muscles on non-enhanced CT images. MRI demonstrated isointensity on T1-weighted images and hyperintensity on T2-weighted images. Thickening of the left wall of the rectum with patchy low attenuation and the presence of an exophytic mass was observed in 1 patient. Local tumor invasion was observed in the perirectal fat spaces of 4 patients, in the prostate gland and seminal vesicle of 1 patient, and in the left seminal vesicle of 1 patient. Heterogeneous attenuation was exhibited on non-enhanced CT images in 3 lesions, and 1 lesion exhibited heterogeneous intensity on non-enhanced MRI images. All the lesions observed demonstrated strong enhancement following contrast imaging. Lymphadenopathy was observed in 4 patients, liver metastasis in 3 patients, pulmonary metastasis in 2 patients and multiple bone metastases in 1 patient. Overall, small cell carcinoma of the rectum appeared to be more likely to metastasize to the liver, pulmonary, lymph nodes and bone. Distinguishing features of small cell carcinoma of the rectum were noted as a thickening rectal wall, the presence of soft-tissue tumors, local tumor invasion, lymphadenopathy and distant metastases. Pre-operative CT and MRI are required as an aid in selecting the correct treatment plan and for the prognosis assessment of

    Dentigerous cysts are one of the most common odontogenic cysts of the oral cavity. Odontogenic cysts can give rise to a variety of neoplasms. Carcinoma arising in a dentigerous cyst is extremely rare, with a review of literature showing near 30 cases. The present report describes 2 cases of primary intraosseous squamous cell carcinoma originated from a dentigerous cyst. The first one refers to a 57-year old female with a persistent lesion in the left retromolarregion and diagnosed with squamous cell carcinoma originated fromthe incomplete excision of the lower third molar follicle during its surgical extraction. The second case describes the case of an 18-year old male with an impacted upper canine with previous history of infection and swelling of the oral cavity. The histopathological study revealed the malignization of the follicle surrounding the dental crown. These two cases confirmed the importance of the histopathological study of all the tissue samples obtained from surgical procedures. Although the development of a malignant lesion from a dentigerous cyst is rare and its clinical-radiological features are apparently innocuous, this entity should be considered as a differential diagnosis. Key words:Dentigerous cyst, odontogenic cyst, squamous cell carcinoma, primary intraosseous squamous cell carcinoma, odontogenic carcinoma. PMID:26644846

    Renal medullary carcinoma (RMC) is a rare, yet aggressive malignancy of the kidney that is found predominantly in young patients with African descent and sickle cell hemoglobinopathies and most specifically sickle cell trait. Due to its aggressive nature, most cases have metastasis or local invasion at the time of diagnosis. Prognosis is extremely poor with survival less than 1 year after diagnosis. Here we present a case of metastatic RMC in a 29-year-old African female. Despite chemotherapy with cisplatin, gemcitabine, and paclitaxel, and initial shrinkage of the tumor, the patient died 5 months after diagnosis. PMID:28203160

    Summary We present the case of a patient with metastatic parathyroid carcinoma whose hypercalcaemia was medically managed through two pregnancies. The diagnosis was made when the patient presented with chronic knee pain and radiological findings consistent with a brown tumour, at the age of 30. Her corrected calcium and parathyroid hormone (PTH) levels were significantly elevated. Following localisation studies, a right parathyroidectomy was performed with histology revealing parathyroid carcinoma, adherent to thyroid tissue. Aged 33, following biochemical recurrence of disease, the patient underwent a second operation. A subsequent CT and FDG–PET revealed bibasal pulmonary metastases. Aged 35, the patient was referred to our unit for treatment of persistent hypercalcaemia. The focus of treatment at this time was debulking metastatic disease using radiofrequency ablation. Despite advice to the contrary, the patient conceived twice while taking cinacalcet. Even though there are limited available data regarding the use of cinacalcet in pregnancy, both pregnancies continued to term with the delivery of healthy infants, using intensive medical management for persistent hypercalcaemia. Learning points Parathyroid carcinoma is a rare cause of primary hyperparathyroidism.Hypercalcaemia during pregnancy can result in significant complications for both the mother and the foetus.The use of high-dose cinacalcet in pregnancy has been shown, in this case, to aid in the management of resistant hypercalcaemia without teratogenicity.

    The authors report a case of carcinosarcoma (CS) of the fimbria of the fallopian tube in which carcinoma cells disappeared with neoadjuvant chemotherapy (NAC). A 74-year-old woman visited the present hospital with a large pelvic mass and pleural effusion. A magnetic resonance image of the tumor was highly suggestive of ovarian carcinoma. Due to the presence of both serous.adenocarcinoma cells in pleural effusion and pulmonary thrombosis, the patient was given NAC consisting of carboplatin plus paclitaxel (TC) and anticoagulant therapy with warfarin potassium. With six courses of NAC, the pleural effusion and pulmonary thrombosis disappeared, and the tumor decreased 36.2% in greatest diameter. Maximum debulking surgery was then performed. The tumor was found to be located in the fimbria of the right fallopian tube. Hysterectomy and bilateral salpingo-oophorectomy were performed, and histologic examination revealed chondrosarcoma with the presence of necrotic epithelial cells. The necrotic areas were interspersed with papillary structures, and immunohistochemical study showed positivity for CK7 and negativity for CK20, p53, and estrogen receptor (ER), indicating serous adenocarcinoma. Thus, heterologous CS with disappearance of viable carcinoma cells by NAC was diagnosed. The patient was given adjuvant chemotherapy consisting of three courses of TC, and there has been no evidence of disease for 20 months. The authors' experience in this case of gynecologic CS indicates that a serous adenocarcinomatous component of tubal CS can be well cured by TC-based NAC.

    Here, we report a case of cholangiocellular carcinoma that was successfully treated with chemotherapy using a selective intra-arterial infusion technique. A 65-year-old man presented to our hospital to obtain a second opinion regarding his disease. The patient was diagnosed with cholangiocellular carcinoma. The giant tumor was located in the porta hepatis. Some small nodules that were considered to be metastatic lesions were also observed in the surroundingarea. The tumor was judged by the primary physician to be too large for surgical treatment. Consequently, it was decided to treat the patient with trans-arterial chemoembolization(TACE)by selectingintra -arterial infusion of 5-FU, epirubicin(EPI), and mitomycin C prior to EPI-loaded HepaSphere(super-absorbent polymer microsphere)embolization, combined with concurrent systemic gemcitabine chemotherapy. After 5 sessions of the above treatment, the primary lesion reduced dramatically in size. In addition, the levels of CEA and CA19-9 decreased from 34.2 to 2.6 ng/mL and 1,540 to 149 U/mL, respectively. Although the patient's initial life expectancy was only 3 to 6 months, his life expectancy was extended to as longas 26 months followingthe initiation of TACE. This case suggests that treatment with TACE together with systemic chemotherapy can be a powerful therapeutic option for patients with inoperable cholangiocellular carcinoma.

    Evaluation of the malignant potential of a pheochromocytoma (PCC) remains controversial. PCC is regarded as a neuroendocrine tumor (NET), and the classification of NETs has gradually been defined over the last decade, particularly for gastroenteropancreatic NET. The present study describes a case of locally advanced, carcinoma-like, nonfunctional PCC, which may be regarded as neuroendocrine carcinoma (NEC) rather than a malignant PCC. A 72-year-old man was referred to Saitama Red Cross Hospital (Saitama, Japan), presenting with a 2-month history of right flank pain. Computed tomography revealed a right adrenal gland tumor, which measured 6.0 cm in diameter, invading the hilum of the right kidney, liver and inferior vena cava (IVC). Radical surgery was performed with en bloc resection of the right kidney, and adjacent parts of the liver and IVC. Immunohistochemical examination demonstrated that all of the resected tissues were positive for cytokeratin AE1/AE3, chromogranin A, synaptophysin, cluster of differentiation 56 and Ki-67, and the specimen had a Ki-67 index of 80%. A diagnosis of carcinoma-like PCC or NEC of the adrenal gland was confirmed. Reports of NEC of the adrenal gland are extremely rare in the literature, and classification of PCC as a NET has not yet been fully discussed. The present case may therefore contribute to the classification of NETs in the adrenal gland. PMID:27446458

    Mammary analog secretory carcinoma of salivary glands is a relatively recently recognized entity that harbors the ETV6-NTRK3 fusion transcript. To date, only rare cases of mammary analog secretory carcinoma of the skin have been reported. A 57-year-old man presented with a 6.0 cm cystic mass in the axilla, involving the dermis and superficial subcutis. Microscopically, the tumor exhibited nodular aggregation of tubular and microcystic structures embedded in the dense fibrotic and hyalinized stroma. Characteristic 'colloid-like' eosinophilic secretory material was present within intraluminal spaces. Tumor cells were largely characterized by vesicular nuclei with inconspicuous nucleoli and pink vacuolated cytoplasm. With respect to immunohistochemistry, tumor cells were intensely positive for AE1/AE3, Cam 5.2, and CK7, whereas Ber-EP4 and CEA were completely negative. A dual color break-apart fluorescence in situ hybridization probe identified rearrangement of the ETV6 gene locus on chromosome 12. The patient is alive with no evidence of recurrent disease or metastasis 3 years after the initial surgery. In conclusion, we report a rare example of mammary analog secretory carcinoma of the skin with ETV6 rearrangement. Awareness of this unique cutaneous tumor and subsequent reporting of additional cases is necessary for better characterization of its completely clinicopathologic spectrum.

    Intraductal papillary mucinous neoplasm (IPMN) of the pancreas often contains multifocal lesions, and total pancreatectomy is sometimes needed for curative resection. We report here our experience with a case of IPMN with multiple invasive carcinoma foci that was successfully treated with total pancreatectomy. A 66-year-old man had jaundice, and a computed tomography (CT) scan revealed a hypovascular mass in the pancreas head in conjunction with calcification and dilation of the entire main pancreatic duct. He was diagnosed with pancreas head cancer and chronic pancreatitis, and a pancreaticoduodenectomy was planned. Intraoperative pathological examination revealed papillary growth of high grade dysplasia in the main and branch duct epithelium and perineural invasion of the atypical glands. After 2 additional resections, we performed a total pancreatectomy. Pathological findings showed that the pancreas head tumor was an invasive carcinoma derived from main-duct IPMN of the pancreas. It was a mucinous carcinoma with calcification. Moreover, we found other multiple, discontinuous invasive foci in the body and tail of the pancreas which were undetectable by preoperative imaging. This case was highly suggestive for preoperative diagnosis for pancreas tumor and developmental pattern of main-duct IPMN.

    Fewer than 25 cases of hepatoid carcinoma of the pancreas have been reported in the literature. We present a case in a 61-year-old male with a remote history of Hodgkin's lymphoma and gastric neuroendocrine cell hyperplasia. On surveillance endoscopic ultrasound, an 8 × 5 mm cystic lesion was seen in the tail of the pancreas. MRI showed a focal pancreatic duct cut-off with mild ductal dilation. Fine needle aspiration was performed, which was concerning for acinar cell carcinoma. The patient underwent distal pancreatectomy and recovered uneventfully. Final pathology demonstrated a 1.3-cm hepatoid carcinoma of the pancreas, with a final clinicopathological stage of T1N0M0. Next-generation nucleic acid sequencing of the tumor did not suggest a viable adjuvant chemotherapeutic agent, and no adjuvant therapy was administered. The patient has no evidence of disease 6 months following resection. A further characterization and description of the outcomes of these rare tumors is warranted to help guide providers and counsel patients. PMID:27920649

In this article, we present the case of a Germ cell carcinoma during pregnancy is rare. However, its detection has increased due to the use of ultrasound fetal monitoring in the antenatal care program. In this article, we present the case of a pregnant 27-year-old diagnosed with an adnexal germ cell carcinoma at six weeks of gestation, whose initial approach was local resection (suboptimal cytoreduction). Four weeks after surgery, the patient presented with grade IV peripheral neuropathy in the lower limbs; magnetic resonance imaging scan indicated an infiltrative lesion at D5. The local medical board decided on chemotherapy starting on the 19th week of gestation. The rest of the pregnancy period was uneventful and the patient had a cesarean section at 34 weeks of gestation and a live newborn with no complications. Unfortunately, four days after caesarean section, the patient died of a septic shock with respiratory focus.

    Adenoid cystic carcinoma is a rare malignancy, usually found in the salivary glands, although this unusual tumor can be found at other sites of the body. In particular, regarding adenoid cystic carcinoma of the cervix (ACCC) most frequently reports are given for postmenopausal women. In this respect, our work is one among very few in the literature that considers a cytologic picture of this uncommon cervix carcinoma. The case of 74 year old patient with postmenopausal bleeding is described. Both Pap smear and air dried smear of the uterine cervix were analyzed. The cytologic findings revealed very few small clusters of abnormal glandular cells, as well as some amorphous eosinophilic globule-like material, with granulomatous and necrotic background. The latter includes a lot of histiocytes, multinucleated giant cells, large aggregates of epitheloid cells and lymphocytes. Histology revealed the diagnosis of ACCC. We emphasize the importance of careful screening of Pap smear that might be crucial in the case of suspicious clinical findings in postmenopausal women, when the possibility of ACCC has to be considered.

    Dermatomyositis is an autoimmune inflammatory myopathy associated with dermatologic findings. Its association with neoplasms is widely reported and has been shown to be higher in lung cancer, particularly small-cell carcinoma, probably as it originates from neuroendocrine cell precursors, as well as breast and ovarian cancer. The low frequency of dermatomyositis makes it difficult to suspect the underlying lesions among the diagnostic possibilities of systemic diseases with cutaneous manifestations. Therefore, the high probability of a neoplasm should always be considered, with reports of up to 75% in the eastern population and about 40% in general. In this report, we present a rare case of dermatomyositis with lesions in a shawl-like distribution, as a symptomatic debut of a small cell lung carcinoma.

  2. Transitional cell carcinoma of the ovary: A rare case and review of literature

    2010-01-01

    Introduction Transitional cell carcinoma (TCC) of the ovary is a rare, recently recognized, subtype of ovarian surface epithelial cancer. Case presentation A 69-year-old postmenopausal woman presented with a 2-year history of progressive enlargement of an abdominal mass. Abdominal computed tomography showed a pelvic mass. CA-125 was normal. A staging operation with total abdominal hysterectomy, bilateral salpingo-oophorectomy, infracolic omentectomy and pelvic lymph node dissection was performed. After surgery, the pathologic report of the right ovarian tumour was TCC, grade 3, stage IC. The patient underwent 3 cycles of chemotherapy: carboplatin and paclitaxel. She is regularly followed up and has been disease free for 10 months Conclusion Transitional cell carcinoma (TCC) of the ovary is a rare subtype of epithelial ovarian cancer. Surgical resection is the primary therapeutic approach, and patient outcomes after chemotherapy are better than for other types of ovarian cancers. PMID:21073751

    Clear cell carcinoma (CCC) is a rare low-grade carcinoma that represents only 1% to 2% of all salivary glands tumors. The finding of a clear cell tumor in a parotid gland involves the necessity of differential diagnosis between primary clear cell parotid tumors and metastases, mainly from kidney. The biological behavior is not very aggressive and development, which is very slow, is usually asymptomatic and indeed, the tumor often reaches considerable dimensions before being diagnosed. The treatment of choice is the surgical excision. There are rare cases of local recurrence and distant metastases. The aim of this article is to report a primary CCC in the parotid gland that microscopically closely resembled a metastatic CCC of renal origin, making microscopic differentiation difficult.

    Renal medullary carcinoma is rare and extremely aggressive neoplasm that typically affects young patients of African decent who demonstrate sickle cell trait or disease. Since the original description in 1995, only few cases have been reported outside the United States. A 29 year-old Canadian male of Afro-Caribbean decent with sickle cell trait developed right-sided hemiparesis due to brain infarct. During the clinical work-up, a 3 cm renal tumor was detected in a horseshoe kidney. The patient died suddenly 2 weeks after the presentation of massive non-neoplastic pulmonary thromboembolism, confirmed at autopsy. The final diagnosis of renal medullary carcinoma was established after the autopsy. Due to the small size of the tumor and the limited metastatic spread only to the regional lymph nodes, the tumor was considered an incidental finding, and not the primary cause of patient's death.

    A 91-year-old man presented with an ulcerated nodule on his left lower eyelid. The tumor showed an epithelial component composed of basaloid and clear cells and a stroma that contained many osteoclastic giant cells. Strong, diffuse expression for cytokeratin 17 and p63 was noted in the epithelial component, whereas no staining was present in the sarcomatoid stroma, suggesting that the osteoclast-rich stromal component represented an unusual benign stromal reaction to the carcinoma rather than a manifestation of carcinosarcoma. Further supporting this interpretation was the absence of mitotic figures and low Ki-67 proliferation index (of approximately 1%) in the stromal cells. We herein reported a case of unusual infiltrative basal cell carcinoma, accompanied by a clear cell carcinomatous features and concurrent benign osteoclastic stromal changes.

    Squamous cell carcinoma of the conjunctiva is the most frequent malignant tumor of the ocular surface. It is a rare disease with an incidence of 0.13 to 1.9 per 100,000 inhabitants, mainly affecting individuals between 50 and 75 years of age. It tends to have a slow, non-aggressive course. Treatment depends on the extent of the tumor. If there is intraocular involvement, enucleation is indicated, and in the presence of extraocular involvement the orbital exenteration is the standard treatment. We report and discuss the case of an 82 year old male patient having a conjunctival squamous cell carcinoma with intra and extraocular involvement, together with a review of the literature.

    Despite improvements in cytotoxic chemotherapy agents over the last 50 years, the outlook for patients with many of the most common solid tumours has remained poor. However, in recent years a number of targeted therapies have been licensed in the European Union for use in these cancer types. One such therapy, a tyrosine kinase inhibitor (sorafenib) is now used to treat patients with advanced hepatocellular carcinoma (HCC) and metastatic renal cell carcinoma. This article will explore the role of the oncology nurse in managing patients receiving sorafenib for advanced HCC. A brief overview of sorafenib as a current treatment approved for advanced HCC in the palliative setting is presented. This is followed by a case study-based discussion with particular reference to some of the key care coordination challenges facing the oncology nurse. The management of treatment-related adverse events and the importance of using a multidisciplinary team approach is also reviewed.

    Three men and 2 women with ages ranging from 37 to 70 years, clinically and histologically confirmed solitary, palpable metastatic cancers to the thyroid (SMCT) and preoperative cytologic investigation of their thyroid lesions by fine-needle aspiration (FNA), were reviewed. Four patients were known to have a solid cancer treated by radical surgery 1 to 4 years prior [1 bronchogenic squamous cell carcinoma, 1 parotid adenoid cystic carcinoma, 1 renal cell carcinoma (RCC) and 1 cutaneous melanoma], and 1 patient had no past history of cancer. Direct smears prepared from the patients' thyroid FNAs were fixed in 95% ethanol and stained with the Papanicolaou method. In 3 cases, immunostaining of the aspirated tumor cells with thyroglobulin antibody was performed, and in 1 case an aspiration smear was stained with commercial HMB-45 antibody. A correct cytodiagnosis of metastatic cancer to the thyroid was made in all 5 cases. In 1 patient the thyroid FNA revealed a metastatic RCC that led to the discovery of a clinically occult RCC. All 5 patients died of metastatic disease 27 to 40 months after surgical resection of their SMCTs. PMID:17263878

    Thyroid nodules are encountered in clinical practice during the diagnostic procedures or patients' follow-up due to other diseases quite far from the thyroid gland with prevalence 4-50% in general population, depending on age, diagnostic method and race. The prevalence of thyroid nodules increases with age and their clarification should be done for their adequate treatment. An 18F-FDG PET/CT was done with a PET/CT scanner (Philips Gemini TF), consisting of dedicated lutetium orthosilicate full ring PET scanner and 16 slice CT. The PET/CT scan of the whole-body revealed on the CT portion a hypodense nodular lesion in the left lobe of the thyroid gland with increased uptake of 18F-FDG on the PET with SUVmax 10.3 and demonstrated a complete response to the induction therapy of the main oncological disease of the patient--squamous cell carcinoma. This clinical case demonstrates that whole-body 18F-FDG-PET/CT has an increasingly important role in the early evaluation of thyroid cancer as a second independent malignant localization. Focal thyroid lesion with high risk of thyroid malignancy was incidentally found on 18F-FDG PET/CT.

    The authors have recently proposed to use the name pachyonychia as an umbrella term that includes 2 distinctly different entities in the form of congenital pachyonychia and acquired longitudinal pachyonychia. Congenital pachyonychia is defined by a diffuse hyperkeratosis of the nail bed. Acquired longitudinal pachyonychia correspond to the true definition of pachyonychia, that is, a thickened nail plate without subungual keratosis. Acquired (monodactylous) pachyonychia can be diffuse typifying onychomatricoma or localized as a longitudinal band with three etiological possibilities: onychomatricoma, onychocytic matricoma, and onychocytic carcinoma. On histopathological examination, onychomatricoma is a fibroepithelial tumor; conversely, onychocytic matricoma and carcinoma are purely epithelial tumors. The purpose of this study was to present the clinical, pathological, and immunohistochemical profiles of 2 cases of in situ onychocytic carcinoma, to discuss the role of high-risk human papillomavirus in the pathogenesis of this tumor, and to confirm the interest value of nail clipping microscopy in the surgical planning of the acquired (monodactylous) pachyonychia band pattern. Two men were referred for a longitudinal thickening of the lateral part of the nail plate of their fingers. The bands were yellowish with a faint to dominant black coloration. Nail clippings were obtained before excision in one case; the nail plate was thickened with minute holes in a honeycomb pattern. Nail biopsy specimens revealed an onychocytic carcinoma with epithelial projections inducing active production of the nail plate and multiple minute cavitations into the thick nail plate. Hair-related keratins were expressed in all specimens. One tumor expressed p16 in a diffuse pattern, whereas the other showed an unspecific faint patchy staining. p53 was negative.

    Retroperitoneal liposarcoma (RPLS) is a rare malignant tumor yet with a high recurrence rate. It is mostly observed in limbs and during retroperitoneal clearance, and accounts for nearly 40% of all adult retroperitoneal soft tissue sarcomas [1]. Renal cell carcinoma (RCC) is a common cancer developed in urinary system and its occurrence rate accounts for 3% of whole body malignant tumors [2]. In this report, we present a case of large perirenal liposarcoma associated with RCC, which is to date the fourth identified case. We analyzed the clinical pathologic data of this patient and reviewed the other three cases. Compared to the other cases, this patient is diagnosed at the youngest age and the liposarcoma tumor is with the largest diameter. Moreover, we have been following up the patient after operation for the longest time. All of these made this report rare and important. PMID:25550981

    Metastatic carcinoma to the vulva is rare, where the incidence is believed to be between 5% and 8%. However, malignant tumors have been described in 3–11% of systemic scleroderma (SSc) cases. We report the case of one patient, a 66-year-old postmenopausal woman, whose medical history was marked with rheumatic vascular disease (systemic scleroderma) since 1993 without muscular, renal, cardiac lesions or HTA (arterial hypertension) and without tobacco history. The woman presented with a new vulvar mass of the right labia in December 2011 that had progressively enlarged in size. CT scan of the abdominopelvic region demonstrated a lobular mass of the right labia with central necrosis, 7 cm on the wide axis, and the rectum and the vaginal wall were normal. No inguinal or iliac lymphadenopathy was noted. An outpatient excisional biopsy revealed a poorly differentiated malignant tumor suggestive of carcinoma. IHC: CK7+/CK20−, estrogen receptors−, AE 1 AE 3+, vimentine+, S100−, Desmina−, CD34−, KI 67: 20%. The thoracic scan revealed a large mass of 4 cm × 3 cm in the right lung base with right paratracheal lymphadenopathy 3 cm × 2 cm. A bronchoscopy revealed discrete stenosis of the mediastinal portion of the right bronchial tree. The bronchial biopsy also revealed poorly differentiated lung carcinoma, non-small cell, which was identical with the vulvar tumor. Conclusion The presence of the single lung lesion with only one lymphadenopathy paratracheal with pathological and immunohistochemical (IHC) profile similar to the vulvar lesion, and a particular IHC profile with CK7+ and CK20− was detected – that is more specific to the primitive pulmonary cancer, and the presence of only one sarcoma marker vementine+, desmine and actine−. Also the presence of KI 67: 20%, predicted the proliferative and great metastatic power of the lung tumor was observed. Additionally, lung cancer was the most frequent type and may develop in scleroderma as reported in

    Mammary analogue secretory carcinoma (MASC) is a recently described tumor sharing the histologic, immunohistochemical, and molecular profile of secretory carcinoma of breast. We aimed to evaluate the morphologic and histochemical features needed/required for the diagnosis of MASC without adjunct of molecular analysis. Six retrospective cases suspicious for MASC and 5 prospective cases reported as MASC were included in the study. Molecular analysis of ETV6 by fluorescence in situ hybridization was performed at the University of Pittsburg, USA. The ages of the patients ranged from 9 to 60 years (mean, 27.5 years). Histologically, all tumors showed mixed growth patterns including microcystic, macrocystic, papillary, tubular, and solid, papillary the being most common pattern. The tumor cells showed round to oval vesicular nuclei with small nucleoli, and eosinophilic to vacuolated cytoplasm. All cases demonstrated luminal and cytoplasmic mucin on periodic acid-Schiff with and without diastase digestion and alcian blue stain. ETV6 fusion gene rearrangement by fluorescence in situ hybridization was detected in 10 of 11 tumors. Recurrences occurred in 3 patients, and 1 patient died of disease 5 years after surgery. In conclusion, MASC is a relatively rare salivary gland malignancy exhibiting distinct histologic and histochemical features which can help to differentiate it from other mimics. Histologically, papillary-cystic and microcystic patterns are the main clues to diagnosis. The follicular pattern of acinic cell carcinoma might represent MASC, as 4 cases in our series had this pattern. Two patients in our series were 9 and 9½ years old respectively, which are the youngest ages ever recorded for MASC.

