    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.

    Two hundred and fifty men admitted to a thoracic surgical centre and matched controls were questioned in detail about their occupations after leaving school and their smoking habits. Of 201 men with confirmed bronchial carcinoma 58 gave a history of occupational exposure to asbestos, whereas only 29 out of 201 men matched for age and residential area who were admitted with other diseases gave such a history. This difference was statistically highly significant. The usual association of bronchial carcinoma with heavy smoking was observed, but asbestos exposure increased the risk of carcinoma whatever the level of smoking. These results are consistent with the hypothesis that asbestos exposure and the level of smoking act independently in causing bronchial carcinoma. The patients with carcinoma who had been exposed to asbestos presented on average three years earlier than those who had not been exposed. Asbestos regulations have eliminated the risk of exposure to workers in scheduled industries, so asbestos-induced diseases will probably be increasingly found among the many workers who have had incidental exposure to asbestos. It is therefore important to take a full occupational history. PMID:856382

    Bronchogenic cysts originate from abnormal budding of the tracheal diverticula during the embryological period. Inaccuracy in the process of growing of the ventral foregut will give rise to bronchogenic cyst. Scapular bronchogenic cyst is an extremely rare form of this anomaly. A three years old boy suffered for 2 years with left sided suprascapular cystic lesion which was gradually increasing in size. The swelling was 4 × 3 cm in size and non tender. The cyst was evaluated by CT scan that showed complex cystic lesion over the left scapular spine. Total excision of the cyst was done and histopathology showed cutaneous bronchogenic cyst. The proposed mechanism for such cutaneous lesion is that the accessory buds from the tracheobronchial tree/primitive foregut migrated from the thorax in an aberrant manner to lie in periscapular positions. The definitive treatment of scapular lesions is total surgical excision. The final diagnosis is based on the histopathological findings in the majority of cases. PMID:22496944

    To define methods for lymph node staging and the absence of nodal involvement (pN0) during surgery for bronchogenic carcinoma (BC). Review of previous definitions of the Bronchogenic Carcinoma Cooperation Group of the Spanish Society of Pneumology and Chest Surgery (GCCB-S), and a comparison with the international literature; proposal of new definitions agreed upon by the GCCB-S. Methods for intraoperative lymph node evaluation proposed are as follows: not performed; biopsy (biopsy or removal of nodes with no intention of sampling all nodal stations); sampling (removal of nodes of a pre-established number of nodal stations, including at least the paratracheal, subcarinal and hilar stations); systematic nodal dissection (SND) (excision of all nodes from stations on the operated side); extended nodal dissection (removal of contralateral pulmonary and mediastinal nodes as a complement to SND); and miscellaneous, for other forms of intraoperative staging. The proposed definition for pN0 is removal of at least six lymph nodes, pathology of all N1 locations, removal of lymph nodes from right superior and inferior paratracheal and subcarinal stations for right lung tumors, removal of subcarinal nodes for left lung tumors, removal of subaortic and anterior mediastinal nodes for tumors of the left upper lobe, and removal of paraesophageal and pulmonary ligament nodes for tumors of lower lobes. The new definitions encompass the current forms of intraoperative evaluation of BC and avoid the inaccuracies of previous definitions from the GCCB-S.

    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.

    Bronchogenic cyst is a malformation of the ventral portion of the intestine, which is limited by bronchial epithelium and produces alterations in the development of the tracheobronchial tree. They may be single or multiple, and are usually confined to one lung or to the mediastinum, rarely to the neck, which is a subcutaneous tissue. The case of a 9 year old girl is reported, who presented with a clinical picture characterized by a slow-growing, asymptomatic tumour on the left side of the neck of 4 years onset. Chest X-ray, neck ultrasound and computed tomography of the neck and chest ruled out any other injury. A complete resection was performed, and the histopathological study confirmed the diagnosis of bronchogenic cyst. The symptomatology of a bronchogenic cyst is due to the compression of the vascular, digestive or air structures, as well as its size, infection and location. The treatment of choice is a surgical resection, even when asymptomatic. Copyright © 2015 Academia Mexicana de Cirugía A.C. Published by Masson Doyma México S.A. All rights reserved.

    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.

    Bronchogenic cyst is a rare congenital malformation and commonly located in the mediastinum and lung parenchyma. To determine the clinical characteristics of the patients with diagnosis of bronchogenic cysts, their location and the infectious bacteria when the cysts are infected. The cases were collected from 1 January 2005 to 1 January 2013, in a third level hospital. The cases with bronchogenic cysts resected by thoracotomy were confirmed by histological study. Age, sex, admission diagnosis, location, size, imagenologic studies, and bacteriological cultures were evaluated. Of the 12 cases with diagnosis of bronchogenic cysts surgically resected by thoracotomy, six were male and six female, with 50% located in lung parenchyma and 50% in mediastinum, one of the latter was para-oesophageal. Bacteriological study of the cystic content demonstrated bacterial infection in seven (58%) cases. Bronchogenic cysts are rare congenital benign lesions. They must be resected because their content might be infected. The histopathology study is necessary to confirm the diagnosis, together with bacteriological examination. Thoracotomy is a safe procedure to resect bronchogenic cysts. Copyright © 2015 Academia Mexicana de Cirugía A.C. Published by Masson Doyma México S.A. All rights reserved.

    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

    In order to improve our understanding of the role of postoperative radiotherapy and to search for new strategies in the management of N/sub 1/, N/sub 2/, T/sub 3/ stage carcinoma of the lung, we analyzed results of treatment in 148 of 166 patients who were registered at the Massachusetts General Hospital Tumor Registry from 1971 to 1977 with a pathological diagnosis of N/sub 1/, N/sub 2/, T/sub 3/ carcinoma of the lung after pulmonary resection. Ninety-three patients received postoperative radiotherapy and another 55 were followed without further treatment. Patients with adenocarcinoma showed significant improvement of survival by postoperative radiotherapy; actuarial NED (no evidence of disease) survival rates were 85% and 51% at 1 year, and 43% and 8% at 5 years for S + RT (patients treated with surgery plus postoperative radiotherapy) and S (patients treated with surgery only) groups, respectively, (P < 0.01). The brain was the most common site of failure in adenocarcinoma, 53% and 58% of all failures occurred in the brain in S and S + RT groups suggesting elective whole brain irradiation in a future trial. For the squamous cell carcinoma group, there was no improved survival in the irradiated patients, actuarial NED survival rates were 63% for both S + RT and S groups at 2 years, and 42% and 33% for S + RT and S groups at 4 years. These figures should be considered in the light of the following: In 52% (24/46) of S + RT vs. 27% (8/29) of S group, disease was in N/sub 2/, T/sub 3/ stages. Regional recurrence was the most common failure in squamous cell carcinoma; 76% (13/17) and 45% (10/22) of all failures were in the regional area in S and S + RT groups. Regional failure in S + RT group was noted with radiation dose up to 5000 rad (TDF 82) which suggests radiation dose higher than 5000 rad in future trial.

    Objective Bronchogenic Carcinoma Can Mimic Or Be Masked By Pulmonary Tuberculosis (Tb), And The Aim Of This Study Was To Describe The Radiologic Findings And Clinical Significance Of Bronchogenic Carcinoma And Pulmonary Tb Which Coexist In The Same Lobe. Materials and Methods The findings of 51 patients (48 males and three females, aged 48-79 years) in whom pulmonary TB and bronchogenic carcinoma coexisted in the same lobe were analyzed. The morphologic characteristics of a tumor, such as its diameter and margin, the presence of calcification or cavitation, and mediastinal lymphadenopathy, as seen at CT, were retrospectively assessed, and the clinical stage of the lung cancer was also determined. Using the serial chest radiographs available for 21 patients, the possible causes of delay in the diagnosis of lung cancer were analyzed. Results Lung cancers with coexisting pulmonary TB were located predominantly in the upper lobes (82.4%). The mean diameter of the mass was 5.3 cm, and most tumors (n=42, 82.4%) had a lobulated border. Calcification within the tumor was seen in 20 patients (39.2%), and cavitation in five (9.8%). Forty-two (82.4%) had mediastinal lymphadenopathy, and more than half the tumors (60.8%) were at an advanced stage [IIIB (n=11) or IV (n=20)]. The average delay in diagnosing lung cancer was 11.7 (range, 1-24) months, and the causes of this were failure to observe new nodules masked by coexisting stable TB lesions (n=8), misinterpretation of new lesions as aggravation of TB (n=5), misinterpretation of lung cancer as tuberculoma at initial radiography (n=4), masking of the nodule by an active TB lesion (n=3), and subtleness of the lesion (n=1). Conclusion Most cancers concurrent with TB are large, lobulated masses with mediastinal lymphadenopathy, indicating that the morphologic characteristics of lung cancer with coexisting pulmonary TB are similar to those of lung cancer without TB. The diagnosis of lung cancer is delayed mainly because of

    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.

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

    Primary lung tumors are rare in children, and mucoepidermoid carcinoma (MEC) represents less than 10% of them. Additionally, MEC arising from bronchogenic cysts (BC) is particularly unusual. We describe the clinical and genetic findings on a MEC occurring within a previous location of a BC in an adolescent. This particular association has not been previously reported. The lesion revealed normal karyotype without the typical t(11;19)(q21;p13) translocation. Cyclin D1 overexpression (165-fold increase) was demonstrated by real-time PCR although FISH assessment showed normal hybridization at 11q13. Information on these unusual clinical presentations may present relevant insight on tumorigenesis of infrequent pediatric pulmonary tumors.

    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.

    Bronchogenic cysts occurring in the left ventricle are a medical rarity. One successfully operated case is reported herein. The location of the cyst was just between the epicardium and myocardium of the inferior left ventricular wall, adjacent to the apex of the heart. Complete excision was achieved through a left anterolateral thoracotomy without extracorporeal circulation.

    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.

    Spinal bronchogenic cysts are rare findings, with only four cases of lumbar bronchogenic cysts reported in the literature. All of these bronchogenic cysts involved the conus medullaris. We present the first case of a lumbar bronchogenic cyst and arachnoid cyst arising from the cauda equina in a 68-year-old male. Uniquely, this bronchogenic cyst also contained components of an arachnoid cyst. Magnetic resonance imaging (MRI) demonstrated a compressive cystic lesion at the level of the L3 vertebra splaying the cauda equina. An L3/L4 laminectomy was performed with marsupialisation of the cyst. Histological examination revealed pseudostratified ciliated columnar epithelium confirming the diagnosis of a bronchogenic cyst, as well as a pleated fibrovascular tissue lined by sparsely spaced small monomorphic arachnoidal cells, indicating an arachnoid cyst. We demonstrate that bronchogenic cysts can be successfully treated with marsupialisation.

    Fourteen patients with small cell bronchogenic carcinoma, five with extensive disease and nine with localized disease, were treated with cyclophosphamide (1.5 g/m2 iv, Days 1 and 22), lomustine (70 mg/m2 orally, Day 1), and methotrexate (15 mg/m2 twice weekly during Weeks 2, 3, 5, and 6). UHBI (600 rads) was given during Week 6 in a single dose and LCI was given during Week 7 (2000 rads/five fractions) to the tumor and mediastinum. Maintenance chemotherapy began in Week 12 with cyclophosphamide (700 mg/m2 iv every 3 weeks) and lomustine (70 mg/m2 orally every 6 weeks). Twelve patients were evaluable for response and toxicity (eight with limited disease). There were three complete response and seven partial responses after induction chemotherapy. After completion of the consolidation radiation therapy, all 12 patients had a response: six complete responses and six partial responses. Acute toxic effects included nausea and vomiting in eight patients, fever in five, and hypotension and angina in one. Subacute toxic effects included nausea, vomiting, and dehydration in two patients who required hospitalization, prolonged aplasia in one, reversible radiation esophagitis in three. Three patients had radiation pneumonitis including one with bilateral diffuse disease that led to death from respiratory failure. Only two of 12 patients received their maintenance therapy on schedule. Treatment failures occurred within the LCI field in seven patients and in distant metastatic sites in six. The median time to first relapse was 7 months and the median survival was 9 months. Because of toxicity, treatment delays, and poor survival in this group of patients, we cannot recommend this combined modality approach.

    We studied the efficacy of cisplatin-based polychemotherapy for non-small-cell lung cancer. One hundred nineteen patients with adenocarcinoma or large cell carcinoma were randomized to receive cyclophosphamide, adriamycin, cisplatin and mitomycin C (CAPM) or mitomycin C, cytosine arabinoside and tegafur (MCT), and 48 patients with squamous cell carcinoma were randomized to receive cisplatin, adriamycin and peplomycin (PAP) or mitomycin C, cyclophosphamide, tespamine, toyomycin and tegafur (MCTTT). Radiation was given to the chest in patients with stage I-III disease. The response rates were CAPM, 34.5%; MCT, 13.1% (p less than 0.01) and PAP, 63.3%; MCTTT, 42.3%. A significant difference in response rate between the CAPM and MCT regimens was observed only in stage IV patients and not in stage I-III patients. The median survival was 9.5 months in the CAPM arm vs. 6.5 months in the MCT arm (p less than 0.007), and 8.5 months in the PAP arm vs. 6.5 months in the MCTTT arm. Improved median survival for the CAPM regimen was noted only in stage IV patients and not in stage I-III patients when compared to patients given the MCT regimen, respectively. Nausea and vomiting were significantly increased in patients with cisplatin-based polychemotherapy. Myelosuppression was more severe with the CAPM regimen than with the other chemotherapy regimens. We concluded that cisplatin-based polychemotherapy, CAPM and PAP therapy were of more benefit to patients with disseminated non-small-cell lung cancer than MCT and MCTTT therapy.

The possibility of such a cyst should not be excluded because of a high CT number, which reflects the turbid contents of the cyst.

Carcinoma was the indication in 143 and other tumors in 15 cases. Histology and staging conditions are outlined. The importance of the intraoperative histological or cytological examination of the resection margin is emphasized. One-hundred and twenty operations were performed on the right and 38 on the left side. In 12 cases of semimalignant or benign tumors, bronchoplasty without lung resection was carried out. The use of a wedge bronchoplasty instead of the customary sleeve resection is discussed. Right lower sleeve lobectomy with replantation of the middle lobe is described. Mortality was 6.3%. Fifty-six patients were alive more than five years later (35.4%). Forty-six of them were operated upon for carcinoma which corresponds to a 32% five years survival.

    Controversy persists as regards the indications and results of surgery in the treatment of patients with stage pIIIA-N2 non-small cell lung cancer (NSCLC). The objective of this study was to analyze the overall survival of a multicentre series of these patients and the role of adjuvant treatment, looking for factors that may define subgroups of patients with an increased benefit from this treatment. A retrospective study was conducted on 287 patients, with stage pIIIA-N2 NSCLC subjected to complete resection, taken from a multi-institutional database of 2.994 prospectively collected consecutive patients who underwent surgery for lung cancer. Adjuvant treatment was administered in 238 cases (82.9%). Analyses were made of the age, gender, histological type, administration of induction and adjuvant chemotherapy and/or radiation therapy treatments. The 5-year survival was 24%, with a median survival of 22 months. Survival was 26.5% among patients receiving with adjuvant treatment, versus 10.7% for those without it (P=.069). Age modified the effect of adjuvant treatment on survival (interaction P=.049). In patients under 70 years of age with squamous cell carcinoma, adjuvant treatment reduced the mortality rate by 37% (hazard ratio: 0,63; 95% CI; 0,42-0,95; P=.036). Completely resected patients with stage pIIIA-N2 NSCLC receiving adjuvant treatment reached higher survival rates than those who did not. Maximum benefit was achieved by the subgroup of patients under 70 years of age with squamous cell carcinoma. Copyright © 2012 AEC. Published by Elsevier Espana. All rights reserved.

    We hereby report a case on bronchogenic cyst which is initially non-infected, then becomes infected after bronchoscopic ultrasound (US)-guided transesophageal fine-needle aspiration (FNA). The non-infected bronchogenic cyst appears to be filled with relatively echogenic materials on US, and the aspirate is a whitish jelly-like fluid. Upon contrast-enhanced MRI of the infected bronchogenic cyst, a T1-weighted image shows low signal intensity and a T2-weighted image shows high signal intensity, with no enhancements of the cyst contents, but enhancements of the thickened cystic wall. The patient then undergo video-assisted thoracic surgery 14 days after the FNA. The cystic mass is known to be completely removed, and the aspirate is yellowish and purulent. To understand the image findings that pertain to the gross appearance of the cyst contents will help to diagnose bronchogenic cysts in the future. PMID:24624219

    An unusual case is presented of a tourist who developed fatal cerebral air embolism, pneumomediastinum and pneumopericardium while ascending from low altitude to Europe's highest railway station. Presumably the air embolism originated from rupture of the unsuspected bronchogenic cyst as a result of pressure changes during the ascent. Cerebral air embolism has been observed during surgery, in scuba diving accidents, submarine escapes and less frequently during exposure to very high altitude. People with known bronchogenic cysts should be informed about the risk of cerebral air embolism and surgical removal should be considered. Cerebral air embolism is a rare cause of coma and stroke in all activities with rapid air pressure changes, including alpine tourism, as our unfortunate tourist illustrates.

    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

    Among 1,855 thoracic neoplasms seen from 1971 to 1990, there were 923 with bronchogenic carcinoma (CaBr), 50%. The relation male:female was 1.95:1. Sixty three period thirty one percent were male. The histologic type were epidermoid 32.2%, adenocarcinoma 28.4% and small cells 13.2% in men; in women adenocarcinoma 38.9%, epidermoid 28.9% and mixed 7.7% with a significative difference for both sexes for these neoplasms. Other types were less frequent. There is significative difference between smokers and non smokers of both sexes p < 0.001. Epidermoid, adenocarcinoma, small cells, large cells and mixed were the most frequent in male smokers, in women these varieties were more frequent in nonsmokers. Comparison with the reference group with no CaBr suggests that epidermoid, adenocarcinoma and small cells carcinomas have a great possibility to be found in male smokers. Ninety two period two percent of cases were stage III (Tumor Node MetastasIs) with no chance for radical treatment. Only 94 were subject to surgery with 36 total resections. CaBr is an important problem in the General Hospital of Mexico. Antismoking programmes must be stressed in relation to the frequency of CaBr in smokers.

    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.

    Myoepithelial carcinoma is an uncommon malignant salivary gland neoplasm with a predilection for parotid gland. However, its occurrence in minor salivary glands is considerably less with only 28 cases being reported in the literature. We report a case of myoepithelial carcinoma of palate in a 50-year-old woman. Computed tomography and magnetic resonance imaging revealed an extensive lesion in the palate. Microscopically, the tumor exhibited a wide spectrum of cytomorphologic features that overlap with other salivary gland tumors. Immunohistochemistry served as an adjunct in the diagnosis of the lesion. Clinical, radiographic, and histopathologic correlation along with immunohistochemical profile enabled to arrive at a diagnosis of myoepithelial carcinoma.

    Bronchogenic cyst (BC) is congenital abnormality of the tracheobronchial bud derived from the primitive foregut which is predominantly found in the mediastinum. Surgery remains the most common treatment when malignancy is suspected, or when there are presenting. Only infrequently, is BC located at an extrathoracic site. Although rarely located in the stomach, BC should be considered as a differential diagnosis of gastric neoplasm. For these cases, surgery remains a common choice. Minimally invasive procedures such as endoscopic ultrasonography-guided fine needle biopsy aspiration (EUS-FNA) and endoscopic submucosal dissection (ESD) should also be considered when the diagnosis of BC is suspected. They are valuable diagnostic methods that can assess and identify the location of the lesion, and facilitate histological examination of the cyst. In some cases of more superficial lesions ESD can take the place of surgery as it avoids unnecessary complications of a more invasive procedure. Here we present a case of gastric BC located in the fundus of the stomach that resembled a gastrointestinal stromal tumor (GIST). We discuss its embryology, pathogenesis, radiological, clinical and treatment modalities. We also provide a thorough review of 14 cases (including our own case), which completely meet pathological criteria has been undertaken focusing on symptom, location, treatment, and histological features.

    The coexistence of pancreatic carcinoma with severe form of acute pancreatitis (AP) is not only an extremely rare phenomenon described in literature but also a real problem in the aspect of differential diagnostics of neoplastic and inflammatory morphological changes in this organ. The study objective was the analysis of clinical material obtained from patients with inflammatory and neoplastic lesions, treated surgically in I Department of General and Endocrinological Surgery, Medical University of Bialystok in the years 1980-2005. Of these patients, 7 had pancreatic carcinoma at various stages of advancement diagnosed in the late postoperative period after severe form of AP. Patients' history, physical examination as well as biochemical tests and imaging diagnostic procedures (ultrasonography, CT) of the abdominal cavity explicitly showed severe form of acute pancreatitis. In every case, CA19-9 antigen values were substantially elevated (mean 780 +/-325 IU/ml, norm 0-37 IU/ml). Histopathological analyses of samples collected during laparotomy revealed the presence of necrotic-purulent tissues. In the late postoperative period, i.e. 3-24 months, all these patients were reoperated on for pancreatic carcinoma or its metastases. Only in one case, radical Whipple surgery was performed. All the remaining patients underwent palliative procedures or samples for histopathological examinations were only collected. In all the seven cases, metastatic carcinoma was diagnosed, including pancreatic carcinoma in 6 patients. These observations seem to indicate that severe AP may be insidiously accompanied by pancreatic carcinoma and that this coexistence should always be taken into consideration.

    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

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.

    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.

    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.

    Adenoid basal carcinoma (ABC) is a rare epithelial tumor of the cervix. It makes up approximately 1% of all cervical adenocarcinomas. Rare cases have been associated with common cervical epithelial tumors. We present a case of ABC associated with typical squamous cell carcinoma. A 54-year-old post-menopausal woman underwent D&C for vaginal bleeding. Histologically, the tumor was characterized by small cells with a narrow cytoplasm, making up islands and cords. Peripheral palissading in the cells surrounding the cystic areas that contained central cellular debris and keratin was noted. The patient underwent total hysterectomy, bilateral salpingo-oophorectomy, pelvic lymphadenectomy and omentectomy. Large cell keratinized type squamous cell carcinoma areas in the cervix were noted besides the limited ABC areas. After surgery, the patient was treated with radiation therapy. A retroperitoneal metastasis was found on the first year and chemotherapy was administered. The patient has no evidence of disease 27 months after the first diagnosis. ABC makes up quite a rare group of cervical cancers and should be kept in mind during the evaluation so that a differentiation can be made with tumors with similar morphology as it can show various histological patterns, and can be seen together with more aggressive cancers.

