    Multiple primary bronchogenic carcinomas (MPBCa) are extremely rare. The differentiation of a MPBCa from a pulmonary metastasis due to an extrathoracic neoplasm is sometimes difficult. We reviewed 324 pathologically proved primary pulmonary carcinomas and found six cases of MPBCa (1.9%). We herewith present the series and discuss the diagnosis of MPBCa. PMID:21594435

    Interleukin-10 (IL-10) is a recently characterized cytokine with suppressive activity against various aspects of the cellular immune response. Our laboratory has previously demonstrated that another anti-inflammatory cytokine, IL-1 receptor antagonist (IRAP) is produced and secreted by human bronchogenic carcinomas. We speculated that tumor production of IRAP may mitigate host responses and confer increased tumor viability. In this study, we investigated the capacity of human bronchogenic tumors to produce IL-10 as another possible mechanism to attenuate host defenses. We found increased levels of antigenic IL-10 in tissue homogenates of human bronchogenic carcinomas compared with normal lung tissue (13.69 +/- 2.87 versus 5.84 +/- 0.84 ng/mg total protein). Immunohistochemical staining of tumors illustrate primary localization of antigenic IL-10 to individual tumor cells. Analysis of supernatants of several unstimulated human bronchogenic cell lines in vitro demonstrated the ability of tumor cells to constitutively produce IL-10. Functional studies of mononuclear cells, cultured in the presence of conditioned medium from a bronchogenic cell line, demonstrated their increased tumor necrosis factor and IL-6 production with the addition of neutralizing antibodies to IL-10. These findings demonstrate that human bronchogenic carcinomas elaborate functional IL-10, which may significantly impair immune effector cell function and enable the tumor to evade host defenses.

  4. The clinical management of bronchogenic carcinoma-- A progress report.

    A number of new concepts in the clinical management of bronchogenic carcinoma have been introduced since an original review of this problem in The Johns Hopkins Medical Journal in 1967. Four specific problems in the updated management of patients with bronchogenic carcinoma are discussed: 1) the patient with cytologic evidence of malignant cells in the sputum and a normal chest radiograph; 2) the patient with an asymptomatic peripheral pulmonary nodule; 3) the patient with symptomatic bronchogenic carcinoma or bronchogenic carcinoma in a lobar or main stem bronchus; 4) the assessment of operability. Tantalum bronchography and fiberoptic bronchoscopy have proven effective in localizing the source of malignant cells shed from a radiologically occult bronchogenic carcinoma. Percutaneous needle biopsy and transbronchial biopsy under fluoroscopic control permit pathological examination of peripheral nodules. Transcervical mediastinoscopy and left parasternal exploration, as well as increased use of angiography and more sophisticated pulmonary function tests, allow better determination of the resectability of central lesions. As a result, fewer patients are subjected to unnecessary thoracotomies, and if thoracotomy is undertaken it usually offers the patient a reasonable chance of cure. PMID:1185914

    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.

    Cardiac metastases in bronchogenic carcinoma may occur due to retrograde lymphatic spread or by hematogenous dissemination of tumour cells, but direct invasion of heart by adjacent malignant lung mass is very uncommon. Pericardium is frequently involved in direct cardiac invasion by adjacent lung cancer. Pericardial effusion, pericarditis, and tamponade are common and life threatening presentation in such cases. But direct invasion of myocardium and endocardium is very uncommon. Left atrial endocardium is most commonly involved in such cases due to anatomical contiguity with pulmonary hilum through pulmonary veins, and in most cases left atrial involvement is asymptomatic. But myocardial compression and invasion by adjacent lung mass may result in myocardial ischemia and may present with retrosternal, oppressive chest pain which clinically may simulate with the acute myocardial infarction (AMI). As a result, it leads to misdiagnosis and delayed diagnosis of lung cancer. Here we report a case of non-small-cell carcinoma of right lung which was presented with asymptomatic invasion in left atrium and retrosternal chest pain simulating AMI due to myocardial compression by adjacent lung mass, in a seventy-four-year-old male smoker.