    Context: Follicular thyroid cancer rarely manifests itself as a distant metastatic lesion. Case Report: We report a case of a 41-year old man presented with a solid mass located in the left temporo-occipital region. The 3D computed tomography showed a large solid mass with high vascularity, skull erosion and supra-infratentorial epidural mass effect. After magnetic resonance imaging (MRI) a suspect diagnosis of meningioma was made. The patient underwent surgery where a soft mass with transverse sinus invasion was encountered; the tumour was successfully resected employing microsurgical techniques. Histological examination revealed a thyroid follicular neoplasm with positive staining for follicular carcinoma in immunohistochemical analysis. Postoperatively levels of thyroid hormones were normal. Treatment was planned for the thyroid gland, patient receiving 6 courses of chemotherapy including paclitaxel. Conclusions: The present case emphasizes that although they are uncommon, dural metastasis can be mistaken for meningiomas. The definitive diagnosis of a meningioma should be established only after the histopathological analysis. Thyroid follicular carcinoma should be included in the differential diagnosis in cases of extrinsic tumoral lesions. PMID:22540062

    Primary fallopian tube carcinoma is an extremely uncommon neoplasm of the female genital tract. Primary Fallopian Tube Carcinoma (PFTC) has a clinical and a histological resemblance to Epithelial Ovarian Cancer (EOC). We are reporting a case of PFTC in a 55 year old tubectomized, postmenopausal woman with the non-specific complaints of a watery vaginal discharge and lower abdominal pain. The clinical and radiological findings suggested a bilateral tubo-ovarian abscess. On laprotomy, a bilateral fallopian tube tumour was seen, with a focal extension to the surface of the right ovary from the right fallopian tube. Total abdominal hysterectomy, bilateral adnexectomy andomentectomy, along with excision of the draining lymph nodes, was done. The histopathological examination revealed a bilateral papillary serous carcinoma of the fallopian tube. The patient was treated with adjuvant chemotherapy with Paclitaxel. There was no evidence of any recurrence, after 2 years of regular follow up. The clinical signs and symptoms of fallopian tube neoplasms are usually non-specific. The primary treatment remains a surgical resection, followed by adjuvant chemotherapy or radiation. The prognosis is poor, although long-term survivors have been reported. PMID:23814748

    Ameloblastic carcinoma (AC) is a rare malignant odontogenic neoplasm that tends to occur in the mandible rather than in the maxilla. This malignancy is classified as a tumor that combines the morphological features of ameloblastoma and carcinoma, regardless of the presence or absence of metastasis. In addition, AC has been classified into two types, primary and secondary. The former develops de novo and the latter develops by malignant transformation of a pre-existing benign ameloblastoma. The present study describes the case of a 22-year-old patient with primary AC of the maxilla. A review of the literature focusing on the clinical details, treatment results and histopathological and phenotypic information available for ameloblastic carcinoma of the maxilla from a 60-year period was also performed. As a result, it was found that primary AC is dominant in the maxilla and does not exhibit an aggressive phenotype compared with secondary AC. In addition, the presence of recurrence was found to correlate with mortality, indicating that early, aggressive and complete removal of the tumor is the best treatment for survival. PMID:25436009

    Introduction. Merkel cell carcinoma is a rare, aggressive neuroendocrine cell carcinoma arising in the sun-exposed skin of elderly patients. Most of these tumors are located in the dermis. An unusual clinical presentation of such a tumor in the subcutis, if not biopsied, may be easily mistaken as a benign lesion. Case Presentation. An 83-year-old white woman presented with a several-month history of a painless 7 mm subcutaneous mass that was initially thought to be a lipoma. A conservative follow-up was planned. At the insistence of the patient, an excisional biopsy of the mass was performed revealing a subcutaneous Merkel cell carcinoma. The tumor cells stained positively for CK 20, chromogranin, and synaptophysin. No other primary or metastatic tumors found after a thorough work-up. The patient was treated with local irradiation. She remains disease free at her six-month follow-up visit. Conclusion. When a new growth is encountered in the sun-exposed skin of elderly patients, a biopsy is warranted even if the lesion clinically appears benign.

    Papillary renal carcinoma (papillary RCC) is a histological subtype of the renal carcinoma, which in turn, has two morphological subtypes that correlate with prognosis. The present study reported an unexpected finding of type 2 papillary renal cell carcinoma (papillary RCC) presenting intracystic necrosis cavity. A cystic renal lesion was identified incidentally in a 66-year-old man during an abdominal computed tomography (CT) scan performed for the evaluation of a gastrointestinal stromal tumor. Subsequent contrast material-enhanced CT scan and magnetic resonance imaging (MRI) examination labeled the mass as category III degree on the basis of the Bosniak classification scheme. Surgical exploration by laparoscopic radical nephrectomy was performed to determine the diagnosis. Definitive pathological study confirmed a type 2 papillary RCC with an intracystic necrosis cavity. To the best of our knowledge, this case demonstrated for the first time a cavity within a papillary RCC, supporting the hypothesis that type 2 papillary RCC could develop cavity avascular necrosis during its cystic degeneration.

    The aim of this study is to present the casuistic of mucoepidermoid carcinoma of salivary glands in patients diagnosed at "Dr. Eduardo Cáceres Graziani" National Institute for Neoplastic Diseases, Lima, Perú. From January 2002 to December 2012, 51 cases were diagnosed as mucoepidermoid carcinoma. The number of female patients was higher, with 28 cases (54.9%), and regarding age distribution, 33.3% of the patients were under 30 years old. Pain was one of the main symptoms, and 74.5% of the mucoepidermoid carcinomas were located in the parotid gland. It is concluded that epidemiology regarding age and gender of the 51 cases analyzed was in the same range as other studies, and that most cases were located in major salivary glands, in agreement with reports on other populations. Other characte ristics showed a homogeneous distribution.

    Gorlin-Goltz (GS) syndrome is an autosomal dominant disease linked to a mutation in the PTCH gene. Major criteria include the onset of multiple basal cell carcinoma (BCC), keratocystic odontogenic tumours in the jaws and bifid ribs. Dermoscopy and reflectance confocal microscopy represent imaging tools that are able to increase the diagnostic accuracy of skin cancer in a totally noninvasive manner, without performing punch biopsies. Here we present a case of a young woman in whom the combined approach of dermoscopy and RCM led to the identification of multiple small inconspicuous lesions as BCC and thus to the diagnosis of GS syndrome.

There is very little evidence regarding the natural history and treatment options for patients developing HCC recurrence after LT. Surgical resection offers a unique opportunity for solitary metastasis. We report a 61 year old male with solitary right adrenal metastasis 15 months post LT which was managed with open adrenalectomy. The patient is alive and disease free 24 months after the surgery. The case, histo-pathological findings and literature review is discussed.

    Most patients with thyroid bone metastases have been evaluated in accordance with other sites of disease. Overall survival is impacted and the results with surgery, radiation therapy, or radioactive iodine show variable results. Four cases are presented: three women and one man with an age range of 43-53 years and all with radical surgery. Good local control in three of the patients was observed. All patients had hormonal suppression with levothyroxine. Radical surgery showed an improvement in survival in patients with bone metastases for thyroid carcinoma.

    Many kinds of malignant disorders present as exfoliative dermatitis (erythroderma), however, coincident clearcell renal cell carcinoma (ccRCC) and erythroderma has not been reported. A case of synchronous erythroderma and ccRCC in a 57-year-old man is presented presented here. After the diagnosis of the kidney bulk through CT, the patient had a transperitoneal laparoscopic radical nephrectomy, and the syndrome of the erythroderma disappeared after the surgery. The experience of the current patient suggests that the syndrome of erythroderma may resolve spontaneously after radical nephrotomy.

    Cutaneous metastasis from visceral tumors is a rare entity with a reported incidence between 0.3% and 9.8%. These usually occur late in the course of the disease; the average time interval between the diagnosis of malignancy and presentation of cutaneous metastases has been reported to be 33 months. In rare instances (in about 0.8%–1.3% of patients), cutaneous metastases may be a pointer to an underlying undiagnosed malignancy. We report two patients presenting to us with soft, nodular, cutaneous lesions, which was the manifestation of metastatic signet cell carcinoma arising from the gut. We report these cases owing to their rarity. PMID:27559503

    Introduction At time of presentation, fewer than 10% of patients have metastatic breast cancer. The most common sites of metastasis in order of frequency are bone, lung, pleura, soft tissue, and liver. Breast cancer metastasis to the uterus or gallbladder is rare and has infrequently been reported in the English literature. Presentation of case A 47 year old female with a recent history of thrombocytopenia presented with abnormal vaginal bleeding. Pelvic ultrasound revealed multiple uterine fibroids and endometrial curettings revealed cells consistent with lobular carcinoma of the breast. Breast examination revealed edema and induration of the lower half of the right breast. Biopsy of the right breast revealed invasive lobular carcinoma. Bone marrow aspiration obtained at a previous outpatient visit revealed extensive involvement by metastatic breast carcinoma. Shortly after discharge, the patient presented with acute cholecystitis and underwent cholecystectomy. Microscopic examination of the gallbladder revealed metastatic infiltrating lobular carcinoma. The final diagnosis was invasive lobular carcinoma of the right breast with metastasis to the bone marrow, endometrium, gallbladder, regional lymph nodes, and peritoneum. Discussion The growth pattern of invasive lobular carcinoma of the breast is unique and poses a challenge in diagnosing the cancer at an early stage. Unlike other types of breast cancer, it tends to metastasize more to the peritoneum, ovary, and gastrointestinal tract. Metastasis to the endometrium or gallbladder is rare. Conclusion Metastatic spread should be considered in the differential diagnosis of patients with invasive lobular breast carcinoma presenting with abnormal vaginal bleeding or acute cholecystitis.

    The breast is an extremely rare target organ for metastasis of extramammary neoplasms. The occurence varies between 1.7% to 6.6% in autopsies; between 1.2% and 2% in clinical cases; and around 2.7% in sputum series. In accordance with the primary tumor localization, it is more common to find metastases of lymphoma, melanoma, rhabdomyosarcoma, tumors of the lung and ovarian tumors. Breast metastasis of the uterine cervix is a very seldomly found. According to the published literature so far there have been around 30 documented cases with such pathology. This study presents the case of a 48-year-old female with a squamous cell carcinoma of the uterine cervix, which was histologically verified in 2010. Three years after the initial tumor diagnosis, radiotherapy and chemotherapy, the patient was found to have a cystic tumor formation in one of her breasts. The formation was painful to pressure. Quadrantectomy with an open bisopsy was performed to the patient. Histological and immunohistochemical diagnosis rejected primary squamous cell carcinoma of the breast. The differential diagnosis of metastatic lesions in the breast is problematic and requires careful clinical history, immunohistochemical study and multidisciplinary approach in the management. Mammary metastases are a bad predictor and they serve as an indicator of generalized dissemination of the primary tumor process.

    Glycogen storage diseases (GSD) are inherited metabolic disorders of glycogen metabolism due to intracellular enzyme deficiency resulting in abnormal storage of glycogen in tissues. GSD represents an indication for liver transplantation (OLT) when medical treatment fails to control the metabolic dysfunction and/or there is an high risk of malignant transformation of hepatocellular adenomas (HCA). Herein we have reported two cases of GSD, type Ia and type VI, which were both associated with rapidly growing HCA, and underwent OLT because of suspect changes in their radiological features. Final histological findings in the explanted liver showed the presence of hepatocellular carcinoma (HCC) in both cases. In GSD type Ia and VI, OLT is considered to be the treatment of choice when a liver neoplasm is suspected. While the association of HCC with GSD type Ia is well known, this is the first case of HCC in GSD type VI so far reported to the best of our knowledge.

    Clear cell squamous cell carcinoma (SCC) is a rare variant of SCC of skin in which ultraviolet radiation has been suggested as possible etiology. This case is that of a 62-year-old male concrete block maker/bricklayer who presented with a 6 months history of a non-healing ulcer on the left side of his face. Histology showed features of malignant epithelial neoplasm composed of islands of large oval to polyhedral malignant squamous cells with eosinophilic to amphophilic cytoplasm and vesicular nuclei and there were areas showing clear cell differentiation and isolated areas of keratin pearl formation. The lesion was also negative for periodic acid schiff, mucicarmine, and alcian blue stains but was strongly positive for AE1/AE3 (immuno-stain). This case showed an aggressive and bizarre clinical presentation but more report of cases are needed to have a better characterization of the clinical presentation and prognosis of this variant of SCC.

    A case of ductal carcinoma in-situ (DCIS) associated with prolactinoma in a male patient is described. A 56-year-old gentleman presented with lethargy and loss of libido. His prolactin at presentation was 3680 mU/l and an MRI scan of the head revealed a pituitary tumour suggestive of prolactinoma. Following 18 months of treatment with cabergoline, the prolactin level reduced to 914 mU/l. However, 3 years later he presented with blood stained nipple discharge, the cytology of which was negative for cancer. Ultrasound scan of his right breast revealed a single dilated mammary duct. Microdochectomy was performed. The histology revealed incompletely excised DCIS. There is increasing evidence of prolactinoma associated with breast cancer with or without DCIS in females. A review of the literature reveals only one previous case report of this association in males. This is the first case of pure DCIS preceded by prolactinoma in a male patient.

    This report describes the case of a patient who underwent total gastrectomy, splenectomy and pancreatomy corporo-postero as a consequence of gastric and pancreatic metastasis from carcinoma to clear cells, five years after having undergone radical nephrectomy. Upper digestive bleeding was the first symptom, and pancreatic lesion was detected in previous CT scans. There are many documented cases of pancreatic metastasis, but only eight gastric metastasis in the last 15 years, although we did not find reports about surgical treatment for concomitant gastric and pancreatic injury. Surgical treatment which in some reports include highly complex surgeries such as gastrectomies with combined resections of invaded organs and pancreatoduodenectomy, are good options for select cases, because good survival rates have been reported.

    Salivary gland-type tumors have been rarely described in the thyroid gland. Mammary Analog Secretory Carcinoma (MASC) is a recently defined type of salivary gland carcinoma characterized by a t(12;15)(p13;q25) resulting in an ETV6-NTRK3 fusion gene. We report 3 cases of MASC involving the thyroid gland without clinical evidence of a salivary gland or breast primary; the clinico-pathologic characteristics are reviewed. Assessment for rearrangement of the ETV6 (12p13) locus was conducted by fluorescence in situ hybridization (FISH) on representative FFPE sections using an ETV6 break apart probe (Abbott Molecular, Des Plaines, IL, USA). The patients were two females (52 and 55 years-old) and 1 male (74 years-old). The tumors were poorly circumscribed solid white tan nodules involving the thyroid. Histologically, they were invasive and showed solid, microcystic, cribriform, and tubular growth patterns composed of variably bland polygonal eosinophilic cells with vesicular nuclear chromatin and conspicuous nucleoli. All three cases showed metastasis to lymph nodes; one case showed lateral neck involvement. The tumor cells were positive for S100 and mammaglobin. GATA-3 and PAX-8 were positive in 2 cases, one of which only focally so. All three cases were negative for TTF-1 and thyroglobulin. Rearrangement of the ETV6 locus was confirmed in all cases and a diagnosis of MASC rendered for each case. A site of origin distinct from the thyroid gland was not identified, with a median follow up of 24 months. MASC may rarely involve the thyroid gland. The origin of these lesions is unknown; while an origin from ectopic salivary gland-type cells is entertained, a metastatic origin from an occult primary cannot be definitively excluded at this time. Given the histologic (follicular-like microcystic pattern with colloid-like secretions and papillary pattern), immunophenotypic (PAX-8), and even molecular overlap, MASC can be mistaken for papillary thyroid carcinoma and should be

    Uterine serous carcinoma (USC) is a rare variant of endometrial cancer that is not related to increased estrogen level; rather, it arises in a background of atrophic endometrium. Our aim was to describe clinicopathologic features of 4 cases of USC arising in endometrial polyps (EPs). The mean age of the patients at presentation was 53 years (range, 50-61 years). All patients presented with postmenopausal bleeding. In 3 patients, endometrial curretings were done before surgery, which was reported as EP with superficial foci of USC, EP with few clusters of atypical cells, and high-grade serous carcinoma, respectively. All patients underwent hysterectomy with bilateral salpingo-oophorectomy and omental sampling. The uterine cavity showed an EP in all cases ranging in size from 2 to 3.5 cm (mean, 3 cm). The hysterectomy specimens revealed USC in EP as well as the adjacent endometrium in 3 patients. The nonneoplastic endometrium was atrophic in all cases. Residual tumor was not found in the endometrium in 1 case. Omental metastatic deposits were found in all cases. Tumor deposits were also seen in the serosa of uterus, fallopian tubes, and parametrium in 1 case. Two patients died of disease 2 years after diagnosis. The remaining 2 patients are alive after a follow-up of 3 years, respectively. In conclusion, USC is a rare aggressive tumor, and to establish the diagnosis, it is important to look for the small foci of the tumor in the atrophic endometrium and on the surface of the polyps as these patients are likely to harbor additional disease in the uterus or extrauterine sites. The postmenopausal group is at high risk for developing these tumors; therefore, all the endometrial biopsies/curettings and the EPs in this age group should be thoroughly sampled.

    We report a case of primary small cell carcinoma of the urinary bladder. A 79-year-old man with the chief complaints of macrohematuria and pollakisuria was admitted to our hospital. Cystoscopy and computed tomography (CT) revealed a non-papillary broad-based bladder tumor. Histological diagnosis was small cell carcinoma of the urinary bladder, and he underwent 3 courses of neoadjuvant chemotherapy including gemcitabine and cisplatin with a preoperative diagnosis of cT3bN0M0. After the chemotherapy, cystoscopy and CT showed complete remission. Total cystectomy with ileal conduit was performed following 3 courses of chemotherapy. Microscopic examination revealed that the small cell carcinoma had disappeared and the converted squamous cell carcinoma remained only in a small part of the specimens. The patient was carefully followed for 10 months after operation, with no tumor recurrence.

    Clear cell papillary renal cell carcinoma (CCPRCC) is a recently recognized subtype of renal cell carcinoma entity after 2004 World Health Organization classification of renal tumors. CCPRCC has unique histomorphological and immunohistochemical characteristics. The distinction of CCPRCC from renal cell carcinoma (RCC) with clear cell morphology is crucial because the former is considered to have a favorable clinical outcome. CCPRCC may be interpreted in the past as other renal cell carcinomas, particularly low-grade clear cell RCC. In this study, the frequency of CCPRCC in previously diagnosed low-grade RCC and its clinicopathologic features were examined. A total of 126 cases of stage T1a with low nuclear grade RCC were identified from 625 consecutive RCCs removed by radical/partial nephrectomy over 12-year period (2000-2011). Archival tissue sections were retrospectively reviewed along with patient medical charts. Eight cases (1.3% of all RCC, 6.3% of pT1a low grade RCC) with characteristic histologic features of CCPRCC were confirmed by immunohistochemical studies. Seven cases were previously diagnosed as clear cell RCC and one as multilocular cystic RCC. Radiographically, CCPRCC favored a mid-pole location in the kidneys. At a median follow-up period of 52 months (range 20-114.5 months), there were no cases of local or distant recurrence. In conclusion, CCPRCC is not uncommon among small low-grade RCC tumors. CCPRCC can be correctly recognized by its unique histomorphological features and confirmed by immunohistochemistry studies, which is important due to the excellent clinical outcome following resection.

    Renal carcinomas associated with Xp11.2 translocations/transcription factor 3 (TFE3) gene fusion (Xp11 translocation RCC) are a rare subtype of renal cell carcinoma. A middle-aged Japanese man, who had a medical history of dialysis for more than 12 years, had bilateral renal cancers with a background of acquired cystic disease of the kidney and remarkable deposition of calcium oxalate in the tumorous area. The right renal tumor showed papillary architecture of clear cells with diffuse and strong immunoreactivity for TFE3 and focal and weak positivity for cathepsin K, suggesting a possibility of Xp11 translocation RCC. However, RT-PCR failed to detect any type of the reported fusion genes involving TFE3. Thus, the sample was sent for a TFE3 break-apart FISH assay in a renal tumor consultation service, which reported no evidence of TFE3 gene rearrangement. The right renal tumor was finally diagnosed as papillary renal cell carcinoma with cystic change. We report here a case of bilateral renal cell carcinoma in a patient undergoing long-term dialysis, which showed false-positive immunoreactivity for TFE3 immunostaining. Titration of TFE3 immunohistochemical staining (IHC) should be performed and cross-referenced with the FISH or RT-PCR results to avoid the misinterpretation of TFE3 IHC results.

    Branchiogenic carcinoma (BC) usually appears as a mass lesion with a predominant cystic component. Since lymph node metastasis from oropharyngeal carcinoma (OPC) has a cystic appearance, it is occasionally difficult to distinguish between BC and nodal metastases from clinically silent OPC. Factors associated with the malignant transformation process in BC remain obscure. The present study reports the case of a 56-year-old man with a right cystic cervical mass that was diagnosed as squamous cell carcinoma based on examination by fine-needle aspiration biopsy. The primary tumor could not be detected despite several imaging examinations, a pan-endoscopy of the head and neck, esophagus and stomach, biopsies of the head and neck regions, and bilateral tonsillectomies. The pathological findings of the surgical specimens from a radical neck dissection were consistent with the histological characteristics of BC, with evidence of transition from dysplasia through intraepithelial carcinoma to invasive carcinoma. Normal squamous epithelium and dysplastic and cancerous portions in the BC showed strong p16INK4a immunoreactivity. The expression of p16INK4a was also observed in all 9 nodal metastases in the neck dissection specimens. The cystic formation observed in the BC was not observed in the nodal metastases. As the presence of human papillomavirus-16 in the tumor was confirmed by polymerase chain reaction, quantitative polymerase chain reaction was employed for the measurement of human papillomavirus-16 viral load and integration. The results showed that the viral load of human papillomavirus-16 was 3.01×107/50 ng genomic DNA, and the E2/E6 ratio was 0.13, so the integration state was judged to be the mixed type. To the best of our knowledge, this is the first report of BC associated with high-risk-type human papillomavirus infection. The study indicates that a human papillomavirus-positive neck mass may not necessarily be OPC, but that it could be BC with a poor prognosis

    We report here a rare case of undifferentiated carcinoma of the pancreas mimicking main-duct intraductal papillary mucinous neoplasm. In an 80-year-old woman, an approximately 8-mm papillary mass was incidentally detected at the downstream edge of a dilatated main pancreatic duct lumen on CT and MRI. Main pancreatic duct dilatation in the pancreatic body and tail and parenchymal atrophy were observed in the upstream of the mass. Histopathologically, the tumor protruded into the downstream edge of the dilatated main pancreatic duct lumen in the pancreatic body. The tumor cells had highly atypical nuclei and abundant polymorphic structures, and showed positive staining for granulocyte colony-stimulating factor, which led to the diagnosis of undifferentiated carcinoma. A total of 13 cases of undifferentiated carcinoma with intraductal tumor growth have been reported to date. The case report by Bergmann et al. has been the smallest in histopathological specimen, and the present case is the smallest in size detected by radiological images. Since early undifferentiated carcinoma of the pancreas can resemble those of main-duct intraductal papillary mucinous neoplasm in cross-sectional images, we have to consider undifferentiated carcinoma in the differential diagnosis of the solitary and papillary mass with low contrast enhancement in early phase in the main pancreatic duct.

Cytologic diagnoses of malignancy were established in all tumors (three were reported as adenoid cystic carcinoma, two as adenocarcinoma not otherwise specified). Material for cytologic evaluation was satisfactory in all cases. Adenoid cystic carcinoma, polymorphous low-grade adenocarcinoma, papillary cystadenocarcinoma and cellular type of pleomorphic adenoma are the main differential diagnoses.

    Patient: Female, 60 Final Diagnosis: Gastroesophageal carcinoma with rectal metastasis Symptoms: Bloating • constipation • weight loss Medication: — Clinical Procedure: Endoscopy • flexible sigmoidoscopy • lower endoscopic ultrasound Specialty: Gastroenterology and Hepatology Objective: Unusual clinical course Background: Gastroesophageal cancers, previously considered rare, are rapidly increasing worldwide. We present here a unique case of gastroesophageal carcinoma with metastasis to the rectum. Case Report: A 60-year-old female patient presented with constipation, bloating, and weight loss of 4-month duration. She had undergone sleeve gastrectomy 6 years before. Endoscopies performed revealed a friable-looking mucosa in the lower esophagus and a polypoid rectal mass. Histopathological examination from both the esophageal and rectal lesions revealed poorly differentiated adenocarcinoma cells. Immunohistochemistry stain from both specimens was positive for CK7 supporting the gastric site primary with metastasis to the rectum. Further evaluation also revealed metastasis to bone and malignant pleural effusion. Chemotherapy with palliative intent was initiated. Conclusions: Colorectal metastasis is commonly seen from cancers of the breast, stomach, melanoma, kidney, prostate, and ovaries. However, colorectal metastasis from gastroesophageal cancer has never been reported in the medical literature. Diagnosis relies on histopathologic examination and immunohistochemical staining of the tumor. Treatment depends on the tumor stage. Tumors with widespread metastatic disease are candidates for palliative chemotherapy. PMID:27558656

    Fibroadenoma is the most common form of benign breast tumor and the most common breast tumor in women under 30 years of age. However, carcinoma arising within a fibroadenoma is unusual, with over 100 cases reported in the literature. Histological diagnosis is typically unexpected. A 46-year-old female with no family history of breast malignancies was admitted for an elastic hard lump in the upper-outer quadrant of her right breast. At a clinic that she visited previously, her condition was diagnosed by core needle biopsy with four specimens showing fibroadenoma with borderline atypical ductal hyperplasia at pathology. Excisional biopsy was recommended for pathological diagnosis. The patient requested a definitive diagnosis and alternative treatment to tumorectomy. More biopsy specimens were needed for pathological diagnosis; therefore, ultrasonography-guided vacuum-assisted core needle biopsies were obtained, confirming ductal carcinoma in situ with questionable microinvasion of intracanalicular- and pericanalicular-type fibroadenoma. Right breast-conserving surgery and sentinel lymph node biopsy were immediately performed for radical therapy. We present this case to increase awareness of this entity and stress the need for histological evaluation of some breast masses.