    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

    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.

    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.

    In 87 patients with histologically proven bronchogenic carcinoma, computerised tomography (CT) and bronchoscopy were performed to assess the accuracy of CT in detecting bronchial stenosis. Whereas patent airways and mainstem stenosis were recognised in 85% of the cases, the overall accuracy was only 57%. Furthermore, the results of both methods were compared to scintigraphy (ventilation, perfusion) to evaluate the functional impairment due to altered lung morphology and bronchial stenosis. With an increasing number of CT-diagnosed atelectatic or infiltrated segments an almost linear decrease in ventilation and perfusion values was observed. In comparison, bronchoscopy-diagnosed tumour stenosis resulted in decreased ventilation and perfusion data only if the lesion was centrally located.

    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.

Experience in lung transplant for patients with lung carcinoma has shown that select patients may benefit from this therapy. In this report, we examine the case of a bilateral lung transplant in a young man with bilateral bronchioloalveolar carcinoma. This report suggests that bilateral lung transplant might be an efficient therapeutic option for select patients with lung carcinoma.

  5. Case Report: Multifocal biphasic squamoid alveolar renal cell carcinoma

    A multifocal biphasic squamoid alveolar renal cell carcinoma in a 68-year-old man is reported. Four different peripheral tumor nodules were identified on gross examination. A fifth central tumor corresponded to a conventional clear cell renal cell carcinoma. Biphasic squamoid alveolar renal cell carcinoma is a rare tumor that has been very recently characterized as a distinct histotype within the spectrum of papillary renal cell carcinoma. Immunostaining with cyclin D1 seems to be specific of this tumor subtype. This is the first reported case with multifocal presentation. PMID:27158455

    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.

    This study aims to present the clinical features and treatment of a case of maxillary ameloblastic carcinoma. Ameloblastic carcinoma is a rare malignant odontogenic carcinoma that has metastatic potential. Due to its rare incidence, there are few studies focusing on its radiological characteristics. When ameloblastic carcinoma demonstrates an aggressive appearance, it may be diagnosed as a malignant tumor; however, in cases showing a non-aggressive appearance, it is difficult to distinguish ameloblastic carcinoma from ameloblastoma. We report a case of ameloblastic carcinoma of the maxilla in a 59-year-old male patient, including the clinical signs, radiological images and pathological features. A partial area was surgically excised under local anesthesia and the material was sent to the Laboratory of Oral Pathology. The histological sections revealed a fragmented odontogenic tumor of epithelial origin, consisting of solid parenchyma and also revealed basal cells resembling ameloblasts, occasionally arranged in palisades. Certain parts of the architecture resembled that of an ameloblastoma; however, the cytology of other areas confirmed the diagnosis of ameloblastic carcinoma of the maxilla. The patient was scheduled for definitive surgery, including a right maxillectomy and radiotherapy. The patient was followed up every 3 months. After 2 years follow-up, there were no clinical or radiological signs of recurrence. PMID:23205126

    A 49-year-old lady presented with multiple recurring painful lesions over her thighs, arms, and back. Past medical history included a left sided nephrectomy for renal cell carcinoma and a hysterectomy for multiple uterine fibroids (leiomyomas). Histopathological examination revealed changes consistent with pilar leiomyomas. Gene mutation analysis confirmed a diagnosis of hereditary leiomyomatosis and renal cell carcinoma. Hereditary leiomyomatosis and renal cell carcinoma is an uncommon autosomal dominant condition characterised by the concurrent presentation of cutaneous and uterine leiomyomas. Renal cell carcinoma associated with this condition is more aggressive and a significant cause of mortality. Due to this association with potentially fatal renal cell carcinoma we felt that it was important to highlight this case with an update on pathophysiology and management. PMID:27144040

    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.

    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.

    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.

    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.

    Bronchial tumors are rare in children. Most of them are malignant, being the carcinoid tumor the most common. Less frequently the mucoepidermoid carcinoma is found in the tracheobronchial tree. Mucoepidermoid carcinoma accounts for 0.1 to 0.2% of all malignant bronchopulmonary tumors. It manifests with symptoms of airway obstruction and/or recurrent pneumonias. Early diagnosis and appropriate treatment are of great importance in the prognosis. Bronchoscopy with biopsy of the endobronchial mass is the method of choice to confirm the diagnosis. Treatment consists of surgical resection of the lesion. We present an 11-year-old girl with dyspnea on exertion and cough due to a low malignant mucoepidermoid arcinoma of the ronchi. We describe the clinical manifestations, the diagnostic methods and the treatment of this rare neoplasia in pediatrics. Sociedad Argentina de Pediatría.

    Penile verrucous carcinoma is a rare, well-differentiated and low-grade tumor. The surgeons are deficiently aware about the biological behavior and the clinicopathological characteristic of this disease, which raises difficulties during the treatment. In our present study, the clinical and pathological data of 11 patients with penile verrucous carcinoma, aged between 49 to 85 years was retrospectively analyzed. The tumors exhibited exophytic, papillary, caulifower-like or verrucose lesions of great dimensions measuring between 2 to 10 cm on the penises. The tumors were located at glans in 6 cases, invaded the coronoid sulcus in 4 cases and invaded the shaft of the penis in 1 case. Eight cases underwent partial penectomy, while the other 3 were treated with local excision. The diagnosis of penile verrucous carcinoma was confirmed by histopathologic examination of the specimens with the negative surgical margins in all the cases. Within the period of 12 to 60 months of follow-up, all the patients were disease-free with no case of recurrence and metastasis. The novel knowledge and experience of the treatment of penile verrucous carcinoma will be a useful clinical guide for surgeons in the future. PMID:22346275

    The accessory parotid gland is salivary gland tissue separated from the main gland at a variable distance. This gland is histologically similar to the main gland, but has a higher incidence of malignant neoplasms than the main gland. Regarding the various malignant neoplasms, studies have shown higher incidences of mucoepidermoid carcinoma, with less than 2% being adenoid cystic carcinoma. We present a case of swelling in the midcheek region that, after clinical examination, was diagnosed as a case of neoplasm of the accessory parotid gland. On the basis of auxiliary investigations including intraoperative frozen section, it was concluded that it was adenoid cystic carcinoma, grade I, and after wide surgical resection, the tumor was removed without undergoing superficial parotidectomy. The patient received postoperative radiotherapy (RT) and was followed for 14 months without any recurrence or substantial facial asymmetry.

    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.

    We present the case of a 51-year old man with drug-resistant pneumonia in the upper right lobe, weight loss and a 50-pack year history of cigarette smoking who underwent bronchoscopy. By clinical and radiological findings bronchogenic cancer was assumed. Fiberbronchoscopy showed an exophytic tumor-like mass obliterating the right upper lobe. Biopsies revealed an epithelial pseudopapillomatous tumor with multiple mucosal dysplasia and metaplasia. A second bronchoscopy in order to remove the lesion revealed a foreign body embedded in the tissue which could be removed easily. The foreign body proved to be a cherry stone, after its removal pneumonia resolved completely. In the same patient this lesion was recurrent one year later after aspiration of a grape seed. We present this case to emphasize the relationship between foreign body aspiration and inflammatory pseudopapilloma as a sequela of the inflammatory insult provoked by foreign bodies. Bronchoscopy is mandatory and may obviate misdiagnosis and thoracotomy. The use of inhaled and systemic steroids can be used to facilitate successful endoscopic extraction.

  18. A Phase I Study of Light Dose for Photodynamic Therapy (PDT) Using 2-[1-hexyloxyethyl]-2 devinyl Pyropheophorbide-a (HPPH) for Treatment of Non-small Cell Carcinoma in situ or Non-small Cell Microinvasive Bronchogenic Carcinoma. A Dose Ranging Study

    Introduction We report a phase I trial of photodynamic therapy (PDT) of carcinoma-insitu (CIS) and microinvasive cancer (MIC) of the central airways with the photosensitizer (PS) 2-[1-hexyloxyethyl]-2-devinyl pyropheophorbide-a (HPPH). HPPH has the advantage of minimal general phototoxicity over the commonly used PS porfimer sodium (Photofrin®). Methods The objectives of this study were 1) to determine the maximally tolerated light dose at a fixed PS dose and 2) to gain initial insight into the effectiveness of this treatment approach. Seventeen patients with 21 CIS/MIC lesions were treated with HPPH with light dose escalation starting from 75 J/cm2 to 85, 95,125, and 150 J/cm2 respectively. Follow-up bronchoscopy for response assessment was done at one and six months, respectively. Results The rate of pathological complete response (CR) was 82.4% (14/17 evaluable lesions; 14 patients) at one-month and 72.7% (8/11 lesions; 8 patients) at 6 months. Only 4 patients developed mild skin erythema. One of the three patients in 150 J/cm2 light dose group experienced a serious adverse event. This patient had respiratory distress due to mucus plugging, which precipitated cardiac ischemia. Two additional patients treated subsequently at this light dose had no adverse events. The third sixth patient in this dose group was not recruited and the study was terminated because of delays in HPPH supply. However, given the observed serious adverse event, it is recommended that the light dose not exceed 125J/cm2. Conclusions PDT with HPPH can be safely used for the treatment of CIS/MIC of the airways, with potential effectiveness comparable to that reported for porfimer sodium in earlier studies.

    Merkel cell carcinoma was first described by Toker in 1972. It is an uncommon, primary neuroendocrine skin carcinoma which appears in the dermoepidermic area, grows fast, is very aggressive and has a poor prognosis. The aim of this work is to highlight the importance of this tumour, which develops mainly in the skin of the head and neck area, and whose prevalence has increased in recent years. We gathered data on 16 patients suffering cutaneous neuroendocrine carcinoma treated at our hospital between September 12, 1991 and July 13, 2012. We indicated the age and gender of patients. We described the area where the tumour was located, indicating the size in millimetres, according to the major axis of the lesion. Most of the patients studied were over 70 years old, except for one who was 55. The highest frequency of cases appeared among patients aged over 80 years. In the cases studied, when the tumour appeared in the head and neck region (10/16), its location could be nasal-lateronasal, cheek-malar, upper eyelid, frontal or mandibular. The major axis of the lesion ranged between 7 and 35 mm. Unlike with epidermoid or basocellular carcinomas, recurrence and ganglionar metastases were common. Immunohistochemical (CK20) tests are essential for a correct diagnosis. Treatment is usually surgical and occasionally followed by radiotherapy and chemotherapy. This carcinoma is not a very common skin tumour. It appears in old age, in the head and neck region in 50% of cases and often leads to exitus. Copyright © 2013 Elsevier España, S.L.

    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

    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.

    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.

    NUT midline carcinoma (NMC) is a rare, lethal form of differentiated squamous cell carcinoma characterized by chromosomal rearrangement of the NUT gene. Its highly aggressive nature commonly leads to unresectable and metastatic lesions. We report on a case of endobronchial NMC in a middle-aged man who was treated by bronchoscopic electrocautery followed by Ewing sarcoma-based chemotherapy with concurrent chemoradiotherapy. The patient's disease continued to be stable 31 months after diagnosis. NMC is a challenging disease entity, which is difficult to diagnose and treat, and has a dismal overall survival. Most cases of NMC are widely metastatic or unresectable when diagnosed. This is the first reported case that involves intraluminal tumour growth of NMC and demonstrates the effectiveness of early intensive local therapy aided by bronchoscopic techniques.

    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.

    Adenoid cystic carcinoma of the breast constitutes approximately 0.1% of all breast tumors. They can be located in the trachea, bronchus, cervix, lacrimal gland, and skin as well as the breast. Tumors in the breast have better prognoses compared to those in other locations. The diagnosis and treatment planning of this tumor is challenging due to its rare incidence. In this article, we presented a case that was diagnosed with adenoid cystic carcinoma of the breast upon pathology evaluation. A 59-year-old female patient was admitted to our clinic due to a mass in her right breast. Her mammography revealed a 1 cm in diameter mass in the upper outer quadrant of the right breast, which was classified as BIRADS 4C (Breast Imaging Reporting and Data System). On magnetic resonance imaging (MRI) the lesion was also reported as BIRADS 4C. The patient underwent breast conserving surgery (BCS), and the pathology result was reported as adenoid cystic carcinoma of the breast. The patient received chemo-radiotherapy in the postoperative period. Adenoid cystic carcinoma of the breast has been first described in the salivary glands. They can be confused with benign lesions both on physical and radiological examinations. Sentinel lymph node biopsy (SLNB) can be used since axillary metastases are rare. Local recurrence and distant metastases are also very rare. Usually, BCS followed by radiotherapy is adequate to obtain local control. In selected patients with a poor prognosis, chemotherapy and hormonal therapy should be added to the treatment.

    Activation of protooncogenes and inactivation of putative tumor suppressor genes are genetic lesions considered to be important in lung carcinogenesis. Fifty-four cases of non-small-cell lung cancer (23 adenocarcinomas, 23 squamous-cell carcinomas, and 8 large-cell carcinomas) were examined for loss of DNA sequences at 13 polymorphic genetic loci. Loss of heterozygosity was seen more frequently in squamous-cell carcinoma than in adenocarcinoma. The loss of DNA sequences from the short arm of chromosome 17 (D17S1 locus) was detected in 8 of 9 heterozygous cases of squamous-cell carcinoma and in only 2 of 11 heterozygous cases of adenocarcinomas. Furthermore, in 7 of these 8 squamous-cell carcinomas, loss of heterozygosity from chromosome 17 was accompanied by loss of DNA sequences from chromosome 11. The spectrum of allelic sequences lost from chromosome 11 was, however, similar in every type of carcinoma studied, and the data show two regions commonly deleted from chromosome 11 (11pter-p15.5 and 11p13-q13) that may have a role in the pathogenesis of all these types of non-small-cell bronchogenic carcinoma. Loss of DNA sequences from chromosome 3 was seen in 16 of 31 cases where the constitutive DNA was heterozygous-i.e., informative. These data included only 6 of 16 cases where loss of heterozygosity involved a chromosomal locus previously shown to be lost consistently in small-cell lung cancer (DNF15S2). Loss of heterozygosity at the chromosome 13q locus, D13S3, was seen in 9 of 21 informative cases, and in 2 cases, both adenocarcinomas, duplication of the intact DNA sequences suggested the possibility that mitotic recombination had occurred. Frequent DNA sequence deletions, including those from chromosome 17, in squamous-cell carcinomas may reflect the extensive mutagenic and clastogenic effects of tobacco smoke that may lead to inactivation of putative tumor-suppressor genes.

    Combined thymic carcinoma is a malignant neoplasm of the thymus recently added to the 4th edition of the World Health Organization (WHO) classification of tumors of the lung, pleura, thymus and heart. It involves at least one type of thymic carcinoma and another thymic epithelial tumor. The previously used term "combined thymic epithelial tumor" has been abandoned. Here, we present an unusual case of combined thymic carcinoma of the thymus in a 44-year-old male who had suffered from fever, chest pain, chest tightness and shortness of breath. Magnetic resonance imaging (MRI) detected a mass approximately 6.4 cm × 4.2 cm in the anterior mediastinum, and a nonencapsulated tumor approximately 5.0 cm × 3.5 cm × 2.5 cm with an irregular shape was resected. The morphological features and the immunostaining pattern of the tumor revealed it to be an unusual combined thymic carcinoma consisting of type AB thymoma and squamous cell carcinoma. There were cysts of various sizes, some of which had crack-like structures, in the type AB thymoma area. A gradual transition could be seen between these structures and the squamous cell carcinoma, indicating that the carcinoma portion may have originated from the composition of the thymoma. Combined thymic carcinoma composed of type AB thymoma and squamous cell carcinoma is rare, and the carcinoma portion may have originated from epithelial structures in the type AB thymoma.

    Merkel cell carcinoma of the skin is a tumor generally found in elderly people. This neoplasm involves primarily the dermis; it is locally aggressive often metastatizing to the lymph nodes and, sometimes, diffusely in the body. It must be considered in the diagnostic approach of the cutaneous neoplastic nodules. The clinical, histologic and ultrastructural features of two cases are presented and compared with previously reported examples.

    Tumor-to-tumor metastasis is rare. We report a case of metastatic renal cell carcinoma in meningioma. A 67-year-old woman presented a two-week history of motor dysphagia and decreased short-term memory. She had undergone a left radical nephrectomy for a renal cell carcinoma 7 years ago, and had not received any adjuvant therapy. MRI disclosed a 3.0 x 3.0 x 3.0-cm sized round tentorial-based extraaxial mass with peritumoral edema in the left posterior temporal lobe. During operation, the tumor was found to be an encapsulated mass firmly attached to the tentorium. Histologically, the tumor was a meningotheliomatous meningioma extensively infiltrated by metastatic renal cell carcinoma, accompanying widespread coagulative necrosis. Immunohistochemical staining for cytokeratin revealed strong positivity only in the renal cell carcinoma component. The patient's postoperative course was uneventful. Post-operative radiation therapy was applied to the whole brain. Three months after operation, the patient developed right hemiparesis and dysphagia. Brain MRI at that time did not reveal recurrence or any other causative lesions, although the whole body scan disclosed uptake at the second lumbar vertebra and rib. The patient refused further treatment.

    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.

    ABSTRACT 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. PMID:24492315

    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.

    Hepatocellular carcinoma with neuroendocrine differentiation, where tumor cells stain for both hepatocellular and neuroendocrine markers, is extremely rare. We report a case of a 65-year-old man who presented with a 14-cm rapidly growing mass in the right lobe of his liver with local extension into the gallbladder and portal vein. Serum AFP was 4625ng/mL. Liver biopsy showed a poorly differentiated neoplasm with cells showing nuclear pleomorphism, high nuclear/cytoplasmic ratio, and numerous mitoses. The tumor cells stain for AFP, glutamine synthase, arginase, and glypican-3. The same tumor regions also stain positively for synaptophysin, chromogranin, and CD56. Given this histological pattern, this tumor was ultimately diagnosed as hepatocellular carcinoma with neuroendocrine differentiation. Published by Elsevier Inc.

    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

  9. 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

    Sebaceous carcinoma is a rare aggressive skin cancer derived from the epithelium of sebaceous glands. Sebaceous carcinomas are generally divided as ocular or extraocular locations. Very few cases of extra ocular sebaceous carcinomas have been reported till date. Among them only six cases were reported which were on the chest wall. We are hereby reporting the seventh case of sebaceous carcinoma on the chest wall. The disease exhibits diverse clinical presentations and histologic patterns, often resulting in a delay in an accurate diagnosis as it may mimic many other cutaneous malignancies like Dermatofibrosarcoma protuberance Basal Cell Carcinoma or Squamous Cell Carcinoma. High degree of suspicion is required and sebaceous carcinoma should be considered as one of the differential diagnosis for an ulceroproliferative growth on the skin. PMID:25121026

    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.

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

    Serous tubal intraepithelial carcinoma (STIC) has been implicated in the pathogenesis of pelvic serous carcinoma. We hypothesized that, if this is the case, the frequency of STIC should be substantially lower in endometrial serous carcinomas, in nonserous gynecologic malignancies, and in benign gynecologic neoplasms than in ovarian or peritoneal serous carcinomas. From 2007 to 2009 the fallopian tubes of 342 consecutive gynecologic cases were entirely submitted for histology using the Sectioning and Extensively Examining the FIMbriated end protocol. This study included 300 of these cases (277 TAH-BSO, 23 BSO) after exclusion. The hematoxylin and eosin-stained slides from the fallopian tubes were independently reviewed by 2 gynecologic pathologists who were blinded to all other findings; disagreements were resolved by a third pathologist. Among 46 cases of ovarian malignancies, STIC was identified in 6 (18.8%) of 32 cases of serous carcinoma, but not in any other subtype. Similarly, STIC coexisted in 4 (14.3%) of 28 cases of endometrial serous carcinoma; however, no STIC was identified in any of the 74 cases of nonserous endometrial malignancies. STIC was identified in 2 (28.6%) of 7 cases of peritoneal serous carcinoma. No STIC was identified among 15 nongynecologic malignancies, 90 cases of benign conditions, and 27 cases of other conditions including 4 cases of cervical adenocarcinoma in situ and high-grade cervical intraepithelial lesions, 8 cases of endometrial atypical complex hyperplasias, and 15 cases of ovarian borderline tumors. In conclusion, the fallopian tube may be the origin of some pelvic serous carcinomas. Other possibilities that may explain the origin of pelvic high-grade serous carcinoma are discussed. Given that STIC coexisted with 14% of endometrial serous carcinomas, a more unifying theory may be that gynecologic serous carcinomas and STIC are multifocal lesions.

    A medullary thyroid carcinoma is a malignant tumor derived from the C-cells of the thyroid. Despite their distinct embryological origin, medullary thyroid carcinomas are exceptionally accompanied by a tumor derived from the follicular cells; this is defined as mixed medullary and follicular cell carcinoma. There have been controversies regarding the origin of this rare mixed thyroid carcinoma questioning whether or not a mixed carcinoma originates from a common cancer stem cell. We present a case of mixed medullary and follicular cell carcinoma in which two thyroid carcinomas were found intermingled in the thyroid as well as in the metastatic cervical lymph nodes. We examined the tumor by immunostaining with thyroglobulin, calcitonin, and thyroid transcription factor-1, and also reviewed the literature and discuss the origin of this rare mixed thyroid carcinoma.

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

    To investigate the clinical, pathological character and differential diagnosis of laryngeal verrucous carcinoma. Clinical data of one case with laryngeal verrucous carcinoma in our hospital were retrospectively analyzed. The diagnosis of verrucous carcinoma was difficult and depend on repeated biopsy. Verrucous carcinoma of larynx is a highly differentiated variant of squamous carcinoma that has peculiar clinical and morphological features. The basement membrane is not invaded. It is prone to distant metastasis, than to local recurrence. The case underwent the partial laryngectomy, and was followed up for more than 4 years with no recurrence. Verrucous carcinoma of the larynx is a special pattern of the well-differentiated squamous cancer. A correct diagnosis requires close cooperation between the laryngologist and the pathologist. The main treatment of verrucous carcinoma is complete surgical excision to reserve larynx function as far as possible and improve the quality of life.