    OBJECTIVE: To better understand the characteristic morphology of angiogenic squamous dysplasia (ASD) and its association with different types of common bronchogenic carcinomas using routine white light bronchoscopy. METHODS: Using a case-control design, 186 formalin-fixed paraffin-embedded blocks of bronchial tissue (136 cases, 50 controls) obtained from patients who underwent routine nonfluorescence bronchoscopy between 2004 and 2005 were studied. RESULTS: ASD occurred at a higher frequency in patients with neoplastic lesions compared with those without neoplastic lesions (28 of 136 versus one of 50). ASD was also more prevalent in patients with squamous cell carcinoma compared with other neoplasms. Seventy six per cent of the ASD patients (22 of 29) smoked cigarettes. The morphology of ASD on hematoxylin and eosin- and CD31-stained sections was characterized by prominent microvasculature and capillary projections closely juxtaposed to variable degrees of dysplasia in all of the bronchogenic carcinoma specimens, and to metaplasia in one case in the control group. CONCLUSION: ASD is a unique morphological entity that should be considered by pathologists even on bronchoscopic biopsies from patients who undergo white light bronchoscopy. The presence of ASD may represent a risk biomarker of bronchogenic carcinoma in screening programs and in chemoprevention of lung cancer. PMID:22679613

    To evaluate the usefulness of transbronchial needle aspiration biopsy (TBNA) for the diagnosis of mediastinal involvement, we have prospectively examined 316 patients with morphologically verified bronchogenic carcinoma. The percentage of positive aspirations (149 of 316) from the three basic lymph node groups in the mediastinum was not significantly different. Tumor cells were aspirated from the mediastinum in 75 of 112 patients with radiologically positive findings and in patients with 74 of 204 radiologically negative findings. Mediastinal involvement was verified even in 61 of 196 patients with a normal endoscopic picture. Metastases were proved in 14 of 39 patients with peripheral versus 135 of 277 patients with central carcinoma. Tumor cells were aspirated in 47 of 76 patients with undifferentiated small cell carcinoma, 92 of 227 patients with squamous cell carcinoma, and 10 of 13 patients with adenocarcinoma. Our results suggest that TBNA being a highly diagnostic and less invasive method, will prove its clinical importance. PMID:18493418

    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.

    All cases of bronchogenic carcinoma treated with curative intent over an eight-year period were reviewed. Most were treated with 12 x 400 rad in 32 days using /sup 60/Co, a schedule designed to optimize the radiation-sensitizing properties of hyperbaric oxygen. While O/sub 2/ gave no obvious benefit, overall four-year survival was 10.6% and that of patients with good prognostic indicators was 18%. No radiation myelitis was observed. This protocol delivers an adequate tumor dose and appears to be tolerated well by most patients.

    One hundred and forty-three patients with unresectable non-small cell bronchogenic carcinoma were treated with combination chemotherapy consisting of cyclophosphamide, doxorubicin, and cisplatin (CAP). Objective responses were seen in 27.5% of 131 evaluable patients. Response rates for squamous cell carcinoma, adenocarcinoma, and large cell anaplastic carcinoma were 30.2% (13 of 43 patients), 28.0% (14 of 50), and 32.1% (nine of 28), respectively. The median survival time for responders with extensive disease was 33.0 weeks compared with 29.3 weeks for patients with stable disease and only 9.6 weeks for patients with disease progression. The survival advantage of patients responding to CAP relative to those who had disease progression during treatment is highly significant statistically (P = 0.0005). However, patients whose disease remained stable also had longer survival than those who had disease progression (P = 0.001), and their survival was not significantly different from that of responders (P = 0.19). The CAP chemotherapy regimen was generally well-tolerated, although acute gastrointestinal symptoms were common. Our results indicate that CAP chemotherapy can cause tumor regression in patients with non-small cell bronchogenic carcinoma and may extend the survival of responding patients. PMID:7028256

    A heteroantiserum raised in rabbits to extracts of human squamous-cell carcinoma of the lung which exhibited marked tumour specificity was used to monitor the fractionation and isolation of a tumour-associated component of the extract. KC1 extracts of pools of both normal lung and bronchogenic squamous-cell carcinoma were subjected to a series of purification steps involving acid precipitation, salting out, DEAE chromatography and preparative polyacrylamide-gel electrophoresis. At each stage, fractions were tested for their ability to react in the complement-fixation assay with the antiserum. A protein was ultimately isolated which did not appear to be present at detectable levels in an equivalent fraction of normal lung extract, reacted with the heteroantiserum, and appeared to be present in all extracts of squamous-cell carcinoma.

    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.