    We report here the case of a young man suffering from a rare germ cell tumour. The patient was a 25-year-old man who was referred to our centre for asthenia, stinging epigastric pain, and an iron deficiency anaemia. Gastroscopy revealed a circumferential vegetating lesion on the second portion of the duodenum. The lesion was indurated at the third portion of the duodenum, responsible for a tight stenosis. A computerized tomography-scan of the chest, abdomen and pelvis, and a pancreatic MRI showed a circumferential lesion with a bi-ductal dilatation (i.e., of the common bile duct and Wirsung’s duct) without metastatic localisation. The patient underwent a pancreaticoduodenectomy with lymph node dissection including all cellular adipose tissues of the hepatic pedicle from the hepatic common artery and of the retroportal lamina. Histological findings were suggestive of a duodenal embryonal carcinoma with pancreatic infiltration. This is the second published case highlighting the duodenal primitive localisation of an embryonal carcinoma with pancreatic infiltration. PMID:28216981

    Mucinous mammary carcinoma (MC) is a tumor type with relatively favorable prognosis. Unlike the circumstances surrounding conventional invasive duct carcinoma, data are limited regarding precursor lesions for MC. This study characterizes patterns of mucinous ductal carcinoma in situ (DCIS) as a precursor lesion for MC. All slides from 130 cases of MC encountered between 2000 and 2011 at Henry Ford Hospital, Detroit, MI were reviewed to subclassify MC, identify DCIS, and explore transition patterns from DCIS to MC. Calponin, p63, chromogranin, synaptophysin, CD56, and MIB-1 immunostaining analyses were performed in 65 cases. Among 106 cases of pure (71 type A, 35 type B) and 24 cases of mixed MC, DCIS appeared in 88 (68%) specimens, with all but 4 showing luminal mucin accumulation. Dominant patterns of mucinous DCIS were cribriform/solid (66), cribriform and papillary (7), papillary (5), micropapillary (3), and flat (3). Fifty-seven (68%) cases of mucinous DCIS demonstrated transitions from DCIS to MC. Luminal mucinous distention, focal flattening and attenuation of the epithelium, and disruption of the duct wall resulting in a mucocele-like extravasation of malignant epithelia with escaping mucin was a transition pattern seen with all architectures of DCIS and in all types of MC. This was the only pattern of transition to type A MC. The epithelial outpouching, formation of a cleft with accumulation of mucin around the epithelium, and transition into mucin pools with floating tumor cell clusters was the second transition pattern that went from cribriform/solid DCIS to type B and mixed MC. DCIS preceding aggressive phenotypes of MC (type B and mixed) more often had a cribriform/solid architecture, higher nuclear grade, and higher Ki-67-labeling index (all P<0.05). In summary, mucinous DCIS is a precursor to MC with distinctive features that link patterns of DCIS with aggressive MC phenotypes. The 2 observed transitions between mucinous DCIS and MC suggest that

    Mucin and mucin-like material are features of mucinous tubular and spindle renal cell carcinoma (MTS RCC) but are rarely seen in papillary renal cell carcinoma (PRCC). We reviewed 1311 PRCC and identified 7 tumors containing extracellular and/or intracellular mucinous/mucin-like material (labeled as PRCCM). We analyzed these using morphological, histochemical, immunohistochemical, and molecular genetic methods (arrayCGH, FISH). Clinical data were available for six of the seven patients (five males and one female, age range 61-78 years). Follow-up was available for four patients (2-4 years); one patient died of widespread metastases. Tumor size ranged from 3 to 5 cm (mean 3.8). Of all cases, histological architecture showed a predominantly papillary pattern. Mucin or mucin-like was extracellular in one, intracellular in three, and both intra/extracellular in three cases. All tumors were positive for AMACR, vimentin, and OSCAR, while CK7 was positive in four. Mucicarmine stain was positive in all cases, PAS in six and Alcian blue in three cases. Five tumors were positive for MUC 1, but none were positive for MUC 2, MUC 4, or MUC 6. In only four cases, genetic analysis could be performed. Gain of chromosomes 7 and 17 was found in two cases; gain of 17 only was found in one case. Loss of heterozygosity of 3p was found in one case together with polysomy of chromosomes 7 and 17. No abnormalities of VHL, fumarate dehydrogenase, and TFE3 genes were detected. We conclude that PRCCM is a rare but challenging subtype of RCC that deserves to be further studied. In all the tumors, the mucin-like material was found in those stained with mucicarmin, but other conventional and immunohistochemical stains did not reveal consistent features of a single mucin. The molecular-genetic profile of these tumors was most consistent with that of typical papillary RCC, although one case had mixed genetic features of papillary and clear RCC. PRCCM has metastatic potential, as evidenced by

    The authors presents a case of cribriform breast carcinoma in a cyst that clinically imitated an abscess. The case concerns a 71-year-old female patient treated for ankylosing spondylitis, with a positive family history of breast cancer. The patient presented at the surgical clinic for incision of an abscess of the mammary gland localized in the lower inner quadrant that was a consequence of previous trauma to the right breast. The abscess was incised and the serosanguineous contents were evacuated. The wound was drained and antibiotics (Dalacin with Metronidazol) were administered for the period of 10 days. During the treatment, a cutaneous fistula was formed. At the incision site, a hard thickening was palpable (tumor). Core needle biopsy of the clinically palpable tumor was performed and the purulent material from the fistula was collected for a culture test. Complete blood count did not reveal leucocytosis. In accordance with the obtained sensitivity report, the patient was started on antibiotics again. Breast ultrasound performed upon the completion of the antibiotic therapy, in the right breast, revealed two solidcystic oval lesions with thick echogenic walls and blurred margins. Both masses contained dense levels of fluid material and solid polycyclic structures. On sonoelastography, the lesions were heterogeneous with a high Young's modulus. In the right axillary fossa, ultrasound examination revealed three abnormal lymph nodes enlarged to 31 mm length, which were rounded, hypoechoic and without visible sinuses. Histopathology of the core needle biopsy performed at admittance and after the antibiotic therapy indicated a breast abscess (presence of fibrinous and partly fibrinopurulent material). The mass was finally resected to confirm histopathology. The resected material revealed the presence of an invasive, moderately differentiated cribriform carcinoma, which developed within a cyst, with a 40% necrotic component. Eighteen months after the commencement

    The aim is to report a rare case of squamous cell carcinoma arising in a urinary bladder diverticulum and present recent literature overview of treatment options. A 56-year-old man presented with intermittent hematuria. Ultrasound examination indicated primary carcinoma in the urinary bladder diverticulum. Diagnosis was confirmed with cystoscopy and computed tomography. Transvesical diverticulectomy with regional lymphadenectomy was undertaken. Two years after initial treatment, the patient was well without evidence of tumor relapse. This report implicates that although aggressive surgical approach is recommended in the majority of bladder diverticulum tumors, simple diverticulectomy may be indicated in selected, confined cases.

    This report describes a 50-year-old woman who presented to a community gynaecology clinic complaining of persistent heavy vaginal bleeding with an LNG 52 mg-IUS in situ. She was subsequently found to have stage 1 grade 1a endometrioid carcinoma. From the literature, we have identified five similar cases. This case highlights the possibility of endometrial carcinoma despite treatment with an LNG 52 mg-IUS and reinforces the importance of investigating women who present with unusual persistent or heavy vaginal bleeding.

    Hepatocellular carcinoma was diagnosed in five slender tailed meerkats (Suricata suricatta) housed at the Smithsonian Institution's National Zoological Park between 1980 and 2013. Animals included four females and one male, ranging from 7 to 15 yr of age. Common clinical signs included weight loss and lethargy. Three of the neoplasms originated from the right medial liver lobe and were located adjacent to or partially incorporated in the gall bladder. Three animals had solitary masses, and two animals had multiple hepatic masses; all were characterized by polygonal to round neoplastic hepatocytes arranged in a trabecular pattern with smaller regions of varied solid, adenoid, and rarely peliod cell patterns. Hemorrhage and necrosis often with cystic degeneration was noted in all five cases. There was no evidence of metastatic disease in any of the cases examined.

    The thyroglossal cyst can exceptionally appear as a primary cyst carcinoma. We discuss a series of 6 adult patients, assessed for long-lasting asymptomatic suprahyoid or lateral-to-larynx mass. The images showed a heterogeneous mass invading adjacent soft tissues. Fine needle aspiration biopsy did not contribute to diagnosis. We performed a Sistrunk procedure in all cases, 3 combined with total thyroidectomy and 1 with neck dissection. The postoperative course was favourable. No additional treatment was required, without evidence of recurrence in follow-up. The management is controversial due to the limited number of cases reported. Some classifications based on size and extent have been proposed to define the surgical treatment of such cysts.

    Ameloblastic carcinoma (AC) is an uncommon malignant odontogenic tumor that can be difficult to differentiate from ameloblastoma and can arise directly as an undifferentiated lesion or from a pre-existing benign lesion. The current study presents a novel case of primary maxillary AC and review the literature on AC of the maxilla. The review of the literature indicates that secondary tumors and posterior localization are associated with a higher tendency for recurrence and, often, multiple recurrences. Surgical therapy, eventually followed by radiotherapy, is the treatment modality most frequently applied, while the role of chemotherapy remains unclear. Several new cases of maxillary AC have been recently described in literature, making this pathology more frequent than previously considered; this is perhaps an indication of an increased diagnostic sensibility, rather than a real increase in the incidence of the disease itself.

    Monostotic fibrous dysplasia of the vertebra is a rare entity. A case of a 53-year-old lady who presented with an 8 months history of pain in the thoracic spine region with paraparesis is discussed. She had a history of papillary thyroid carcinoma and had undergone total thyroidectomy one year prior to her current problem. Magnetic resonance imaging revealed isolated osteolytic lesion over the posterior element of the T12 vertebra with narrowing of the spinal canal causing compression of the cord. The diagnosis of fibrous dysplasia was made histologically. Fibrous dysplasia rarely occurs in axial bones compared with peripheral bones. This case illustrates that osteolytic lesion of the vertebrae should be evaluated with detailed radiological and histopathological examination before an empirical diagnosis of spinal metastasis is made in an adult with a background history of primary malignancy well-known to spread to the bone.

    Background: Peritoneal tuberculosis accounts 1-2% of all forms of tuberculosis. Peritoneal tuberculosis is an important differential diagnosis for ovarian cancer in women with ascites, adnexal mass and elevated cancer antigen 125 (CA125) levels. We report a case of a 32- year -old woman with multiple miliary peritoneal deposits mimicking advanced ovarian carcinoma. Case Presentation: A 32-year-old drug addicted woman presented with menometrorrhagia, fever and shivering, ascites and pelvis mass. Ultrasonography revealed a 53×65 mm cyst in left ovary and ascites. Multiple miliary peritoneal deposits were observed during laparatomy without any mass, histologic examination confirmed tuberculosis of uterus, tubes, omentum, liver and external surfaces of small intestine. Finally, the patient recovered with anti-tuberculosis treatment. Conclusion: These findings highlight considering tuberculosis in the differential diagnosis of any patients with adnexal mass, ascitis and elevated serum CA125 even with negative cytology and bacteriology test results.

    Synchronous malignancies, including three or more tumours, are extremely rare. Herein, we present a case of a woman with a concurrent simultaneous endometrial, ovarian and fallopian tubal carcinoma with different histopathological characteristics. A 55-year-old postmenopausal woman with a diagnosis of endometrial adenocarcinoma by pipelle biopsy, underwent surgical staging. Final pathology result was reported as synchronous stage IA grade 2 endometrioid adenocarcinoma of the uterus, stage IA grade 2 mucinous adenocarcinoma of the right ovary and in situ serous cystadenocarcinoma of the right fallopian tube. In the postoperative period, patient followed without adjuvant therapy. To our knowledge, this a very rare case report in the literature of sychronous triple gynaecologic cancers including fallopian tube cancer and with the longest disease free survival time with over 39 months due to better prognosis than metastatic or advanced primitive diseases.

    Hashimoto's thyroiditis with thyroid cancer in childhood is not as common in the adult population. Hashimoto's thyroiditis is an autoimmune disease associated with autoantibodies, and the association between Hashimoto's thyroiditis and papillary carcinoma of the thyroid remains controversial. The present study reported a 15-year-old adolescent girl with the diagnosis of Hashimoto's thyroiditis with thyroid cancer. With the complexity of the clinical manifestations of Hashimoto's thyroiditis, it can be expressed as not only hyperthyroidism or hypothyroidism, but also normal thyroid function. The long-term treatment, and for children with thyroid cancer, early diagnosis is particularly difficult. In the present case, the diagnosis of Hashimoto's thyroiditis is primarily based on clinical manifestations, anti-thyroglobulin antibody and anti-thyroid microsomal antibody. The only diagnostic imaging ultrasound was negative. The present study discussed the possible reason and the identification of this unique case of Hashimoto's thyroiditis with thyroid cancer.

    Stewart-Treves syndrome is an angiosarcoma that occurs because of chronic lymphedema, which in most cases is a complication after mastectomy with axillary node dissection and postoperative radiation. Prognosis for this rare tumor is poor. The best therapy is early and radical excision. Chronic lymphedema seems to be an important pathogenic factor. We report a 59-year-old patient with chronic lymphedema and lymphangiosarcoma of the left upper limb who had a left modified radical mastectomy with axillary node dissection and postoperative radiation nine years ago. Additionally, the patient underwent a right modified radical mastectomy with axillary node dissection and postoperative radiation one year ago. In this report, we present a case of Stewart-Treves syndrome after the patient was operated for bilateral breast carcinoma, a review of literature, and principles of treatment.

    Squamous cell carcinoma (SCC) is the most common malignant tumor in the oral cavity, and it accounts for about 90% of all oral cancers. Several risk factors for oral SCC have been identified; however, SCC associated with odontogenic keratocysts have rarely been reported. The present study describes the case of a 36-year-old man with SCC of the right ramus of the mandible, which was initially diagnosed as a benign odontogenic cyst. He underwent enucleation at another hospital followed by segmental mandibulectomy and fibular free flap reconstruction at our institution. In this case, we introduce a patient with oral cancer associated with odontogenic cyst on the mandible and report a satisfactory outcome with wide resection and immediate free flap reconstruction.

    Male breast cancer is a rare malignant disease characterized by hormonal imbalance. Hepatocellular carcinoma (HCC) is the most common neoplasm of the liver, and is generally correlated with hepatitis B or C virus-related cirrhosis. While to our knowledge a case with these two malignant diseases in a same male patient in the concomitant period is an exceptional event, rarely reported in literature. In this report, we present a case in which a Chinese patient with hepatitis B developed a tumor mass that originated from segment V of the liver and presented with right breast nodules at the same time. Synchronous mastectomy and hepatectomy were performed, and standard endocrine therapy and chemotherapy as adjuvant treatment were therefore followed. The diverse histogenesis of the two kinds of cancers highlights the need for us to investigate any common physiopathogenetic elements. PMID:26617917

    Introduction: We describe the first known case of bilateral basaloid squamous cell carcinoma of the parotid gland, and we review existing literature. Case Presentation: A previously healthy, 70-year-old white man presented with a 2-cm enlarging mass in the tail of the right parotid gland. Magnetic resonance imaging and computed tomography showed ipsilateral pathologic adenopathy. Results of fine-needle aspiration revealed a high-grade malignancy with squamous features. The patient underwent a right total parotidectomy and modified radical neck dissection. Final pathologic findings revealed a basaloid squamous cell carcinoma. Four years after the initial resection, the patient presented with an enlarging left parotid mass. Findings of fine-needle aspiration and imaging were similar to those 4 years earlier. The patient received a left total parotidectomy and modified radical neck dissection. Postoperative radiation therapy was performed after each surgical intervention. He remains disease free at 4-year follow-up after the second mass was resected. Discussion: Squamous cell carcinoma with basaloid features is a rare and aggressive type of squamous cell carcinoma. To our knowledge, this is the first case report of bilateral parotid basaloid squamous cell carcinoma. PMID:28333602

    A population-based case-control study was conducted in Biella, which is located in northwestern Italy, to investigate the reported association between sinonasal carcinomas and woolen fabrics production. The study included 33 cases diagnosed during 1976-1988 (14 adenocarcinomas, 11 epidermoid carcinomas, 3 other specified carcinomas, 1 unspecified carcinoma, and 4 cases without histologic confirmation) and 131 controls. No association was found with smoking. As reported previously, excess risks were observed in wood and furniture workers (odds ratio [OR] = 4.4, 95% confidence interval [95% CI] = 1.41-13.4) and in the leather industry (OR = 3.5, 95% CI = 0.6-20.3). Odds ratios in the wood and furniture industry were 22.0 (95% CI = 4.4-124.0) for adenocarcinomas and 0.9 (95% CI = 0.4-8.3) for epidermoid carcinomas. No association was found with the woolen textile or garment industries (OR = 0.8, 95% CI = 0.2-2.8), nor with farming, construction, metal works, and transport. Odds ratios for the textile industry did not vary with length of exposure or histologic type. Power for detecting an odds ratio of 3.0 at the 95% level of significance was 40%.

    From 1970 to 1992, 31 pure ductal carcinoma in situ (DCIS) of the male breast treated in 19 French Regional Cancer Centres were reviewed. They represent 5% of all breast cancers treated in men in the same period. The median age was 58 years, but 6 patients were younger than 40 years. TNM classification (UICC, 1978) showed 12 T0 (discovered only by bloody nipple discharge), 10 T1, 5 T2 and four unclassified tumours (Tx). 11 patients (35.5%) had clinical gynecomastia, and three (10%) had a family history of breast cancer. 6 patients underwent lumpectomy, and 25 mastectomy. Axillary dissection was performed in 19 cases. 6 cases received postoperative irradiation. 15 out of 31 lesions were of the papillary subtype, pure or associated with a cribriform component. The size of the 12 measured lesions varied from 3 to 45 mm. All lymph nodes sampled were negative. With a median follow-up of 83 months, 4 patients (13%) presented a local relapse (LR), respectively, at 12, 27, 36 and 55 months. 3 of these patients had been initially treated by lumpectomy. In one case LR was still in situ, but already infiltrating in the 3 others. Radical salvage surgery was performed in 3 cases, but one patient developed metastases and died 30 months later. The last patient was treated by multiple local excisions and tamoxifen. One 43-year-old patient developed a contralateral DCIS and three others developed a metachronous cancer. The aetiology and risk factors of male breast cancer remain unknown. Gynecomastia, which implies an imbalance between androgen and oestrogen, may be a predisposing factor. As in women, DCIS in the male breast has a good prognosis. Total mastectomy without axillary dissection is the basic treatment. Frequently, the first symptom is a bloody nipple discharge. The age of occurrence is younger than for infiltrating carcinoma, suggesting that DCIS is the first step in the development of breast cancer.

    Sarcomatous transformation of chromophobe renal cell carcinoma (CRCC) is a well recognized phenomenon. Of the published cases with sarcomatous transformation of CRCC, none have shown liposarcomatous differentiation. Out of a cohort of 250 cases of CRCC, 19 (7.6%) showed sarcomatous differentiation. In one case (female, age 46 years), the sarcomatous component of the tumor displayed histological features of a pleomorphic liposar-coma. Light microscopic examination revealed a biphasic pattern with a chromophobe renal cell carcinoma(CRCC) and a high-grade sarcomatous component containing large pleomorphic lipoblasts. In several areas both components were intermingled. The conventional CRCC component showed classic histological features with calcifications, medium-sized polygonal cells arranged in solid-alveolar structures with raisinoid nuclei, pale-eosinophilic flocculent cytoplasm with perinuclear haloes. In addition, a microcystic-adenomatous component had luminal spaces filled with erythrocytes. The CRCC was positive with Hale's colloidal iron-stain whereas the sarcomatous component was negative. The CRCC component was diffusely positive for cytokeratin 7, parvalbumin and racemase but negative for cy-tokeratin 20, vimentin, CD10, carboanhydrase IX and S100-protein. The pleomorphic liposarcomatous component displayed immunereactivity for CD10, vimentin, racemase and focally for carboanhydrase IX. The proliferative activity (Mib-1/Ki-67) was 5% in the CRCC and 30% in the pleomorphic liposarcomatous component. No immunereactivity for MDM2 or CDK4 was detected.This is the first reported case of a sarcomatoid CRCC where the sarcomatous component displayed features of a pleomorphic liposarcoma. The patient died from widespread metastatic disease 12 months after nephrectomy. PMID:20606735

    Increasing evidence has suggested that human papillomaviruses (HPVs) are linked to a large subset of numerous malignant tumors, including mucosal squamous cell carcinoma (SCC); however, its involvement in cutaneous SCC has not fully been elucidated. Cutaneous SCC is the second most common type of skin cancer and is increasing in frequency every year. Since we have no satisfactory treatment for advanced SCC, it is important to provide a definitive diagnosis and appropriate therapeutic intervention at an early stage. Here, we present two cases of SCC arising in immunosuppressed patients. In these cases, we suspected the association between SCC and HPV infection histopathologically and succeeded in proving the presence of high-risk type HPV by PCR analysis (HPV 14 in case 1 and HPV 23 and 38 in case 2). Although it is unclear whether HPV actually induced SCC in our cases, our cases showed rapid progression comparing to typical courses of actinic keratosis (AK)/SCC. SCC and AK are common diseases; in daily practice, dermatologists examine many patients with immunosuppression of various causes. We should apply increased oncological vigilance to these patients to prevent an aggressive course of SCC/AK. PMID:26351427

    Pregnancy-associated breast cancer is the most common solid tumor in pregnancy after cervical carcinoma but still has a low incidence. It has been associated with a poor prognosis; though based on a limited number of retrospective case-control studies, some authors have reported no differences from that of non-pregnant patients. There is no consensus about the treatment; it requires an interdisciplinary approach and it is necessary to balance between the benefit for the mother and risk for the fetus. Each case requires an individual decision taking into account the stage of disease, patient preferences and gestational age. Above chemotherapy, it is only recommended after the first trimester of pregnancy and anthracyclin-based schemes have the higher evidence, but taxanes are also considered as an alternative in patients who do not respond to anthracyclines or its use is contraindicated. For the time being, there is a lack of data, and clinical decisions are based on small retrospective cohorts, case-control studies and case reports. We report two cases of patients being diagnosed with breast cancer while being pregnant and treated with surgery and chemotherapy, including anthracyclines, during the second and third trimester of pregnancy. In both reported cases, childbirth was induced before the 37th week of gestation and only one presented low birth weight with no more complications. The echocardiogram monitorization showed normal cardiac function in mothers and fetus.

    1997-01-01

    AIMS—In order to determine the clinicopathological features and optimum management of a series of patients with adenoid squamous cell carcinoma of the conjunctiva, all cases of squamous cell carcinoma (SCC) of the conjunctiva and cornea on file in the registry of the ophthalmic pathology at the Armed Forces Institute of Pathology were reviewed.
METHODS—On histopathological examination, a predominant adenoid or pseudoglandular pattern due to islands of neoplastic squamous or epidermoid cells surrounded by acantholytic cells was necessary for inclusion in the study. Histochemical and transmission electron microscopic studies (TEM) were performed. Clinical features of all the patients were extracted from the charts.
RESULTS—The anatomical location of the 14 tumours was corneoscleral limbus (seven patients) and bulbar conjunctiva (seven patients). Eight patients presented with inflammatory signs and irritation (red eye, tearing, foreign body sensation), while six patients developed a slowly growing, painless mass. Histochemical and TEM studies showed extracellular hyaluronic acid and no intracellular mucin. Of the two patients initially treated by enucleation, one was free of disease after 2 years while the second patient had recurrence in the socket and died of brain metastases despite wide orbital excision and radiotherapy. All five patients with recurrent tumours initially had irritated red eyes and two required enucleation. One such patient, after orbital exenteration and radiotherapy, died of unrelated disease.
CONCLUSION—The study demonstrates that adenoid SCC of the conjunctiva often presents with inflammatory signs. The tumour is locally aggressive and may metastasise and should, therefore, be histopathologically differentiated from the less aggressive conventional squamous cell carcinoma. Optimum treatment includes wide excision with documented histological clear margins of resection on permanent sections and frequent follow up.