    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.

    Oxyphil parathyroid carcinomas are uncommon neoplasms, and the clinicopathologic features of these tumors are largely unknown. We evaluated the clinicopathologic features of oxyphil parathyroid carcinomas and the expression of cytokeratin 14 (CK14), the high-affinity glucose transporter-4 (Glut-4), as well as the cell cycle proteins p27 and Ki67 and compared these with oxyphil parathyroid adenomas and chief cell parathyroid adenomas and carcinomas. Formalin-fixed, paraffin-embedded archival tissues from primary (n = 6) and recurrent (n = 4) oxyphil carcinomas were analyzed and compared with chief cell parathyroid carcinomas (n = 12), oxyphil parathyroid adenomas (n = 38), and chief cell parathyroid adenomas (n = 17) by immunohistochemistry for CK14, Glut-4, p27, and Ki67 using the avidin-biotin peroxidase system. Patients with primary oxyphil and chief cell carcinoma presented with high levels of serum calcium (n = 15.5 and 13.7 mg/dL, respectively). Approximately half the patients in each group died of disease. The Ki67 labeling index was higher (4.9 vs 1.9) and the p27 index lower (23 vs 66) in primary oxyphil carcinoma compared with primary oxyphil adenomas. CK14 was expressed in most oxyphil adenomas (35 of 38 cases) but not in oxyphil carcinomas (0 of 10 cases). Glut-4 was more commonly expressed in both groups of adenomas compared with carcinomas. These results show that oxyphil parathyroid carcinomas are functional malignancies similar to chief cell carcinomas and are associated with hypercalcemia, recurrence, and death. Expression of CK14 is very different in oxyphil adenomas compared with carcinomas. Although distinction between parathyroid adenomas and carcinomas can only be made by histopathologic and clinical findings, these results suggest that immunostaining for CK14, p27, and Ki67 may provide additional information to help distinguish between difficult cases of parathyroid adenomas and carcinomas. These findings also indicate that the same

    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

    Basaloid squamous cell carcinoma (BSCC) is a rare distinct histologic variant of squamous - cell carcinoma of the head and neck region. BSCC is more aggressive and has a poorer prognosis, although histologically, it is associated with squamous cell carcinoma and squamous atypia. The usual site of occurrence for BSCC is the upper aerodigestive tract, floor of the mouth and base of the tongue. This is a case report of an unusual case of BSCC of retromolar trigone, which is quite rare. PMID:22529579

    Intratumor heterogeneity (ITH) poses an urgent challenge for cancer precision medicine because it can cause drug resistance against cancer target therapy and immunotherapy. The search for trunk mutations that are present in all cancer cells is therefore critical for each patient. In this study, we aimed to evaluate the efficiency of multiregional sequencing for the identification of trunk mutations present in all regions of a tumor as a case study. We applied multiregional whole-exome sequencing (WES) to investigate the genetic heterogeneity and homogeneity of a case of gastric carcinoma. Approximately 83% of common missense mutations present in two samples and approximately 89% of common missense mutations present in three samples were trunk mutations. Notably, trunk mutations appeared to have higher variant allele frequencies (VAFs) than non-trunk mutations. Our results indicate that small-scale multiregional sampling and subsequent screening of low VAF somatic mutations might be a cost-effective strategy for identifying the majority of trunk mutations in gastric carcinoma.

    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.

    Increases in the incidence of basal cell carcinoma (BCC) in women, younger age groups and in aggressive scalp subtypes in younger women have been reported. To describe lesion and patient characteristics in scalp BCC. Retrospective audit of scalp BCCs from 3 pathology laboratories in Adelaide, South Australia, January 2009-December 2013. Scalp BCC was 2.6% of all BCC. Of 2,202 patients with scalp BCC, 62% were male and 78% were >60 years. Histologic subtypes included nodular (55%), mixed (30%), and superficial (8%). The concordance between biopsy and excision was 83% for division into nonaggressive and aggressive subtypes. The incomplete excision rate was 16%. Aggressive subtypes were larger and had perineural invasion (PNI) in 8.5% and incomplete excision in 26%. Basal cell carcinoma on the scalp was less common. Men and the elderly had the majority of cases, with no predilection for women, including aggressive histologic subtypes in younger women. Aggressive subtypes were associated with increased size, incomplete excision, and PNI. A preliminary biopsy assisted division into aggressive and nonaggressive histologic subtypes. Incomplete excision rates were higher and increased in aggressive histologic subtypes and PNI. Mohs surgery or wider margins are suggested in these cases.

METHODS: From July 2008 to June 2014, a total of 142 cases of pathologically diagnosed XGC were reviewed at our hospital, among which 42 were misdiagnosed as gallbladder carcinoma (GBC) based on preoperative radiographs and/or intra-operative findings. The clinical characteristics, preoperative imaging, intra-operative findings, frozen section (FS) analysis and surgical procedure data of these patients were collected and analyzed. RESULTS: The most common clinical syndrome in these 42 patients was chronic cholecystitis, followed by acute cholecystitis. Seven (17%) cases presented with mild jaundice without choledocholithiasis. Thirty-five (83%) cases presented with heterogeneous enhancement within thickened gallbladder walls on imaging, and 29 (69%) cases presented with abnormal enhancement in hepatic parenchyma neighboring the gallbladder, which indicated hepatic infiltration. Intra-operatively, adhesions to adjacent organs were observed in 40 (95.2%) cases, including the duodenum, colon and stomach. Thirty cases underwent FS analysis and the remainder did not. The accuracy rate of FS was 93%, and that of surgeon’s macroscopic diagnosis was 50%. Six cases were misidentified as GBC by surgeon’s macroscopic examination and underwent aggressive surgical treatment. No statistical difference was encountered in the incidence of postoperative complications between total cholecystectomy and subtotal cholecystectomy groups (21% vs 20%, P > 0.05). CONCLUSION: Neither clinical manifestations and laboratory tests nor radiological methods provide a practical and effective standard in the differential diagnosis between XGC and GBC. PMID:26640342

    ABSTRACT Background The aim of the present article is to report a case of ameloblastic carcinoma and use a marker alpha smooth muscle actin as a tool to differentiate cases of ameloblastic carcinoma from that of ameloblastoma. Methods Case study reporting a case of ameloblastic carcinoma (AC) with expression of alpha smooth muscle actin (alpha-SMA) as a marker for emergence of stromal myofibroblasts. The expression of myofibroblasts was also compared with that of ameloblastoma. Results Difference between the two lesions in the pattern of expression of alpha smooth muscle actin was also observed. There was increase in the number of myofibroblasts in the stroma of AC while in ameloblastoma, it was comparatively less. Secondly, few areas of the carcinomatous ameloblastic island also exhibited a mild positivity towards alpha smooth muscle actin. Conclusions Increase in number of stromal myofibroblast may be taken as a predictor for carcinomatous transformation. Further studies with greater sample size can validate the use of alpha-SMA as a marker to differentiate ameloblastic carcinoma from ameloblastoma. PMID:24422027

    The author herein reports a case of squamous cell carcinoma (SCC) arising within verrucous carcinoma (VC) of the hard palate. An 84-year-old woman was admitted to our hospital complaining of oral discomfort. Oral examination revealed a pedunculated verrucous tumor (15 x 15 mm) in the hard palate. A biopsy revealed verrucous tumor. Resection of the lesion with wide margins was performed. Grossly, the palate tumor was pedunculated and verrucous, but a depressed area (8 x 7 mm) was recognized. Microscopically, the verrucous ares showed verrucous proliferation of squamous epithelium with little cellular atypia, and was interpreted as VC without invasion. The depressed lesion was obvious SCC with invasion. There were direct transitions between the VC and SCC. Immunohistochemically, the VC and SCC tumor cells were negative for human papilloma virus antigens. P53 protein was expressed in both VC and SCC, though the expression in SCC was much more strong and broad than that in VC. The Ki-67 antigen was also expressed in the VC and SCC, and Ki-67 labeling index ranged was 12% in VC and 64% in SCC. These findings indicate that SCC may arise within VC.

    The thyroglossal duct cyst is the most common developmental anomaly of the thyroid gland. We present a patient with a papillary thyroid carcinoma diagnosed after surgical resection of a thyroglossal cyst. The 39-year-old patient reported to our hospital due to a swelling of this throat. The results of the ultrasonography were reported as showing multiple nodules in both thyroid lobes, and an ~3-cm diameter image in the submental area, in keeping with lymphadenomegalia. In the fine-needle aspiration cytology (FNAC) evaluation from the nodules in the thyroid, it was observed that the thyrocites with uniform nuclei made up single-layer groups. FNAC from the thyroglossal cyst, a few histiocytes were observed on a ground with a large number of erythrocytes. The patient was subjected to a total thyroidectomy, pyramidal lobe excision, and total excision of the 3-cm diameter soft mass, starting at the tip of the pyramidal lobe. The case was diagnosed as papillary thyroid carcinoma in thyroglossal duct cyst with histopathological and immunohistochemical findings. If the thyroglossal channel cyst had been diagnosed preoperatively, total thyroidectomy and a Sistrunk operation would have been performed. For this reason, repeated FNAC, particularly, if performed under ultrasound guidance, may improve the diagnostic value of FNAC. Thus, in such patients, throat ultrasonography must be carried out in expert hands, thin-needle aspiration biopsy, computerized tomography, and thyroid scintigraphy must be done if necessary, and the necessary treatment protocols carried out after a definite diagnosis.

    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 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.

    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.

    Anal cancer is a rare tumor that accounts for 2% of all colorectal neoplasms. The brain is a rarely affected organ. The aim of the present study was to the review the only four cases of anal cancer brain metastases previously published in the literature. In addition, the current study presents the case of a 69-year-old male diagnosed with basaloid undifferentiated carcinoma of the anal canal (stage IV with liver, lung and bone metastasis). Despite the patient’s good response to chemotherapy and the achievement of a partial response that was maintained for 14 months, brain metastases developed. Although radiotherapy was administered, the patient succumbed to the condition 12 weeks after the diagnosis of brain metastasis. PMID:24944707

    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

    To explore the clinical features, management, and prognosis of metastatic basal cell carcinoma originating in the orbitofacial region. Ten cases of orbitofacial metastatic basal cell carcinoma were identified by searching databases at 2 institutions from 1995 to 2015. A retrospective chart review was performed. Main outcome measures included patient demographics, lesion size, location of metastases, histologic subtype, recurrence rate, time between primary tumor diagnosis and metastasis, perineural invasion, treatment modalities, and survival from time of metastasis. The median tumor size at largest dimension was 3.3 cm (range, 1.9-11.5 cm), and 6 of 10 patients had at least 1 local recurrence before metastasis (range, 0-2 recurrences). The most common sites of metastasis included the ipsilateral parotid gland (n = 6) and cervical lymph nodes (n = 5). Histologic subtypes included infiltrative (n = 5), basosquamous (n = 2), nodular (n = 1), and mixed (n = 1). The median time from primary tumor diagnosis to metastasis was 7.5 years (range, 0-13). The median survival time from diagnosis of metastasis to last documented encounter or death was 5.3 years (range, 7 months-22.8 years). Treatment regimens included surgical excision, radiotherapy, and hedgehog inhibitors. Based on our findings, the following features may be markers of high risk orbitofacial basal cell carcinoma: 1) increasing tumor size, 2) local recurrence of the primary tumor, 3) aggressive histologic subtype, and 4) perineural invasion. Screening should include close observation of the primary site and tissues in the distribution of regional lymphatics, particularly the parotid gland and cervical lymph nodes.

    Mucinous carcinoma is a less common histologic variant of breast cancer. Cases of mucinous carcinomas in male breast are extremely rare. 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.

    Thyroid hemiagenesis is a rare congenital anomaly in which 1 thyroid lobe fails to develop. Co-occurrence of hemiagenesis and thyroid carcinoma is extremely rare. Here, we report 2 cases of thyroid hemiagenesis with carcinoma. The first patient was referred with a left thyroid mass and absent right lobe. The frozen section examination revealed medullary thyroid carcinoma (MTC); therefore, a left thyroid lobectomy plus neck dissection was performed. Another patient was referred with a right thyroid mass and absent left lobe. Fine-needle aspiration biopsy was suspicious for papillary carcinoma. The patient underwent right thyroid lobectomy plus neck dissection. The operative findings confirmed hemiagenesis of the right lobe and MTC in the left lobe for the first case, and hemiagenesis of the left lobe and papillary carcinoma in the right lobe for the second case. Our case represents the first reported case of association between thyroid hemiagenesis and MTC. © 2014 Wiley Periodicals, Inc.

    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.

    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

    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.

    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

    We report the case of a 32-year old woman with an anterior cervical cystic mass originating in the thyroglossal duct. At surgical exploration, the mass was reacted, including the thyroglossal duct and the mid-portion of the hyoid bone (Sistrunk's procedure). The histopathologic study demonstrated a papillary carcinoma. Fine needle aspiration biopsies of both thyroid lobes were performed postoperatively without any histopathologic abnormalities. The patient was discharged without performing any other surgical procedure and without complications. Treatment with I131 and thyroid hormones was initiated, and at 11 months of follow-up, the patient is asymptomatic without any evidence of local or distant recurrence. The clinical and histopathological features are discussed, as well as the therapeutic options for this type of uncommon malignant neoplasm.

    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.

    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

    2013-01-01

    A 5-½-month-old female Holstein-Friesian calf was presented with a history of recurring ruminal tympany and poor development. The absence of lung sounds on the right hemithorax suggested a right-sided intrathoracic pathology. Radiography and computed tomography revealed a large thin-walled cavernous lesion with a gas-fluid interface which almost completely filled the right thoracic cavity. Fluid aspirated from the lesion was clear, yellowish and odorless. These findings led to the diagnosis of a bronchogenic cyst. Thoracotomy was performed under general anesthesia. The cyst strongly adhered to the adjacent lung tissue. After removal of the free wall, the adjacent lung tissue was sealed using surgical stapling instruments, and the non-removable part of the wall was curetted and rinsed. The intensive postoperative management included antibiotic therapy, oxygen supplementation and regional lidocaine infusion. Anti-inflammatory drugs were administered for further pain control. The calf recovered well and was released from the clinic on postoperative day 11. Intra- or extrathoracic bronchogenic cysts result from abnormal budding during the embryonic development of the tracheobronchial system. Successful treatment of this calf despite the size of the lesion and the invasive character of the surgical intervention indicates that resection of bronchogenic cysts in cattle may be an option for valuable animals.

    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.

    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.

    Human papillomavirus-associated oropharyngeal squamous cell carcinoma is now recognised as a subtype of head and neck cancer with distinct clinical, molecular and histological characteristics. The majority of these carcinomas are of non-keratinising squamous type but there is a growing number of histomorphologic variants of this disease. Here we describe the clinical, histomorphologic and immunophenotypic features of two cases of human papillomavirus-associated oropharyngeal squamous cell carcinoma demonstrating a clearly delineated biphasic differentiated and undifferentiated phenotype.

    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

    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.

    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).

    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.

    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

    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

    Although the simultaneous presentation of endometrial and ovarian carcinomas of the endometrioid type is well described, little is known about a similar phenomenon involving the endometrium and fallopian tube (FT). We present the clinicopathologic features of 13 such cases seen in the Department of Pathology at The University of Texas M.D. Anderson Cancer Center over an 8 year period (1995 to 2002). FT tumors that could have represented luminal extension of the endometrial carcinoma or that represented an unequivocal metastasis to the FT were excluded. The patients' ages ranged from 34 to 77 years (median 54). The most common symptom was abnormal uterine/vaginal bleeding (11) and all of the patients were considered overweight or obese (mean body mass index was 41). The size of the endometrial carcinomas ranged from 0.3 to 8 cm. According to the FIGO grading of the endometrial endometrioid carcinomas, the cases were distributed as follows: Grade 1 (3) and Grade 2 (10). In 2 cases, there were also small areas of other histologic types, papillary serous carcinoma (1 case), and papillary endometrial carcinoma of intermediate grade (another case). The size of the fallopian tube carcinomas ranged from 0.2 to 17.5 cm. Seven of these tumors were located in the distal/fimbriated end of the FT. There was bilateral involvement in 2 cases. Three of the FT tumors were in situ. The grades of the fallopian tube carcinomas were as follows: Grade 1 (2), Grade 2 (6), and Grade 3 (2). In situ components were seen in all cases. One fallopian tube carcinoma was mixed with serous carcinoma. In 4 cases, there was also an endometrioid carcinoma involving the ovary, all of them with an intact ovarian capsule. Patients were treated as follows: total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH/BSO) (4), TAH/BSO/chemotherapy (chemo) (4), TAH/BSO/radiation (3), and TAH/BSO/chemo/radiation (2). Follow-up ranging from 6 to 54 months was available in 10 patients: 1 patient

    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.

    Plasmacytoid urothelial carcinoma is an uncommon and aggressive variant of urothelial carcinoma associated with late presentation and poor prognosis. We discuss here the first reported case from India of a 54-year-old male who presented with hematuria. Cystoscopy showed edematous and ulcerated mucosa throughout the bladder. A transurethral biopsy revealed urothelial carcinoma with plasmacytoid appearance. He underwent a radial cystectomy which on histopathology showed plasmacytoid urothelial carcinoma of the bladder of high stage with involvement up to bladder serosa and adventitial walls of the ureter. The diagnostic dilemmas of this unusual variant of urothelial malignancy and its clinical impact are discussed. PMID:21716882

    A lymphoepithelioma-like carcinoma (LLC), characterized by a carcinoma with stromal heavy lymphocyte infiltration, is one of the histological patterns observed in patients with Epstein-Barr virus (EBV)-associated gastric carcinoma. Although this entity is hard to be recognized in the biopsy specimens, pathologists and clinicians should acknowledge this subset of gastric cancer because it generally has a better prognosis than other forms of EBV-associated gastric carcinomas and conventional gastric carcinomas. This might be due to the fact that the patient's inflammatory response may prevent the spread of tumor through the gastric wall and to the lymph nodes or remote organs.We report a case of EBV-positive, microsatellite stable LLC as a rare morphologic variant of gastric carcinoma.

    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. © The Author(s) 2016.

    Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy. Sarcomatoid adrenal carcinoma is even more aggressive type of ACC. 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

    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.

    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.

    A 21-year-old girl arrived at our hospital with a short history of hirsutism, facial pletora, amenorrhea, progressive weight gain and hypertension. The clinically suspected Cushing syndrome was then confirmed through chemical pathology. In fact, the results from hemato-chemical exams were: 45.5 Ig/dl cortisol, a DHEA sulphate >8000 ng/ml, 7.2 pg/ml ACTH, 17OH-Progesterone 10.66 ng/ml, Delta-4 Androstenedione 5.2 ng/ml, UFC (Urine Free Cortisol) >1000 mg/24h, FSH 0.8 mUI/ml, LH < 0.1 mUI/ml, Prolactin 13, 17, estradiol 96 pg/ml, and a bonded hypokalaemia, K+ 2,4 mEq/L. The echogram of the complete abdomen reveals, near the superior pole of the left kidney, the presence of a solid mass, not independent from the pole itself about 9.5 centimetres long, diagnosis confirmed to the TC abdomen and pelvis too, with or without mdc. This removed mass resulted, from the histological exam, in an adrenal carcinoma with a general and trabecular structure. Primal adrenal tumours are responsible for about 10% of Cushing syndrome cases. They present an annual incidence of 0.5 - 2.0 cases per million of inhabitants. The prognosis of adrenal ca remains low, with 5 year survival rate for 38% of diagnosed patients.

    We present the case of a 51 year-old-white male with a giant right renal arteriovenous fistula secondary to a carcinoma. Neither the aorta nor the kidneys were visualized after the injection of 60 mL of contrast media into the abdominal aorta. Moreover, the right kidney could not be visualized after 30 mL of contrast media were injected selectively into the right renal artery. This was due to a great arteriovenous shunt through the right kidney. The right renal angiogram was obtained through digital imaging, after injecting contrast media into the right renal artery, previously occluded by a balloon-catheter. The image of an hypervascularized nephroma was obtained, depicting an important arteriovenous shunt of the contrast material toward the inferior vena cava from a fistula located in the right inferior renal pole. The occlusion of the right renal artery was partially achieved by injecting 40 mL of boiling contrast media, followed by small fragments of Gelfoam suspended in the contrast substance. The balloon-catheter remained inflated in the right renal artery until a nephrectomy was performed. As far as we know, a case in which the aorta and renal circulation are unable to be seen by means of conventional angiography, because of the presence of a renal arteriovenous shunt to the fistula, has not been described.

    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

    Basaloid squamous cell carcinoma is a rare aggressive malignancy that is a distinct variant of squamous cell carcinoma. This report presents 2 cases of basaloid squamous cell carcinoma in the gingiva. Case 1 is a 55-year-old Japanese man who presented with a painful, red, and irregular mass on the left mandibular gingiva. Case 2 is a 65-year-old Japanese man who presented with a painless mass on the right mandibular gingiva. Both tumors were diagnosed histopathologically as basaloid squamous cell carcinoma. In case 1, the patient underwent wide resection of the gingival tumor with a partial mandibulectomy and ipsilateral functional neck dissection. The mandible was reconstructed with a titanium plate and forearm flap. In case 2, the patient underwent wide resection of the gingival tumor after local irradiation (60 Gy). At the time of writing, both patients remained in good health and free of disease.

    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

    Thymic carcinoma (primary carcinoma of the thymic epithelium; type C thymoma) is a rare malignancy. It usually presents in middle-aged to elderly patients and can exhibit a wide variety of morphologic appearances. Thymic basaloid carcinoma (thymic BC) is a particularly rare subtype, with less than 20 cases published in the English literature, mostly in the form of individual case reports. In this study, we present the clinicopathologic and immunohistochemical features of 12 new cases of thymic BC. There were 10 (83%) men and 2 (17%) women. Ages at the time of initial diagnosis ranged from 34 to 77 years (mean 55 y). The 2 most common manners of presentation were dyspnea on exertion (3 patients) and as an incidental finding on radiographic imaging (2 patients). Tumors ranged in size from 4.4 to 17 cm (mean 10.1 cm). One of 12 cases (8.3%) was associated with a multilocular thymic cyst. Immunohistochemistry was performed in 8 cases. Pan-cytokeratin was positive in all cases. CD117 (c-kit) was positive in 6 of 8 cases (75%), p63 was positive in 7 of 8 cases (88%), p53 was positive in 7 of 8 cases (88%), ranging from <10% to 90%, CD5 was focally positive in 3 of 8 cases (38%), collagen type IV was positive in 4 of 8 cases (50%), and proliferative index, as estimated by Ki67, ranged from <1% to approximately 15%. In 1 of 2 cases with sarcomatoid differentiation, Ki67 was greater than 80% in the sarcomatoid area. Cases were negative for thyroid transcription factor-1 (0 of 8), S-100 (0 of 7), and synaptophysin (0 of 7). Long-term data was available in 8 patients with an average follow-up of 30 months. Five patients died of their disease at an average of 34 months from the time of diagnosis. Of the remaining 3 patients, 1 had a stable recurrence and died at 4 years from unrelated causes, and 2 were alive without the evidence of disease at 12 and 7 months, respectively. Thymic BC, although previously regarded as a low-grade neoplasm, has shown that it is capable of

  14. Two different scenarios of squamous cell carcinoma within advanced Basal cell carcinomas: cases illustrating the importance of serial biopsy during vismodegib usage.

    Vismodegib is a Hedgehog signaling pathway inhibitor recently approved by the US Food and Drug Administration for advanced basal cell carcinoma. We present 2 cases of clinically significant squamous cell carcinoma within the tumor bed of locally advanced basal cell carcinoma found during vismodegib treatment. The first case is that of a patient with locally advanced basal cell carcinoma responsive to vismodegib but with an enlarging papule within the tumor bed. On biopsy, this papule was an invasive acantholytic squamous cell carcinoma. The second case is that of a patient with Gorlin syndrome with a locally advanced basal cell carcinoma that was stable while the patient was receiving therapy with vismodegib for 2.5 years but subsequently increased in size. Biopsy specimens from this tumor showed invasive squamous cell carcinoma, spindle cell subtype. In both cases, the squamous cell carcinomas were surgically resected. These cases highlight the importance of repeated biopsy in locally advanced basal cell carcinomas in 2 clinical situations: (1) when an area within the tumor responds differentially to vismodegib, and (2) when a tumor stops being suppressed by vismodegib. Timely diagnosis of non-basal cell histologic characteristics is critical to institution of effective therapy.

    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.

    This report describes a case of serous ovarian carcinoma with occult serous tubal intraepithelial carcinoma (STIC), which presented as atypical glandular cells favor neoplasia (AGC-FN) with Pap cytology and dermatomyositis. A 48-year-old woman presented with symptoms of dermatomyositis. An AGC-FN result from a Pap smear, with an absence of a cervical or endometrial lesion was noted. After cancer surveillance, ovarian high grade serous carcinoma associated with serous tubal intraepithelial carcinoma was diagnosed. Two weeks following surgical excision of the carcinoma, dramatic remission of the dermatomyositis symptoms was evident. The patient had serous carcinoma of the ovary with tubal STIC, which presented as dermatomyositis. The AGC-FN identified from a Pap smear hinted at a diagnosis of ovarian carcinoma. These presentations point to an occult malignancy in the genital tract and demand careful diagnostic workup. Copyright © 2015. Published by Elsevier B.V.

    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.

    Primary malignant tumors of the renal pelvis are relatively rare. Urothelial carcinoma of renal pelvis accounts for 7% of all renal neoplasms, with Squamous Cell Carcinoma (SCC) forming a very small percentage of these cases. Urothelial and SCC of renal pelvis is still a rarer entity. This malignancy of the renal pelvis lacks the characteristic presentation of common renal cell carcinoma and usually presents at an advanced disease stage. We report a case of urothelial and SCC of renal pelvis in a 61-year-old male who presented with non-specific clinical complaints like dysuria and right flank pain. PMID:27790450

    Primary neuroendocrine carcinomas of the genitourinary tract are rare and aggressive tumors carrying a bad prognosis. 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.

We present the case of a 55-year-old woman with a palpable mass in the right breast and clinical signs of locally advanced breast cancer (LABC). The diagnosis of GRCC carcinoma was based on certain histopathological characteristics of the tumor and immunohistochemical analysis. To our knowledge, this is the first case of GRCC LABC with intratumoral calcifications. There is no evidence of recurrence or metastatic disease after 14 months’ follow-up. PMID:22087097

    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.

    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.

    Solid-pseudopapillary tumour (SPT) is a rare exocrine tumour of the pancreas and is considered to have low malignant potential. Few morphological criteria are used to predict malignant behaviour such as equivocal perineural invasion, angioinvasion and invasion to surrounding tissue, and should be designated as solid-pseudopapillary carcinoma (SPC). We report a case of SPC. Clinical and radiological findings are typical for SPT with no metastatic disease. There is no tumour recurrence after 4 months postresection. Clinical history and radiological findings were retrieved from the patient's record sheet and Viarad system. H&E staining and few immunoproxidase staining were reviewed by several pathologists. The histological findings are typical for SPT, with additional perineural invasion. There is no angioinvasion or capsular invasion identified. This is our first experience in diagnosing and managing SPC. We look forward to seeing the patient's disease status during her next routine follow-up. We expect good disease-free survival and very low risk of tumour recurrence, in view of only one risk factor (perineural invasion) and uninvolved surgical margins by the tumour.

    Matrix-producing breast cancer (MPC) is a subtype of metaplastic carcinoma of the breast. It is a very rare tumor, which constitutes less than 1% of all malignant mammary tumors. The origin of this tumor is still unclear: there are molecular studies that suggest an origin from myoepithelial cells, whereas other studies underline the neoplastic transformation of a multipotent stem cell. Even the differential diagnosis of MPC and other breast neoplasms (phyllodes tumors and real sarcomas of the breast) is not always easy. In the literature, a certain chemoresistance has been demonstrated, and a standard treatment of this tumor does not exist at this time. We report the case of a 44-year-old, premenopausal, female patient with a 6-cm breast lump. Neither imaging nor fine needle aspiration biopsy was crucial in achieving a diagnosis. The patient underwent a simple mastectomy. In consideration of the negative lymph node status, the patient was not subjected to radiotherapy or adjuvant chemotherapy. Moreover, since the receptor status was negative, hormone therapy was not necessary. The patient has been disease free for 4 years now.

    Carcinoma gall bladder accounts for 98% of all the gall bladder malignancies and is the sixth most common malignancy of the gastrointestinal tract worldwide. Incidental gall bladder carcinoma (IGBC) is an incidental finding of carcinoma diagnosed during a laparoscopic cholecystectomy or on histopathological examination of gall bladder specimen removed for benign gall bladder diseases. The incidence of IGBC is around 0.19 - 3.3% in the literature. The aim of the present study was to report our experience with gall bladder cancers which were incidentally diagnosed during histopathological examination of cholecystectomy specimens done for benign gall bladder disease and follow up of the cases. This study includes 270 cholecystectomy specimens which were removed, during June 2010 to July 2011 in a tertiary care hospital. The clinicopathological findings of cases with incidentally detected gall bladder cancers were recorded; age, sex, presenting symptoms, presence of gall stones and histologic grade and staging of tumours were included. Exclusion criteria included preoperative suspicion of malignancy before cholecystectomy. American joint committee on cancer (AJCC) staging system was used for staging incidental gall bladder carcinoma. In our study laparoscopy or open cholecystectomy was attempted in 270 cases during the one year period. Incidental gall bladder carcinomas were diagnosed in 7 cases (2.59%), with mean age of 50 years. Pain, vomiting, and dysphagia were the presenting complaints. USG revealed thickened gall bladder in 6 cases, and polyp in one case. Gall stones were seen in 6 cases. Histopathology showed moderately differentiated adenocarcinoma in all the cases. AJCC staging of gall bladder carcinoma revealed 6 cases in pT2 stage and pT1 a stage in one case. On follow up at 22 months, 6 cases were alive while one expired due to tumour metastasis. Prognosis of incidental gall bladder carcinoma is better, if diagnosed in early stages.

    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.

    Verrucous carcinoma is a rare variant of squamous cell carcinoma. It is well differentiated and rarely metastases but can sometimes be very aggressive locally in depth. The paper presents three cases of cutaneous verrucous carcinoma with different localizations. The first patient shows a lesion in the sacrogluteal region, the second one presented a tumor localized on the auricle (external ear), and the third patient showed a tumor on the sole of the foot. All patients underwent tumor excision and the histopathological diagnosis was verrucous carcinoma. In the first two cases, the surgery was completely curative by excision of the tumors. In the last case, the patient had relapsed and due to the aggressive nature of the tumor, which infiltrated the deeper plans, the tumor had reached the bone. None of the patients showed any metastases.

    Gastric lymphoepithelioma-like carcinoma is a rare carcinoma among gastric malignant tumor but has a good prognosis. The carcinoma has histologic feature characterized by small nest of cancer cells mixed with lymphoid stroma. We report a case with lymphoepithelioma-like carcinoma of stomach initially presenting as panperitonitis because of spontaneous tumor perforation. A 56-year-old man visited our emergency room because of epigastric pain. A preoperative abdominal CT scan showed a massive pneumoperitoneum in the upper abdomen, and the presence of gastric cancer in the lesser curvature of the stomach. An emergent laparotomy was performed followed by radical subtotal gastrectomy. Pathologic examination revealed that the tumor was a lymphoepithelioma-like gastric carcinoma.

    Neuroendocrine tumors of the colon and rectum are relatively rare compared to sporadic colorectal carcinoma. There are few reports of neuroendocrine tumors of the colon and rectum in patients with ulcerative colitis. A patient with sigmoid colon carcinoma with focal neuroendocrine features is presented. A 32-year-old man, who had been followed for ulcerative colitis for 14 years, was found to have carcinoma of the sigmoid colon on routine annual colonoscopy, and he underwent laparoscopic total colectomy. Pathologic examination showed sigmoid colon adenocarcinoma with focal neuroendocrine features. Most colorectal carcinomas associated with inflammatory bowel disease are histologically similar to the sporadic type, and tumors with neuroendocrine features are very unusual. Very rare case of sigmoid colon carcinoma with neuroendocrine features arising in a patient with UC was described. Copyright © 2016 The Author(s). Published by Elsevier Ltd.. All rights reserved.

    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.

    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 mucinous carcinoma of the thyroid gland is a rare disease; only 6 cases of primary mucinous carcinoma of the thyroid have been previously reported. Primary mucinous carcinoma of the thyroid gland with incomplete tumor resection tends to be associated with a poor prognosis, resulting in death within a few months. An early and appropriate diagnosis may contribute to improvement in patient prognosis; however, it is extremely difficult to diagnose primary mucinous carcinoma of the thyroid. We present the seventh reported case of primary mucinous carcinoma in the thyroid gland; moreover, rhabdoid cells were detected, which, to our knowledge, is a novel finding. An 81-year-old Japanese woman was initially diagnosed with a poorly differentiated thyroid carcinoma, and she underwent a hemithyroidectomy. Pathological examination revealed the presence of abundant mucus and agglomeration of large atypical cells. Rhabdoid cells were also seen scattered among the tumor cells. Immunostaining was performed for various markers, and on the basis of these results, we diagnosed the lesion as primary mucinous carcinoma with rhabdoid cells in the thyroid gland. Ten months after surgery, recurrence was noted in the paratracheal lymph nodes; therefore, total resection of the residual thyroid gland and paratracheal lymphadenectomy with thyroid-stimulating hormone suppression were performed. The patient is currently alive and disease-free. The current case is of interest not only because of the rare histological findings, but also because the patient achieved long-term survival following diagnosis of a mucinous carcinoma. We believe this report will be helpful for diagnosing future cases of mucinous carcinoma of the thyroid.

    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

    The purpose of this clinical study was to identify a clinical and histopathological relationship between verrucous hyperplasia, verrucous keratosis, and verrucous carcinoma. We evaluated 12 patients who had developed oral verrucous carcinoma in the past 10 years in a follow-up study. In this study, the diagnostic criteria included clinical and histopathological features of the lesions. Each lesion was examined by a single oral pathologist. All the patients were diagnosed with verrucous carcinoma following excisional biopsy. One patient was diagnosed with verrucous hyperplasia and another with verrucous keratosis in their initial histological findings. Mandibular, posterior alveolar crest, and retromolar trigone were the most affected sites (41.6%), followed by the buccal mucosa (16.6%), the palate (16.6%), the floor of the mouth (16.6%), and the lip (8.3%). No patients had evidence of recurrence after treatment. Verrucous hyperplasia, verrucous keratosis, and verrucous carcinoma may not be distinguished clinically or may coexist, resulting in diagnostic difficulties. It should be kept in mind that verrucous hyperplasia may also develop from leukoplakic lesions, and it may transform into verrucous carcinoma or squamous-cell carcinoma, acting as a potential precancerous lesion.

    Parathyroid gland carcinoma is a rare malignancy. The tumor is mostly functioning, causing severe hyperparathyroidism, with high serum calcium level and severe bone disease. Non-functioning parathyroid carcinomas are extremely rare. We report on a 60-year-old male patient admitted to ENT Department due to a large neck tumor mass compressing the thyroid and trachea. Preoperatively, thyroid hormone, parathyroid hormone (PTH) and calcium serum levels were normal. The following immunohistochemical markers (DAKO, Denmark) were used: bcl-2; CD-10; Chromogranin-A; Cyclin-D1; EMA; Ki-67; Mdm-2; p-53; PGP-9,5; RCC; Synaptophysin; Thyroglobulin; and TTF-1. Immunohistochemical analysis indicated the diagnosis of a primary parathyroid gland carcinoma. Tumor cells showed diffusely positive immunohistochemical staining with chromogranin-A and PGP-9,5, positive staining of variable intensity with synaptophysin, and weakly positive reaction with EMA. Also, the cytoplasm of tumor cells was diffusely positively stained with bcl-2, while the nuclei showed positive reaction with p-53 oncogene and TTF-1. The remaining markers (CD-10, cyclin-D1, Ki-67, Mdm-2, RCC and thyroglobulin) were negative. Four years after the surgery, the patient died from renal carcinoma pulmonary metastases and liver cirrhosis complications. In conclusion, non-functioning parathyroid gland carcinoma is a very rare disease. Detailed immunohistochemical analysis is needed to distinguish it from other thyroid and parathyroid neoplasms and metastatic carcinoma. Surgical treatment is presently the best mode of therapy.

  4. Merkel cell carcinoma – description of five cases

    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

  5. Bladder carcinoma with shadow cell differentiation: a case report with immunohistochemical analyses.

    2012-01-01

    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.

    Esophageal verrucous carcinoma is a rare variant of esophageal squamous cell carcinoma. In most cases, verrucous carcinoma presents as an exophytic, slow-growing mass with an extensive superficial growth pattern. Symptoms often include an insidious onset of dysphagia resulting in weight loss. In a patient presenting with super early-stage verrucous carcinoma, we were able to eliminate the aberration using endoscopic submucosal dissection. An asymptomatic 68-year-old Asian man was found to have an abnormality in his esophagus. The abnormality was discovered, by chance, in a barium study for a health checkup. Esophagogastroduodenoscopy revealed a 1-centimeter polypoid lesion covered with squamous epithelium. Biopsies showed squamous high-grade intraepithelial neoplasia. An endoscopic submucosal dissection was performed and the histopathological findings showed a well-differentiated squamous cell carcinoma with hyperkeratosis with a church spire configuration. These features are consistent with the growth pattern of verrucous carcinoma. Verrucous carcinoma can manifest as a small mass with nonclinical symptoms and endoscopic submucosal dissection is useful as a curative treatment. We must consider that verrucous carcinoma can manifest as appearance of a polyp that is not papillary or warty-like with and without extensive superficial growth appearance.

    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.

    In 2015, thyroid carcinoma affected approximately 63,000 people in the USA, yet it remains one of the most treatable cancers. It is mainly classified into medullary and non-medullary types. Conventionally, medullary carcinoma was associated with heritability but increasing reports have now begun to associate non-medullary thyroid carcinoma with a genetic predisposition as well. It is important to identify a possible familial association in patients diagnosed with non-medullary thyroid carcinoma because these cancers behave more destructively than would otherwise be expected. Therefore, it is important to aggressively manage such patients and screening of close relatives might be justified. Our case series presents a diagnosis of familial, non-syndromic, non-medullary carcinoma of the thyroid gland in three brothers diagnosed over a span of 6 years. We report the history, signs and symptoms, laboratory results, imaging, and histopathology of the thyroid gland of three Pakistani brothers of 58 years, 55 years, and 52 years from Sindh with non-medullary thyroid carcinoma. Only Patients 1 and 3 had active complaints of swelling and pruritus, respectively, whereas Patient 2 was asymptomatic. Patients 2 and 3 had advanced disease at presentation with lymph node metastasis. All patients underwent a total thyroidectomy with Patients 2 and 3 requiring a neck dissection as well. No previous exposure to radiation was present in any of the patients. Their mother had died from adrenal carcinoma but also had a swelling in the front of her neck which was never investigated. All patients remained stable at follow-up. Non-medullary thyroid carcinoma is classically considered a sporadic condition. Our case report emphasizes a high index of suspicion, a detailed family history, and screening of first degree relatives when evaluating patients with non-medullary thyroid carcinoma to rule out familial cases which might behave more aggressively.

    Background Salivary duct carcinoma with rhabdoid features is extremely rare. Methods We report 2 cases of salivary duct carcinoma with rhabdoid features treated at our institution. Results Case 1 was a 44-year-old Japanese man who had swelling in the left parotid region. This tumor consisted of residual pleomorphic adenoma and widely invasive carcinoma, which showed a diffuse growth pattern by atypical rhabdoid cells. Case 2 was a 66-year-old Japanese man who had swelling of the right cervical region. This submandibular tumor was also composed of both residual pleomorphic adenoma region and invasive adenocarcinoma components, whereas some metastatic lesions were purely composed of rhabdoid cells. Such cells were strongly and diffusely positive for cytokeratins (CKs), gross cystic disease fluid protein-15 (GCDFP), and androgen receptor (AR). Case 1 was also positive for Her-2 and p53. Conclusion Both patients were diagnosed with carcinoma ex pleomorphic adenoma and their carcinomatous components were composed of salivary duct carcinoma with rhabdoid features, which is a highly aggressive tumor, similar to salivary duct carcinoma. © 2013 The Authors.

    Corrective eyeglasses are frequently worn by adults, particularly at older ages. Their lenses and frames provide ultraviolet protection. Medial canthal basal cell carcinomas are infrequent (3-8%), and their relation with the use of corrective glasses was not yet investigated. To assess the prevalence of corrective eyeglasses use in individuals with medial canthal basal cell carcinoma. Case-control study using two controls matched by age, gender, and ethnicity for each case. Cases were patients with medial canthal basal cell carcinoma, and controls were patients with basal cell carcinoma elsewhere on the face. The prevalence of major risk variables was estimated and adjusted by conditional multiple logistic regression. Fifty cases and 100 controls were assessed. The mean patient age was 69.7 years, and 54% of the subjects were females. No difference regarding the eyeglasses use or use duration was found between groups. However, when visual defects were separately evaluated, eyeglasses for myopia correction were independently associated with lower risk of medial canthal basal cell carcinoma development (OR=0.26; P=0.03), what can be related to long term local photoprotection. The use of eyeglasses for myopia correction is associated with lower prevalence of medial cantal basal cell carcinoma. Risk-reducing mechanisms should be elucidated. © 2011 The Authors.

    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.

    Endometrial cancer generally carries a good prognosis. Endometrial carcinoma more frequently metastasizes to the pelvic and para-aortic nodes. Visceral metastases usually occur in the vagina and ovaries. Distant metastases involve lungs and occur as a terminal event. This case report describes vulvalar metastasis of endometrial cancer to the clitoris. Metastatic tumors of the vulva are rare. Moreover, in the presence of metastatic endometrial carcinoma to the vulva, it is necessary to verify if other visceral metastases are present. Endometrial cancer can extend through direct dermatogens and lymphatic spread. We report a clitoral metastasis of an endometrial carcinoma and discuss whether the possible mechanism is vascular spreading or direct seeding.

    Primary intra-osseous mucoepidermoid carcinoma arising from jaw is an extremely rare condition accounting to less than 2% of all mucoepidermoid carcinomas. In the jaw, it occurs more commonly in mandible than maxilla. They are low-grade cancers and affect jaw as uni- or multi-locular radiographic lesions. Here we discuss a rare case of giant cystic primary intra-cystic mucoepidermoid carcinoma of the mandible which was excised in toto. Here we discuss the clinical features, radiological and histological characteristics of this rare lesion, and review the literature.

    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.

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.

    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

    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.

    Metastasis to the primary thyroid carcinoma is extremely rare. We report here a case of colonic adenocarcinoma metastasis to medullary thyroid carcinoma in a 53-yr old man with a history of colon cancer. He showed a nodular lesion, suggesting malignancy in the thyroid gland, in a follow-up examination after colon cancer surgery. Fine needle aspiration biopsy (FNAB) of the thyroid gland showed tumor cell clusters, which was suspected to be medullary thyroid carcinoma (MTC). The patient underwent a total thyroidectomy. Using several specific immunohistochemical stains, the patient was diagnosed with colonic adenocarcinoma metastasis to MTC. To the best of our knowledge, the present patient is the first case of colonic adenocarcinoma metastasizing to MTC. Although tumor-tumor metastasis to primary thyroid carcinoma is very rare, we still should consider metastasis to the thyroid gland, when a patient with a history of other malignancy presents with a new thyroid finding.

    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

    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

    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.

    Biliary (hepatic and extrahepatic) intraductal papillary mucinous neoplasms and intraductal oncocytic papillary neoplasms/carcinoma are rare neoplasms. Classification of biliary intraductal papillary tumors can be confusing and reports in radiology literature are extremely limited. We describe the first reported case of biliary intraductal oncocytic papillary neoplasms/carcinoma in the liver in Australia. The intraductal nature of such neoplasms can be identified on magnetic resonance imaging and magnetic resonance cholangiopancreatography.