Due to their histological resemblance to squamous cell carcinoma, the diagnostic and treatment standards applicable to the latter have so far also been applied to VC as a disease entity. Quite limited data are available including two case series of 5 or 11 patients. The present study reports on a single case treated by local endoscopic therapy and a series of 15 patients, 9 of whom received local endoscopic therapy. Methods The data for patients diagnosed with VC of the oesophagus who had been treated from January 1999 to May 2011 were analysed retrospectively. Results 15 patients with the diagnosis of oesophageal VC were included. The male-female ratio was 3:1. 9 of 11 pT1-VC patients presented with the cardinal symptom dysphagia or odynophagia. For the majority of the patients, the growth pattern is one of extensive superficial expansion showing a median length of 9 cm (range: 2-22 cm). Surprisingly, none of the VC patients showed lymph node or distant metastasis. 9 of 15 VC patients received local endoscopic therapy; 4 were treated with curative intent and 5 were treated palliatively. 3 patients underwent oesophageal resection, and definitive chemoradiotherapy was administered in a further 3 patients. One severe complication, consisting of a postoperative anastomotic insufficiency with a fatal outcome, occurred in this group of patients. Conclusion This is the largest published study describing patients diagnosed with VC of the oesophagus so far. The option of local endoscopic therapy and its results in 9 patients are reported for the first time. The superficial growth pattern of the tumour and the frequent absence of lymph node or distant metastasis suggest that endoscopic resection can be carried out as a diagnostic and/or therapeutic approach. Due to the rarity of this entity, the case numbers are unfortunately so limited that evidence-based recommendations are unlikely to become available

    Pediatric choroid plexus carcinomas (CPC) and adrenocortical carcinomas (ACC) are exceedingly rare tumors, each occurring at an annual rate of 0.3 cases per million children or less. Although both tumor types are associated with Li-Fraumeni Syndrome (LFS), the penetrance of germline TP53 mutations in CPC remains to be established. We report here a young boy without a family history of cancer who presented with CPC and subsequently ACC. Genetic testing revealed a novel de novo germline TP53 mutation (E285V). Neither tumor underwent loss of heterozygosity. Consistent with this observation, functional analyses demonstrated that E285V acts as a dominant-negative mutant that is defective in regulating target gene expression, growth suppression and apoptosis. These results further strengthen the association between germline TP53 mutations and childhood CPC, even when occurring in the absence of familial tumor susceptibility. PMID:18762572

    Odontogenic ghost cell carcinoma (OGCC), a malignant counterpart of the odontogenic ghost cell tumor (OGCT), with aggressive growth characteristics, is exceedingly rare. A painful swelling in the jaw with local paresthesia is the most common symptom. We described a case of 47-year Korean woman who had a rare central epithelial odontogenic ghost cell carcinoma which recurred at reconstructed fibular flap. Immunohistochemical differences between OGCT and OGCC analyzed using primary and recurred surgical specimen. On the basis of this case, the tumor started as an OGCT and transformed into OGCC with highly aggressive, rapidly growing, infiltrative tumors. Our findings suggest that some of the cytokines produced by ghost cells may play important roles in causing extensive bone resorption in the odontogenic ghost cell carcinoma. Wide local excision with histologically clean margins is the treatment mode of selection. Also, we recommend close long-term surveillance of OGCT because of high recurrence and potential for malignancy transformation.

    Background Mediastinal bronchogenic cyst (MBC) is the most common primary cystic lesion of the mediastinum. This study aimed to investigate the efficacy and safety of video-assisted thoracic surgery (VATS) compared with posterolateral thoracotomy (PLT) for the treatment of MBCs in a large series. Methods Patients with MBCs who underwent surgical resection between August 2005 and December 2015 were identified from the electronic database of the Department of Thoracic Surgery, West China Hospital. The patient demographic characteristics, intraoperative findings, postoperative outcomes and follow-up information were reviewed and analyzed. Results A total of 99 patients underwent cystectomy were enrolled for the present study. Of those patients, 65 underwent VATS cystectomy (VATS group) and 34 underwent PLT cystectomy (PLT group) during the same period. The VATS group had shorter operative time than the PLT group (108.77±47.81 vs. 144.62±55.16, P=0.001), less intraoperative blood loss (median 20 vs. 100 mL, P<0.001), and less pleural drainage of the first three days after surgery (median 240 vs. 400 mL, P=0.002). In addition, the length of postoperative hospital stay and duration of chest drainage for the VATS group was also shorter than those of the PLT group (4.94±2.01 vs. 8.64±5.52 days, P=0.001; 2.52±1.29 vs. 3.71±1.55 days, P<0.001, respectively). No statistical significance was revealed among the two groups with regard to the maximum diameter of the cysts, pleural atresia, incomplete resection, surgery-related complications, duration of intensive care unit stay, and postoperative complications. Conclusions Both VATS and PLT are reliable approaches for the surgical resection of MBCs. The VATS approach is superior to PLT with shorter operative time, shorter duration of chest drainage, shorter postoperative hospital stay, less intraoperative blood loss, and less pleural drainage of the first three days after surgery. We conclude that VATS should be the

    Primary squamous cell carcinoma of the colon is an extremely rare malignancy. A 48-year-old male visited our hospital for screening colonoscopy. Colonoscopic examination showed a 1 cm sized sessile polyp in the ascending colon. The patient underwent endoscopic mucosal resection (EMR) without any complication. The pathologic findings were compatible with squamous differentiation of tumor cells in inflammatory colonic mucosa. The tumor was confined to the mucosa and the margins of the excised tissue were found to be free of the tumor. There were no other primary sites and no distant metastases in the extensive evaluation using a whole body CT scan and PET-CT. Additional surgical resection was not done. Follow-up colonoscopy performed eight month later showed a whitish scar without evidence of local recurrence and follow-up PET-CT demonstrated no evidence of recurrence. Herein, we report a case of primary squamous cell carcinoma of the ascending colon presenting as a sessile polyp which was removed by EMR.

    We report the case of a primary mucinous carcinoma of the thyroid in a man of 74 who had a 4-cm nodule in the right lobe of the thyroid, with a solido-cystic appearance on ultrasound associated with lymph node metastases. On scintigraphy, the nodule was hot and not extinctive. The patient underwent total thyroidectomy with a ipsilateral right lymph node dissection. The immunohistochemical study showed the negativity of CK 7 and CK 20 and the positivity of thyroglobulin and TTF 1. Postoperatively the rate of blood thyroglobulin 3 months after surgery had collapsed to 0.17ng/ml. The evolution was marked by the appearance of pulmonary metastasis and the patient died 4 months after surgery. Histological study showed the presence of almas of neoplastic cells surrounded by large deposits of extracellular mucin. Primitive mucinous carcinoma of the thyroid is a rare tumor which differential diagnosis is established on the positive immunohistochemistry of thyroglobulin and TTF1 but negative for other markers.

    A man in his 70's visited the Department of Internal Medicine due to lumbago that had first appeared two months previously. Abdominal computed tomography showed a low-density area in the liver and swelling of lymph nodes surrounding the abdominal aorta. Four months later, he was hospitalized on an emergency basis in a urology ward in order to control bladder tamponade. Cystoscopy revealed massive blood clots and a papillary tumor at the left wall of the urinary bladder. He underwent transurethral resection of a bladder tumor, and the pathological diagnosis was a collision tumor between urothelial carcinoma (G2, pTa) and malignant lymphoma (B cell type). He underwent a liver biopsy soon thereafter, and the pathological diagnosis was malignant lymphoma (as for the one found in the urinary bladder). Bladder tamponade was repeated, which was relieved after one course of chemotherapy for malignant lymphoma. He underwent six courses of chemotherapy (THP-CO), and he was well without recurrence of either malignant lymphoma or urothelial carcinoma with 3 years' follow-up. To our knowledge, this is the 14th reported case of a collision tumor in the urinary tract.

    A 57-year-old white woman with metastases to lungs and liver from virilizing adrenocortical carcinoma (ACC) was treated with radical nephroadrenalectomy followed by oral mitotane 3 to 6 g/day for 5 months. She developed complete response and remained free of disease for more than 25 years. Here we present the case and review the literature. ACC is a rare tumor and may occur at any age. About 60% are functional tumors with hormonal secretions and clinical manifestations due to specific hormone secretions: Cushing's syndrome due to cortisone, virilizing tumor due to androgens, feminizing tumor due to estrogens, or hypertension due to aldosterone. Stage I and II disease is curable with surgery. Stage III and IV disease may benefit from mitotane orally with gradual adjustment of the dosage to a tolerable level. Plasma mitotane level at 14 to 20 g/L results in optimal response both in hormonal secretion and symptom control, as well as tumor regression. Addition of chemotherapy (streptozotocin or a combination of etoposide, cisplatin and doxorubicin) to mitotane also produced responses along with increased survival among responders. An international study has been started by randomizing between two of the above combinations by the Collaborative Group for Adrenocortical Carcinoma Treatment.

    Aims and Objectives. To evaluate the clinicopathologic features, response to cytoreductive surgery and adjuvant platinum-based chemotherapy with or without paclitaxel. Materials and Methods. A retrospective observational study of 8 women with a histopathologic diagnosis of primary fallopian tube carcinoma (PFTC) from January 2000 to February 2013. Results. 4/8 (50%) of the women were in the early stage and an intraoperative frozen section was 100% effective in identifying fallopian tube carcinoma and then a staging laparotomy was performed. All 4/8 cases in the early stage had received and responded to single agent carboplatin and all are alive without clinical, radiological, or biochemical evidence of recurrence at the end of 2 years and the longest survivor has completed 13 years. Primary optimal cytoreductive surgery was achievable in 3/4 (75%) in advanced disease. All showed response to adjuvant paclitaxel and carboplatin (T+C), but all had succumbed to the disease following recurrence with mean progression-free survival of 19 months (range 15–21 months) and mean overall survival of 27 months (range 22–36 months). Conclusion. The pivotal role played by a frozen section in diagnosing PFTC which is rare needs to be reemphasized, therefore justifying a primary staging laparotomy in an early stage. Prolonged survival observed in this group following an optimum tailored adjuvant single agent carboplatin is worth noting. PMID:24696653

    An 82-year-old Caucasian woman had a long-standing history of recurrent Paget’s disease of the right perianal region that was documented by multiple skin biopsies. Histological examination of a skin biopsy from an erythematous raised right perianal area revealed large rounded cells with ample pale staining cytoplasm scattered throughout the epidermis in multifocal nests and a flattened basal layer. A second lesion showed tongues of basaloid cells with peripheral palisading in continuity with the undersurface of the epidermis at multiple points. The individual tumor nests had cytoplasmic melanization and slit-like stromal separation. The tumor cells in the epidermis showed positive immunoreactivity for carcinoembryonic antigen while the basaloid cells were negative. A diagnosis of combined vulvar Paget’s disease and basal cell carcinoma of an infundibulocystic type was rendered. Concurrent involvement of the same area by Paget’s disease and Basal cell carcinoma (BCC) has been reported only once. Here we report a second case of BCC concurrent with vulvar Paget’s disease.

    Hepatocellular carcinoma (HCC) is the commonest primary malignant neoplasm of the liver in most countries with a notoriously poor prognosis. Variation in global incidence is well-recognized and the occurrence of HCC is linked to several established environmental, dietary, and lifestyle factors. HCC demonstrates morphological heterogeneity both within the same tumor and from patient to patient. Differing architectural patterns and cytological variants may be seen. Inclusion bodies are believed to represent organized structures of proteins which contribute to their pathogenesis and share several constituents like chaperones, p62, ubiquitin, and Valosin containing protein. The various hepatocyte cytoplasmic inclusions described in HCC include Mallory-Denk bodies (MDBs), hyaline bodies (HBs), glycogen, fat, fibrinogen, alpha 1 antitrypsin (AAT), and ground glass. MDBs are the most common inclusions seen in hepatocellular carcinomas. The two cases shared intracytoplasmic inclusions which are characterized by larger sizes and present in every section examined. These exhibited features of MDBs and HBs present in most tumor cells, further supporting close relationship. PMID:27818805

    Mucinous tubular and spindle cell carcinoma (MTSCC) is a recent entity introduced in the World Health Organization 2004 Classification. It is a tumour of low malignant potential. MTSCC is a subtype of renal cell carcinoma (RCC), which is characterized by a polymorphous histology, wherein the spindled epithelial cell is an inherent carcinomatous component. We report the case of a 57-year-old man presenting with loin pain and dragging sensation. Imaging revealed a large mass arising from the left kidney. Radical nephrectomy was performed, and histopathology revealed spindle cell elements of MTSCC with low-grade cytology, which occasionally blended with tubular structures in variable mucinous stroma admixed with spindle sarcomatoid cells with marked nuclear pleomorphism, associated with significant necrosis and mitoses of up to 5/10 high-power field. A final diagnosis of MTSCC along with high-grade areas consistent with sarcomatoid dedifferentiation was made. Sarcomatoid dedifferentiation has been well documented in various subtypes of RCC, and its presence signifies a worse prognosis in RCC.

    Serous endometrial intraepithelial carcinoma (serous EIC) arising in adenomyosis is rare. It may be underrecognized because of its deceiving morphology when embedded in the foci of adenomyosis. Although there is no connection to peritoneal cavity, some cases may be associated with extrauterine disease. It is currently unknown what the etiology for such a disease is. More studies are in need to elucidate the pathogenesis of such a grave malady. We report a series of 5 cases of serous EIC, which may arise in adenomyosis. The 5 cases are in 5 different patients or whom on histopathological examination of their hysterectomy specimens, the finding of adenomyosis involved with serous intraepithelial neoplasia was identified. The finding of interest was the presence of multifoci of adenomyosis; some of those foci were involved in serous EIC. In addition to EIC, lesions of endometrial glandular dysplasia were present in the foci of adenomyosis. To rule out the possibility of endometrial serous carcinoma (ESC) invading into the areas of the adenomyosis, all of the 5 uteri were extensively examined. Among the 5 uteri, the eutopic endometirum showed 1 invasive ESC, 2 serous EIC, and 2 benign resting endometrium without any cancer or precancerous lesions. In 1 uterus with ESC, we did not see any direct spatial connection between the invasive component of ESC and the areas of EIC in the foci of adenomyosis. In 2 uteri with serous EIC within the endometrial cavity, there was a distance of at least 0.5 cm between the lesions within the endometrial cavity and the serous EIC in adenomyosis. The remaining 2 uteri showed no evidence of endometrial malignancy in the endometrial cavity, whereas serous EIC was present only in areas of adenomyosis. Clinicopathologic data including characterized immunohistochemical stainings and p53 gene sequence analysis are presented and clinical significance is discussed.

    Background Primary tracheal tumors occur infrequently, accounting for less than 0.1% of all tumors. Adenoid cystic carcinoma (ACC) is the second most common type of malignancy of the trachea after squamous cell carcinoma (SCC). Little has been reported on the risk factors for tracheal ACC. The purpose of this study is to describe a case of tracheal ACC in a patient who had been exposed to rubber fumes, and to review the relationship between tracheal ACC and rubber fumes. Case report A 48-year-old man who had been experiencing aggravation of dyspnea for several months was diagnosed as having ACC of the trachea on the basis of a pathologic examination of a biopsy specimen obtained via laser microscopy-guided resection. The patient had been exposed to rubber fumes for 10 years at a tire manufacturing factory where he worked until ACC was diagnosed. His job involved preheating and changing rubber molds during the curing process. Conclusion ACC of both the trachea and the salivary glands show very similar patterns with regard to histopathology and epidemiology and are therefore assumed to have a common etiology. Rubber manufacturing is an occupational risk factor for the development of salivary gland tumors. Further, rubber fumes have been reported to be mutagenic. The exposure level to rubber fumes during the curing process at the patient’s workplace was estimated to be close to or higher than British Occupational Exposure Limits. Therefore, tracheal ACC in this case might have been influenced by occupational exposure to rubber fumes. PMID:24472110

    Introduction. In recent decades, a steady improvement in imaging diagnostics has been observed together with a rising adherence to regular clinical breast examinations. As a result, the detection of small clinically occult (nonpalpable) lesions has progressively increased. At present in our institution some 20% of the cases are treated when nonpalpable. The aim of the present study is to analyze the characteristics and prognosis of such tumors treated in a single institution. Methods. The analysis focused on 1,258 women who presented at the European Institute of Oncology with a primary clinically occult carcinoma between 2000 and 2006. All patients underwent radioguided occult lesion localization (ROLL), axillary dissection when appropriate, whole breast radiotherapy, or partial breast intraoperative irradiation and received tailored adjuvant systemic treatment. Results. Median age was 56 years. Imaging showed a breast nodule in half of the cases and a breast nodule accompanied by microcalcifications in 9%. Microcalcifications alone were present in 17.1% of the cases, whereas suspicious opacity, distortion, or thickening represented the remaining 24.6%. Most tumors were characterized by low proliferative rates (68.9%), positive estrogen receptors (92.3%), and non-overexpressed Her2/neu (91.3%). After a median follow-up of 60 months, we observed 19 local events (1.5%), 12 regional events (1%), and 20 distant metastases (1.6%). Five-year overall survival was 98.6%. Conclusions. Clinically occult (nonpalpable) carcinomas show very favorable prognostic features and high survival rates, showing the important role of modern imaging techniques. PMID:21147866

    Patient: Male, 61 Final Diagnosis: Pituitary metastasis from renal cell carcinoma Symptoms: Deterioration of visual acuity and field • persisting headache • excess thirst • polyuria Medication: — Clinical Procedure: Total body CT-scan • brain MRI • trans-sphenoidal endoscopical surgery • radiotherapy • anti-angiogenic therapy Specialty: Oncology Objective: Rare disease Background: Pituitary metastasis is uncommon, breast and lung cancers being the most frequent primary tumors. Renal cell carcinoma (RCC) is a rare cause of pituitary metastases, with only a few cases described to date. Case Report: We report a case of a 61-year-old man who presented with a progressive deterioration of visual acuity and field associated with a bitemporal hemianopsia. Two years ago, he underwent radical right nephrectomy for a clear cell RCC (ccRCC). The biological tests showed pan-hypopituitarism and diabetes insipidus. Brain MRI revealed a large sellar tumor lesion bilaterally infiltrating the cavernous sinuses, which was surgically resected. Histology confirmed a ccRCC pituitary metastasis. The patient received post-surgical radiotherapy. Considering the presence of concomitant extra-pituitary metastases, treatment with sunitinib was started, followed by several lines of therapy with axitinib, everolimus, and sorafenib because of tumor progression. The patient also presented with a pituitary tumor recurrence, which was treated by stereotaxic radiotherapy. He died five years after the initial diagnosis of RCC and 30 months after the diagnosis of the pituitary metastasis. Conclusions: There are no standardized treatment guidelines for management of pituitary metastases. Pituitary surgery plays a role in symptom palliation, and it does not have any relevant impact on survival. Exclusive radiotherapy or stereotaxic radiotherapy could be an alternative to surgery in patients whose general condition is poor or who have concomitant extra-pituitary metastases. PMID:28044054

    Medullary carcinoma is a recently recognized rare subtype of colorectal cancer resembling both poorly differentiated adenocarcinoma and neuroendocrine tumors. Medullary carcinoma most commonly presents in the proximal colon and can be differentiated from other right-sided malignant lesions by histology and immunochemical markers. We present here a rare case of an adult patient with rectal bleeding who was found to have an intussusception due to underlying medullary carcinoma of the splenic flexure. A 72-year-old woman presented to our GI clinic with rectal bleeding. Colonoscopy revealed a necrotic mass of the sigmoid colon, later determined by CT to be a colo-colonic intussusception at the level of the splenic flexure. Patient underwent diagnostic laparoscopy with findings of a large splenic flexure mass, which was resected and found to be medullary carcinoma of the colon. The tumor was poorly differentiated and exhibited microsatellite instability but was discovered at an early stage and thus did not require any adjuvant chemotherapy. Unlike most previously reported cases of medullary carcinoma, our patient presented with a left sided tumor. To our knowledge, this is the first report of a medullary colon cancer presenting with intussusception.

    Differentiated thyroid carcinoma (DTC) is a common malignancy. The general treatments are thyroidectomy of the affected lobe along with lymphadenectomy. However, bone metastasis is rare in DTC compared with other malignancies and the management of metastasis foci is still controversial. Here we present a case of follicular thyroid carcinoma with the 6th cervical vertebra body metastasis successfully treated by total thyroidectomy, cervical corpectomy, and internal fixation, followed by hormone replacement therapy and radioiodine therapy. Eleven additional patients diagnosed as thyroid carcinoma with bone metastasis collected from Chinese literature between January 1996 and December 2013 were also reviewed. The mean age of the 12 patients at presentation was (53.9±9.2) years (rang, 42-72 years) and the male to female ratio was 1:2. Nine cases received total/near-total thyroidectomy or lobectomy while the other three patients refused for personal reasons. The interventions for bone metastasis were one-stage operation (9/12), I(131) adjuvant therapy (3/12), chemotherapy (1/12), and no intervention (1/12). During the follow-up, two patients died of metastatic carcinoma recurrence, one died of multiple organ metastasis, and one with an unknown reason. We conclude that the management of thyroid carcinoma with bone metastasis needs multidisciplinary cooperation. Surgical resection is still the first choice for cure, while the combined one-stage operation on the primary and metastatic sites followed by hormone replacement therapy and radioiodine therapy is an applicable treatment.

  10. A unique bleeding-related complication of sorafenib, a tyrosine kinase inhibitor, in advanced hepatocellular carcinoma: a case report

    PubMed Central

    2014-01-01

    Introduction Sorafenib, a multikinase inhibitor as a standard of care for advanced hepatocellular carcinoma, may lead endothelial cells to an unstable state by blocking the signaling pathway of vascular endothelial growth factor receptor, which may result in the disruption of the architecture and integrity of the microvasculature, and eventually increase the risk of hemorrhage. Hemobilia is a relatively uncommon condition as a consequence of hepatocellular carcinoma and its risk factors remain uncertain. Case presentation Here we report a unique case of hemobilia occurring in a 55-year-old Korean man with hepatitis B virus-related hepatocellular carcinoma on Barcelona Clinic Liver Cancer advanced stage after seven days of treatment with sorafenib. He had received prior radiation therapy. Endoscopy revealed bleeding from the major duodenal papilla and endoscopic retrograde cholangiography revealed an amorphous filling defect throughout the common bile duct. Blood clots were removed by balloon sweeping and a nasobiliary drainage tube was placed. No further bleeding has been detected as of eight months after discontinuation of sorafenib. Conclusion Sorafenib may increase the risk of biliary bleeding in hepatocellular carcinoma patients who were primed with irradiation, by blocking the signaling pathway of the vascular endothelial growth factor receptor. Therefore, sorafenib should be used with caution in patients with advanced hepatocellular carcinoma, especially when combined with radiation therapy. PMID:24571585

    We herein described two cases of adenomyoepithelioma (AME) with carcinoma of the breast. Both of them were Japanese women, and they presented with a mass in their breast. Post-operative specimens revealed encapsulated and well-circumscribed tumors with local invasion, necrosis, cytological atypia, and a high mitotic rate. In immunohistochemistry, coincidentally with the loose adhesion pattern of myoepithelial cells in both cases, the intensities of E-cadherin and beta-catenin were much weaker in myoepithelial than luminal epithelial cells, with almost negative finding of beta-catenin in one case. We first found deletion of CDH1 and polysomy of CEP16 in myoepithelial cells by double color-fluorescence in situ hybridization. The two cases have been followed up for 5-8 years, and both remained free from local recurrence and distant metastases. We also presented an overview of 47 cases of AME with carcinoma in English-language literatures.

    The authors present the results of a quantitative study of carcinoma-in-situ and occult invasive cancers of the cervix. 40 separate carcinomata in-situ were measured and the limits of their topography precisely defined with reference to the external os on the one hand and the "last gland" on the other. It is known that this gland is situated at the site of the original junction between the cylindrical and pavement epithelia. It confirms that carcinoma-in-situ always (with few exceptions) develops upwards from the area of the original junction between the cylindrical and pavement epithelia, and its topography is higher than that of dysplasia especially when the two types of lesion are associated.