    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

    Ameloblastic carcinoma is a rare lesion of odontogenic origin. It is defined as a malignant epithelial odontogenic tumor that histologically has retained the features of ameloblastic differentiation and also exhibits cytologic features of malignancy, like atypia and mitotic activity. Although this lesion represents a separate entity, differentiating it from ameloblastoma has been often challenging to pathologists. In this case study reporting a case of ameloblastic carcinoma, we have attempted to verify the previous findings on the use of Argyrophilic nucleolar organizing regions (AgNORs) and immunohistochemical staining for the alpha-smooth muscle actin (alpha-SMA) in differentiating ameloblastic carcinoma from ameloblastoma. It was observed that AgNORs was found to be almost twice in ameloblastic carcinoma as it was in ameloblastoma. A difference between the two lesions in the pattern of expression of alpha-SMA was also observed, with alpha-SMA being expressed in the odontogenic epithelium and the stroma of ameloblastic carcinoma whereas, in the case of ameloblastoma, it was found only in the stromal part. These findings suggest that AgNORs and alpha-SMA expression may be used as adjuncts to the routine histopathologic examination to differentiate ameloblastic carcinoma and ameloblastoma.

    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.

    Secretory breast carcinoma is a rare tumor originally described in children but occurring equally in adult population, especially in women. This unusual subtype has a generally favorable prognosis, although several cases have been described in adults with increased aggressiveness and a risk of metastases even death. So far, merely ten cases of secretory breast carcinoma with metastatic axillary lymph node in male were reported. Here, we describe the eleventh case, a 24-years-old male who presented with a painless mass in the right breast was diagnosed to be “secretary breast carcinoma”, and subsequently underwent modified radical mastectomy and adjuvant chemotherapy.

    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

    Gastric endocrine cell carcinoma is a relatively rare tumor. We experienced a case of early gastric cancer in which an endocrine cell carcinoma was identified within a differentiated adenocarcinoma, and a component of this endocrine cell carcinoma had metastasized to lymph nodes of the stomach. In its 2010 revision regarding digestive system tumors, WHO classified cancer cells with characteristics of both glandular system cells and neuroendocrine cells as mixed adeno neuroendocrine carcinoma (MANEC) under the neuroendocrine carcinoma (NEC) category. In this case, we observed an endocrine cell carcinoma continuous with an intramucosal differentiated adenocarcinoma, and cancer cells with an irregular gland duct structure were observed in the proliferative portion of the submucosal tissue. In addition, there was a 35 mm size lymph node metastasis in the lesser curvature of the stomach consisting entirely of poorly differentiated cancer cells with polymorphic, highly atypical nuclei and scant cytoplasm. Immunohistological analysis showed that the endocrine carcinoma in the gastric mucosa was chromogranin A positive and the infiltrated area of the submucosal tissue was also chromogranin A positive. The lymph node metastasis was positive not only for chromogranin A, but also for Synaptophysin and CD56. Furthermore, the Ki67 labeling index was high at approximately 80 % for the gastric endocrine cell carcinoma and approximately 90 % for the lymph node metastases. Until now, there are no reports related to the patients with early gastric cancer accompanied with lymph node metastasis of MANEC. This case is very interested in considering the mechanism of lymph node metastasis of MANEC. The patient has shown no sign of recurrence for 1 year and 4 months after postoperative chemotherapy.

    Medullary thyroid carcinoma accounts for approximately 1 to 2 % of all thyroid carcinoma cases. The most common route of dissemination is to locoregional lymph nodes. Distant metastases commonly affect bones, lungs, and liver. We present a case of a white woman with a 25-year history of medullary thyroid carcinoma on multiple medications including tyrosine kinase inhibitor therapy for the last 11 months, who exhibited unusual diffuse infiltration of advanced stage medullary thyroid carcinoma to her gastric mucosa. A 53-year-old white woman presented with increasing fatigue, loss of appetite, and severe epigastric pain radiating to her back. She had a history of medullary thyroid carcinoma (pT2pN1b), diagnosed 25 years ago and treated by complete thyroidectomy and repeated bilateral cervical lymph node dissection. Medical therapy included octreotide 20 mg every 4 weeks, which was switched to the tyrosine kinase inhibitor vandetanib 300 mg/day 11 months ago when computed tomography scanning revealed progressive mediastinal lymph node and diffuse and symptomatic pulmonary metastases. Of note, she demonstrated macroscopically stable pulmonary and mediastinal lymph node metastases; however, her calcitonin serum levels dramatically increased. Computed tomography scanning revealed a single new intrahepatic lesion (4 mm) as well as multiple (>10) new supraclavicular lesions suggestive of medullary thyroid carcinoma progress. As proven by gastric biopsy and immunohistochemical evaluation, her epigastric pain was explained by a diffuse infiltration of her gastric mucosa by metastatic medullary thyroid carcinoma. Subsequently, she rapidly deteriorated and died. The current case report shows for the first time an unusual metastatic infiltration of the gastric mucosa by medullary thyroid carcinoma. When treating these patients, it is important to include this differential diagnosis during follow-up.

    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.

    BACKGROUND: Metaplastic carcinoma of the breast is a rare but distinct entity within the group of undifferentiated invasive carcinomas. This entity accounts for less than 0.5% of all breast cancers and contains elements of epithelial (ductal), mesenchymal, and intermediate forms of differentiation. Of these metaplastic carcinomas, there have been reports of chondroid, squamous, osseous, and spindle differentiation. CASE REPORT: We describe the clinical course of a 52-year-old female patient with an unusual histopathology of a spindle cell carcinoma of the breast, discuss the literature, and recommend an approach to diagnosis and treatment. The patient initially presented to an outside hospital with a rapidly growing breast mass that was originally diagnosed as a malignant phylloides tumor. She presented 11 months after the primary treatment with a local subcutaneous relapse. She later developed a local relapse of her metaplastic carcinoma in the chest wall. Extensive histopathological analysis lead to the diagnosis of a spindle cell metaplastic breast carcinoma with leiomyoid differentiation, which has not been described previously. CONCLUSIONS: Overlap in morphology can lead to a misinterpretation or underdiagnosis of metaplastic carcinomas. However, the prognosis is similar to more common types of breast adenocarcinoma.

    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.

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.

    Metastases to the pituitary gland and sella turcica are uncommon. The distinction between primary and secondary metastatic pituitary tumours is challenging as carcinomas from distant sites might closely resemble, both clinically and histopathologically, non-functional adenomas or primary pituitary carcinomas. Among metastases to pituitary gland ones from thyroid carcinoma are extremely rare. We present a unique case of a 53-year-old male patient with a past history of thyroid carcinoma who underwent repeated surgeries over a period of 7 years for a sellar-parasellar mass with paranasal sinus involvement. Morphologically, the tumour was composed of solid sheaths of monomorphic cells exhibiting oncocytic features. In electron microscope images, the cytoplasm of tumour cells was filled with numerous mitochondria. The tumour was negative for pituitary hormones but exhibited immunoreactivity for cytokeratin AE1/AE3, thyroglobulin and thyroid transcription factor 1 (TTF-1). Based on the clinical data and immunophenotypic profile, the tumour was finally diagnosed as an oncocytic variant of follicular thyroid carcinoma. To our knowledge, this is probably the first report of such peculiar histopathological variant of follicular thyroid carcinoma metastasizing to the pituitary gland. The diagnostic dilemmas considering oncocytic features of the presented case are discussed.

    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.

    Mixed endometrial carcinoma refers to a tumor that comprises 2 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 ECs (CCC/EC), and 2 mixed CCC and SCs (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 an SC 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 deficiency in both components. A single SC/EC case harbored the same POLE exonuclease domain mutation in both components. One SC/CCC and 1 EC/CCC case showed both shared and unique molecular features in the 2 histotype components, suggesting early molecular divergence from a common clonal origin. In 2 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 morphologic mimicry, whereby tumors with serous-type molecular profile show morphologic features of EC or CCC, 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).

    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.

    Lymphoepithelioma-like gastric carcinoma is a rare type of gastric cancer characterized by a carcinoma with intense stromal lymphocytic infiltration. Although lymphocytic infiltration is closely associated with Epstein-Barr virus (EBV) infection, concomitant occurrence with differentiated adenocarcinoma is relatively rare. The clinical manifestations of lymphoepithelioma-like gastric carcinoma (including EBV-positive and -negative forms) are similar to those of gastric cancer, and the diagnosis is based on pathologic, histologic, and immunohistochemical findings. This report describes the case of a 55-year-old female patient who presented with a 10-year history of recurrent and worsening abdominal pain and melena that had been occurring for 2 mo. An ulcerative lesion was detected in the stomach by endoscopic examination, which raised suspicion of early gastric cancer. A subsequent preoperative endoscopic biopsy showed adenocarcinoma, but the postoperative pathologic, histologic, and immunohistochemical analyses of the resected specimen revealed a final diagnosis of lymphoepithelioma-like gastric carcinoma.

    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.

Imaging revealed diffuse intra-thoracic and intra-abdominal lymphadenopathy. A diagnostic bronchoscopy was performed where an incidental tracheal nodule was discovered and biopsied. Pathology was consistent with epithelial-myoepithelial carcinoma. Lymph node biopsy demonstrated non-caseating granulomas consistent with sarcoidosis. Patient underwent tracheal resection of the primary tumor with primary tracheal reconstruction. Hypercalcemia subsequently normalized with clinical improvement. Repeat CT imaging demonstrated complete resolution of lymphadenopathy. Our findings are suggestive of a possible paraneoplastic sarcoid-like reaction to the epithelial-myoepithelial carcinoma with associated lymphadenopathy and symptomatic hypercalcemia. PMID:26029574

    While it is well known that patients with common variable immunodeficiency (CVID) are predisposed to various malignancies, primarily non-Hodgkin's lymphoma and gastric carcinomas, to our knowledge no cases of hepatocellular carcinoma have been reported in the absence of preexisting liver disease. We report a 50-year-old male patient with CVID with a B- and T-cell deficiency. The patient was on prophylactic intravenous gammaglobulin and had received several years earlier a course of rituximab for an autoimmune disorder. He had no history of hepatitis. The patient developed a rapidly progressing hepatocellular carcinoma within 3 to 4 weeks. Although patients with CVID are predisposed to malignancies such as lymphoma and adenocarcinoma of the stomach, rapidly progressive hepatocellular carcinoma in the absence of any preexisting liver disease has not been described.

    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.

    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.

    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

    We report a case of a primary lymphoepithelioma-like carcinoma (LELC) of the skin. The patient was a 73-year-old man with a lump on his back for 18 months. A biopsy and subsequent excision was performed. He also had axillary node clearance for metastatic disease. The tumor was composed of islands of pleomorphic cells with a lymphocytic infiltrate. Differential diagnoses included squamous cell carcinoma, adnexal carcinoma, Merkel cell tumors, lymphoepithelial lesions, lymphomas, and skin metastases. The histopathologic and immunohistochemical features were those of a LELC of the skin. It was negative for Epstein-Barr virus. Just over 30 cases of primary LELCs arising in the skin have been reported with only 1 documented fatality. We report a case with extensive vascular involvement and bilateral lymph node metastases.

    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

    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.

    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.

    Salivary duct carcinoma is a relatively uncommon aggressive neoplasm, typically found in the parotid glands of older men. The histologic appearance is that of an in situ and invasive high-grade adenocarcinoma, and it closely resembles ductal carcinoma of the breast. Several variants of the latter are very well known, but only papillary, sarcomatoid, and low-grade subtypes have so far been reported in salivary duct carcinoma. This study describes the clinicopathologic and immunohistochemical findings in four examples of an additional previously undescribed variant, rich in mucin. Each tumor showed areas of typical salivary duct carcinoma, but in addition there were lakes of epithelial mucin-containing malignant cells, i.e., mucinous (colloid) carcinoma. All four tumors expressed androgen receptors, cytokeratins, epithelial membrane antigen, gross cystic disease fluid protein-15, and carcinoembryonic antigen, but S-100 protein, other myoepithelial markers, and estrogen and progesterone receptors were negative. The mucin antigen profile showed positivity for MUC2, MUC5B, and MUC6 in all cases but only rare staining with MUC5AC and MUC7. Strong immunohistochemical overexpression of HER2/neu was demonstrated in one tumor, together with amplification by fluorescence in situ hybridization; another case was weakly positive with just one antiserum, but the remaining two tumors were completely negative. Small quantities of mucin have often been described in salivary duct carcinoma but not large extracellular mucinous lakes, which though prominent in the present series, were not as extensive as in mucinous adenocarcinoma. The relatively poor clinical outcome of the patients in our study mirrored that seen in usual-type salivary duct carcinoma and emphasizes the importance of differentiating mucin-rich salivary duct carcinoma from pure mucinous (colloid) adenocarcinoma, a tumor not fully defined, but possibly with a better prognosis.

    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.

    Male breast cancer is rare. The most common histological subtypes include invasive carcinoma "of no special type" and papillary carcinoma. Other variants, including pure micropapillary carcinoma, have been described as well but are extremely rare. Pure micropapillary carcinoma has been recently characterized by a C-MYC gene amplification in women. We report here, occurring in a 73-year-old man, the first case of pure micropapillary carcinoma with amplification of the C-MYC gene. Copyright © 2014 Elsevier GmbH. All rights reserved.

    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.

    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. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Inverted papilloma is a benign epithelial tumor of the nasal cavity. It is known to coexist with malignancy in 5 to 13% of cases, with squamous cell carcinoma being the most common malignancy. Another associated malignancy, one that is extremely rare, is verrucous carcinoma. To the best of our knowledge, no case of verrucous carcinoma occurring alone or in association with another neoplasm has been described in the nasolacrimal system. We report a case of synchronous verrucous carcinoma and inverted papilloma of the lacrimal sac in a 47-year-old man. The patient presented with epiphora, nasal obstruction, swelling of the left medial canthus, and drainage of a foul-smelling fluid from the left nostril. Computed tomography and magnetic resonance imaging detected the presence of a large mass occupying the left nasal cavity and sinuses with extension into the nasopharynx. In addition, bony invasion of the anteroinferomedial wall of the left orbit was noted with extension of the tumor into the orbit itself, which resulted in lateral displacement of the left medial rectus muscle. The patient underwent endoscopic debulking of the left sinonasal lesion. Of note, the surgery had to be completed in stages because of excessive blood loss. Histopathologic examination of the intranasal component of the tumor identified it as an inverted papilloma. One month after the intranasal resection, a left dacryocystectomy was performed; histopathologic examination revealed that an invasive verrucous squamous cell carcinoma had arisen within the inverted papilloma.

  13. 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.

    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.

    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

    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.

    Hypercalcaemic hyperparathyroid crisis is a rare but life-threatening complication of primary hyperparathyroidism. Parathyroid carcinoma is a rare malignancy with an incidence of 0.5% to 4% of all reported cases of primary hyperparathyroidism. We report the case of a 60-year-old Caucasian man with hypercalcaemic hyperparathyroid crisis associated with parathyroid carcinoma. He presented with a classic hypercalcaemic syndrome and his serum calcium and parathyroid hormone levels were at 4.65 mmol/L and 1743 ng/L, respectively. He initially presented with a two-week history of weakness and lethargy and a one-week history of vomiting, polyuria and polydipsia. An emergency left thyroid lobectomy and left lower parathyroidectomy were performed. There was a prompt decrease in his parathyroid hormone level immediately after surgery. Histology revealed that our patient had a 4-cm parathyroid carcinoma. In patients with parathyroid carcinoma, the optimal surgical treatment is en bloc resection with ipsilateral thyroid lobectomy and removal of any enlarged or abnormal lymph nodes. Surgery is the only curative treatment. In our patient, prompt surgical intervention proved successful. At six months the patient is well with no evidence of disease recurrence. This case highlights the importance of considering a hyperparathyroid storm in the context of a parathyroid carcinoma. Parathyroid carcinoma is a rare entity and our knowledge is mainly derived from case reports and retrospective studies. This case report increases awareness of this serious and life-threatening complication. This report also illustrates how prompt and appropriate management provides the best outcome for the patient.

  18. Clinicopathological features of infiltrating lobular carcinomas comparing with infiltrating ductal carcinomas: a case control study

    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

    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.

    2017-01-01

    Background Metastatic carcinoma to the jaws and oral region are very rare, representing less than 1% of all oral tumors. Unfortunately, oral metastasis is usually manifestation of an advanced stage of primary cancer, and indicates widespread disease and poor prognosis. Material and Methods In this retrospective study, a total of 2039 patients with history of oral malignant tumor between 1980 and 2012 at Seoul National University Dental Hospital were evaluated. We analyzed the dental and medical records, and histopathological database of 2039 patients to assess the prevalence of oral metastasis of carcinoma in terms of sex and age, as well as, the most common origin of primary cancer, and prevalent site and histopathological type of metastatic carcinoma. Results Among 2039 patients, 21 (1.03%) were finally diagnosed with metastatic carcinoma of the jaws and oral region. Among the 21 patients, only 11 had a working diagnosis as oral metastasis upon clinical evaluation before performing a biopsy. The mean age at the time of diagnosis with a metastatic carcinoma was 56.86, and there was a male preponderance. Metastatic carcinoma was more frequent in the jaws than in the soft tissue, especially in the mandible compared to the maxilla. The most frequent primary site was the lungs, followed by the liver and breasts. The predominant histopathological types were hepatocellular carcinoma and adenocarcinoma. Patient outcomes indicated a poor prognosis with the time from the appearance of the metastasis to death was only 12 months. Conclusions According to these cases, oral metastases of carcinoma were exceedingly rare in Koreans. It can allow the clinicians take into account the possible presence of metastases and lead to early diagnosis. Key words:Metastasis, jaws, oral region, mandible, Korean. PMID:28390123

    Small cell carcinoma (SCC) of the pancreas is rare. It has similar histological features to pulmonary small cell carcinoma and is equally aggressive. Most patients with SCC in the pancreas reported in case studies died within 1 year after diagnosis. We present a case of unusually long-term survival after surgery and combined chemotherapy for SCC of the pancreas. A 62-year-old woman presented with epigastric pain and jaundice. Computed tomography revealed dilated common bile duct caused by external compression of the mass in the pancreatic head. Exploratory laparotomy and pancreaticoduodenectomy (PPPD) was performed with histopathological analysis confirming a primary small cell carcinoma of the pancreas. After an uneventful postoperative recovery, the patient was treated with 6 cycles of combined chemotherapy consisting of cisplatin and ectoposide. During the follow-up, there was no evidence of recurrence and the patient has remained in a good health condition for 36 mo since the diagnosis. PMID:18756608

    Cutaneous squamous cell carcinoma is the second most common form of skin cancer and accounts for 20% of cutaneous malignancies. We report the case of a patient who presented with a complaint of nonhealing wounds following radiation therapy for the treatment of noninvasive squamous cell carcinoma of both lower extremities. Initial biopsies of the wounds were benign. However, a second biopsy performed approximately 2 months later was found to be positive for invasive squamous cell carcinoma. This case uniquely exemplifies that all nonhealing wounds should be viewed with a critical eye for possible malignancy even in the presence of previous negative biopsy. This is especially true for radiation wounds that may be prone to malignant transformation or recurrence.

    Ameloblastic carcinoma is a rare malignant odontogenic neoplasm that can arise either as a de novo lesion or from pre-existing ameloblastoma. Histopathologically, the tumor retains an ameloblastomatous differentiation pattern but shows cytological features of malignancy. Owing to variable biologic behavior and paucity of long-term follow-up cases, there has been no clear consensus on treatment protocol. The present case of ameloblastic carcinoma arose in the mandible of a 24-year-old male. Surgical treatment involved resection of the mandible along with regional lymph nodes. The patient has been on follow up for the past one year without any recurrence or metastases. An update on ameloblastic carcinoma encompassing the histogenesis, immunohistochemical features and treatment aspects are included. PMID:25364189

    Glassy cell carcinomas are composed of malignant cells showing a "ground glass" cytoplasm, distinct cell membranes, and large nuclei with prominent nucleoli. To our knowledge, only 12 cases of glassy cell endometrial carcinomas (EGCC) have been reported until now. A 63-year-old patient complaining of irregular vaginal bleeding underwent hysteroscopy-guided biopsy revealing a well-differentiated endometrial endometrioid adenocarcinoma. The patient underwent left salpingo-oophorectomy, total abdominal hysterectomy, and pelvic lymphadenectomy. The final diagnosis was FIGO stage IB poorly differentiated endometrial adenosquamous carcinoma with > 90% of glassy tumor cells. The patient is alive, with no evidence of disease for 69 months after diagnosis. We describe an additional case of EGCC and review the data of the literature, emphasizing the need to strictly define the criteria for the diagnosis and the potential usefulness of assessing biologic parameters for the prognostic characterization of this rare entity.

    2000-12-01

    Primary intraosseous salivary gland tumors are rare, with mucopidermoid carcinoma being the most frequent histotype. The authors present a case of adenoid cystic carcinoma, located in the mandibular incisor region, associated with pain. Endodontic treatment resulted in increased pain and progressive mandibular expansion. An apicoectomy was conducted, and an intraosseous adenoid cystic carcinoma was diagnosed at histological examination. The patient was treated by wide surgical resection, and is alive and well without recurrences or distant metastases 14 yr after the original diagnosis. The case presented herein calls attention to the preoperative clinical diagnosis of periapical lesions. Radiologically, focal sclerosing osteitis, cementoblastoma, cementifying and ossifying fibroma, periapical cemental dysplasia, complex odontoma, and calcifying epithelial odontogenic tumor should be considered in the differential diagnosis. In addition the unusual occurrence of salivary gland tumors in intraosseous location stresses the importance of systematic histological examination of any tissue sample obtained after endodontic procedures.

    2016-01-01

    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

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

    PubMed Central

    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.

    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.

    Data from 150 patients with laryngeal carcinoma, consecutively treated primarily by radiotherapy from 1965 through 1974 was analyzed to assess the quality of voice. The voice appears to improve in majority of the successfully irradiated patients. In 76% of the evaluable patients in this group, the quality of voice appears to have attained normalcy or near normalcy. Smoking appears to have a negative influence. High incidence of bronchogenic carcinoma along with the negative influence of smoking on the quality of voice in this series of patients indicate that the patients should be advised against smoking in day-to-day clinical practice.