    A 55-year-old male presented with a rapidly expanding mass on the right side of the neck and progressive hoarseness. An electronic laryngoscopy and a computed tomography scan were performed, and the patient was subsequently diagnosed with tumors of the larynx and the thyroid gland. An en bloc near-total thyroidectomy combined with a total laryngectomy was performed. The final pathological analysis revealed a collision tumor that was derived from a laryngeal squamous cell carcinoma and a papillary thyroid carcinoma. Collision tumors of the head and neck are rare. The therapy for a collision tumor should consist of a combination of the treatments that are normally used for each focus. PMID:24260054

    Background Neuroendocrine carcinoma (NEC) of the esophagus is a rare and highly aggressive disease but the biological features are poorly understood. The objective of this study was to analyze the clinicopathological and immunohistochemical features of NEC of the esophagus. Methods Fourteen patients diagnosed with NEC of the esophagus from 1998 to 2013 were included in this study. Clinicopathologic features, therapeutic outcomes and immunohistochemical results were analyzed. Results Eleven out of 14 cases showed protruding or localized type with or without ulceration. Only three patients were negative for both lymph node and organ metastasis and seven cases were positive for metastases to distant organs and/or distant lymph nodes. Of the six patients with limited disease (LD), three patients were treated by surgery. Three patients with LD and seven patients with extensive disease (ED) were initially treated with chemotherapy, except for one who underwent concurrent chemo-radiotherapy due to passage disturbance. The median survival of patients with LD was 8.5 months, whereas that of patients with LD was 17 months. Among the 14 cases, 12 cases (83.3%), 13 cases (91.7%) and 12 cases (83.3%) showed positive immunostaining for choromogranin A, synaptophysin and CD56, respectively. Nine of 14 cases (64.2%) presented positive staining for c-kit and most (8/9, 88%) simultaneously showed p53 protein abnormality. Two cases were negative for c-kit and p53, and positive for CK20. Conclusion Consistent with previous reports, the prognosis of NEC of esophagus is dismal. From the results of immunohistochemical study, NEC of esophagus might be divided into two categories due to the staining positivity of c-kit and p53. This study provides new insight into the biology of NEC of the esophagus. PMID:28288180

    There is a group of low-grade papillomatous squamous cell carcinomas (SCC) of the penis, collectively designated as "verruciform," that are difficult to classify. A proposal of classification grouped these tumors in warty (condylomatous), verrucous, and papillary carcinomas. Papillary SCC, not otherwise specified is the third distinctive type of penile low-grade verruciform neoplasms. We are presenting clinicopathologic features of 35 cases from 2 institutions. All specimens were penectomies or circumcisions. Mean age was 57 years. Sites of involvement were glans alone in 18 cases (51%), glans, coronal sulcus and foreskin in 13 cases (37%), glans and sulcus in 3 cases (9%), and foreskin in 1 case (3%). Papillary carcinomas were large (mean 5.6 cm) exophytic low-grade squamous neoplasms with hyperkeratosis and papillomatosis. Papillae were variable in length and shape. The tip was straight, undulated, spiky, or blunt. There was no koilocytosis. The interface between tumor and stroma was characteristically jagged and a moderate stromal reaction was evident in most cases. The majority of the tumors (94%) showed a low-grade histology with focally present poorly differentiated areas in 6% of the cases. The mean thickness of the tumor was 9.4 mm. The most commonly invaded anatomic levels were the corpus spongiosum and/or dartos (77% cases). Corpus cavernosum was invaded in 8 cases (23%). Vascular and perineural invasion were unusual. Frequent associated lesions were squamous hyperplasia, differentiated penile intraepithelial neoplasia, and lichen sclerosus (74%, 46%, and 34%, respectively). Nodal metastases were identified in 3 of 12 patients with bilateral groin dissections. Of the 20 patients followed, 18 were either with no evidence of disease (15 cases) or died from unrelated causes (3 cases). One patient was alive with evidence of systemic metastases and 1 died from disseminated penile cancer 32 months after original penectomy. In conclusion, papillary carcinomas

    The purpose of this case series is to present the common features of intraosseous mucoepidermoid carcinoma (IMC) of the jaws in plain film and CT imaging. Two oral and maxillofacial radiologists reviewed and characterized the common features of four biopsy-proven cases of IMC in the jaws in plain film and CT imaging obtained from the files of the Department of Oral Radiology, Faculty of Dentistry, University of Toronto, Toronto, Canada. The common features are a well-defined sclerotic periphery, the presence of internal amorphous sclerotic bone and numerous small loculations, lack of septae bordering many of the loculations, and expansion and perforation of the outer cortical plate with extension into surrounding soft tissue. Other characteristics include tooth displacement and root resorption. The four cases of IMC reviewed have common imaging characteristics. All cases share some diagnostic imaging features with other multilocular-appearing entities of the jaws. However, the presence of amorphous sclerotic bone and malignant characteristics can be useful in the differential diagnosis.

    We report a case of biliary adenofibroma with an invasive carcinoma in a 71-year-old female who presented with bilateral upper abdominal pain. Imaging revealed a 6.3 cm heterogeneously enhancing mass in the left lateral segment of the liver. Histologically, the adenofibroma showed the characteristic components as previously described of biliary adenofibromata, namely, cystic and tubular structures lined by cuboidal to low columnar biliary type epithelium and a dense fibrous stroma composed of spindled cells. Intimately admixed with the adenofibroma was a distinct tumor composed of malignant clear cells which demonstrated stromal and vascular invasion. Although mitotic figures were inconspicuous, Ki67 was brisk and p53 demonstrated 25–50% positivity. Sections also showed a von Meyenberg complex located adjacent to the tumor. This case expands the understanding of this rare tumor and proves two important assertions from previous case reports. First, the presence of an associated von Meyenberg complex with similar morphology and immunohistochemical staining pattern suggests that biliary adenofibromata and von Meyenberg complexes may share related histogenesis. Second, biliary adenofibromata harbor malignant potential and may show malignant transformation. Furthermore, this case highlights the need for these rare tumors to be followed aggressively, as their biological behavior is poorly understood. PMID:26885426

    Introduction At the present time, the best possible choice for the local management of a multifocal hepatocellular carcinoma (HCC) developing on liver cirrhosis is multimodal treatment of the disease. Combined approach based on simultaneous radiofrequency ablation (RFA) together with limited surgical resection represents a valid choice of treatment. Case presentation A 75-year-old white female patient affected of HCV-associated cirrhosis in Child-Pugh’s functional class A5, developed a bifocal HCC. The patient had undergone a limited surgical resection together with simultaneous RFA, without intraoperative and postoperative surgical complications. At 36 months after surgery, still shows no sign of disease relapse. Conclusion This strategy directed at the management of multifocal HCC, may prove more useful for the reduction of surgical risk and post-operative progression of the liver cirrhosis than large-scale hepatectomy, since it presents no peri-operative mortality and a complication rate of less than 10%.

    A 79-year-old male presented with left ocular pain. Evisceration and silicone ball implantation were performed after a diagnosis of phthisis. He returned six weeks later because of left facial erythematous swelling, tenderness, mild fever, chills and cough. His condition was diagnosed as orbital cellulitis. Despite two weeks of empirical antibiotic therapy, the symptoms worsened. A subsequent orbital computed tomography scan revealed enhanced soft tissue infiltrations in his left orbit and eyelid. Biopsy showed a diffusely infiltrating tumor of signet ring cell cytology. A systemic evaluation revealed multiple bone metastases. Based on this evidence, the patient was diagnosed with a very rare case of histiocytoid variant eccrine sweat gland carcinoma with multiple bone metastases.

    While inguinal hernia is one of the most common diseases, metastatic cancer of an inguinal hernia sac is rare. We report a case of ascending colon cancer metastasized to an inguinal hernia sac. A 60-year-old man, who was undergone a right hemicolectomy for an ascending colon cancer, was pointed out a palpable inguinal mass at one year and eight months after the operation. He was diagnosed as inguinal hernia, and herniorrhaphy was performed. In the operation, a tumor of the inguinal hernia sac, which invaded to spermatic cord, could be found and was removed with right testis. Bassini's method was performed after the resection of the inguinal tumor. Histological examination revealed that the tumor was metastasis of colon carcinoma. Examination of the entire body showed no other metastasis. As for the advanced colon cancer, we need to mention the possibility of metastatic saccular tumor.

    Purpose To report a rare case of extreme leukocytosis and leukemoid reaction associated with lung sarcomatoid carcinoma (LSC) and increase people’s awareness of the disease. Patients and methods A 58-year-old male patient was diagnosed with LSC; however, after the end of the second course of chemotherapy, his white blood cells increased gradually without fever or use of medications such as granulocyte colony-stimulating factor and steroids. A bone marrow biopsy then confirmed it to be a leukemoid reaction. Results The patient died of multiple organ failure 2 months after being diagnosed with leukocytosis. Conclusion LSC associated with leukemoid reaction is very rare and the prognosis is poor. When a patient’s white blood cells are extremely elevated, we should think of the possible causes of the tumor itself and identify it with other diseases. However, more data and evidence are still needed to find an effective adjuvant therapy for these patients. PMID:28096688

    Irreversible electroporation (IRE) is a novel image-guided ablation technique that is increasingly used to treat locally advanced pancreatic carcinoma (LAPC). We describe a 67-year-old male patient with a 5 cm stage III pancreatic tumor who was referred for IRE. Because the ventral approach for electrode placement was considered dangerous due to vicinity of the tumor to collateral vessels and duodenum, the dorsal approach was chosen. Under CT-guidance, six electrodes were advanced in the tumor, approaching paravertebrally alongside the aorta and inferior vena cava. Ablation was performed without complications. This case describes that when ventral electrode placement for pancreatic IRE is impaired, the dorsal approach could be considered alternatively.

    Epidermodysplasia verruciformis (EV) is a very rare and chronic disease characterized by a susceptibility to cutaneous infections by a group of phylogenetically related human papillomavirus (HPV) types. We present here a 52-year-old man previously diagnosed and treated as squamous cell carcinoma but also found to have epidermodysplasia verruciformis lesions in association with Bowen's disease. The patient was effectively treated with a combination of interferon therapy (6 million units, twice a week) and topical imiquimod for Bowen's disease (five times a week). We conclude that topical imiquimod is very effective in the treatment of Bowen's disease and may be combined with systemic interferon therapy in rare cases with multiple vivid presentations of HPV infections.

    Adrenal cortical carcinoma (ACC) is a rare aggressive malignant tumor associated with a poor prognosis. Patients with ACC usually present with abnormal hormone secretion, tumor growth or encroachment on the surrounding viscera. An early diagnosis of ACC is considered challenging. The present study reports a case of ACC with tumor thrombus extension into the inferior vena cava and right atrium. A 33-year-old male patient exhibited symptoms of gynecomastia and abdominal distention, which were due to the abnormal hormone secretion levels and to the presence of a large mass in the right adrenal gland. An en bloc resection of the tumor was the selected treatment option. Extirpation of the tumor thrombus was performed by means of extracorporeal circulation. No signs of metastasis or recurrence were identified at the 1-month follow-up. PMID:27313728

    We report a case of axillary lymph node metastasis as a consequence of medullary thyroid carcinoma (MTC) in a 42-year-old man. On January 2009, the patient was referred to us for the management of right cervical lymph node enlargement. Total thyroidectomy was performed with right-sided functional neck dissection. Postoperative histopathology revealed MTC in the right lobe of the thyroid, with extrathyroidal extension and right-sided neck metastases. Multiple left cervical, mediastinal, and right axillary lymphadenopathies were detected at the third year follow-up exam. Left-sided functional neck dissection, axillary lymph node dissection, and mediastinal lymph node dissection were performed, and the pathologic outcomes revealed as the metastatic dissemination of MTC. After a disease-free term for 1 year, multiple metastatic lesions were detected in the patient. PMID:25785315

    Yttrium-90 microspheres constitute one of the most recent treatment options for hepatocellular carcinoma (HCC) in the setting of cirrhosis. As such, their spectrum of indication is not yet fully established. Herein, we have reported the case of a patient with HCC beyond the listing criteria for liver transplantation (OLT) who was treated preoperatively with selective transarterial chemoembolization and yttrium-90 microspheres. He was subsequently transplanted with a liver from an 81-year-old donor allocated through Eurotransplant as a "rescue offer." The posttransplant course was uneventful. Pathologic examination revealed a multifocal, well-differentiated pT2 tumor with no vascular invasion. The patient is currently alive and in good condition at 14 months posttransplant, with no evidence of tumor recurrence by a current computed tomography scan. This report provided encouraging information on the potential of yttrium-90 microspheres as a bridging option before OLT for multifocal HCC.

    Four feline renal cell carcinomas (RCCs) were examined using histopathological and immunohistochemical procedures. Specimens were classified by predominant histological pattern according to WHO criteria. A panel of antibodies including β-catenin, C-KIT, VEGF and VEGF-R2 and double immunostaining for vimentin/cytokeratin and for E-cadherin/CD10 was selected to characterize the tumors. Neoplasms were classified as tubular (3/4) and papillary (1/4). Neoplastic epithelial cells were cytokeratin, vimentin, E-cadherin, VEGF-R2 positive and C-KIT negative; 3 cases were β-catenin positive, whereas only 2 tumors were CD10 and VEGF positive. No correlation with histotype was evident. Our results confirm the low frequency of RCCs in cats and suggest a histological pattern similar to canine RCCs. In contrast, a peculiar immunohistochemical profile different from both canine and human RCCs is identified. PMID:26888581

    The incidence of all malignant tumours during pregnancy is extremely rare and esophageal carcinoma ranges from 0.07 to 0.1% of all malignant neoplasms. The physiological changes during pregnancy frequently mask the complaints and symptoms related to the disease. The physical and physiological clinical conditions limit the diagnostic approaches. Therefore, the stage of cancer at the time of diagnosis is usually advanced. The management with cancer surgery and chemotherapy regimens must be modified in pregnant women in order to minimize fetal and maternal risks. Here, we report a very rare case of metastatic esophagus cancer in a 39-year-old woman with 28 weeks of pregnancy and aim to show the ultrasound (USG) and magnetic resonance imaging (MRI) findings with treatment and follow up management.

    'Clown nose' (CN) is the common medical term referring to a reddish-brown bulge involving the tip of the nose, reminding of a clown's fake red nose. Reports about these tumours are scarce. Most reports refer to metastatic skin manifestation of systemic malignancies: this condition has been rarely described as a primary skin neoplasm. We report a case of a 31-year-old patient with a giant cutaneous squamous cell carcinoma of the nose which evolved into a CN. After ruling out genetic or immune risk factors, the patient was treated with surgical excision of the lesion and local reconstruction with good aesthetic outcome and no recurrence over a 2-year follow-up.

    Clinically available targeted agents to treat advanced renal cell carcinoma (RCC) include sunitinib, sorafenib and temsirolimus. Sorafenib and sunitinib have been associated with bleeding in selected trials, but clinical and endoscopic characteristics of gastrointestinal bleeding are not well described. Herein, we report four cases of advanced RCC in which endoscopic hemostasis effectively resolved high-grade, life-threatening gastrointestinal bleeding that occurred during targeted therapy. Although stomatitis and mucositis have occurred during targeted therapies, life-threatening gastrointestinal bleeding is less common. In these four patients, the origins of gastrointestinal bleeding were identified, and complete endoscopic hemostasis was achieved. Endoscopies revealed variable characteristics including angiodysplasia, multiple gastric ulcers and oozing bleeding of the normal mucosa. Although the most effective diagnostic and treatment strategies are disputed, endoscopic examinations are best performed before starting targeted therapies. Additionally, these patients should be monitored even for rare life-threatening events. PMID:26722259

    A case of radionecrosis of sphenoid and temporal bones is reported. The patient received a combination of surgery, radiotherapy, and chemotherapy for his left maxillary sinus carcinoma. After the combined therapy, necrosis accompanying inflammation developed in the maxillary and temporal regions. Excision of the necrotic tissues was done, and the left ascending ramus of the mandible was resected because of persistent tumor mass at the left infratemporal fossa. Although the excision wound of the maxilla healed by epithelialization, an area of nonvital bone remained exposed in the temporal region, where progressive osteonecrosis with infection led to breakdown of the skin. The necrotic bones of the zygomatic arch and the sphenotemporal sutural region became visible through the skin defect, and computerized tomography scan revealed bone necrosis involving the inferolateral area and the base of the skull. Excision of the necrotic bone and reconstruction with sternocleidomastoid myocutaneous flap were performed.

    Keratitis-ichthyosis-deafness (KID) syndrome is a rare form of ectodermal dysplasia with significant visual and auditory impairment. Pathogenesis involves a mutation in the GJB2 gene, which encodes connexin-26, a protein in the epithelial gap junctions thought to be involved in the differentiation of ectodermally derived tissues. Affected patients are also at increased risk for the epithelial malignancies. To our knowledge, nearly 100 cases of KID syndrome, including 19 with squamous cell carcinoma (SCC) complications, have been reported worldwide. We report here a patient with KID syndrome who developed an ulcerative oral lesion causing him significant discomfort; he was subsequently diagnosed with oral SCC. We review the clinical presentation and symptomatology, including those affecting the oral cavity for this syndrome and highlight the importance of multidisciplinary collaboration and life-long screening aimed at prevention of the evolving complications.

    Hepatitis C infection is associated with the development of hepatocellular carcinoma, and progress has been made in a number of areas. Transgenic mice lines expressing the hepatitis C core protein develop hepatic steatosis, adenomas, and hepatocellular carcinomas, with no significant hepatitis or fibrosis. This implies that hepatitis C can lead directly to malignant transformation. A new lesion, irregular regeneration, has been described in chronic hepatitis C infection and is associated with a 15-fold increase in the relative risk of developing hepatocellular carcinoma. A minority of patients with hepatitis C-related hepatocellular carcinoma have intense lymphocytic infiltration of the cancer, a feature associated with a better prognosis. Several studies have confirmed the association between large cell dysplasia and hepatocellular carcinoma. However, large cell dysplasia may not be a premalignant lesion and instead may be a marker for premalignant alterations elsewhere in the liver. Oral contraceptives previously have been linked to an increased risk of hepatocellular carcinoma. A large multicenter European case-control study has shown minimal increased risk of hepatocellular carcinoma with use of steroidal contraception. Tamoxifen had shown promise in the management of advanced hepatocellular carcinoma. However, a randomized placebo-controlled study of 477 patients with hepatocellular carcinoma found no benefit from tamoxifen. In a preliminary study, however, octreotide has shown improved survival and quality of life in patients with advanced hepatocellular carcinoma. Finally, interferon treatment continues to be linked to a reduced risk of hepatocellular carcinoma in patients with hepatitis C. These studies generally are not randomized, and a randomized prospective study is required to address this issue.

    Patients treated with radiation have an increased risk of developing second cancers, of which carcinomas, sarcomas, and hematological malignancies have most commonly been reported. Neuroendocrine carcinomas (NEC) are rarely reported in patients previously treated with radiation. Two patients, who had successfully undergone chemoradiotherapy for head and neck cancers at our institution, developed secondary NEC within the radiation field more than five years after the treatment. Both patients underwent curative-intent treatment of secondary malignancies, one with chemotherapy, radiation and surgery (Case 1) and the other with chemotherapy and surgery (Case 2). Both had no evidence of disease at a short follow-up of twelve months (Case 1), and three months (Case 2) after treatment. NEC can develop post-radiotherapy; a multidisciplinary approach is necessary to successfully treat these patients. PMID:27909635

    Sclerosing mucoepidermoid carcinoma with eosinophilia (SMECE) was first described by Chan et al in 1991. It is characterized by nest or strands of epidermoid tumor cells with squamous differentiation, rare mucous cells, prominent sclerotic stroma, eosinophilic and lymphoplasmacytic infiltration, and a background of chronic lymphocytic thyroiditis in the non-neoplastic thyroid gland. It is important to recognize SMECE of thyroid and differentiate it from squamous cell carcinoma or other neoplasms with squamous differentiation/metaplasia. In published cases, the SMECE of thyroid gland predominantly occurs in women. We report a case of SMECE of thyroid in a 45-year-old male patient. All cases in male patients were Caucasian described in English literature, and our case is the first one in Asian.

    We report the case of a patient who had renal cell carcinoma with high everolimus blood concentrations and hyperglycemia due to everolimus-induced hepatic dysfunction. A 74-year-old man who underwent right nephrectomy for renal cell carcinoma was administered everolimus for multiple lung metastases. Everolimus caused grade 3 hepatic dysfunction and hyperglycemia; hence, high blood levels of everolimus were observed. Although the patient was re-administrated everolimus after recovering from hepatic dysfunction, hepatic function test values worsened again. Everolimus was discontinued before its blood concentration increased, and the patient was switched to axitinib treatment. Therefore, the measurement of everolimus blood level is considered useful for the management of adverse events in renal cell carcinoma.

    Pilomatrix carcinoma is an extremely rare skin tumor derived from basaloid cells in the hair follicles; it often exhibits locally aggressive behavior with a tendency toward local recurrence. The average age of occurrence is 45 years, and there appears to be a male to female incidence ratio of 4:1. Although pilomatrix carcinomas are predominantly identified in the neck and scalp, there are studies in the literature reporting other tumor development sites, including the upper extremities, torso and popliteal fossa. If diagnosed at an early stage, this malignant tumor is generally treated with wide surgical resection. However, for the advanced-stage tumors, there are no standard treatment procedures known to produce good results. The current study presents the case of a 76-year-old male with pilomatrix carcinoma originating from the scalp with metastases to the lung. The patient had a rapid and complete clinical response following an oral combination chemotherapy regimen of cyclophosphamide and etoposide. PMID:24932268

    Neuroendocrine tumors are composed by a heterogeneous group of tumors with a wide range of morphologic, functional, and behavioral characteristics. These tumors are generally slow growing and behave in an indolent fashion. However, they have the potential to spread, especially for poorly differentiated neuroendocrine carcinomas, and when they do, they can be very aggressive, with high propensity for distant metastases, and difficult to treat with current modalities. As poorly differentiated neuroendocrine carcinomas rarely occur in extrapulmonary sites, to the best of our knowledge, this is the first case report of a poorly differentiated duodenal neuroendocrine carcinoma with diffuse liver and bone metastases as the primary manifestation. Despite receiving a trial of chemotherapeutic regimen, the patient had progressive intrahepatic cholestasis and died of subacute hepatic failure.

    Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare malignant neoplasm that has an exquisitely exclusive affection to the jawbone. It is defined as squamous cell carcinoma arising within the jaw and developing from residual odontogenic epithelium or from a preexisting odontogenic cyst or tumor. The solid-type of this tumor is a central jaw carcinoma arising de novo and has no initial connection with the oral mucosa. Herein, we report a case of solid-type PIOSCC involving the mandible in a 37-year-old male patient elucidating its histopathological and imaging findings. The patient underwent surgical resection followed by post-operative adjuvant radiotherapy. The close 2-year follow up of the patient revealed neither locoregional nor distant metastasis.

    Sarcomatoid transitional cell carcinoma is a rare entity, in which a malignant, overtly epithelial component coexists with areas having a sarcoma-like appearance. Histological distinction of sarcomatoid carcinomas from carcinosarcomas is often difficult and immunohistochemistry is a helpful diagnostic adjunct in the correct diagnosis. In the present report, we describe an uncommon case of sarcomatoid transitional cell carcinoma of the renal pelvis, associated with giant cell tumor-like features. Immunoperoxidase staining for cytokeratin was positive in spindle cell component, indicating an epithelial origin. The carcinomatous component showed a diffuse membranous reactivity for E-cadherin, whereas the reactivity was sporadic and weaker in the sarcomatoid component, suggesting that the decrease of E-cadherin expression might be associated with the acquisition of sarcomatous morphology. Osteoclast-like multinucleated giant cells were positive for CD68 and negative for p53 oncoprotein, suggesting that they represent a non-neoplastic component that is reactively induced in the tumor stroma.

    Primary neuroendocrine carcinoma of breast (NECB) is a very rare tumor; the World Health Organization(WHO) subcategorized these tumors into 3 major histologic subtypes: solid, small cell carcinoma (SMCC), and large cell NE carcinoma. The SMCC subtype is the least common and most aggressive and has been reported to be as aggressive as its pulmonary counterpart. SMCC is usually confirmed based on clinical, pathologic,and imaging studies. Local disease is usually managed in a fashion similar to that of the usual ductal breast cancer; in the metastatic SMCC setting, regimens that are implemented in small cell lung cancer are usually attempted, according to case reports and published small case series. Hormone receptors can be expressed in more than 90% of the solid tumor subtype; however its expression is manifested in about 50% of cases of SMCC. Although hormonal therapy can be used successfully to treat the usual metastatic ductal breast cancer,its utility in metastatic SMCC has not been reported. We report an impressive response to hormonal therapy in a patient with late relapse of breast carcinoma with a metastatic SMCC subtype that expressed hormone receptors. The response to hormonal therapy was sustained for about 12 months. The response to hormonal therapy is definitely an interesting finding that, to our knowledge, has not been described before in the setting of metastatic SMCC. We suggest considering adding hormonal therapy to the treatment pipeline for primary SMCC of the breast that express hormone receptors.

    Incense burning is a powerful producer of carcinogens and has been considered as a risk factor for nasopharyngeal carcinoma (NPC). We conducted a case-control study and case-only analyses to investigate the effect of incense burning and its interaction with genetic background on NPC risk among Hong Kong Chinese. Between June 2010 and December 2012, we recruited 352 incident cases of NPC and 410 controls. We collected information on lifelong practice of domestic incense burning via interviews and genotyped 80 single nucleotide polymorphisms (SNPs) in DNA repair genes. We observed an increased NPC risk associated with daily burning in women [Adjusted OR = 2.49, 95% confidence interval (CI): 1.33, 4.66] but not in men. The adjusted OR for daily burning with poor ventilation was 2.08 (95% CI: 1.02, 4.24), while that with good ventilation was 1.35 (95% CI: 0.92, 1.98). Interactions between 2 SNPs (rs2074517 and rs4771436) and incense burning were significantly associated with NPC risk and tended to have a SNP exposure-response effect. Evidence for gene-environment interactions supported the knowledge that NPC is a multi-factorial disease resulting from the joint effects of environmental exposures and inherited susceptibility.