    Cancer procoagulant (CP) is a sulfhydryl proteinase thought to be synthesized mainly by neoplastic cells. Consequently, increased CP activity in blood serum was interpreted as being associated with the presence of a proliferative process in the host's body. To date, CP activity has not been systematically studied in cases of genital carcinoma. The present study is aimed at evaluation of CP activity in women with genital carcinoma. A case-controlled study backed up by histopathological examination. Peripheral blood was sampled preoperatively in a sterile manner from an antecubital vein, from 16 women with cervical carcinoma and 15 women with uterine carcinoma. Blood for the reference group of 12 healthy women was obtained in an identical manner after an overnight fast. The CP activity in serum was determined using the coagulative method according to Gordon and Benson, and was expressed as coagulation time in seconds (s). The CP activity in 10% tissue homogenates (in saline) of genital cancer was determined by the chromogenic method according to Colucci et al. The mean CP activity in serum of women with cervical carcinoma (78.28 +/- 15.25 s) and of women with uterine carcinoma (79.63 +/- 12.02 s) was significantly different (P < 0.0001) from the respective values found in healthy women (281.33 +/- 43.19 s). The CP activity in neoplastic tissue was 28.50 +/- 6.40 nmol pNa/mL for cervical carcinoma, and 28.31 +/- 3.92 nmol pNa/mL for uterine carcinoma, both values being significantly higher (P < 0.0009) than the activity found in the normal tissues. There was no established relationship between neoplastic CP activity and FIGO staging of the disease. This is the first study to demonstrate the concomitant presence of CP activity in serum and neoplastic tissue of women with genital carcinoma. These patients have decreased coagulation time and thus are likely to develop coagulation disturbances in the course of their cancer. There may be a role for CP as a tumor marker of

    Verrucous carcinoma is a slow-growing tumor with 3 main localizations: Oral cavity, ano-urogenital region, and plantar surface of the foot. On the sole it may rise adjacent to viral warts and very often is mistaken for the common verruca plantaris. Although both conditions-viral warts and cutaneous squamous cell carcinoma-are often diagnosed in immunosuppressed patients, in literature we have found only 3 case reports of verrucous carcinoma in organ transplant recipients. We present a case of 26-year-old man after deceased donor renal transplantation with plantar verrucous carcinoma successfully treated with excision and 5% imiquimod.

    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.

    Acinar cell carcinoma represents only 1-2% of exocrine pancreatic neoplasms. On exceptionally rare occasions, primary acinar cell carcinoma can occur in ectopic locations. Herein, we report a case of pure pancreatic-type acinar cell carcinoma arising in the stomach. A 54-year-old male presented with a gastric submucosal mass detected by endoscopic examination. Laparoscopic wedge resection was performed. Macroscopically, the 2.7 cm yellowish mass was located in the submucosa of the stomach. Microscopically, the tumor was well circumscribed and had a homogeneous acinar architecture. The tumor cells were small and had a minimal amount of cytoplasm. The nuclei of the tumor cells were round to oval with finely dispersed chromatin. The tumor cells were strongly positive for α1-antitrypsin, chymotrypsin, and α1-antichymotrypsin immunostaining, consistent with pancreatic exocrine differentiation. There was no clinical or radiologic evidence of primary pancreatic or head and neck tumors. After surgical resection of the tumor, there was no recurrence or metastasis during 33 months follow-up. In this report, we have presented a rare case of primary pure pancreatic-type acinar cell carcinoma arising in the stomach and suggest that it could be helpful if the pathologist were aware that pancreatic-type acinar cell carcinoma could arise in the stomach as a polypoid submucosal tumor in the routine diagnostic field of gastric endoscopy.

    Verrucous carcinoma of the foot is often misdiagnosed initially as plantar warts. Delayed diagnostic treatments with the use of optimal biopsy techniques may result in significant hindrances for patient care and may often result in detrimental outcomes to the patient. With the use of various epidermal biopsy methods, early diagnostic treatment can be implemented to a slow-growing lesion unresponsive to topical agents preventing unfavorable pedal amputations. A case study of verrucous carcinoma of the foot with surgical resection was conducted along with a literature review. Verrucous carcinoma (VC) of the foot is known to be a rare, locally invasive, well-differentiated low-grade squamous cell carcinoma that may evolve from the human papilloma virus. This localized tumor of the foot often has low metastatic potential, however can be quite invasive. It is therefore pertinent to obtain adequate radiological studies when planning for surgical resection of this tumor. When localized to the foot, it often involves deep structures such as tendons, muscle & bone. Complete wide local excision of the tumor is essential to avoid recurrence. We present a case of verrucous carcinoma of the foot in a 46-year-old African American male with a past medical history of Human immunodeficiency virus (HIV) and Human papilloma virus (HPV). The patient refused a Transmetatarsal amputation. The loss of the third digit was a result of tissue loss following resection and an attempt to relocate a severely laterally dislocated 3rd digit, not PVD. Published by Elsevier Ltd.

    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

    Of fifty two children with nasopharyngeal tumors who were registered and treated a Memorial Sloan-Kettering Cancer Center (MSKCC), from 1961 through 1977, 16 had carcinoma. The results of retrospective analysis of these patients are presented here. There were 7 girls and 9 boys between 12 and 16 years of age. One patient had a Stage I tumor; one had a Stage II tumor and 14 had Stage IV tumors. The histology was poorly differentiated epidermoid carcinoma in all patients. All patients had radiotherapy to the primary site. Six patients received chemotherapy for distant metastases, and 2 had adjuvant chemotherapy. Of the 13 patients who were treated initially with radiation alone, 2 were alive and free of disease at 12 and 14 years respectively. Of the 3 patients who had chemotherapy at initial treatment, one was alive and free of disease 18 months from diagnosis and one patient died of treatment without tumor. Bone was the common site of distant metastases. While radiation therapy alone appears to be adequate treatment for early tumors, adjuvant chemotherapy should be tried to improve results in advanced tumors.

    The most common congenital anomaly of the pancreas is pancreatic divisum (Tadokoro et al. in Anat Res Int 2011:1-7, 2011). Agenesis of the dorsal pancreas is extremely rare (Schnedl et al. in World J Gastroenterol 15(3):376-377, 2009). We are reporting a case of agenesis of dorsal pancreas presented with ampullary carcinoma.

    2010-01-01

    Primary peritoneal carcinoma (PPC) is a relatively uncommon malignancy, and its presentation is similar to that of advanced ovarian serous carcinoma. There have been afew case reports in which the malignant cells from PPC were discovered from routine Papanicolaou (Pap) smears. In 2006 a 49-year-old, asymptomatic female participated in the Hospital Health Fair. High grade adenocarcinoma was found by Pap smear. After negative cervical and endometrial curetting and loop electrosurgical excision procedure cone, laparoscopy revealed widespread peritoneal carcinomatosis. The subsequent surgical specimens showed primary peritoneal serous carcinoma. Although the Pap smear was originally designed to detect premalignant cervical lesions and cancer, it became apparent that malignant cells from extrauterine primaries might appear in the smears. This case illustrated the value of the Pap smear in discovering unsuspected extrauterine malignancies, including PPC. Review of 9 cases showed tumor cells in the fallopian tube lumen in 4 out of 9 cases, indicating the likely route of efflux of tumor cells to appear in the Pap smear. The new concept of serous tubal intraepithelial carcinoma as the origin of PPC suggests another source of tumor cells in Pap smears.

    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.

    Ameloblastic carcinoma is a rare malignant odontogenic tumor. Here we present a case of a large ameloblastic carcinoma, which developed in a preexisting ameloblastoma in the right submandibular region. The patient was an 84-year-old woman who had received several surgical procedures for ameloblastoma, including a segmental mandibulectomy. The dimensions of the tumor were 12 × 8 × 5 cm, and both benign ameloblastoma and ameloblastic carcinoma were observed histologically. Based on histologic diagnosis, immunohistochemical staining and sequence analysis for p53 were performed. Overexpression of p53 was observed only in the ameloblastic carcinoma. Additionally, a mutation of the p53 gene (TP53) in exon 5 was found by sequence analysis in the ameloblastic carcinoma. This is the first case of ameloblastic carcinoma with a mutation of the p53 gene that has been associated with carcinomatous transformation. Copyright © 2014 Elsevier Inc. All rights reserved.

    Stratified mucin-producing intraepithelial lesion (SMILE) is considered to be a variant of adenocarcinoma in situ (defined as intraepithelial malignant glandular epithelium without invasion) or adenosquamous carcinoma in situ of the uterine cervix. However, recent study suggested that SMILE is more similar to high-grade squamous epithelial lesion by their immunohistochemical findings. An invasive form of SMILE "invasive stratified mucin-producing carcinoma (ISMC)" has been also proposed, but immunohistochemical features are not well documented. Therefore, this study aimed to clarify the immunohistochemical characteristics of SMILE and ISMC. Twelve cases of SMILE were found among 445 patients (2.7%) with high-grade intraepithelial lesions or invasive carcinomas, 3 of whom had solely intraepithelial disease with SMILE component (mean age, 37 years; range, 30-48 years) and 9 with invasive carcinomas (mean age, 47 years; range, 37-66 years; including ISMC). Immunohistochemically, SMILE and ISMC were diffusely positive for p16 and CAM5.2, focally for IMP3, and almost negative or only focally positive for p63. Nuclear signals in SMILE and invasive carcinomas were detected by human papillomavirus (HPV) in situ hybridization; 5 cases showed HPV16 and/or HPV18 polymerase chain reaction products. The ultrastructural study of 1 case showed surface microvilli and small vacuolar structure in SMILE; ISMC had mucous-like vacuoles, many mitochondria and intracytoplasmic lumen but lacked tonofilament. These findings were more similar to adenocarcinoma in situ or adenocarcinoma than squamous intraepithelial lesion or squamous cell carcinoma. We suggest that SMILE is an intraepithelial neoplasm and ISMC is an invasive form of SMILE. Copyright © 2016 Elsevier Inc. All rights reserved.

    Lymphoepithelioma-like carcinoma (LELC) of the breast is an exceedingly rare variant of mammary cancer. To our knowledge, only twenty - one cases have been reported in the literature. Diagnosis of this type of mammary carcinoma may be challenging, owing to its rarity and the histopathological similarity to common inflammatory and malignant lesions of the breast mainly granulomatous mastitis, medullary carcinoma, pleomorphic lobular carcinoma, lymphoma and other hematological malignancies. Our case is the 22nd case of lymphoepithelioma-like carcinoma reported in the breast, presenting with a palpable tender mass in a post-menopausal female. Her clinical picture had been mistaken for inflammatory disease. We present our case, with its detailed clinical history, radiological findings, histopathological and immune-histochemical findings along with a review of the literature. Highlighting this type of tumors may help in appropriate diagnosis. Moreover, studying the behavior of these rare neoplasms is essential to expedite treatment for this tumor type.

    Discoid lupus is an autoimmune disorder with primarily cutaneous manifestations. Carcinomatous changes in discoid lupus can lead to the development of squamous cell carcinoma. While this most often occurs in Caucasians, the presented patient is an African American. She developed numerous squamous cell carcinomas in areas of scarring from discoid lupus. This case illustrates the need for careful observation of discoid lupus for the development of squamous cell carcinoma in the African American patient.

    We report a case of basal cell carcinoma that appeared from an epidermal verrucous nevus in a 61-year-old patient. The onset of basal cell carcinoma in sebaceous nevi, basal cell nevi and dysplastic nevi is relatively common, but it is rarely associated with epidermal verrucous nevi. There is no consensus on whether the two lesions have a common cellular origin or whether they merely represent a collision of two distinct tumors. Since this association – as with other malignant tumors – is rare, there is no need for prophylactic removal of epidermal verrucous nevi. PMID:25848348

    This report describes a rare case of coexistence of benign phyllodes tumor, which measured 9 cm in the right breast, and invasive ductal carcinoma of 6 cm in the left breast, synchronous and independent, in a 66-year-old patient. The patient underwent a bilateral mastectomy due to the size of both lesions. Such situations are rare and usually refer to the occurrence of ductal or lobular carcinoma in situ when associated with malignant phyllodes tumors, and more often in ipsilateral breast or intra-lesional.

    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.

    We report a patient who had an oat cell bronchogenic carcinoma in association with the syndrome of inappropriate antidiuresis. There was an unusually long interval between the onset of hyponatraemia and clinically evident malignant disease. Dynamic testing of vasopressin secretion showed preservation of baroregulated, but not osmoregulated, vasopressin release. Immunoreactive vasopressin was detected in pleural fluid, which co-eluted with synthetic vasopressin on gel chromatography. PMID:6306627

    A third to half of penile invasive squamous cell carcinomas are human papillomavirus (HPV) related. Warty (condylomatous), warty-basaloid, and basaloid carcinomas are the most common subtypes associated with HPV. Less frequent are clear cell and lymphoepithelioma-like carcinomas. Here we report a novel penile tumor associated with HPV. 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.

    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

Since FDG-PET showed no evidence of metastasis, we performed cholecystectomy, hepatectomy of S4a/5, and regional lymph node dissection. The immunohistochemical study of the specimen was positive for CK7, CK20, chromogranin A, and synaptophysin. The Ki-67 labeling index was 50%, and the SSTR2 score was 2+. The patient was diagnosed with neuroendocrine carcinoma. Since she was in poor condition and on hemodialysis, we started administration of somatostatin analog at the time of recurrence, and soon her diarrhea improved but the tumor increased in size.

    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.

    Aim of the study Thyroid carcinoma is the most common malignancy of endocrine organs. The prognosis varies. Factors such as age, sex, size of the tumor, stage of disease, presence of extrathyroidal spread, and completeness of resection have been found to significantly influence prognosis. We aimed to evaluate clinical features of our patients with thyroid carcinoma, prospectively. Material and methods We evaluated total 178 patients treated between 2010 and 2011 at the Department of Endocrinology, İzmir Atatürk Training Hospital, retrospectively. Data on patients, tumors, and therapeutic approaches were collected. All results are shown as mean ± standard deviation (SD). P values were based on two-sided tests with a cutoff for statistical significance of 0.05 and 95% confidence interval. Results There were no differences between female and male patients according to histopathological subtypes, demographic data and prognostic findings of thyroid cancer. The assessment of tumor size and other prognostic factors revealed that there was a correlation between tumor size and capsular and/or vascular invasion. In the postoperative evaluation we detected a correlation between metastases and vascular invasion and/or capsular invasion but there was no significant relation between focus (solitary/multifocal) and metastases. Conclusion There was no significant difference in terms of gender and age (< 45 years of age and ≥ 45 years of age) among the patient groups (low risk/intermediate risk/high risk). By multiple regression analysis among metastasis and prognostic factors it was observed that vascular invasion and thyroglobulin levels affect development of metastases. PMID:23788883

    A woman in her 60s was referred to our hospital with a superficial depressed lesion measuring 8mm in diameter on the lesser curvature of the lower gastric body. Initial biopsy of the lesion indicated a moderately differentiated adenocarcinoma. Endoscopic submucosal dissection was performed, and pathological examination revealed a tumor comprised of adenocarcinoma and neuroendocrine carcinoma with submucosal infiltration, with the final pathological diagnosis being gastric mixed adenoneuroendocrine carcinoma (MANEC). Laparoscopic gastrectomy was subsequently performed. No recurrence was observed after 18 months. Most neuroendocrine carcinomas including MANEC are diagnosed at an advanced stage and require surgical resection. Here we report a case of gastric MANEC mimicking early gastric cancer that was removed en bloc via endoscopic submucosal dissection.

    Temporal bone carcinoma is an aggressive tumor with multiple unconfirmed risk factors. Herein, we present a rare case of a primary petrous bone carcinoma in a female patient (65 years old) with an irrelevant medical history. She presented a postauricular swelling that revealed a multilocular osteolytic cystic lesion of the mastoid portion of the temporal bone on the CT scan. The patient underwent resection of the lesion and pathological analysis revealed moderately to well-differentiated squamous cell carcinoma. Postoperative radiotherapy was carried out. Until the present time, the patient shows complete remission on regular clinical and radiological follow-up. Although no widely accepted strategy for managing temporal bone tumors exists, a review of the literature showed that surgery with or without radiotherapy is the treatment of choice. Preoperative assessment and accurate staging are vital in ensuring that the treatment is adequate for each disease stage. © 2014 Wiley Periodicals, Inc.

    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.

    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. Copyright © 2016 Sociedade Brasileira de Microbiologia.

    Intraosseous verrucous carcinoma (IOVC) arising from an odontogenic cyst is extremely rare. We report a case of intraosseous verrucous carcinoma in a 74-year-old male who presented with a left mandibular swelling with recurrent pus discharge from gingiva of tooth #35. Panoramic radiography revealed an impacted tooth #34 and a large well-defined, radiolucent lesion surrounding the crown of tooth #34. The clinical diagnosis was an infected dentigerous cyst. Surgical excision of the cyst together with extraction of tooth #34 was performed. Histopathological examination showed proliferation of hyperparakeratotic stratified squamous cyst lining epithelium and down-growth of broad and bulbous epithelial ridges with pushing border invasion into the fibrous cystic wall. A verrucous carcinoma arising from an infected dentigerous cyst was diagnosed. There was no recurrence of the tumor 5 months after surgery. Copyright © 2012. Published by Elsevier B.V.

    Verrucous carcinoma is a slow-growing lesion that is most often found on the weight-bearing surface of the foot and should be considered in the differential diagnosis for chronic nonhealing wounds in the diabetic neuropathic population. Accurate diagnosis may be difficult initially and often requires repeat histopathologic evaluation by an experienced pathologist. Verrucous carcinoma can invade deeper tissues; however, extension to bone is a rare occurrence. The authors present a case report of an atypical verrucous carcinoma on the dorsal aspect of the foot and a review of the literature. Studies suggest that multiple therapies exist and recurrence does occur; however, this is less likely with wide excision and more so with Mohs' surgery. With a high clinical suspicion and thorough histopathologic exam, bone involvement and amputation may be avoided. Therapeutic, Level IV.

    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

    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.

    Bowel metastasis secondary to renal cell carcinoma causing intussusception is very rare condition. Here a case of a 52-year-old male, who presented with signs and symptoms of small bowel obstruction is reported. CT abdomen showed small bowel obstruction due to ileo-ileal intussusception and left renal mass. On exploratory laparotomy Ileo-ileal intussusception was present. FNAC taken from left kidney at same sitting. Histology of resected specimen reported metastatic nodule in small bowel of renal cell carcinoma. FNAC confirmed primary renal cell carcinoma of left kidney. Although abdominal CT scanning provides the most reliable indications, it is laparotomy, that establishes the diagnosis of intussusception, and the histological examination that determines the cause.

    Plasmocytoma solitare is a rare disease of lymphoprolipherative origin. It is usually diagnosed occasionally on ORL departaments because of its close relation to head and neck localisation. Surgical treatment and/or radiotherapy is a treatment of choice. It becomes disseminated after years usually. Carcinoma of larynx is a squamos cell carcinoma of well known ethiology strongly corralated with alcohol and nicotin abuse. There is described a case of patient in this paper, who in a short time of few months developed two neoplasms of different histological origin, but localised in the same region of head and neck: Plasmocytoma solitary of uvulae and carcinoma of larynx. Due to early diagnoses the radical treatment (combined surgery and radiotherapy) was performed. However the extremly short time of follow up do not allow to make the observation of the DFS and OS of the patient.

    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).

    Invasive squamous cell carcinoma of the vulva is primarily a disease of postmenopausal women and thus is rarely associated with pregnancy. We have reported on a young woman under 40 years old with vulvar carcinoma, which occurred during the pregnancy but optimal treatment was delayed to the postpartum period. This 37-year-old woman was diagnosed with 3x3 cm vulvar lesion, 2 weeks after cesarean section, subsequent biopsy revealed squamous cell carcinoma. She had a history of an ulcer on her left labia minor at the third month of the pregnancy. She was treated by a modified radical vulvectomy and bilateral groin lymphadenectomy. She did not receive any additional treatments. Now after two years, she has had no recurrence of the disease. This case emphasizes on the need to consider malignancy as a differential diagnosis in vulvar lesions of pregnant young women.

    We report a case of papillary carcinoma of the thyroid gland and cervical lymph node metastases with concurrent tuberculous lymphadenitis that was diagnosed preoperatively. A 35-year-old woman presented with multiple lymph node swellings and an anterior neck mass. No findings suggesting the coexistence of pulmonary tuberculosis were present. The patient underwent a total thyroidectomy with bilateral neck dissection together with medication. Measures to prevent tuberculosis were undertaken during the perioperative period. The histopathological diagnosis was papillary carcinoma with both metastatic and tuberculous lymphadenitis of the lymph nodes in the neck. The possible coexistence of tuberculous lymphadenitis must be ruled out when lymph node swellings are observed in patients with head and neck cancer, including thyroid carcinoma.

    Gall bladder tuberculosis is very rare and curable but, sometimes can be confused with the clinical diagnosis like carcinoma. A 32-year-old male presented with acute pain in right abdomen for one month and fever off and on for two months. CT scan (whole abdomen) showed features suggestive of lymphadenopathy although peroperatively no significant lymph node could be identified but there were multiple white patches on gastrohepatic ligament and neck of gall bladder probably which were identified as lymph nodes on scanning. On the basis of peroperative findings clinician diagnosed it as a case of carcinoma gall bladder and was subjected to cholecystectomy. On histopathological examination it turned out to be tuberculosis gall bladder. Therefore tuberculosis of gall bladder can mimic carcinoma clinically.

    A 69-year-old woman was admitted to our hospital with the complaint of a right breast mass. As a result of thorough examinations, she was diagnosed with breast cancer and underwent breast-conserving surgery. The pathological findings of the resected specimen showed that the tumor consisted of intermingled carcinomatous and sarcomatous components with a transition zone. On immunohistochemical study, the sarcomatous cells in this transition zone showed partial positive staining for CD10, the myoepithelial marker, suggesting that the myoepithelial cells had transformed into sarcoma, and then this biphasic tumor was formed. Finally, she was diagnosed with biphasic metaplastic sarcomatoid carcinoma of the breast. Biphasic metaplastic sarcomatoid carcinoma of the breast is a relatively rare but aggressive disease. The pathological diagnosis is often controversial, requiring detailed immunohistochemical analysis. We report our experience with a case of biphasic metaplastic sarcomatoid carcinoma of the breast.

    Fibroadenomas are a type of benign tumor that occur in young women below the age of 35 years old. The tumors are the second most common type of tumor after fibrocystic disease. The chance of carcinoma arising in a fibroadenoma is extremely low. To date, <130 such cases have been reported. Previous studies have reported that fibroadenomas can evolve into a number of different types of malignancy. The present study is the first to describe a case of bilateral primary breast cancer with a unilateral invasive ductal carcinoma within a fibroadenoma. The current study presents a case of a 48-year-old female who presented with 2 stiff lumps on bilateral breasts, diagnosed as bilateral breast carcinoma, with a unilateral invasive ductal carcinoma within a fibroadenoma in the right breast. The patient underwent a bilateral mastectomy and subsequently received 4 cycles of chemotherapy (epirubicin, 60 mg/m2 and cyclophosphamide, 600 mg/m2) every 21 days, followed by 4 cycles of docetaxel chemotherapy (100 mg/m2) every 21 days. The patient then received maintenance endocrine therapy (tamoxifen, 20 mg, twice daily) for 19 months. The patient was followed up every 3 months, and at the last follow-up examination in May 2015, the patient exhibited no signs of recurrence. PMID:26622700

    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.

    Introduction Primary signet cell carcinoma of the cervix has been reported only in 18 cases to date. Presentation of case A 48-year-old woman was seen at our Gynecologic Oncology Unit, because she complained postcoital bleeding during the last three months. She had 1–2 cm cervical mass, originating from the endocervical canal. A biopsy revealed a signet ring cell-type adenocarcinoma. Suspected primary sites were excluded after gastroscopy, colonoscopy and mammography. The patient underwent a laparoscopic type-3 radical hysterectomy with bilateral salpingo–oophorectomy, pelvic lymph node dissection and paraaortic lymph node dissection with a presumed diagnosis of primary signet ring cell carcinoma of the cervix. Microscopically, the tumour consisted of 70% signet ring cell type and 30% endocervical adenocarcinoma. She did not receive any adjuvant treatment. Follow-up at 18 months after surgery showed no evidence of recurrence. Discussion Nineteenth case of a primary signet ring cell carcinoma of the cervix was presented. Immunohistochemical studies and HPV DNA positivity may help in diagnosis. Conclusion It is crucial to differentiate primary tumour from metastatic signet cell carcinoma, while treatment and prognosis differ significantly. PMID:26874582

    Basal cell carcinoma is the most common type of skin cancer in humans. The aim of our study was to determine the histologic risk factors involved in recurrence of basal cell carcinomas of the face. We conducted a retrospective study of patients with primary basal cell carcinoma (BCC) of the face treated between March 2003 and December 2005. We analyzed the size of lateral and deep margins of tumor, histologic subtype, perineural invasion, and ulcerations. Clinical follow-up was observed until June 2011. We note that 184 cases of BCC were included. Eleven recurrences occurred during the follow-up, i.e. 6%. The population was divided into two groups according to histologic safety margins (1 mm for all basal cell carcinomas, 0.8 mm for nodular and 2 mm for aggressive-growth (AG-BCC) subtypes). There was a significant difference between groups in regards to cancer recurrence. Tumor size above 2 cm and presence of perineural invasion increased the risk of recurrence. Low histological safety margins appear to be critical on tumor recurrence. Depending on the tumor characteristics, and the patient, we advocate a re-excision in cases of histological safety margins inferior to 0.8 mm for the nodular subtypes and 2 mm for aggressive subtypes. Tumor size, and perineural invasion should be taken into consideration so as to make a well-informed decision between re-excision and a watching strategy in critical cases.

    Most colon cancers are adenocarcinoma of the colon, which present with a typical histological type. However, a relatively newly-recognized subtype, called medullary carcinoma of the colon, has been characterized. This type is generally divided into subtypes of poorly-differentiated and undifferentiated medullary carcinoma. Only a handful of studies have been conducted thus far, mostly focusing on immunohistochemical and clinical characteristics of the disease. Herein we present two cases seen at our hospital within one academic year. The first is the case of a 79-year-old African-American woman, who presented with generalized weakness and gait unsteadiness ultimately diagnosed with a Stage IIIB medullary carcinoma of the proximal colon at the time of surgery, but later found to have metastases to a single paraesophageal lymph node. The second is a case of a 79-year-old Caucasian woman, who presented with several weeks of malaise, nausea, and diarrhea leading to diagnosis of a stage IIB medullary colon carcinoma now receiving chemotherapy. Although these tumors tend to be right-sided and therefore present at an advanced stage, distant metastasis is rare at presentation and is primarily to the liver or regional lymph nodes. Only one study has been performed regarding short-term outcomes, which failed to reach statistical significance, but trended towards better prognosis compared to poorly-differentiated and undifferentiated colonic adenocarcinomas.

    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.

    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.

    Cervical cord compression secondary to extension of a long standing papillary thyroid carcinoma as well as multiple cases of distal cord compression from occult follicular thyroid carcinoma have been reported. But cervical cord compression from Papillary Thyroid Carcinoma has not been reported so far. Forty eight year old lady presented with progressive quadriparesis of 2 months duration. MRI of the cervical spine showed destructive lesion with soft tissue component in vertebral bodies and posterior elements of C4-C6 vertebrae with cord compression along with a large thyroid mass extending to retrosternal region likely malignant. USG guided FNAC & Biopsy of thyroid lesion was inconclusive. She underwent Preoperative Selective angioembolisation for vertebral metastasis followed by total thyroidectomy with cervical cord decompression, bone grafting and plating. HPE reported follicular variant of Papillary Thyroid carcinoma. Four weeks postoperatively she underwent radioiodine ablation by 263 mci of I 131. She then received palliative EBRT to cervical and dorsal spine 30 Gy/10 fractions. She is alive and neurologically stable at 6 months follow up. Papillary thyroid carcinoma has an excellent prognosis. Hence a prompt management of primary disease and aggressive approach to metastatic lesion may prolong survival and allow favorable prognosis.

    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.

    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.

    A 65-year-old female patient reported with a chief complaint of swelling in the left lower region of the jaw since two years. On clinical examination, the swelling was present on the mandibular left posterior region and measuring approximately 6.2 cm antero-posteriorly × 6.2 cm mediolaterally × 8.7 cm superioinferiorly. Initially, it was non tender but eventually it became tender. Fine needle aspiration was done to rule out any salivary gland pathology and report obtained was carcinoma ex pleomorphic adenoma. Then, excisional biopsy was taken and tissue sent for histopathology. Histopathological diagnosis was benign adenoma with carcinoma. Later serial sections of tissue were studied and came to the conclusion of carcinoma ex pleomorphic adenoma which was non invasive type and showed bizarre cells with neoplastic changes. Benign part was composed of myxomatous area with partial capsule. Neoplastic cells showed invasion into capsule and few necrotic areas were also present. Overall interpretation was favoured Non invasive carcinoma ex pleomorphic adenoma. So here, we reported a case of Carcinoma ex Pleomorphic Adenoma (CAEXPA) which is a deadly and rare variant of salivary gland malignancy. PMID:28658924

    A 65-year-old female patient reported with a chief complaint of swelling in the left lower region of the jaw since two years. On clinical examination, the swelling was present on the mandibular left posterior region and measuring approximately 6.2 cm antero-posteriorly × 6.2 cm mediolaterally × 8.7 cm superioinferiorly. Initially, it was non tender but eventually it became tender. Fine needle aspiration was done to rule out any salivary gland pathology and report obtained was carcinoma ex pleomorphic adenoma. Then, excisional biopsy was taken and tissue sent for histopathology. Histopathological diagnosis was benign adenoma with carcinoma. Later serial sections of tissue were studied and came to the conclusion of carcinoma ex pleomorphic adenoma which was non invasive type and showed bizarre cells with neoplastic changes. Benign part was composed of myxomatous area with partial capsule. Neoplastic cells showed invasion into capsule and few necrotic areas were also present.

    Renal cell carcinoma is the most frequent malignant neoplasia of the kidney accounting for 90 % of all renal solid tumors. Metastases from renal cell carcinoma are rarely located in the small bowel and generally their clinical presentation includes bleeding and obstruction. Intussusception in adults is an extremely rare pathological condition and only 30 to 35 % of small bowel intussusceptions are derived from malignant lesions. We report here a clinical case of a 75-year-old white man hospitalized for anemia and subocclusion. An abdominal ultrasound and computed tomography showed a small bowel intussusception. During a surgical exploration, a polypoid lesion was found to be the lead point of the intussusception. His small intestine was resected and a functional side-to-side anastomosis was performed. The histological features of the surgical specimen confirmed the diagnosis of metastatic renal cell carcinoma. Small bowel intussusception from renal cell carcinoma metastasis should always be considered in the setting of unexplained intestinal subocclusion in patients with a history of renal cell carcinoma.

    A 65 year-old male patient with a one year-duration tumoral growth located in the upper lip was diagnosed on incisional biopsy as epithelial-myoepithelial carcinoma. After wide surgical excision the histopathological analysis revealed the lesion was composed predominantly (>90%) of adenoid cystic carcinoma. In new sections it was found a very small and isolated area of adenoid cystic carcinoma at the bottom of the incisional biopsy. As surgical margins were free of lesion, no adjuvant treatment was given. The occurrence of a transitory ischaemic attack at 36 months of follow-up led to a neurological and MRI evaluation, which disclosed a well-defined 3.5 x 3 cm lesion suggestive of metastasis, located on the right temporal area. The lesion was surgically removed and a histopathological diagnosis of neurocysticercosis was rendered. After 40 months of follow-up there is no evidence of recurrence. True hybrid tumors of salivary glands are rare and treatment in each case should be done according to the component with the higher aggressiveness. However, the occurrence of epithelial-myoepithelial carcinoma areas within an adenoid cystic carcinoma seems to be a frequent finding, and because both lesions share a common origin, some authors consider that this may not be a true hybrid neoplasm but a variant of the latter.

    Sclerosing mucoepidermoid carcinoma with eosinophilia is a rare morphological variant of thyroid carcinoma associated with Hashimoto's disease. To date, only three such tumors have been reported in the minor salivary glands. We describe the first case, to the best of our knowledge, of recurrent sclerosing mucoepidermoid carcinoma with eosinophilia in the minor salivary glands of the upper lip. A 61-year-old Japanese man was referred to our hospital with a mass in his median upper lip of four years' duration. An examination of his median upper lip revealed a well-defined tumor measuring 9 × 12 mm in diameter, which was subsequently resected. Three years after the first surgery, the tumor recurred and was resected. Both tumors were confirmed by histopathology to be sclerosing mucoepidermoid carcinoma with eosinophilia. Neither recurrence nor metastasis was observed in three and a half years of follow-up after the second surgery. Our findings indicate that sclerosing mucoepidermoid carcinoma with eosinophilia can originate in the minor salivary glands and may be clinically or pathologically misdiagnosed as other conditions.

    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

    NUT midline carcinoma is a rare and aggressive tumor that has primarily been reported in children and young adults. The tumor is characterized by a rearrangement on the nuclear protein in testis (NUT) gene, located on chromosome 15q14, resulting in the BRD4-NUT fusion oncogene. This carcinoma most commonly presents in the midline and displays an invariably lethal clinical course. To highlight the imaging features of NUT midline carcinoma. IRB approval was obtained for chart review. We retrospectively reviewed the chart and imaging studies of three children. All three cases were diagnosed by karyotyping and confirmed by fluorescence in situ hybridization (FISH). Cross-sectional imaging including CT, MRI and, in one patient, PET was available for review. Two out of three children presented with midline and multifocal disease. The third case had a medial left thigh mass and no metastatic disease at initial presentation. The common imaging features include heterogeneous low density on CT and T1 hypointensity and low-level T2 hyperintensity on MRI with heterogeneous enhancement. All cases were confirmed pathologically and by molecular studies. NUT midline carcinoma usually presents in the midline, either in the head, neck or chest. We present three cases with the bulk of the tumor below the diaphragm, which is seen in the minority of patients with NUT midline carcinoma, according to the available literature. Metastatic disease is common at initial presentation and can be quite extensive. The most striking feature of this disease is its aggressive nature with exponential interval growth of tumor.

    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

    Background: Small-cell carcinoma (SCC) and large-cell neuroendocrine carcinoma (LCNEC) are uncommon in serous body cavity effusions. The purpose of this study is to examine the cytomorphological spectrum of SCC and LCNEC in body cavity serous fluids. Materials and Methods: We have 68 cases from 53 patients who had metastatic SCC or LCNEC diagnoses. All cytology slides and the available clinical data, histological follow-up, and ancillary studies were reviewed. Results: A total of 68 cases (60 pleural, 5 peritoneal, and 3 pericardial effusions) from 53 patients with an average age of 73 years (age range 43-92 years) were reported as diagnostic or suspicious of SCC (52 cases) or LCNEC (16 cases). The primary site was lung in 56 cases, pancreas in 6 cases, and 2 cases each from cervix, colon, and the head and neck region. Of the 68 cases, 48 cases had no history of malignancy of the same type. Ancillary studies were used in 46 cases (68%) including flow cytometric studies in 5 cases. There were three predominant cytomorphological patterns observed including small-cell clusters with prominent nuclear molding (33 cases, 49%), large-cell clusters mimicking non-small-cell carcinoma (18 cases, 26%), and single-cell pattern mimicking lymphoma (17 cases, 25%). Significant apoptosis was seen in 22 cases (33%) and marked tumor cell cannibalism was seen in 11 cases (16%). Nucleoli were prominent in 16 cases (24%). The most frequent neuroendocrine markers performed were synaptophysin and chromogranin. Conclusions: The most common cytomorphologic patterns seen in body cavity effusions of SCC and LCNEC were small-cell clusters with nuclear molding. However, in 51% of the cases either a predominant single-cell pattern mimicking lymphoma or large-cell clusters mimicking non-small carcinoma were noted. In our experience, effusions were the first manifestation of disease in the majority of patients diagnosed with neuroendocrine carcinoma. Therefore, familiarity with the

    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.

    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

    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.

    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.

We report two cases of VHL disease with bilateral renal cell carcinoma. Case 1: A 53-year-old woman was referred to our hospital because of bilateral kidney tumor incidentally found. We performed left laparoscopic radical nephrectomy and laparoscopic nephrectomy, ex vivo excision and reconstruction, and autotransplantation for the right kidney. Case 2: A 43-year-old woman was referred to our hospital because of left kidney tumor incidentally found. Because the suspectious lesion in the right kidney was very small, we decided to follow it up with no treatment. We performed laparoscopic nephrectomy, ex vivo excision and reconstruction, and autotransplantation for left kidney.

    The authors present a study of 83 cases of sclerodermiform basal cell carcinoma. This series constitutes 2.3% of all skin cancers treated in the authors' unit from 1981 to 1996. The predominant site of these carcinomas is the centrofacial region with 46% of tumours involving the nose. In the majority of cases, treatment consisted of cover by a flap (52.6% of cases). Full-thickness skin grafts were used in 29% of cases and excision-suture was performed in 18.4% of cases. The authors emphasize the need to perform large resection with safety margins determined by the macroscopically visible tumour diameter. As frozen section pathological examination is not contributive, they prefer to defer reconstruction until the final pathology results are obtained. The only exception is the need to cover a vital region, such as the eye. These carcinomas must be followed in the long-term, as 20% of recurrences were detected in this series, comprising many orbitopalpebral sites, associated with difficult staging, and which always have a reserved prognosis. The authors therefore propose the use of epitheses in so-called high-risk sites. The three main guidelines in this disease, one of the most worrying forms of skin cancer, are surgical aggressiveness, modesty in terms of the cosmetic result and alertness in the follow-up.

    Micropapillary carcinoma (MPC) is a rare aggressive tumor, which generally accompanies the primary carcinoma of the organ of its origin, while the pure form is extremely uncommon. Angiolymphatic involvement is widespread and a considerable proportion of the cases present with metastases. The current study presents eight pure MPC cases arising from the breast (n=3), urinary bladder (n=3), parotid gland (n=1) and lung (n=1, presenting with pericardial effusion), with the cytological findings. The eight patients included three female and five male cases aged between 48 and 74 years. The most common cytological findings were three-dimensional aggregates, cell clusters with angulated or scalloped borders, single cells with a columnar configuration and eccentric nuclei, and high-grade nuclear features. Histopathological sections showed accompanying in situ ductal carcinoma in the cases of MPC arising in the parotid gland and breast (n=3), and one case in the bladder exhibited only in situ MPC. The average follow-up period was 20 months (range, 6–54 months) and, during this period, three patients succumbed to the disease. At present, four patients are alive with disease and one patient is alive and disease-free. In conclusion, cytology is an important tool for the diagnosis and management of MPC. PMID:25013488

    Papillary thyroid carcinoma (PTC) is a rare childhood disease. The development of PTC in dyshormonogenetic congenital hypothyroidism (CH) is infrequent, with very few case reports in literature. To report a case of PTC in a boy with dyshormonogenetic CH without goitre and exposed to ionising radiation. To evaluate relationships between these factors and development of PTC. We present a boy with dyshormonogenetic CH since birth. Early hormonal substitution was initiated, with subsequent normal levels of thyrotropin and thyroid hormones. He has also congenital cardiomyopathy, exposed to interventional treatment with 10 heart catheterisations, and approximately 26 chest X-rays at paediatric doses. A thyroid nodule was found in thyroid echography at the age of 6 years old. Fine needle aspiration biopsy confirmed high probability of thyroid carcinoma (Bethesda 5). The pre-surgical thorax and cerebral scan showed no evidence of metastasis. The patient underwent total thyroidectomy. Pathological examination revealed a 0.5cm papillary thyroid micro-carcinoma in the right lobe, with no evidence of dissemination. Genetic mutations and radiation exposure may play an important role in the development of PTC. There may be common pathways between dyshormonogenetic CH and thyroid carcinoma that need further investigation. Copyright © 2016 Sociedad Chilena de Pediatría. Publicado por Elsevier España, S.L.U.

    Undifferentiated gastric carcinoma is a rare histopathological type of cancer that does not show any differentiation toward adenocarcinoma or squamous cell carcinoma. It is thought to be highly malignant, and is associated with a poor prognosis. However, its clinical behavior has not yet been fully analyzed because of its rarity. We herein review the clinical characteristics and prognoses of patients with undifferentiated gastric carcinoma treated at our institutions. Among 2,651 gastric cancer patients, four (0.2 %) were histopathologically diagnosed to have undifferentiated carcinoma. These four patients included three males and one female. The median age of the patients was 60-year old (range 47-75). Three cases had distant metastases at diagnosis. One of these three cases was treated with chemotherapy alone, and the other two were treated with palliative gastrectomy and chemotherapy. The patient with no distant metastasis underwent curative gastrectomy and adjuvant chemotherapy. All patients died of cancer at a median of 5.4 (range 3.5-7.1) months after their diagnoses.

    Few reports of mucinous cystic neoplasm (MCN) in association with anaplastic carcinoma exist. The present study reported an unusual case of a 25-year-old female exhibiting large pancreatic MCN with anaplastic carcinoma. Notably, the patient was a Jehovah's Witness and therefore refused any blood transfusions. Preoperative diagnosis was invasive pancreatic MCN measuring 12.5 cm with ascites. Distal pancreatectomy was performed in combination with splenectomy and partial resection of the transverse colon. Intraoperative estimated blood loss was 400 ml, therefore a blood transfusion was not required. The patient had an uneventful postoperative course. The pathological diagnosis was mucinous cystadenocarcinoma of the pancreas with anaplastic carcinoma. Although the patient underwent postoperative adjuvant chemotherapy with gemcitabine and oral fluoropyrimidine (S-1), recurrence with peritoneal dissemination was detected 20 months following surgery and the patient succumbed to the recurrence 32 months following surgery. To the best of our knowledge, this is the first case report of MCN with anaplastic carcinoma of the pancreas in a Jehovah's Witness patient undergoing pancreatic surgery.

    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. Copyright © 2013 Elsevier España, S.L. and SEMNIM. All rights reserved.

    Primary signet cell carcinoma of the cervix has been reported only in 18 cases to date. A 48-year-old woman was seen at our Gynecologic Oncology Unit, because she complained postcoital bleeding during the last three months. She had 1-2 cm cervical mass, originating from the endocervical canal. A biopsy revealed a signet ring cell-type adenocarcinoma. Suspected primary sites were excluded after gastroscopy, colonoscopy and mammography. The patient underwent a laparoscopic type-3 radical hysterectomy with bilateral salpingo-oophorectomy, pelvic lymph node dissection and paraaortic lymph node dissection with a presumed diagnosis of primary signet ring cell carcinoma of the cervix. Microscopically, the tumour consisted of 70% signet ring cell type and 30% endocervical adenocarcinoma. She did not receive any adjuvant treatment. Follow-up at 18 months after surgery showed no evidence of recurrence. Nineteenth case of a primary signet ring cell carcinoma of the cervix was presented. Immunohistochemical studies and HPV DNA positivity may help in diagnosis. It is crucial to differentiate primary tumour from metastatic signet cell carcinoma, while treatment and prognosis differ significantly. Copyright © 2016 The Authors. Published by Elsevier Ltd..