    AIM: To characterize the clinical features of hepatocellular carcinoma (HCC) associated with autoimmune liver disease, we critically evaluated the literature on HCC associated with autoimmune hepatitis (AIH) and primary biliary cirrhosis (PBC). METHODS: A systematic review of the literature was conducted using the Japana Centra Revuo Medicina database which produced 38 cases of HCC with AIH (AIH-series) and 50 cases of HCC with PBC (PBC-series). We compared the clinical features of these two sets of patients with the general Japanese HCC population. RESULTS: On average, HCC was more common in men than in women with AIH or PBC. While many patients underwent chemolipiodolization (CL) or transcatheter arterial embolization (TAE) (AIH-series: P = 0.048 (vs operation), P = 0.018 (vs RFA, PEIT); PBC-series: P = 0.027 (vs RFA, PEIT), others refused therapeutic interventions [AIH-series: P = 0.038 (vs RFA, PEIT); PBC-series: P = 0.003 (vs RFA, PEIT)]. Liver failure was the primary cause of death among patients in this study, followed by tumor rupture. The survival interval between diagnosis and death was fairly short, averaging 14 ± 12 mo in AIH patients and 8.4 ± 14 mo in PBC patients. CONCLUSION: We demonstrated common clinical features among Japanese cases of HCC arising from AIH and PBC. PMID:19132775

    Adrenocortical carcinoma (ACC) is an uncommon and aggressive cancer occurring more frequently in women; local or distant recurrences occur in 80% of cases, typically within 1 year after curative resection. Liver is the preferred metastatic site. Herein, we report the case of a unique liver metastasis from ACC occurring 23 years after the curative prior tumor surgery. A 45-year-old woman was operated in 1991 for adrenocortical stage II without microvascular involvement or capsular infiltration. At that time, no adjuvant treatment was indicated. The initial surgery consisted on a left adrenalectomy with contemporaneous left nephrectomy and regional lymphadenectomy. Five years after surgery, the patient was considered cured. However, 23 years later, the patient presented an atypical right subcostal pain. A 4 cm liver ACC metastasis involving the segment 4 and initially diagnosed as a hemangioma was discovered. A curative resection of the segment 4 was performed. Final pathological examination confirmed the diagnosis of ACC metastasis with a complete R0 resection; no lymph node metastases were observed. This case is the latest metachronous ACC metastasis ever reported in literature. To date, the patient is alive with no signs of recurrence after a post-surgical follow-up of 13 months. PMID:27275470

    The treatment of hepatocellular carcinoma (HCC) is difficult due to the underlying cirrhosis which has its own influence on therapeutic issues. An inquiry was performed in centres with specialized multidisciplinary team meetings dedicated to HCC (HCC-MTM) or in centres with non-specialized (digestive oncology or general oncology) multidisciplinary team meetings (NS-MTM). The number of cases of HCCs taken in charge yearly was significantly higher in HCC-MTM than in NS-MTM (p=0,0014). Interventional radiologists and transplant surgeons were more frequently implied in HCC-MTM than in NS-MTM (respectively p=0,009 and p=0,02). On site availability of every treatment of HCC was higher in RCP-MTM than in NS-MTM (p=0,015). There were no inclusion in clinical trials in 40.5 % of NS-MTM versus only 17.6 % of HCC-MTM (p=0,0086). In three clinical cases out of seven there were discrepancies between the therapeutic options of HCC-MTM and NS-MTM. In all three cases, the treatment offered to the patient by HCC-MTM was more consistent with clinical standards. These results prompt to perform more studies on the quality of management of patients with HCCs by MTMs.

    We present three papillary thyroid carcinoma PTC patients with brain metastases who are unusual in many aspects. The first case is a unique 3mm papillary thyroid microcarcinoma (PTMC) patient with metastases to the cerebrum and lung. The solitary cerebral lesion was identified by iodine-131 whole- body scan ((131)I-WBS) and (131)I single photon emission tomography/computed tomography (SPET/CT). Almost complete response achieved after radiosurgery. The second case is a unique PTC patient with coexistent (131)I-negative cerebrum, adrenal gland and ilium metastases, which were identified by (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) and magnetic resonance imaging (MRI). Partial response achieved after radiosurgery. The third case is a patient with an incident solitary cystic cerebellar mass as a primary presentation of follicular variant of PTC and absent other distant metastases. In conclusion, widespread metastases from small PTMC may occur. Concomitant brain and adrenal metastases may occur in a same PTC patient. Brain metastasis may present as a cystic lesion.

    Macrofollicular variant of papillary thyroid carcinoma (MFVPTC) is one of the rarest histologic types of papillary carcinoma. This tumor may mimic an adenomatoid/colloid nodule or follicular neoplasm (macrofollicular type) both on histology and cytology. There are very few articles describing the cytologic features of MFVPTC. We report the cytologic findings of two surgically confirmed MFVPTC. The first case showed abundant thin colloid with moderate amount of follicular cells arranged in a honeycombed and syncytial pattern. Some but not all the follicular cells showed enlarged round to ovoid nuclei, overlapping nuclei, few nuclear grooves and rare intranuclear inclusions. The second case showed abundant thin colloid and predominantly benign appearing follicular cells with few overlapping nuclei, enlarged round to ovoid nuclei and rare nuclear grooves. No intranuclear inclusions were identified. A review of the literature was done and the cytologic findings of MFVPTC including our two cases were tabulated. The cytologic findings showed moderate to abundant thin with focally thick colloid in 75% of cases and sheet like arrangement of follicular cells in 76%. Although nuclear features such as chromatin clearing, overlapping and grooves were present in majority of cases, the quantity varied from rare to focal. Small to prominent nucleoli were present in all of the evaluable cases. Intranuclear inclusions were seen only in 45% of patients. Hence, the cytologic features of macrofollicular variant of papillary carcinoma though present can be subtle and intranuclear inclusions may not be present always. PMID:24082912

    Mammary analogue secretory carcinoma (MASC) is a recently described low-grade carcinoma with morphologic and genetic similarity, including ETV6-NTRK3 fusion, to secretory carcinoma of the breast. ETV6 is frequently involved in other epithelial and nonepithelial tumors, and many fusion partners of ETV6 have been reported. In the present study, 14 Japanese MASC cases were clinicopathologically and molecularly analyzed. The median age of the patients was 39 years, and the male:female ratio was 6:8. All cases showed histopathologic findings compatible with those previously described for MASC and harbored an ETV6 split as visualized by fluorescence in situ hybridization. Two cases showed thick fibrous septa and invasive features including vascular or perineural tumor involvement, findings that are rare in MASC. In addition, in these 2 cases, non-NTRK3 genes appeared to fuse with ETV6 (ETV6-X fusion). NTRK1 and NTRK2, both members of the NTRK family, were not involved. Of the 14 MASC cases, the ETV6-NTRK3 fusion transcript was positive in 6 cases, and the relative expression level of the ETV6-NTRK3 fusion transcript was variable, ranging from 1 to 5.8. Results of the present study of MASC suggest that (1) ETV6 occasionally fuses with unknown non-NTRK3 genes, (2) ETV6-X cases might have an invasive histology, (3) for molecular diagnosis of MASC, fluorescence in situ hybridization to detect ETV6 splits is the method of choice, and (4) the expression level of the ETV6-NTRK3 fusion transcript is considerably variable. These findings provide a novel insight into the oncogenesis, histopathology, diagnosis, treatment, and prognosis of this newly recognized carcinoma.

    Human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma has been identified as a distinct entity within squamous cell carcinoma of the head and neck. In contrast to carcinomas associated with alcohol and/or tobacco, this subtype occurs at younger age, with frequent absence of classic risk factors, correlation with oral sexual habits, strong predilection for the palatial tonsils and the base of the tongue (lingual tonsils), basaloid or lymphoepithelial differentiation, higher degree of radiosensitivity, and overall better survival. We report two cases of lymph node, metastatic, poorly differentiated squamous cell carcinoma that were positive by immunohistochemistry for p16 with detection of HPV-16 and HPV-45 by PCR.

    This study was carried out to clarify the presentation, treatment options, and prognosis of renal cell carcinoma (RCC) metastasis to the bladder in which we do not yet have a comprehensive understanding. A systematic Medline, Web of Science, Embase, Google, and Ichushi Web search was performed to identify articles describing RCC metastasis to the bladder. The final cohort included 65 patients. The majority (75%) experienced gross hematuria at the point of diagnosis of RCC. RCC metastasis to the bladder occurred both synchronously (23%) and metachronously (77%), and the median time for metachronous bladder metastasis following the diagnosis of RCC was 33 months. Of the 58 patients whose metastatic data were available, 36 (62%) had metastasis to the bladder only, while 22 (38%) had additional sites of metastasis. On pathology, clear cell carcinoma was the most common histology (92%) and all bladder tumors were consistent with RCC metastasis; the median tumor size was 2.1 cm, and two-thirds of cases were superficial (non-muscle invasive) disease. The 2-year cancer-specific survival rate in patients with solitary bladder metastasis was 71.1%, which was significantly higher than in patients with additional distant metastasis (25.8%, p = 0.007). Regarding the interval after the diagnosis of primary RCC, the 2-year cancer-specific survival rate in patients who experienced bladder metastasis after more than a 1 year follow-up was 58.4%, compared to 34.6% in their counterparts (p = 0.063). A curative resection may provide a good possibility of long-term survival, particularly in those with a solitary bladder metastasis and/or a long interval after nephrectomy.

    Lichenoid reactions represent a family of lesions with different etiologic factors and a common clinical and histologic ap-pearance. Lichen planus is included with lichenoid reactions and is a relatively common chronic mucocutaneous disorder. The most important complication of lichenoid reactions is the possibility of malignant transformation. That is why it has been considered a precancerous condition. Although the malignant transformation rate varies widely in the literature, from 0.4 to 6.5 percent, in most studies it does not exceed 1%. The aim of this paper is to report a rare case of squamous cell car-cinoma (SCC) arising within an oral lichenoid lesion in a 17-year-old woman, where SCC is very uncommon. The patient did not have any risk factors and was healthy. The lesion was located on the border of the tongue. In view of thecommon occurrence of OLP (oral lichen planus) and the unresolved issues regarding its premalignant potential, this case report illus-trates the need for histologic confirmation and a close follow-up of clinical lesions with lichenoid features.

    We conducted a case-control study of nasopharyngeal carcinoma (NPC) in Tunisia, on diet, dietary patterns and life style, the characteristics of which had been defined by an anthropological study. Eighty incident cases, diagnosed in Tunisia between November 1986 and November 1987, were each matched for sex, age and place of residence to 2 controls. The subjects were asked for dietary data referring to the year preceding the diagnosis of NPC and, with help of their families, during childhood and after weaning. After adjustment for an empirical living conditions score, the following food items were found to be associated with an increased risk for NPC: preserved spiced meat (quaddid), basic stewing preparation (mixture of red and black pepper, garlic, oil, caraway and coriander), and harissa (red pepper, olive oil, garlic, caraway, salt) taken with bread as a snack during childhood and youth. Moreover, subjects who had been directly weaned from mother's milk on to an adult diet were found to be at higher risk for NPC.

    Multiple myeloma (MM) is a plasma-cell malignancy leading to a significant life-expectancy shortening. Lenalidomide is an oral immunomodulatory drug (IMiD) approved in the United States for patients with MM. Although the introduction of lenalidomide combined with dexamethasone (Len/Dex) has improved the outcome of patients with relapsed/refractory multiple myeloma (RRMM), it is a common knowledge that lenalidomide has been linked to the development of secondary primary malignancies in the MM patients, especially in those who use lenalidomide as a maintenance therapy. In the published literature, these are also many cases reported by clinicians in different secondary primary malignancies after the diagnosis of MM treated with lenalidomide. In this present article, we provided our patient who was identified nasopharyngeal carcinoma (NPC) 46 months after the diagnosis of MM and 21 months after lenalidomide treatment. To the best of our knowledge, this is the first case report related to the occurrence of NPC in a patient with MM after treatment by lenalidomide. Although it is not very sure that the incidence of NPC was associated with the use of lenalidomide, we clinicians should pay adequate attention to this phenomenon in the clinical processing. And much more cooperative studies of large numbers of MM patients are needed to evaluate a possible association between lenalidomide and NPC. PMID:26823839

    A 69-year-old woman was admitted to a nearby clinic complaining of abdominal pain. Abdominal CT showed a 10 cm diameter huge cystic lesion in the body and tail of the pancreas. The patient was referred to our institution for treatment. Endoscopic ultrasonography (EUS) revealed a cystic mass with a solid lesion. Endoscopic retrograde pancreatography(ERP) demonstrated mucous at the opening of the papilla of Vater and dilatation of the pancreatic duct with a solid nodule. Contrast radiography revealed a fistula from the tumor to the jejunum. A biopsy specimen from the lesion showed adenocarcinoma. Intraoperative findings showed a tumor occupying the pancreas body and tail with suspected invasion to the stomach, jejunum, and transverse colon. We performed distal pancreatectomy with partial resection of stomach, jejunum, and colon. Pathological findings showed an invasive type of IPMC, with invasion to the subserosal layer of the stomach and colon and the mucous layer of the jejunum. While IPMC is recognized as a slow growing malignancy, some cases of invasive carcinoma with fistulation into adjacent organs have been reported. To our knowledge, a case of IPMC penetrating to 3 adjacent organs is rare.

    AIM: To study clinical outcomes and management of lymph nodes extrapulmonary small cell carcinoma (LNEPSCC). METHODS: Herein, we perform a systematic search of published literature in the PubMed and EMBASE databases for studies describing LNEPSCC. For uniformity of reporting, LNEPSCC was staged as limited if it involved either single lymph node station or if surgery with curative intent had been undertaken. The disease was staged extensive if it involved two or more lymph node regions. RESULTS: The systematic literature review yielded eight descriptions (n = 14) involving cervical, submandibular and inguinal lymph nodes. Eleven (64.7%) patients had limited disease (LD) and six (35.3%) had extensive disease (ED) at presentation. Chemotherapy (n = 6, 35.3%) or surgery (n = 4, 23.5%) were the most common form of treatment given to these patients. Complete response was achieved in 12 (70.6%) of the patients. Median (interquartile range) progression free survival and overall survival was 15 (7-42) mo and 22 (12.75-42) mo respectively. Of the three illustrative cases, two patients each had ED at presentation and achieved complete remission with platinum based combination chemotherapy. CONCLUSION: LNEPSCC is a rare disease with less than 15 reported cases in world literature. Surgical resection with curative intent is feasible in those with LD while platinum based combination chemoradiation is associated with favorable outcomes in patients with ED. Prognosis of LNEPSCC is better than that of small cell lung cancer in general. PMID:27298771

    Invasive micropapillary carcinoma (IMPC) is an aggressive histologic subtype of adenocarcinoma that has been gaining increased attention over the past twenty years. It is important to recognize IMPC due to its strong association with early lymphovascular invasion (LVI), high risk of lymph node metastasis, perineural invasion and poor prognosis. Controversies regarding IMPC include differentiating from retraction artifact and mimics, clinical significance of proportion of micropapillary component (MC), pathogenesis, biologic nature of the entity and consequently terminology, etc. We herein present a case of rectal IMPC arising from a tubulovillous adenoma. Since HER2 over-expression has been reported in IMPC of the breast and the bladder but never in the colorectum, given the availability of HER2 targeted therapy, HER2 protein expression in our case is examined by immunohistochemical study which shows weak incomplete membrane staining in less than 5% of cells. Literature is reviewed with emphasis on colorectal IMPC as well as aforementioned controversial topics. In summary, more study is needed to resolve the conflicts and build consensus on IMPC.

    BACKGROUND Gastroesophageal cancers, previously considered rare, are rapidly increasing worldwide. We present here a unique case of gastroesophageal carcinoma with metastasis to the rectum. CASE REPORT A 60-year-old female patient presented with constipation, bloating, and weight loss of 4-month duration. She had undergone sleeve gastrectomy 6 years before. Endoscopies performed revealed a friable-looking mucosa in the lower esophagus and a polypoid rectal mass. Histopathological examination from both the esophageal and rectal lesions revealed poorly differentiated adenocarcinoma cells. Immunohistochemistry stain from both specimens was positive for CK7 supporting the gastric site primary with metastasis to the rectum. Further evaluation also revealed metastasis to bone and malignant pleural effusion. Chemotherapy with palliative intent was initiated. CONCLUSIONS Colorectal metastasis is commonly seen from cancers of the breast, stomach, melanoma, kidney, prostate, and ovaries. However, colorectal metastasis from gastroesophageal cancer has never been reported in the medical literature. Diagnosis relies on histopathologic examination and immunohistochemical staining of the tumor. Treatment depends on the tumor stage. Tumors with widespread metastatic disease are candidates for palliative chemotherapy.

    Paraneoplastic syndromes include a variety of disorders that affect the neurologic, endocrine, mucocutaneous, hematologic, and other systems as a result of neoplastic disease. Although their presentations vary, syndromes occur when tumor antigens exhibit cross-reactivity to similar antigens expressed by these systems. The antigens in the nervous system are called "onconeural" antigens. Although many disorders are associated with a comparatively high incidence of paraneoplastic neurologic syndromes, only a few cases have been associated with squamous cell carcinoma (SCC) of the tonsil. We report the case of a 69-year-old man who initially presented with weakness and spastic gait. He was subsequently found to have a characteristic paraneoplastic tractopathy on thoracic magnetic resonance imaging. The subsequent workup and operative intervention identified a T2N0M0 SCC of the tonsil. Following resection, the patient's overall symptoms were significantly alleviated, and his gait improved. A thorough literature search yielded no other report of a tonsillar SCC with associated paraneoplastic thoracic spine tractopathy.

    Purpose Ureteral cancer is a rare entity. Typical symptoms are painless hematuria as well as flank pain. Bone metastasis of ureteral cancer can occur in nearby bone structures, such as the spine, pelvis, and hip bone. Distal bone metastasis, such as that in the calcaneus bone, however, is rare. Case report An 82-year-old woman presented to the orthopedic clinic at the university hospital with a 3-month history of left heel pain. A magnetic resonance imaging (MRI) of her foot demonstrated a calcaneal lytic lesion. A biopsy of the lytic lesion showed urothelial carcinoma with squamous differentiation. A computed tomography (CT) scan of the abdomen and pelvis showed left hydronephrosis and an obstructive mass in the left ureter, at the iliac crossing. The patient received combined therapy that included local radiation, bisphosphonate, and chemotherapy, with complete resolution of her cancer-related symptoms. However, she eventually died from the progressive disease, 20 months after the initial diagnosis. Conclusion This case highlights the rare presentation of ureter cancer with an initial presentation of foot pain, secondary to calcaneal metastasis. Multimodality therapy provides effective palliation of symptoms and improved quality of life. We also reviewed the literature and discuss the clinical benefits of multidisciplinary cancer care in elderly patients. PMID:23610517

    In the United States during the year 2015, approximately 61,560 patients are expected to be diagnosed with kidney cancer and 14,080 to die from the disease. We present the case of a patient with renal cell carcinoma who suffered severe perioperative bleeding and coagulopathy after emergency sternotomy. We also engage in relevant aspects of perioperative anesthesia care including the considerations and management of coagulopathy, liver failure and renal failure in the oncologic patient. The case is a 49-year-old man with vena cava tumor thrombus who underwent radiologic tumor embolization, left radical nephrectomy, and inferior vena cava (IVC) thrombectomy. Postoperatively, he developed sepsis, multiple organ failure, and a pericardial effusion requiring pericardiocentesis. During pericardiocentesis, he suffered an iatrogenic left entricular perforation, requiring an emergency sternotomy and left ventricular repair. Cancer patients are often challenging for surgical and anesthesia teams, emergency care requires an organized and comprehensive approach. The use of recombinant factor VIIa NovoSeven can help in managing severe postoperative bleeding after cardiothoracic surgery in oncologic patients, but further studies should be done to confirm this.

    Schistosomiasis is a parasitic infection that is highly prevalent worldwide, with a variety of species being responsible for causing the disease. In Brazil, however, the only identified species is Schistosoma mansoni. The adult parasites inhabit the blood vessels of the hepatic portal system of the main host. The disease may range from being asymptomatic to provoking liver damage or portal hypertension. Furthermore, ectopic schistosomiasis may develop, and several hypotheses have been raised to explain the occurrence of the disease. This paper describes two cases, one in a 39-year-old woman and the other in a 47-year-old woman. Both had similar symptoms of pain and abdominal distension caused by a large abdominal/pelvic mass. Histopathology of the ovary showed a mucinous cystadenocarcinoma of the intestinal type in the first patient and a papillary serous carcinoma in the second, with both tumors containing viable eggs of Schistosoma mansoni. The neoplasms probably serve as a migratory route for the adult parasites and the embolization of eggs. Nevertheless, there is insufficient evidence to confirm the malignization of a benign lesion due to the presence of Schistosoma mansoni. Few cases have been reported in the international literature on the association between ovarian schistosomiasis and neoplasms. PMID:25587473

    Lichen planus is a benign disorder characterized by an itchy, noninfectious skin rash. Though lichen planus is a common papulosquamous disorder affecting about 1-2% of the population, neoplastic transformation of cutaneous lichen planus lesions occurs very rarely and should be borne in mind while treating nonhealing longstanding lesions of lichen planus. Studies suggest an estimated 0.3-3% risk of malignancy in patients with oral lichen planus, however, cutaneous lichen planus does not carry an increased risk of malignant degeneration. We present a case of a 36-year-old male with a 10-year-long history of hypertrophic lichen planus who presented with a nonhealing ulcer in the left popliteal fossa. The patient underwent wide local excision with superficial skin grafting. Postoperative histopathological examination revealed verrucous squamous cell carcinoma complicating lichen planus. In view of underlying structure involvement, adjuvant radiation therapy was given. This case is being reported to emphasize the infrequent possibility of development of malignancy in cutaneous lichen planus, especially if it presents as a longstanding, nonhealing, itchy lesion with patchy areas of depigmentation in the lower limbs.

    We discuss the histological and immunohistochemical features of 6 cases of urothelial carcinomas of lipid cell variant and 4 cases with shadow cell differentiation, one of which showed additionally sebaceous differentiation, one of which shows additional sebaceous differentiation, from our archive cases from the last 15 years. Conventional urothelial carcinoma (UC) was seen in all lipid cell variant cases, and micropapillary carcinoma was seen in 3. The ratio of the lipid cell component was between 10% and 40% in these 6 cases. Typical histologic features of the lipid cell variant include lipoblast-like cells with a notched nuclear appearance, abundant vacuoles, an eccentric nucleus, and pagetoid spread in some areas. GATA3 and pancytokeratin AE1/AE3 immunohistochemical staining were positive in all cases. Adipophilin was positive in various degrees in 5 of the 6 lipid cell variant cases but was also positive in the case with sebaceous differentiation. α-methylacyl-CoA racemase was positive in the lipid cell areas and negative or focal weakly positive in the conventional UC areas in 4 of the 6 cases. Vimentin, S-100 protein, and PAX8 were negative in the lipid cell component. Follow-up information was available for all cases with follow-up ranging from 6 to 84 months (mean, 34 months). Four patients died of the disease. One pT4 patient who had been followed up for 6 months lives with the disease, whereas another is disease free. In conclusion, the lipid cell variant is a rare UC variant that usually presents at an advanced stage, and tumor cells are histologically similar to lipoblasts, resemble sebaceous differentiation, and show positive immunohistochemical staining with adipophilin.

    INTRODUCTION Metastases to the breast from extra-mammary tumors are uncommon and few sporadic cases are reported in the international literature. An accurate differential diagnosis of secondary cancer is mandatory because both prognosis and treatment differ with respect to primary breast tumors. PRESENTATION OF CASE We present the case of a 70-year-old woman with an isolated metastasis to the breast occuring 9 years after undergoing a nephrectomy for Renal Cell Carcinoma (RCC). Clinical examination revealed a palpable and mobile mass in the right breast with an enlarged ipsilateral axillary lymph node. Mammographic findings showed a dense, well circumscribed solid mass and the breast ultrasonography findings were those of a hypoechoic homogeneous solid nodule with no posterior attenuation but with prominent peripheral vascularity. A tru-cut biopsy was conclusive for a metastatic deposit by RCC. A whole-body CT scan showed no evidence of further recurrences. The patient underwent metastasectomy and exeresis of the papable lymphnode. DISCUSSION In patients with former surgery for RCC, a diagnosis based on a preoperative biopsy allows to indicate the proper surgical treatment: in facts, as compared to primary breast tumors treatment, the rationale to pursue wide surgical margins is pointless in cases of metastases and, similarly, the biopsy of the sentinel lymphnode is void of sense due to the lack of its physiopathological prerequisite. CONCLUSION We suggest to consider a micro-histological biopsy of any new breast lesion appearing in a patient with a history of treatment for RCC. Prompt diagnosis is necessary to choose the right treatment. PMID:24632302

    Adalimumab is an anti-tumor necrosis factor α (TNF-α) agent approved for the treatment of ankylosing spondylitis (AS); psoriatic arthritis; and moderate to severe cases of rheumatoid arthritis (RA), plaque psoriasis, Crohn disease, ulcerative colitis, and polyarticular juvenile idiopathic arthritis. Evidence suggests that anti-TNF-α agents may increase a patient's risk for some types of cancers, including cutaneous squamous cell carcinoma (SCC). Cutaneous nonmelanoma skin cancers (NMSCs) have occurred during treatment with etanercept, infliximab, and adalimumab in the setting of RA and psoriasis, but data related to AS are less clear. We report the case of a 29-year-old woman with AS treated with adalimumab for 2 years who developed invasive SCC of the lower lip. We advocate increased NMSC surveillance in patients undergoing treatment with anti-TNF-α agents.

    We report 2 cases of invasive ductal carcinoma of the breast occurring near a phyllodes tumor. The first case was ofa 58- year-old woman who had a tumor in her right breast and visited our hospital. Following a core needle biopsy (CNB), a malignant phyllodes tumor was diagnosed. We performed a lumpectomy for the phyllodes tumor, with 1.5-cm surgical margins. Pathological diagnosis of the resected specimen confirmed the malignant phyllodes tumor. A ductal carcinoma in situ (DCIS) was also discovered near the phyllodes tumor. The second case was of another 58-year-old woman who had a big tumor in her right breast and visited our hospital. CNB resulted in pathological diagnosis ofa benign phyllodes tumor. The tumor was removed by a lumpectomy with 1.5-cm surgical margins. The pathological diagnosis from the resected specimen was borderline phyllodes tumor with invasive ductal carcinoma in the proximity. In both cases, DCIS could not have been diagnosed preoperatively.

    2013-01-01

    Background The early phase of salivary gland carcinomas with high-grade transformation (HGT) is extremely rare. We reported one case of adenoid cystic carcinoma (AdCC) with early HGT, herein. Case presentation The patient was a 27-year-old Japanese woman who suffered from swelling of the left parotid region. Most of this tumor consisted of typical AdCC histology, whereas the central area of this tumor was composed of solid growth component by atypical cells with clear cytoplasm and marked nuclear atypia. Immunohistochemically, this area was strongly and diffusely positive for epithelial membrane antigen, p53, p16, Her-2, cyclin A and cyclin B1. The Ki-67 labeling index of this area was high, entirely different from that of AdCC area. Conclusion Overall, this area was an early phase of AdCC-HGT. This case is the second case of early AdCC-HGT. We discuss the development of salivary gland carcinoma with HGT.

    Brachyury is a transcription factor of the T-box family typically expressed in notochord and chordoma. Some studies report brachyury as highly specific for chordoma, whereas others have concluded that brachyury is expressed in many types of common carcinomas by reverse transcription polymerase chain reaction and immunohistochemistry and could be involved in the epithelial-mesenchymal transition and metastatic process. In this study, we immunohistochemically evaluated 5229 different tumors for nuclear brachyury expression using a new rabbit monoclonal antibody and automated immunostaining (Leica Bond Max). Only nuclear labeling was scored, and antibody dilution of 1:2000 was used. In normal tissues, only rare cells in seminiferous tubules were labeled; all other organs were negative. All chordomas (75/76), except a sarcomatous one, were positive, whereas chondrosarcomas were negative. Among epithelial tumors, positivity was often detected in embryonal carcinoma (74%) and seminoma (45%). Pulmonary small cell carcinoma was often positive (41%), whereas pulmonary and pancreatic adenocarcinomas only rarely showed nuclear brachyury positivity (3% to 4%). Common carcinomas such as ductal carcinomas of the breast or adenocarcinomas of the prostate only exceptionally showed nuclear positivity (<1%). No colorectal, hepatocellular, renal cell, squamous cell, thyroid or urothelial carcinoma, or mesothelioma showed nuclear brachyury positivity. Among mesenchymal and neuroectodermal tumors, only isolated cases of melanoma, malignant peripheral nerve sheath tumor, rhabdomyosarcoma, synovial sarcoma, and follicular lymphoma showed nuclear expression. However, as shown previously with lung carcinoma, experiments with lower antibody dilutions (1:200 to 1:500) showed weak cytoplasmic and nuclear labeling in breast cancers. In addition to chordoma, we show here for the first time that nuclear brachyury expression is prevalent in embryonal carcinoma, seminoma, and small cell carcinoma

    Metastatic tumors involving salivary glands arising from the non-head and neck area are very rare. Renal cell carcinoma (RCC) is known for its high propensity for metastasis to unusual localizations. RCC metastasis to the maxillofacial area is an uncommon event (16%), but metastasis to salivary glands is extremely rare. We report a series of 9 such cases retrieved from two institutions. The group included 6 females and 3 males. The age at diagnosis ranged from 60 to 97 years (mean 72.6 years). The tumors involved the parotid gland in 7 cases, and the submandibular and small salivary gland of the oral cavity in 1 case each. The size of tumors ranged from 0.4 to 5 cm. Total parotidectomy with selective neck dissection was performed in 4 cases, while superficial parotidectomy was performed in 1 case and simple resection in 3 cases. Histologically, all the tumors were clear cell renal cell carcinomas, and therefore the differential diagnosis mainly included clear cell variants of salivary gland carcinomas. The parotid gland was the initial manifestation of renal malignancy in 4 of the cases, while in the remaining 5 cases a history of RCC had been known. The salivary gland involvement developed from 11 months to 13 years after the time of diagnosis of the primary tumor. In 2 cases it was the first site of dissemination. Pathologists need to maintain a high index of suspicion for the possibility of metastasis when confronted with oncocytic or clear cell neoplasms developing in salivary glands. RCC, although rare, should be included in this differential diagnosis.

    Parathyroid carcinoma is a rare clinical entity accounting for only 4 per cent of all cases of parathyroid neoplasia. Nonfunctioning parathyroid carcinoma is even rarer. Previously, virtually all patients with these lesions were treated for a nonspecific neck mass. However, in the present case, a preoperative diagnosis of nonfunctioning parathyroid carcinoma was made based on the technetium pertechnetate/thallium 201 subtraction scan. The authors report on the 14th case of nonfunctioning parathyroid carcinoma, a review of the literature, and guidelines for the preoperative and operative evaluation of neck masses suspected to be parathyroid carcinoma.22 references.

    Background Dermatomyositis (DM) is an autoimmune disease characterized by cutaneous Gottron papules, heliotrope rash, and proximal myopathy. It may also present as a paraneoplastic syndrome that can complicate a variety of different cancers, such as lung, cervical, and breast cancer. However, the association with hepatocellular carcinoma (HCC) is extremely rare. Moreover, to our knowledge, there are no previous reports of colonic perforation following steroid pulse treatment for a DM patient. Case Summary A 61-year-old male complained of a skin rash that began in his neck and spread to his face and abdomen. On physical examination, the patient was also found to have symmetrical proximal muscle weakness, abdominal pain, heliotrope rash in the periorbital skin, and poikiloderma on his face and abdomen. Serum level of muscle enzymes was remarkably increased. Muscle examination revealed symmetrical proximal weakness. The diagnosis of DM was made, and steroid treatment was started for symptomatic relief. A search for causative malignancy revealed HCC. Despite steroid therapy for DM, his symptoms did not improve. Additionally, C-reactive protein elevation was seen along with severe abdominal pain on day 14 of admission. Shortly after this, the patient died of septic shock due to suppurative peritonitis after perforation of the ascending colon. Conclusion Here, we present a rare case of DM caused by non-hepatitis-associated advanced HCC with colonic perforation. The cause of colonic perforation is still unclear. This case demonstrates the need to carefully monitor abdominal pain in DM patients as symptoms can be masked by steroid therapy. PMID:27790119

    The diagnosis of Cushing's syndrome (CS) may sometimes be cumbersome. In particular, in ACTH-dependent CS it may be difficult to distinguish between the presence of an ACTH-secreting pituitary adenoma and ectopic ACTH and/or CRH secretion. In such instances, the etiology of CS may remain unknown despite extensive diagnostic workout, and the best therapeutic option for each patient has to be determined. We report here the case of a 54-yr-old man affected by ACTH-dependent CS in association with a left adrenal adenoma and medullary thyroid carcinoma (MTC). He presented with clinical features and laboratory indexes of hypercortisolism associated with elevated levels of calcitonin. Ectopic CS due to MTC was reported previously. In our case hypercortisolism persisted after surgical treatment of MTC. Thorough diagnostic assessment was performed, in order to define the aetiology of CS. He was subjected to basal and dynamic hormonal evaluation, including bilateral inferior petrosal sinus sampling. Extensive imaging evaluation was also performed. Overall, the laboratory data together with the results of radiological procedures suggested that CS might be due to inappropriate CRH secretion. However, the source of CRH secretion in this patient remained unknown. It was then decided to remove the left adenomatous adrenal gland. Cortisol level fell and has remained within the normal range nine months after surgery. This case well depicts the complexity of the diagnostic workout, which is needed sometimes to correctly diagnose and treat CS, and suggests that monolateral adrenalectomy may represent, at least temporarily, a reasonable therapeutic option in occult ACTH-dependent hypercortisolism.

    Primary peritoneal carcinoma (PPC) is a type of rare malignant epithelial tumor. Metastasis from PPC to breast has been rarely reported. PPC originates de novo from the peritoneal tissues rather than invasion or metastasis from adjacent or remote organs. PPCs have been implicated in many cases of carcinomas of unknown primary origin. It is similar to ovarian cancer (OvCa), because it shares the same common embryonic origin, the coelomic epithelium (mesodermal origin). The mechanism of oncogenesis remains elusive. In this article, we report a rare case of PPC in a patient 10 years after total abdominal hysterectomy and bilateral salpingooophorectomy for uterine leiomyoma, which was widely spread in the abdomen and metastasized to the colon, liver and distant organs including breast. The treatment is similar to that of primary ovarian cancer. We also reviewed the primary peritoneal cancer metastatic to breast and discuss the possible mechanisms and biology of primary peritoneal cancer, using experimental and animal model. PMID:27807506

    Introduction Verrucous carcinoma of the external genitalia and perianal region is a rare variant of well-differentiated squamous cell carcinoma. It has been reported to have limited metastatic potential. Case presentation We report the case of a 54 year-old Moroccan man who presented with locally advanced giant condyloma acuminatum (Buschke–Löwenstein tumor) after prolonged intervals of neglect (approximately 10 years). The disease covered his suprapubic, external genitalia and perianal region. It was locally aggressive with extensive tissue destruction. After a biopsy of the lesion, the diagnosis of verrucous carcinoma was confirmed. He initially received chemoradiotherapy, followed by extensive local excision, but he developed septic shock and died a few days later. Conclusions The purpose of this case report is to present a case of verrucous carcinoma arising in an extensive giant condyloma acuminatum (Buschke–Löwenstein tumor) and discuss the literature on its diagnosis and management.

    Clear cell papillary renal cell carcinoma (CCPRCC) was recently included in the International Society of Urological Pathology Vancouver Classification of Renal Neoplasia as a subtype of RCC that is morphologically, immunohistochemically, and genetically distinct from both clear cell renal cell carcinoma (CCRCC) and papillary renal cell carcinoma. In our clinical practice we have observed tumors with overlapping histologic features of CCPRCC and CCRCC; therefore, our aim was to describe the morphologic, immunohistochemical, and clinical characteristics of these tumors. We examined a large series of consecutive nephrectomies diagnosed as CCRCC and found 37 tumors with morphologic overlap between CCRCC and CCPRCC, identifying 2 patterns. Pattern 1 tumors (N=19) had areas diagnosable as CCRCC admixed with foci having a prominent linear arrangement of nuclei away from the basement membrane imparting a resemblance to CCPRCC; however, other morphologic features commonly seen in CCPRCC (such as branching acini and cystic spaces with papillary tufts) were not typical and, when present, were focal or poorly developed. Pattern 2 (N=18) tumors had 2 discrete areas, one area with an appearance strongly resembling CCPRCC and the other with higher grade nuclei and features diagnosable as CCRCC, sometimes including rhabdoid differentiation, sarcomatoid differentiation, necrosis, and high-stage disease. Four (21%) of the pattern 1 tumors had grade 3 nuclei in the CCRCC-like areas, and 4 were high stage (pT3a). Of the 16 immunostained pattern 1 tumors, all expressed cytokeratin 7 (CK7) at least focally in the CCPRCC-like areas, strongly and diffusely in 9 (56%) cases; 12 (75%) showed negative to focal and/or weak CK7 expression in the CCRCC-like areas. CD10, α-methylacyl-CoA-racemase, high-molecular-weight cytokeratin, and carbonic anhydrase IX (CA IX) had no significant differential expression between these foci. No cup-like staining pattern was seen with CA IX. Two (11%) patients

    This report describe the case of a patient presenting with pulmonary metastases from a penile cancer, where the presence of the human papillomavirus (HPV) type 16 DNA both in the primary tumor and in the distant metastases confirmed the spreading of the disease, ruling out a possible primary lung squamous cell carcinoma. Indeed, according to the findings, the HPV genotyping test might help in the identification of metastatic disease from anogenital malignancies or other HPV-related cancers.

    We present here two cases of papillary thyroid carcinoma (PTC) in patients affected by Lynch syndrome (LS). The first case is a 47-year-old woman with typical hereditary non-polyposis colorectal cancer (HNPCC) syndrome, reported with endometrial and ovarian carcinoma at age 43, and colon cancer at age 45. The patient underwent total thyroidectomy and central node dissection in 2007, at 47years old, with a histological diagnosis of PTC (T1aN1a). Molecular genetics showed a germ-line mutation of the MLH1 gene, 1858 G>T(E620X), with substitution of glycine with a stop codon at position 620. This mutation has pathogenetic significance and was considered responsible for the various tumours of the HNPCC spectrum. In particular, in the same kindred, spanning 5 generations, there were 5 members with colorectal cancer, 4 with endometrial cancer, 3 with gastric and 2 with breast cancer. The second case is a 34-year-old man with typical HNPCC syndrome with colonic resection for colon cancer at age 21. The patient underwent total thyroidectomy with central and lateral node dissection in 2010, at age 34, with a histological diagnosis of PTC with nodal metastases (pT4N1b). Molecular genetic analysis showed a germ-line mutation of the MSH2 gene (thymine insertion at position 907). This mutation had pathogenetic significance and was considered responsible for HNPCC development. Two similar cases have been reported: a 39-year-old woman, and a 44-year-old woman, affected by HNPCC syndrome, with anaplastic thyroid carcinoma and undifferentiated thyroid carcinoma, respectively. We reviewed the Lynch syndrome literature on the history, genetics and expanding tumour spectrum of this condition.

    Pancreatic metastases represent 2% of pancreatic tumors. The neoplasms most frequently metastasizing to the pancreas are breast, lung, melanoma and kidney tumors. We present the cases of two patients with pancreatic metastases from renal carcinoma diagnosed 4 and 8 years after the diagnosis and surgical treatment of the primary renal tumor. In both patients, endoscopic ultrasound was useful in the detection and characterization of these pancreatic lesions and allowed fine-needle aspiration for cytological study to be performed.

    Primary cutaneous apocrine gland carcinoma, which is a type of sweat gland carcinoma, is an extremely rare type of cancer. Clinical courses of this type of cancer usually progress slowly but can, occasionally, be associated with rapid progression. This case report describes a 53-year-old Korean man with primary cutaneous apocrine gland carcinoma that arose from an apocrine gland in the areola tissue. The patient visited our hospital because of a large, painful chest wall mass beneath the right nipple. The mass had been present for more than eight years but had grown rapidly over the past few months. The patient was initially diagnosed with a benign cystic mass, and we performed a wide excision with a clear margin and without lymph node dissection. The mass was a well-encapsulated cystic lesion that contained old blood material, and there was no invasion into the surrounding tissue. The final pathology showed that the mass was a primary cutaneous apocrine gland carcinoma that arose from the areola apocrine sweat gland, not from the breast parenchymal tissue. Herein, we report an extremely rare chest wall mass unfamiliar to thoracic surgeons.

    Introduction Tumor rupture and pulmonary metastasis in patients with hepatocellular carcinoma are both associated with poor prognosis and treatment strategies are controversial. Case presentation Here we report a 50-year-old man with survival of over 90 months after undergoing an extended right lobectomy for a ruptured hepatocellular carcinoma and then repeated resections for pulmonary metastasis during the followup period. Conclusion This case report shows that surgical resection can be an effective treatment for patients with both ruptured hepatocellular carcinoma and pulmonary recurrences. PMID:18588711

    Hyalinizing clear cell carcinoma (HCCC), so-called clear cell carcinoma, not otherwise specified (CCC (NOS)), of the salivary glands is a rare and low-grade malignant tumor. We report a case of HCCC so-called CCC (NOS) (referred to as HCCC) of the minor salivary gland of the buccal mucosa. A 52-year-old woman had presented with a gradually growing and indolent mass in the right buccal mucosa for about two years. The first biopsy histopathologically suggested the possibility of malignancy derived from the minor salivary glands. A month later, she visited our hospital. The tumor measured approximately 1.5 cm in diameter and was elastic hard, smooth, and well movable. Image examinations demonstrated internal homogeneity of the lesion, which had a smooth margin, in the right buccal mucosa. Complete tumor resection followed by covering with a polyglycolic acid sheet and fibrin glue spray was performed without surgical flap reconstruction. Histopathological findings revealed proliferating tumor cells with clear cytoplasm surrounded by hyalinizing stroma in the submucosal minor salivary glands. Immunohistochemical stains revealed these tumor cells to be positive for epithelial cell markers but negative for myoepithelial ones. These findings confirmed the diagnosis of HCCC. Good wound healing and no evidence of local recurrence and metastasis have been shown since surgery. PMID:26600962

    Gallbladder carcinoma (GBC) is a rare and highly aggressive disease. The diagnosis of this cancer is difficult due to its occult onset. Hence, GBC is often detected late and at an advanced stage. Although physicians and researchers are continually working to improve the treatment for advanced-stage disease, GBC is usually associated with short survival times. The present study describes a case of GBC that was first diagnosed with accompanying cholecystolithiasis at the time of cholecystectomy. Cancer relapse occurred 1.5 years after the cholecystectomy. Multidisciplinary collaboration was involved in the decision-making process for the treatment of this aggressive recurrence, and the survival time was successfully extended to 26 months. Importantly, high-grade intraepithelial neoplasia and positive margins had previously been detected post-cholecystectomy at a different institution, but were ignored. Relapse may have been preventable had the cancer been diagnosed when it was initially observed. Taken together, these findings suggest that multidisciplinary collaboration should be considered for the management of advanced GBC, whereby patients will benefit from improved survival times. Furthermore, it is recommended that samples obtained from patients undergoing cholecystectomy should more carefully analyzed for evidence of cancerous or precancerous tissues. PMID:27698845

    Pancreatic panniculitis is a rare type of disorder associated with pancreatic diseases. We describe here a case of 54-year-old man who was admitted to the Department of Dermatology with the diagnosis of erythema nodosum. The patient presented with a 9-month history of painful erythematous nodules on the extremities, joint pain and swelling, and weight loss. A highly elevated level of pancreatic lipase was found on the laboratory examinations. The biopsy specimens from the skin lesions showed subcutaneous fat necrosis. Abdominal computed tomography (CT) revealed a large mass with central necrosis in the body and tail of the pancreas. Distal pancreatectomy, splenectomy and partial transverse colectomy were successfully performed on day 17 of the hospitalization. The histopathologic findings supported the diagnosis of acinar cell carcinoma of the pancreas (ACCP). Postoperatively, the level of serum lipase returned to normal, and the skin lesions and joint manifestations gradually regressed. However, the swelling did not significantly resolve in the left knee. In view of the non-specific clinical presentation of this disease, clinicians should be alert and have a high index of suspicion for pancreatic panniculitis.

    Abstract Background: Adrenocortical carcinoma (ACC) may rarely be a component of inherited cancer syndromes such as Li-Fraumeni syndrome and Beckwith-Wiedemann syndrome. ACC caused by a BRCA2 mutation has never been reported. Methods: Nucleotide sequencing of BRCA2 in lymphocyte and tumoral DNA of a 50-year-old male who presented with an androgen-secreting ACC and a strong family history of breast, ovarian, and pancreatic cancers. Results: A germline BRCA2 2 bp heterozygous deletion at nucleotide 8765 (8765delAG) leading to a frameshift mutation (p.Glu2846GlyfsX23) was detected. Only the BRCA2 deleted allele was retained in the ACC tumoral DNA compared with the control DNA supporting a loss of heterozygosity in the tumor. Conclusion: This is the first reported case of a patient with ACC associated with a BRCA2 germline mutation. Loss of heterozygosity in ACC DNA suggests a causal link with the BRCA2 8765delAG mutation. PMID:27603373

    We present the first case (male, 35 years old) of a mammary analogue secretory carcinoma occurring in a submandibular gland and document findings on fine needle aspiration cytology. On histology, the tumor displayed characteristic features: circumscribed nodules composed of bland, pink to light red neoplastic cells with low proliferative/mitotic activity arranged in tubular, vaguely cribriform, and microcystic structures containing Periodic acid Schiff-positive, diastase-resistant secretory material. Immunohistochemistry showed strong and diffuse positivity for cytokeratin 7, S100 protein, and vimentin, as well as moderate to strong immunoreactivity for c-kit in the majority of tumor cells. A rearrangement of the ETV6 gene on fluorescence in situ hybridization was documented. The patient underwent an ipsilateral selective (levels I-IV) neck dissection which showed metastasis in 3 out of 36 lymph nodes (levels 1-3). Adjuvant radiotherapy was administered. No local recurrence or metastatic disease has been detected during a follow up period of 28 months.

    Published reports on salvage treatment for trachea reconstruction after total thyroidectomy or partial tracheotomy are available, some of them using structures of the trachea itself, auricular cartilage, a musculocutaneous flap, or other methods. In our report, we emphasize the importance of a search for a new material and approach for sparing surgery. The purpose of this article is to describe a case of a successful sparing surgery in a patient with advanced thyroid papillary carcinoma invading the trachea. After total thyroidectomy in 2012, partial resection of the trachea was performed in 2014. The lesion defect was 5.5 × 2.3 cm in size, located between 4 (2nd–6th) tracheal cartilaginous rings and involving about a semicircumference. It was reconstructed with the aid of the knitted TiNi-based mesh endograft, which has been prefabricated in the sternocleidomastoid muscle and further covered with the skin draped over the wound. The tracheostoma was fully closed 6 weeks after the surgery. There were neither side effects nor complications. This kind of tracheal surgery for extensive lesions demonstrates good functional and cosmetic outcomes. PMID:27990114

    Oral candidiasis is a significant problem in immune-compromised patients. The most common forms of mucosal candidiasis are oropharyngeal, oesophageal and vaginal, and more than 90% of HIV positive persons will manifest at least one episode of oropharyngeal candidiasis. Local and systemic factors such as uninterrupted daily use of a prosthesis by patients, smoking habit, as well as high glucose intake may contribute to the development of the lesion. The aim of this article is to report an uncommon case of oral candidiasis presenting an aggressive clinical behaviour in a 64-year-old male patient, with a significant smoking habit and a medical history of non-controlled diabetes. The lesion affected the hard and soft palate of the right side, revealing erythematous and ulcerated areas, elevated borders and central portions resembling necrosis, mimicking the clinical features of oral squamous cell carcinoma. However, the correct diagnosis of oral candidiasis was obtained after histopathological and cytological examinations and the patient was easily treated with traditional antifungal drugs and correction of his glucose levels.

    Bilateral renal cell carcinomas (RCCs) pose a challenge for clinical treatment and management. Most bilateral RCCs are sporadic, and do not show a hereditary pattern indicative of VHL syndrome or other inherited cancers. The origin and evolution of these sporadic bilateral RCCs remains elusive. We obtained normal and tumor samples from two male patients suffering from early stage synchronous bilateral clear cell RCC (ccRCC), and analyzed genomic DNA using whole exome sequencing and bisulfite pyrosequencing. We detected distinct 3p loss of heterozygosity (LOH) in both tumors in each patient. Two tumors within the same patient harbored distinct driver mutations and different CpG hypermethylation sites in the VHL promoter. Moreover, tumors exhibit independent evolutionary trajectories. Therefore, distinct 3p LOH, combined with contingent driver gene mutations and independent VHL hypermethylation, led to independent tumor origin and parallel evolution of bilateral ccRCC in these two patients. Our results indicate that tumors in these two cases were not due to common germline oncogenic mutations. They were results of multiple de novo mutations in each kidney, rather than primary ccRCC with contralateral renal metastasis. Therefore, histopathologic and genetic profiling from single tumor specimen may underestimate the mutational burden and somatic heterogeneity of bilateral ccRCCs. PMID:27383411

    The present report aimed to study genetic alterations underlying extraovarian peritoneal serous papillary carcinoma (EPSPC), which have not previously been systematically investigated. A case of EPSPC was identified, and its genetic alterations were assessed by combining comparative genomic hybridization and whole-exome sequencing technologies to investigate the genomic landscape, including copy number variations and mutations in EPSPC. It was found that a large number of germline mutations were present, which may have predisposed the patient to the occurrence of this disease. Copy number gains were found in a range of chromosomes, including 4q, 5q, 8q, 10q, 15q, 16p, 18q, 20p, 20q and Xq. Large-scale copy number loss occurred in chromosomes 2p, 13q, 16q, 17p and 17q. Through use of whole-exome sequencing, germline mutations were widely found that were associated with cancer development, including mutations in the BRCA1, DNA repair associated (BRCA1), BRCA2, tumor protein 53, erb-b2 receptor tyrosine kinase 2, matrix metalloproteinases and ADAM metallopeptidase domain-containing genes. In addition, 165 somatic mutations, including 52 missense mutations and 7 short insertions or deletions, were also identified. In summary, the EPSPC was undergoing profound genomic rearrangement and somatic mutation, which may have led to its initiation and development, and the present study discussed the genetic basis of this highly malignant cancer.

    We report 2 cases of primary thymic adenocarcinoma with enteric differentiation. One carcinoma occurred in a 41-year-old man as a 7-cm-diameter cystic tumor and the other one in a 39-year-old woman as a 6-cm-diameter solid mass. Both tumors were located in the anterior mediastinum. Clinical staging did not reveal any extrathymic tumor. Histologically, the tumors were classified as adenocarcinoma, not otherwise specified, and a mucinous (colloid) carcinoma, respectively. Immunohistochemically, both tumors were positive for cytokeratin 20 (CK20), CDX2, and carcinoembryonic antigen, reflecting enteric differentiation. A review of the literature on 43 other cases of primary thymic adenocarcinomas suggested 11 further cases with enteric differentiation, as assessed by CK20 and/or CDX2 expression. We propose that thymic adenocarcinoma with enteric differentiation represents a novel subtype of thymic carcinoma. It is mostly of mucinous morphology and frequently associated with thymic cysts. The clinical outcome is variable. Recognition of primary thymic adenocarcinoma with enteric differentiation is helpful for the differentiation from metastatic disease, mainly from the gastrointestinal tract.