    Neuroendocrine neoplasms of the gall bladder (GB) are rare tumors classified as grade 1 and 2 neuroendocrine tumor (NET), neuroendocrine carcinoma (large cell or small cell type), and mixed adeno-neuroendocrine carcinoma (MANEC). Primary neuroendocrine carcinomas (NEC) of GB are rare with grave prognosis not withstanding radical surgical treatment. Chemotherapy forms the primary management due to the advanced stage at presentation, as complete surgical resection is generally not possible. The overall median survival is 4-6 months despite aggressive management. Only 73 cases of small cell carcinoma (SCC) and 10 cases of large cell neuroendocrine carcinoma (LCNEC) have been reported in English literature till now. We present a series of 19 cases of NEC of GB with their pathological and clinical features and response to treatment. The objective of this study was to evaluate NECs of the GB for their clinical behavior, prognosis, and treatment outcome in terms of survival and to segregate NECs into further subcategories, that is 20-50 % and >50 %, based on MIB-1 index. We retrospectively searched the clinical and pathological database over 2.5 years (January 2012 to June 2014) through existing electronic hospital medical records to collect cases of NEC arising in GB. A total of 447 cases of gall bladder pathologies were analyzed, of which 19 cases were diagnosed as NEC. All relevant investigations were documented and response to treatment/therapy was evaluated clinically and radiologically. Tumor specimen was obtained by fine-needle aspiration cytology and/or biopsy and classified using the latest World Health Organisation (WHO) classification (2010) via cytopathologic, histopathologic, and immunohistochemical visage. Nineteen patients diagnosed as NEC of GB were evaluated in the study, with 16 having SCC, 2 having LCNEC, and 1 with MANEC. All patients presented in advanced clinical stage III or IV, along with distant metastasis and showed progressive disease during

    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.

    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.

    The incidence of extrahepatic bile duct malignancies is about 2-3.6% of all gastrointestinal malignancies. Primary carcinoma of cystic duct is a rare condition comprising a fraction of all extrahepatic bile duct malignancies with less than 70 cases reported worldwide. Majority of these cases were reported from East Asia. There is paucity in such case being reported from Indian subcontinent. We present a case of primary carcinoma of the cystic duct encountered during laparoscopic cholecystectomy. A 65-year-old lady presented to us with symptomatic gall stone disease. Investigations revealed a distended gall bladder with multiple stones. Patient was taken up for laparoscopic cholecystectomy, during surgery a stony hard structure was found at cystic duct-common bile duct junction which was not amenable for clear dissection. Procedure was converted to open, and the patient underwent cholecystectomy with resection of common bile duct with Roux-en-Y hepaticojejunostomy and regional lymphadenectomy. Histopathological findings revealed it to be moderately differentiated adenocarcinoma of the cystic duct. Primary carcinoma of cystic duct is a rare condition where early diagnosis can be difficult and if accidentally detected may add to surgeon's dilemma. Proper surgery with en-bloc resection of gallbladder, cystic duct, common bile duct, and regional lymphadenectomy is the mainstay of treatment. The prognosis of carcinoma of cystic duct is better than extrahepatic bile duct malignancies. The old classification system has outlived its time and is more rigid in definition which is not practical in advanced cases; the new classification systems of this century offer better insight into understanding the tumor characteristics and prognosis.

    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.

    Previous descriptive studies have suggested an increased risk of testicular carcinoma in military aviators. The association between testicular carcinoma and aviation in the U.S. Air Force was measured using a case-control study design. A Department of Defense hospitalization database was used to obtain a set of testicular carcinoma cases (seminomas, embryonal cell carcinomas, teratocarcinomas, and choriocarcinomas) and an unmatched set of male appendicitis controls from October 1988 to February 1999. A centralized U.S. Air Force personnel database was used to obtain demographic and flying history data on the subjects. Multiple logistic regression was used to obtain odds ratios (OR) and confidence intervals (CI) for the following exposure factors: total flight time, rank, crew position, and general type of aircraft. Study subjects were restricted to white active duty officers. For one or more total flight hours, the age-adjusted OR was 1.74 (95% CI 1.04-2.92). Age-adjusted OR's for 1-499, 500-1999, and 2000 or more flight hours were, respectively, 1.37, 1.92, and 1.67. These OR's were not statistically significant. Age- and flight hour-adjusted OR's were increased for the navigator crew position and for bomber/tanker/ transport/reconnaissance type aircraft (2.13 and 1.67, respectively), but the ratios were not statistically significant. OR's were not increased for senior rank, fighter/trainer type aircraft, and rotary-wing aircraft. There is an association between testicular carcinoma and flight time in U.S. Air Force officers. There was a suggestion of a dose-response effect; however, the OR's were not statistically significant.

    Longstanding renal calculus is a risk factor of squamous cell carcinoma (SCC) of the renal pelvis. It is highly aggressive and usually diagnosed at advanced stages with a poor prognosis. We present two cases of kidney stone complications with renal pelvic SCC. These two patients had a radical nephrectomy and the dissected tissues were renal pelvic SCC. Our cases further emphasize that renal pelvic SCC should be considered in patients with longstanding renal calculus. These cases contribute greatly to an early diagnosis and early treatment, both of which will significantly minimize the damage of, and markedly improve the prognosis of, renal pelvic SCC.

    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.

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.

    Poorly Differentiated Thyroid Carcinoma (PDTC), especially advanced PDTC, is an aggressive disease and displays a much poorer prognosis compared with well differentiated thyroid carcinoma. Surgery is the recommended treatment in the early stage of PDTC, however, no effective treatment modalities are currently available for advanced PDTCMethods: Two advanced PDTC patients with no radioiodine uptake adopted a cytotoxic chemotherapy with liposomal doxorubicin (35 mg/m(2), day 1) plus cisplatin (75 mg/m(2), day1-3) every 3 weeks. Computer tomography (CT) was performed after 6 cycles (case 1) or 5 cycles (case 2) of chemotherapy Our patients achieved remarkable response with one a Complete Remission (CR) and the other a very good Partial Remission (PR)Conclusion: Our findings indicate that liposomal doxorubicin-based chemotherapy regimens might produce response in PDTC patients, and improve their overall survival and quality of life. Hence we believe this result is very important for oncologists in treating PDTC.

    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

    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.

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.

    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.

    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.

    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

    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

    Neuroendocrine neoplasms are defined as epithelial neoplasms with predominant neuroendocrine differentiation. They can arise in almost every organ of the body although they are most commonly found in the gastrointestinal tract and respiratory system. Nasal cavity and paranasal sinuses are a rare site for neuroendocrine carcinoma. In contrast to the other regions, neuroendocrine tumours of the sinuses have been reported to be recurrent and locally destructive. Very few cases of paranasal sinus neuroendocrine carcinoma have been reported till date. Difficulty in pathologic diagnosis and rarity of this malignancy have hindered the progress in understanding the clinical course and improving outcomes. We herein report a case of poorly differentiated neuroendocrine tumour of ethmoid and sphenoid sinus with invasion of orbit and intracranial extension. The patient had complete response at the end of chemoradiation and he was disease-free for 9 months duration after which he developed bone metastasis without regional recurrence. PMID:23476846

    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.

    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.

    Myoepithelial carcinoma (MEC) is a rare salivary gland tumor. Its long-term prognosis remains unknown because of the paucity of reported cases with long-term follow-up. Although some case series exist, the clinical features of MEC vary considerably depending on the site of origin. Therefore, accumulation of these rare cases is important. Case 1: An 89-year-old man presented with a 10-year history of a mass originating from the right parotid gland and involving the neck. The mass grew rapidly for 3 months, reaching approximately 8 cm. There was no facial paralysis. MEC ex pleomorphic adenoma (PA) was suspected. Superficial parotid gland resection was performed in 2013; the tumor grade was pT3N0M0, and the resection margins were free of carcinoma. Because of several high-risk factors for metastasis (i.e., invasive carcinoma ex PA, high MIB1 index, and mutant p53 protein positivity), radiotherapy and chemotherapy were recommended as adjuvant therapy. Although the patient refused adjuvant therapy, he was recurrence-free at 36 months after surgery. Case 2: A 54-year-old woman presented with a >10-year history of a right submandibular mass, which grew rapidly for 1 year, reaching approximately 6 cm. Preoperative diagnosis was PA of the right submandibular gland. Submandibular gland resection was performed in 2013. Pathological analysis revealed invasive MEC ex PA, pT3N0M0; in addition, the carcinoma portion had an extra capsule and had invaded the platysma muscle close to the margin. An MIB1 index of 40 % and mutant p53 protein positivity indicated a high risk for metastasis. Additional resection and right neck dissection revealed no residual carcinoma. The patient refused adjuvant chemotherapy. One year after surgery, metastasis to the right pulmonary hilar node and both lungs were detected. Chemotherapy prevented recurrent growth of the lesion and extended survival. The patient was alive with cancer 30 months after the first surgery. High expression of the Ki67

    Carcinosarcoma (CS) of breast is a rare disease. Published reports provided little consensus about its clinical characteristics and optimal treatment protocols. Here we present a patient with CS of breast (mucinous carcinoma and malignant fibrous histiocytoma) and review related literature. Combined modality treatment (CMT) brings at least 2 year disease-free survival (DFS). Our case highlights the possibility of breast CS and helps to expand our understanding of this distinct breast malignancy.

    Malignant tumors with extragenital origins are rare in cervicovaginal samples. A case of metastatic lobular carcinoma of the breast was diagnosed in a cervicovaginal smear. Histologic correlation was performed. Marker studies for carcinoembryonic antigen, human milk fat globule membrane, epidermal growth factor receptor, epithelial membrane antigen and cytokeratin were positive. Recognition of extrauterine cancer in the cervicovaginal smear has important diagnostic, prognostic, and therapeutic implications.

    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.

    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. 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. 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%). 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.

    Thyroid cancer and Graves' disease may present simultaneously in one patient. The incidence of the development of hyperthyroidism from metastatic differentiated thyroid carcinoma is rare. We herein report a case of metastatic follicular carcinoma complicated with Graves' disease after total thyroidectomy. A 57-year-old woman underwent right hemithyroidectomy for follicular carcinoma. Metastatic lesions appeared in the lungs and skull two years after the first surgery, and remnant thyroidectomy was performed for radioactive iodine-131 (RAI) therapy, during which the TSH receptor antibody (TRAb) was found to be negative. The patient was treated with RAI therapy four times for four years and was receiving levothyroxine suppressive therapy. Although radioiodine uptake was observed in the lesions after the fourth course of RAI therapy, metastatic lesions had progressed. Four years after the second surgery, she had heart palpitations and tremors. Laboratory data revealed hyperthyroidism and positive TRAb. She was diagnosed with Graves' disease and received a fifth course of RAI therapy. 131I scintigraphy after RAI therapy showed strong radioiodine uptake in the metastatic lesions. As a result, the sizes and numbers of metastatic lesions decreased, and thyroid function improved. Metastatic lesions produced thyroid hormone and caused hyperthyroidism. RAI therapy was effective for Graves' disease and thyroid carcinoma.

    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.

    Cutaneous metastasis from neuroendocrine carcinomas of visceral origin is rarely described in indexed literature. The primary sites of origin include: lung (Wick et al., J Am Acad Dermatol 1985; 13: 134), larynx (Zambruno et al., Ann Dermatol Venereol 1989; 116: 855; Schmidt et al., J Laryngol Otol 1994; 108: 272; Guerzider et al., Ann Pathol 1991; 11 (4): 253), mediastinum (Yoshimasu et al., J Dermatol 2001; 28 (3): 168), uterus (Fogaca et al., J Cutan Pathol 1993; 20: 455), and thymus (Wick et al., J Am Acad Dermatol 1985; 13: 134). In this report, the authors present the clinical, histological, immunohistochemical, and ultrastructural characteristics of secondary skin localizations of a neuroendocrine laryngeal tumor that occurred in a 61-year-old man. The complete follow up of the case is described and a brief revision of the terminology and classification of neuroendocrine neoplasms of the larynx is discussed, since a significant relationship exists between the degree of differentiation and biological behavior. On histological examination, the secondary cutaneous localization appeared to be more dedifferentiated compared to the primary tumor. The immunohistochemical patterns of reactivity were similar in both neoplasms, showing expression of neuroendocrine and epithelial markers. An important issue of prognostic significance is to differentiate a cutaneous metastasis of a neuroendocrine carcinoma from the primary small cell-undifferentiated carcinoma of the skin (Merkel cell carcinoma).

    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

    1991-03-01

    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.

    2015-01-01

    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 identify the clinical and radiologic features of nevoid basal cell carcinoma syndrome (NBCCS) in the Hong Kong Chinese, particularly those of keratocystic odontogenic tumors (KCOTs), at first presentation at a dental hospital. A consecutive case series of NBCCS was identified in the University of Hong Kong Dental Hospital. All 5 Hong Kong NBCCS cases presented with symptoms arising from their KCOTs; 3 with swelling, 3 with pain, and 2 with nasal discharge. The cases exhibited 4 major features (KCOTs, calcified falx cerebri, palmar/plantar pits, and basal cell carcinoma) and 4 minor features (sella bridges, bossing, hypertelorism, and mandibular prognathism). The KCOTs were all unilocular. The tumors displaced teeth in 4 cases. Only 1 had root resorption. There were 2 nonsyndromic cases with multiple KCOTs. The unilocular presentation of the syndromic KCOTs was significantly greater than that of the solitary cases, arising within the same community over the same period. The other presenting features of the syndromic KCOTs did not differ from the solitary KCOTs. The recurrence rate of syndromic KCOTs was significantly greater than of the solitary KCOTs. Nonsyndromic cases with multiple KCOTs could be more common in East Asians. Copyright © 2015 Elsevier Inc. All rights reserved.

    To report the diagnosis and treatment experience of pediatric gastric cancer. Clinicopathological data of a girl with gastric carcinoma in December 2011 was analyzed retrospectively. The literatures were reviewed. The disease onset, clinical manifestations, treatment, and prognosis of the patient with gastric carcinoma were studied. The patient was a 12-year-old girl, and the tumor was located in greater curvature. The girl underwent laparoscopy-assisted radical total gastrectomy (D2). Pathological examination showed gastric ulcerative signet-ring cell cancer (pT4N0M0, stage II b). The outcome at the recent follow up was satisfactory. Literature review demonstrated 15 cases of pediatric gastric carcinoma, of whom 7 were boys and 8 girls. Their average age was 12.7 years (2.5-17.8 years). Tumor locations included cardia (n=5), gastric body (n=1), gastric antrum or stomach corner (n=4), gastric antrum and gastric body (n=1), and unknown (n=4). Histology showed signet-ring cell cancer in 4 patients, poorly differentiated in 6, moderate to poorly differentiated and moderate differentiated adenocarcinoma in 2. Operation was performed in 11 cases and perioperative chemotherapy in 8 cases. Nine patients had follow-up. Four patients died within 6 months and other 4 patients survived for 6 months to one year. The survival time of one patient who underwent radical surgery and perioperative chemotherapy was 102 months. Pediatric gastric carcinoma is extremely rare. It is highly malignant and associated with poor prognosis. Radical surgery is the most important treatment. Perioperative chemotherapy may improve the prognosis.

    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

    Red dot basal cell carcinoma is a unique variant of basal cell carcinoma. Including the three patients described in this report, red dot basal cell carcinoma has only been described in seven individuals. This paper describes the features of two males and one female with red dot basal cell carcinoma and reviews the characteristics of other patients with this clinical subtype of basal cell carcinoma. A 70-year-old male developed a pearly-colored papule with a red dot in the center on his nasal tip. A 71-year-old male developed a red dot surrounded by a flesh-colored papule on his left nostril. Lastly, a 74-year-old female developed a red dot within an area of erythema on her left mid back. Biopsy of the lesions all showed nodular and/or superficial basal cell carcinoma. Correlation of the clinical presentation and pathology established the diagnosis of red dot basal cell carcinoma. The tumors were treated by excision using the Mohs surgical technique. Pubmed was searched with the keyword: basal, cell, cancer, carcinoma, dot, red, and skin. The papers generated by the search and their references were reviewed. Red dot basal cell carcinoma has been described in three females and two males; the gender was not reported in two patients. The tumor was located on the nose (five patients), back (one patient) and thigh (one patient). Cancer presented as a solitary small red macule or papule; often, the carcinoma was surrounded by erythema or a flesh-colored papule. Although basal cell carcinomas usually do not blanch after a glass microscope slide is pressed against them, the red dot basal cell carcinoma blanched after diascopy in two of the patients, resulting in a delay of diagnosis in one of these individuals. Dermoscopy may be a useful non-invasive modality for evaluating skin lesions when the diagnosis of red dot basal cell carcinoma is considered.

    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

    Clear cell carcinoma (CCC) is a rare, low-grade malignant neoplasm of minor salivary glands. Clear cell carcinoma is composed of monomorphic clear cells that contain glycogen within a hyalinized stroma. The microscopic diagnosis can be challenging, and the treatment strategy has not been established. We report a case of a 56-year-old woman with CCC in the base of the tongue. A literature review, including 22 published cases and our case, was performed to clarify the clinical characteristics of CCC in the base of the tongue. The exophytic tumor showed no infiltration to the neighboring tissues. She underwent a local excision en bloc transorally and is free of the disease 15 months after surgery. In our review of 23 cases of CCC in the base of the tongue, 21 cases received surgical excision for the purpose of the primary treatment modality. The fact that the distinctive features of restricted site-related symptoms and the rare presentation of pain emerged was similar to previously reported cases of CCC. A relatively good prognosis was still indicated. We reveal the features of the unusual occurrence of CCC in the base of the tongue and consider the appropriate surgical approach for primary treatment. © The Author(s) 2014.

    Endocrine mucin-producing sweat gland carcinoma (EMPS) is a rare low-grade sweat gland carcinoma with an infiltrating growth pattern. It occurs mostly in women and shows a predilection for the periorbital region. Histopathologically, the tumor shows analogous features to endocrine ductal carcinoma/solid papillary carcinoma of the breast and shares some clinical and morphological similarities with primary mucinous carcinoma of the skin. The tumor is characterized by large monomorphous epithelial cells with little nuclear pleomorphism and only a few mitotic figures. The solid cystic tumor shows mucin-filled small cystic spaces, cribriform areas and expresses the neuroendocrine markers synaptophysin, chromogranin and neuron-specific enolase with varying staining intensities. The tumor cells are also positive for estrogen and progesterone receptors. We present three cases of this rare tumor with typical clinical, histopathological and immunohistochemical findings, give a short summary of the literature and discuss the most relevant differential diagnoses.

    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

    Background The occurrence of calcitonin-secreting primary carcinoid tumor of the urinary bladder is extremely rare. Case presentation The case of a 68-year-old male with carcinoid tumor arising in the urinary bladder is presented. Transurethral resection of a polypoid small tumor 0.4 cm in diameter was performed. Immunohistochemical study using neuroendocrine markers allowed a straightforward diagnosis of a low-grade neuroendocrine carcinoma (carcinoid tumor) of the urinary bladder. Immunohistochemistry demonstrated calcitonin immunoreactivity in the most of the tumor cells. Conclusion This tumor shows specific clinical, macroscopical and histological features and must be considered in the differential diagnosis of bladder neoplasms. PMID:16048646

    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

    Generalized morphea is a rare idiopathic form of scleroderma that literally means "hard skin." Morphea is usually considered an isolated event that is not associated with malignancy. However, case reports of lung, hematologic, and breast cancer occurring simultaneously with large plaque morphea have caused dermatologists to question whether a work-up for malignancy is appropriate. We highlight a case of generalized morphea that preceded invasive ductal carcinoma of the breast and provide a discussion about the possible paraneoplastic origin of generalized morphea and systemic sclerosis (SSc).

    Primary pituitary gland cancer is extremely rare. The current study presents the case of a patient diagnosed with pituitary cancer three months after completing surgery and post-operative chemoradiotherapy for hypopharyngeal cancer. In this report we discuss 57-year-old patient who presented with diplopia and ptosis four months following the completion of treatment for hypopharyngeal cancer. A poorly-differentiated pituitary carcinoma was located. Despite aggressive treatment and surgical excision with postoperative chemoradiotherapy, the disease progressed rapidly and the patient succumbed due to multiple metastases and organ failure. This case report indicates a possible correlation between irradiation and the development of pituitary cancer.

    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.

    The trichilemmal carcinoma is a rare malignant neoplasm, whose origin lies in the annexes of the skin, because of its low prevalence often confused with other dermal tumors, the differential diagnosis is not easy and is usually made by exclusion; in theory, its behavior is slow with little tendency to send both regional lymph node metastasis and systemic. Due to the limited number of cases there is no consensus on the prognosis, although it is generally considered good. The aim of this report is to show a case that, contrary to previous reports, the clinical presentation is aggressive with large soft tissue tumor infiltration around the site of origin in a patient without risk factors for skin cancer. Male patient, 65 years old with cytologic diagnosis of carcinoma in a preprarotideal facial tumor, characteristics at diagnosis were infiltration of the facial skin, ear, and parotid gland. Complete block resection was performed, radical parotiroidectomy and radical neck dissection; the soft tissue defect was covered with a pediculated flap. The evolution was satisfactory it follow-up short though. We evaluated the experience in the literature regarding the prognosis and treatment of these patients. Trichilemmal carcinoma can be fully invasive behavior prognosis is difficult to know and probably depends on the clinical stage at diagnosis.

    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.

    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.

    Verrucous carcinoma of the esophagus is a variant of a squamous cell cancer. Our case is a 78-year-old male patient comes in with the dysphagia and weight loss, and on endoscopy (EGD) he is found to have an irregular intraluminal mass at the distal esophagus. With the deep EGD assisted biopsy, diagnosis of the verrucous carcinoma is made. Due to multiple co morbidities and possible infiltration to the pericardium, patient is taken for the esophageal stent placement and is being referred for the chemo-radiation treatment. The diagnosis can be very difficult to make with the superficial biopsies due to very non specific histological changes and requires very high clinical suspicion and deep mucosal biopsies are required for accurate diagnosis of the tumor. Chronic and local disease process is the main risk factor for the development of the verrucous carcinoma of the esophagus. Surgery is the treatment of the choice for the early stage tumor and advanced cases are treated with the palliation and possibly chemo- radiation. The prognosis is usually guarded and needs long term follow up.

    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.

    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.

    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 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.

    Basaloid squamous carcinoma (BSC) of the esophagus is a rare esophageal tumor. A 79-year-old man with a history of proximal gastrectomy for gastric adenocarcinoma in 2000 was followed-up by esophagogastroduodenoscopy (EGD) annually. In June 2010, EGD revealed a new protruding lesion in the cervical esophagus. The small lesion was approximately 5 mm in size. A biopsy specimen showed poorly differentiated squamous cell carcinoma. We performed endoscopic mucosal resection using a cap-fitted endoscope (EMRC). The histological diagnosis of the endoscopically resected specimen was BSC and the invasion depth was limited to the muscularis mucosae. Horizontal and vertical margins were negative. We report the case of superficial BSC in the cervical esophagus successfully resected by EMRC.