    Background Accurate assessment of the depth of tumor invasion (DI) in microinvasive squamous cell carcinoma (MISCC) of the tongue is critical to prognosis. An arithmetic model is generated to determine a reliable method of measurement of DI and correlate this with the local recurrence. Material and Methods Tumor thickness (TT) and DI were measured in tissue sections of 14 cases of MISCC of the tongue, by manual ocular micrometer and digital image analysis at four reference points (A, B, C, and D). The comparison of TT and DI with relevant clinicopathologic parameters was assessed using Mann Whitney U test. Reliability of these methods and the values obtained were compared and correlated with the recurrence of tumors by Wilcoxon Signed Ranks Test. 3D reconstruction of the lesion was done on a Cartesian coordinate system. X face was on the YZ plane and Z face was on the XY plane of the coordinate system. Results Computer generated 3D model of oral mucosa in four cases that recurred showed increased DI in the Z coordinate compared to the XY coordinate. The median DI measurements between XY and Z coordinates in these cases showed no significant difference (Wilcoxon Signed Ranks Test, p = 0.068). Conclusions The assessment of DI in 3 dimensions is critical for accurate assessment of MISCC and precise DI allows complete removal of tumor. Key words:Depth of invasion, tumor thickness, microinvasive squamous cell carcinoma, tongue squamous cell carcinoma. PMID:26449426

    Collecting duct carcinoma (CDC) is a rare and aggressive form of renal cell carcinoma (RCC) arising from the principal cells of the collecting duct. One third of cases present with metastatic disease, but many present in a manner similar to conventional RCC or urothelial carcinoma (UC). We discuss a case of CDC which presented as a small mass at the cortico-medullary junction, and was discovered at robotic partial nephrectomy (RPN) to be grossly involving the collecting system. A 62-year-old man presented with a small renal mass suspicious for RCC, which was found on computed tomography (CT) after an episode of gross hematuria. After thorough workup, RPN was attempted; however, intraoperatively the mass was found to be involving the collecting system. Radical nephroureterectomy was performed, and the pathology report revealed CDC. CDC is a rare and aggressive form of RCC. While many cases are metastatic at diagnosis, most patients present with the incidental finding of a small renal mass. There are no reports of a CDC involving the collecting system at RPN after negative ureteroscopy preoperatively. The adjuvant therapeutic options for CDC are limited, and long term survival is poor.

    Neuroendocrine Carcinoma of the Prostate (NECP) is rare and only few cases have been reported, constituting less than 0.5% of prostatic malignancies. We report a rare case of large bowel obstruction from NECP posing a further challenge in management due to resistant hypokalaemia. A 70-year-old man presented with clinical signs of large bowel obstruction who was known to have prostatic carcinoma three years ago, treated initially with hormone therapy then chemoradiation. The blood profile showed a severe hypokalaemia and CT scan revealed liver and lung metastases apart from confirming large bowel obstruction from local invasion of NECP. Severe hypokalaemia was believed to be caused by paraneoplastic syndrome from tumor burden or by recent administration of Etoposide. Intensive potassium correction through a central venous access in maximal doses of 150 mmol/24 hours under cardiac monitoring finally raised serum potassium to 3.8 mmol/L. This safe period allowed us to perform a trephine colostomy at the left iliac fossa. The postoperative period was relatively uneventful. This first case report is presenting a rare cause of large bowel obstruction from a neuroendocrine carcinoma of prostate and highlights the importance of an early, intensive correction of electrolytes in patients with large tumor burden from NECP.

    A 33-year-old Chinese woman was admitted to our hospital because of an elevated serum alpha-fetoprotein (AFP) level (300 ng/mL) found in a regular medical checkup. Computed tomography imaging of the abdomen revealed a 1.6 × 2.2 cm low-attenuation mass in the head of the pancreas, with no enlarged lymph nodes and no metastatic liver nodules, and a pancreaticoduodenectomy was performed and the tumor was completely removed. The tumor was solid, unencapsulated and poorly demarcated, measuring 2 × 1.4 × 1.8 cm, and the cut surface was grey-yellowish. Histologically, most of the areas of the tumor were composed of small monotonous and round shaped neuroendocrine cells, and approximately 20% of the areas were cells with indistinct cytoplasmic borders, large oval nuclei, prominent nucleoli and abundant eosinophilic cytoplasm, resembling the appearance of HCC. Immunohistochemical stains revealed that the neuroendocrine areas were diffusely positive for chromogranin, and the hepatoid areas showed diffuse and strong positive reaction to AFP. After surgery the AFP level reduced to normal. She received six cycles of postoperative chemotherapy and three years after the surgery was found to have an elevated serum AFP level again which gave rise to the suspicion of tumor recurrence, and a positron emission tomography-computed tomography confirmed the speculation by showing a hypermetabolic lymph node behind the body of the pancreas. She then underwent radiotherapy and the AFP level reduced to normal. Up till now she has survived 46 months since the initial diagnosis. This case and previous cases suggest that the serum AFP could be a useful marker for early detection of the disease, but careful differential diagnosis should be performed, and AFP could also be a marker for evaluation of therapeutic response and recurrence of the AFP-producing hepatoid carcinomas of pancreas.

    This paper deals with a special type of mammary carcinoma, generally of high-grade malignancy, which carries a remarkably good prognosis—the so-called “medullary carcinoma of the breast with lymphoid infiltrate.” Probably the increased lymphoid tissue seen in these tumours is concerned with cell-mediated and humoral immunological reactions and reflects a strong host-defence mechanism which is responsible for the remarkably high survival rates following radical treatment. Since the evidence for host resistance to malignant disease is based largely on animal data, the opportunity to study a group of patients followed for 20 years, in whom this type of defence reaction appears to exist, is of considerable clinical interest. Among 1,411 cases of breast cancer there were 104 with medullary carcinoma (7·4%), for which the corrected 5- to 20-year survival rates have been calculated. After 20 years 74% of cases with operable medullary tumours were alive, compared with 14% of cases with similar stage non-medullary cancer. In the presence of histologically proved axillary metastases the 20-year survival rate was 61% for medullary cases, compared with only 13% for other types of breast cancer. In 30 cases of medullary cancer in which the axilla was free, the corrected 20-year survival rate was 95% following a combination of radical operation and radiotherapy. No evidence could be found that axillary dissection or postoperative irradiation is harmful to women with operable highly malignant breast cancer in whom a well-marked host resistance is thought to be present. A combination of radical mastectomy and postoperative irradiation appears to be the most effective treatment for such cases. The present grounds for rejecting a radical approach to treatment of breast cancer, based on current immunological considerations, are regarded as being quite inadequate. PMID:5448777

    SUMMARY Objective: Non-small cell lung carcinoma is an aggressive phenomenon and the epigenetical alterations of some tumor supressor genes have been reported for the different tumor types. Case Presentation: It is presented a case report concerning a 43 years old male with NSCLC on the lower segment of the right lung. The patient underwent a diag-nostic excisional thin-needle biopsy and after the histological confirmation. We examined the promoter methylation status of some distinct tumor supressor genes in tumoral and blood tissues of the case after sodium bisulfite conversion and DNA amplification with methylation specific multiplex PCR technique. Both tissues were also searched for G to A transitions in codons 12 and 13 of the K-ras proto-oncogene. Results: Tumor specimen showed fully methyl pattern profiles for the SFRP2, p16, DAPK1 and partially hyper-methylated profile for the p53 and MGMT genes in this case with non-small lung carci-noma. Blood speicemen showed normal hypomethylated profiles for all studied TS genes. The K-ras proto-oncogene was in normal structure both in blood and tumoral spiecemens that examined. Conclusion: Results indicate that genes exhibit tumor suppressor activi-ties in blood, but exhibit epigenetic inactivation in carcinoma cell. These findings strongly support the hypothesis that epigenetic mechanisms may play an important role in the non-small cell lung carcinogenesis in human. PMID:21264081

    Sex steroids influence the development and course of human genital carcinomas including breast, testis, prostata, and ovarian cancers. (1) Other carcinomas such as hepatoma, cholangioma, and pancreatic cancer have also been reported to be related to sex hormones. (2-4) The existence of sex hormone receptors has been demonstrated immunohistochemically in specimens of these diseases. We recently encountered a patient in whom an ampullary carcinoma developed 39 months after the start of androgenic steroid therapy for aplastic anemia. Immunohistochemic analysis of resected tumor specimens of the patient suggested a possible hormonal effect on the tumor oncology.

    Abstract Background: Primary salivary gland–type tumors of lung are rare. Epithelial–myoepithelial carcinoma (EMC) of the lung is a minor salivary gland–type tumor subtype. Methods: We report a very rare case of EMC located in the peripheral left lower lobe that was diagnosed in a 58-year-old man and this is the first study in which we summarize all the patients with primary peripheral lung EMC concerned with the clinical features. Informed consent was obtained from the patient. Results: Chest computed tomography displayed an anomalous soft tissue mass with slightly lobular borders in the peripheral segment of the left lower lobe and closed to the visceral pleura. The surgery was performed by using video-assisted thoracic surgery. Grossly, the tumor was solitary, well-circumscribed, and unencapsulated endobronchial lesion. A microscopic examination revealed that it was circumscribed, although the tumor borders may show single cells or clusters of cells proliferating away from the main tumor mass. The inner tubular layer showed epithelial cell characteristics, whereas the outer layer exhibited myoepithelial cell characteristics. Immunostaining for P40, P63, and cytokeratin 5/6 was positive. However, the anaplastic lymphoma kinase-V, thyroid transcription factor-1, synaptophysin, chromogranin A and napsin A were negative. Conclusions: Literature review showed that most of patients with peripheral EMC were asymptomatic. Computed tomography and magnetic resonance imaging scans are able to indicate the presence of peripheral EMC. Pathological analysis is an effective method to clarify the diagnosis. Surgery is a regular treatment method. To facilitate the preoperative diagnosis and avoid the misdiagnosis of such a rare disease, more cases will need to be reported. PMID:27583848

    The fan beam thickness (FBT) in helical tomotherapy is defined by a pair of collimators parallel to the rotational orbit of the radiation beam and is fixed for a specific patient treatment. The aim of this case study is to evaluate the dosimetric influence of changing the FBT in the treatment of a nasopharyngeal carcinoma (NPC) patient. The subject was a T2N1M0 stage NPC patient. The planning target volumes (PTVs) of the primary nasopharyngeal tumor and the left and right cervical lymphatics were delineated along with the organs at risk (OARs) in the corresponding computed tomography slices. Three treatment plans with FBT of 1.0 cm, 2.5 cm, and 5.0 cm (FBT-10, FBT-25, and FBT-50) were generated separately based on similar dose constraints and planning parameters. The dosimetric results of the PTV and OARs were collected and compared among the 3 treatment plans. The differences in the dose parameters of the PTVs were small among the 3 plans. The FBT-10 plan demonstrated the most homogeneous PTV doses with the smallest homogeneity indices (HIs). The FBT-50 plan delivered the highest dose to the OARs and the FBT-10 plan delivered the lowest. The differences between the 2 plans were more significant in the spinal cord, optic chiasm, optic nerves, and lens. This case study demonstrated that the variation of FBT in tomotherapy affected the quality of the treatment plan mainly in the OAR doses, but not so much in the PTV. Increasing the FBT reduced the effectiveness in the sparing of OARs.

    Solitary extramedullary plasmacitomas (SEMP) of the liver are very rare. We report the case of an elderly woman with a huge symptomatic SEMP of the liver mimicking hepatocellular carcinoma (HCC). The patient was a 89-year-old woman who presented with severe abdominal pain and a huge solid mass in the right hypochondrium. The laboratory data on admission revealed normal liver function tests. A multiphasic computed tomography (CT) showed a huge solid mass of the left hemiliver, hypoattenuating on noncontrast images, dishomogeneously hyperenhancing in the late arterial phase, with washout in the portal venous and equilibrium phases. A 18F-FDG positron emission tomography (18F-FDG PET)-CT scan documented a marked FDG uptake within the lesion, without evidence of extrahepatic metastases. We considered the clinical and radiologic findings consistent with the diagnosis of high-grade HCC with areas of intratumoral necrosis preluding to possible tumour rupture. Surgical resection was ultimately considered feasible with a reasonable risk and the patient underwent left hepatectomy with diaphragmatic resection. Pathological examination exhibited an extramedullary plasmacytoma. At immunohistochemical analysis neoplastic cells were positive for CD45, CD38, IRF4, HTPD52, kappa-chain, but negative for lambda- chain; Mib-1 proliferation index was 50%. Subsequent clinical evaluation excluded any sign of multiple myeloma, so that a diagnosis of truly localized SEMP of the liver was finally established. To our knowledge, this is the first case of a solitary extramedullary plasmacitoma of the liver undergoing successful radical liver resection. The patient is alive and well 5 years after surgery without evidence of local recurrence and of systemic disease.

    Purpose Invasive ductal carcinoma (IDC) is diagnosed with or without a ductal carcinoma in situ (DCIS) component. Previous analyses have found significant differences in tumor characteristics between pure IDC lacking DCIS and mixed IDC with DCIS. We will test our hypothesis that pure IDC represents a form of breast cancer with etiology and risk factors distinct from mixed IDC/DCIS. Methods We compared reproductive risk factors for breast cancer risk, as well as family and smoking history between 831 women with mixed IDC/DCIS (n=650) or pure IDC (n=181), and 1,620 controls, in the context of the Women's Circle of Health Study (WCHS), a case-control study of breast cancer in African-American and European-American women. Data on reproductive and lifestyle factors were collected during interviews, and tumor characteristics were abstracted from pathology reports. Case-control and case-case analyses were conducted using unconditional logistic regression. Results Most risk factors were similarly associated with pure IDC and mixed IDC/DCIS. However, among postmenopausal women, risk for pure IDC was lower in women with body mass index (BMI) 25 to <30 kg/m2 (Odds Ratio (OR)=0.66; 95% confidence interval (CI), 0.35-1.23) and BMI≥30 kg/m2 (OR=0.33; 95% CI, 0.18-0.67) compared to women with BMI<25 kg/m2, with no associations with mixed IDC/DCIS. In case-case analyses, women who breastfed up to 12 months (OR=0.55; 95% CI, 0.32-0.94) or longer (OR=0.47; 95% CI, 0.26-0.87) showed decreased odds of pure IDC than mixed IDC/DCIS compared to those who did not breastfeed. Conclusions Associations with some breast cancer risk factors differed between mixed IDC/DCIS and pure IDC, potentially suggesting differential developmental pathways. These findings, if confirmed in a larger study, will provide a better understanding of the development patterns of breast cancer and the influence of modifiable risk factors, which in turn could lead to better preventive measures for pure IDC, which

    Renal Cell Carcinoma (RCC) is notorious for its unpredictable dissemination patterns involving both lymphatic and haematogenous route without a clear-cut preponderance for any. Unlike other intra-abdominal malignancies like colorectal carcinoma, renal cell carcinoma is often known to metastasize to distant sites even after a confident and unsuspecting curative resection or often as the primary presentation constantly adding and agitating our presentation patterns for this sneaky tumour. Presented below is a case of such an unsuspecting female patient. She was referred from the orthopaedic OPD to surgery OPD with a right clavicular swelling which was histopathologically examined and diagnosed as a metastatic renal cell carcinoma following which she was diagnosed with right renal cell carcinoma.

    Muscle invasive urothelial carcinoma has been treated with cystectomy ± adjuvant therapy. Recently, a bladder-sparing protocol has been offered to selected patients closely followed with surveillance biopsies. In this setting, radiation-induced changes (RAD-Ch) may be very difficult to distinguish from carcinoma in situ, and failing to recognize them may lead to overtreatment. We ascertained the role of immunohistochemistry using cytokeratin (CK) 20, p53, and CD44s in bladder biopsies from 28 patients with a history of bladder radiation and 17 with carcinoma in situ without radiation. Negative or weak multifocal nuclear p53 staining was seen in 24 of 28 RAD-Ch cases, whereas strong and diffuse nuclear p53 staining was found in 8 of 17 carcinoma in situ cases and moderate and focal to multifocal in 3. CK20 showed strong cytoplasmic staining of only umbrella cells in 22 of 28 RAD-Ch cases. In contrast, 11 of 17 carcinomas in situ showed diffuse and strong CK20 positivity and 5 moderate and focal to multifocal positivity. All carcinomas in situ with weak or no p53 showed significant CK20 staining except 1. CD44s displayed diffuse membranous positivity in 7 of 17 RAD-Ch cases and up to mid-third in 8. Only 1 of 17 carcinomas in situ had diffuse membranous CD44s staining. Diffuse and significant CK20 expression was seen in most carcinomas in situ. Strong and diffuse p53 expression was only seen in carcinoma in situ (~50%), whereas diffuse CD44s staining was typically only seen in RAD-Ch. Our data suggest that a CK20(-) p53(-) CD44a panel proves to be very helpful (CK20 more reliable than p53 or CD44s) in the diagnosis of RAD-Ch.

    Voriconazole is a treatment for severe fungal infections. Prolonged voriconazole therapy may induce skin reactions, with 1% of severe photosensitivity accidents. Recently the imputability of voriconazole in skin carcinogenesis has been suggested. This report concerns a 55-year-old man suffering from pulmonary aspergillosis who presented a phototoxic reaction a few months after introduction of voriconazole, followed by multiple squamous cell carcinomas of sun-exposed skin areas. After voriconazole discontinuation, no new carcinoma was observed. The detection of EBV and HPV in skin lesions was negative. Exploration of gene mutations involved in skin carcinogenesis showed two variants of the MICR gene. The occurrence of multiple, recurrent, aggressive squamous cell carcinomas is rare with voriconazole, but its imputability is strongly suggested. A plausible hypothesis is that several factors including voriconazole uptake, immunosuppression, and genetic background could explain the phenotype of fast-developing skin carcinomas. Voriconazole therapy should be accompanied by stringent photoprotection and skin monitoring.

    We describe a rare pattern of urothelial carcinoma (UC) invasion consisting of large, irregular to regular nests, with bland cytology. We prospectively retrieved 23 cases of large nested UC from one of the author's consult files (2001 to 2010). The mean patient age was 63.7 years (39 to 89 y), and 86% were men. There were 18 cases with transurethral resection of the bladder, 2 nephroureterectomy specimens, and 3 radical cystectomy (RCs) specimens. A surface component was present in 19 of 23 cases, with 16 low-grade papillary UCs, 2 low-grade papillary UCs with <5% high-grade UC, and 1 high-grade papillary UC. Twenty of 23 cases invaded into the muscularis propria (MP), 2 into lamina propria with no MP present, and 1 into smooth muscle indeterminate between muscularis mucosae and MP. In 21 cases, the invasive component was composed of medium to large nests that varied from rounded circumscribed borders to a stromal-tumor interface with a more irregular ragged appearance. Two showed a verruciform, pushing border into the MP with the nests having central cyst formation. Cytologically, the nuclei lacked significant nuclear atypia, where at most occasional scattered slightly enlarged, hyperchromatic nuclei with small-indistinct nucleoli were noted. Four cases had focal necrosis and 3 cases had more extensive necrosis. The median mitotic count was 1.5 per 10 high-power fields. The stroma surrounding the large nests typically had a mild-to-moderate fibrous and/or inflammatory reaction; 4 cases exhibited no stromal reaction, whereas 2 cases had a moderate-to-marked stromal response. In 7 of 23 cases, conventional patterns of urothelial invasion were identified, 5 of which composed ≤5% of the neoplasm. One case had angiolymphatic invasion. Four cases had subsequent RC specimens available for review. Two of 4 RC specimens had no residual carcinoma (1 with neoadjuvant radiotherapy), 1 had large nested UC in MP, and 1 had mixed large nested UC and focal conventional UC

    Lymphoepithelioma-like carcinomas are distinctive epithelial derived malignant neoplasms that have a syncytial growth pattern and lymphoid stroma. The majority of tumors with this appearance are Epstein Barr virus (EBV)-associated. We report a patient with a clinical presentation concerning for lymphoma who was diagnosed with an EBV-associated pancreatic carcinoma with a lymphoepithelioma-like pattern. Targeted sequencing analysis showed a molecular profile distinct from conventional ductal adenocarcinoma of the pancreas.

    Angiokeratoma including vulvar angiokeratoma is a very rare complication of radiation. Exact incidence is still unknown, we report a case that developed radiation-induced angiokeratoma of skin in the vulvar region along with other late radiation sequelae in the form of bone fracture, new bone formation, bone marrow widening, muscle hypertrophy, and subcutaneous fibrosis, 18 years after radiotherapy to the pelvic region for the treatment of carcinoma cervix. All these late radiation sequel are rare to be seen in a single patient, and none of the case reports could be found in the world literature. PMID:27057045

    Small bowel obstruction (SBO) due to intussusception in adults is a rare condition. Diagnosis at the time of admission is usually challenging. More often than not, a bowel intussusception in adults is secondary to an organic condition, frequently malignancies. Therefore, a surgical approach is indicated most of the times. We report the case of a forty-nine years old lady presenting with a SBO secondary to small bowel metastases with two ileo-ileal intussusceptions, one of which was missed at initial surgical exploration. A giant cell carcinoma of the lung (GCCL) with small bowel metastases was diagnosed subsequently. The case is presented as well as a brief review of literature.

    Transarterial radioembolization (TARE) with yttrium-90 is a minimally invasive locoregional therapy for hepatocellular carcinoma (HCC), and involves selective delivery of glass or resin microspheres impregnated with radioactive yttrium-90 into small arteries preferentially supplying the tumor for tumoricidal effect thus sparing the nontumoral liver, or into lobar artery to induce atrophy and contralateral hypertrophy. Clinically, post-TARE a small proportion of cases develop radioembolization-induced liver disease. Histological changes of TARE on nontumoral liver parenchyma have not been well characterized. Herein, we report two cases of liver resections for HCC post-TARE, and describe the histological changes in nontumoral liver parenchyma.

    Adenosquamous carcinoma of the breast is a rare cancer that develops as glands and tubules admixed with solid nests of squamous cells in a spindle cell background. Furthermore, its occurrence following AML is also rare. To the best of our knowledge, based on a review of the relevant literature, thus far there have not been any welldocumented cases. In the present case report, we report on a middle-aged woman with a 2year history of acute myeloid leukemia (AML) who was admitted to hospital due to a mass in the right breast, with concurrent cutaneous lesions on the breast. The clinical and pathological investigations resulted in the diagnosis of adenosquamous carcinoma of the breast. The patient underwent a modified radical mastectomy (MRM). Subsequently, the patient received chemotherapy, involved-field radiation therapy and target therapy. At 9 months after the final cycle of chemotherapy, and while she was on targeted therapy with trastuzumab (6 mg administered every 3 weeks), the patient presented with extensive dermatomal skin lesions. A biopsy report revealed metastatic lesions of invasive ductal carcinoma in the abdomen, so chemotherapy resumed with a course lasting for 6 cycles, with the identical treatments, but lacking trastuzumab.

    Carcinoma of gall bladder is the most common malignancy of the biliary tract worldwide and is usually associated with poor prognosis. In this era of laparoscopic cholecystectomy, there has been increase in detection of early stage incidental gall bladder carcinoma in cholecystectomy specimens. A retrospective study was carried out in tertiary care hospital in central India. A total of 2990 patients underwent laparoscopic cholecystectomy during the year 2001-2013. Hospital records and histopathology reports of these patients were studied in detail. Twenty three cases of gall bladder carcinoma were detected incidentally accounting for an incidence of 0.76 %. It was more common in females with an M: F ratio of 1:1.9. Mean age of presentation was 57.8 years. Gall stones were present in 22 cases and one patient presented with features of acute cholecystitis. Three patients had associated xanthogranulomatous inflammation and 10 had associated intestinal metaplasia. It is not uncommon to encounter incidental malignancies of gall bladder in laparoscopic cholecystectomy specimens sent to histopathology for presumably benign disease. Histopathology reports must include comments on extent of infiltration, perineural invasion, tumor differentiation and nodal involvement for oncologist information and subsequent management of patients.

    The aim of the present study was to report the case of a patient with recurrent myoepithelial carcinoma of the submandibular gland without progression for five years following treatment. A 71-year-old male patient presented to hospital with a painless swelling in the region of the right submandibular gland, and received a radical neck dissection on January 29, 2008. A nodule of ~7×4×2 cm was identified at the site of the right submandibular gland, and the pathological results revealed a diagnosis of myoepithelial carcinoma of the right submandibular gland with no lymph node metastasis. However, this case developed local recurrence with wide-spread metastasis in the lungs. Between April and October 2008, the patient underwent several treatment regimens and demonstrated no improvement following 6 cycles of chemotherapy. From then on, the patient was treated with recombinant adenoviral-p53 (rAd-p53) combined with radiotherapy using a 6 millivolt medical linear accelerator. The foci were relieved and the cancer demonstrated no signs of progression during the 5-year follow-up. rAd-p53 combined with radiotherapy was useful for treating myoepithelial carcinoma of the submandibular gland.

    Background. Longitudinally extensive transverse myelitis (LETM) is characterized by spinal cord inflammation extending vertically through three or more vertebral segments. The widespread use of MRI revealed LETM more frequency than ever. We report the case of a patient with pathologically confirmed small-cell lung carcinoma metastasis into the spinal cord presenting as LETM. Case Presentation. A 74-year-old man developed rapidly progressive sensorimotor disturbance and vesicorectal dysfunction. T2-weighted magnetic resonance imaging of the spine revealed LETM at the level of from T3 to conus medullaris; gadolinium enhancement showed concurrent tumor in the thoracic spinal cord from T10 to T11. Systemic survey identified a nodular mass in the lung that was verified as small-cell carcinoma. Following initial failed treatment by high-dose steroid, the patient underwent an emergent microsurgical tumor resection. Histological examination was identical with the lung carcinoma. The patient died of tumor progression at the 47th day after admission. At autopsy, only changes of edema were found in the gray matter of the cord, while tumor cells were not noted in it. Conclusion. Metastasis may rarely present symptoms of LETM. Prompt identification of underlying etiology by contrast examination and systemic survey is crucial for the patient assumed as LETM. PMID:24455343