    The addition of methotrexate to a previously described regimen of cyclophosphamide, Adriamycin (doxorubicin), and high-dose vincristine (VAC) was tested in 50 evaluable patients with small cell bronchogenic carcinoma. Prophylactic whole brain radiation therapy was given during the first chemotherapy course and consolidation radiation therapy was given to the mediastinum and primary site after achieving partial or complete remission. The addition of methotrexate did not improve the incidence of complete remission as compared to a previous regimen without it. The addition of radiation therapy improved the local control rate. The high-dose vincristine in this and a previous CAV study improved the incidence of complete remission in both limited and extensive disease presentation as compared with the authors previous experience and induced an acceptable and reversible neurotoxicity. Moderate dose consolidation radiotherapy to the lung primary and mediastinum was effective in improving local control. The distinction between limited and extensive disease was found to be vague, as 22% of the patients could be shifted from one group to the other depending on definition. The evaluation of the various staging procedures indicates that bone scan gave a small number of truly abnormal tests. Isotopic brain and liver-spleen scan could be duplicated by computerized axial tomography (CAT). CAT scan of abdomen disclosed unexpected extension to the retroperitoneal nodes and adrenals.

    Between June 1980 and December 1983, 111 patients with inoperable epidermoid bronchogenic carcinoma (limited disease) were entered into a randomized trial comparing radiotherapy alone versus radiotherapy and combination chemotherapy with cyclophosphamide, Adriamycin (doxorubicin), methotrexate, and procarbazine. Thirty-five of 62 (56.4%) patients treated with 4500 rad in 15 fractions in 3 weeks and 19 of 49 (38.8%) patients treated with the same radiation treatment and chemotherapy had an objective response. The difference in response rate was not significant (P = 0.900). Median time to progression was 5.9 and 7.02 months, respectively, for the radiation treatment and the combined treatment. Median survival was 11.74 and 10.03 months, respectively, without statistically significant differences between the two groups of patients. The toxicity was acceptable and no treatment-related death occurred in either treatment schedule. In this study no significant superiority of combined radiotherapy and chemotherapy treatment over radiation therapy alone was evidenced. Whether different chemotherapy regimens may prove more effective in this context should be clarified by further studies.

    While endobronchial lesions that present with symptoms of obstruction may be reflective of primary bronchogenic malignancy, there have been a number of reports of bronchial lesions other than primary bronchogenic carcinoma simulating primary endobronchial epithelial malignancy clinically. Twenty-five cases of symptomatic endobronchial disease were encountered with pathological assessment demonstrating an endobronchial process other than carcinoma, representing metastatic disease (breast, colon, renal, head and neck origin), fungal infection, Hodgkin's lymphoma, primary bronchogenic melanoma, lipoma, broncholith and inflammatory pseudopolyp. The present report underscores the potential pathogenetic heterogeneity encountered in lesions presenting with signs and symptoms of endobronchial obstruction, emphasizing the critical role of biopsy for establishing a definitive diagnosis.

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

    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. PMID:27365560

    Over the past 30 years, there has been considerable controversy regarding the role of segmental and wedge resections in the management of stage I (T1-T2N0M0) non-small-cell lung cancer. Recently, a prospective randomized trial (Lung Cancer Study Group, 1995) revealed unfavorable results after limited resection, which, in early stage lung cancer, remains a reasonable option for patients with compromised pulmonary reserve, especially those in whom a previous contralateral resection has been performed. The following report describes the role of limited resection in the management of patients with T1-T2N0 non-small-cell lung cancer and presents a retrospective review of our series of 125 limited resections out of 1356 resections performed for lung cancer. In particular, long term survival and the frequency of local/regional recurrence were noted in 92 cases operated on with a curative intent. 26.6% vs 12.5% local/regional recurrence rates were observed among patients undergoing limited resections for T2 and T1 lung cancer, respectively. The five year survival in the limited resection group was 13.5% for T1 and 60% for T2 vs 51% and 72% in the standard procedure group, respectively. The lobectomy results were superior to those of sublobar resection. The latter should be reserved for patients in poor general condition contraindicating a standard lobectomy. PMID:10932366

    Abstract Esophageal bronchogenic cysts are extremely rare. Here we report a more rare type of both presence of intra- and paraesophageal bronchogenic cyst that was safely removed via surgical resection. A 31-year-old male patient with space-occupying lesions in the mediastinum suddenly presented with persistent chest pain for 2 days and then transferred to dysphagia >1 week. Preoperative diagnosis is difficult. Endoscopic ultrasonography (EUS) showed a hypoechoic cystic-solid mass arising from the muscularis propria and local hyperechoic area in the deeper portion of cyst, concomitant with a heterogeneous center and tube-like structure lesion in mediastinum. Turbid coffee color paste contents were aspirated inside the tumor under endoscopic ultrasonography guided-fine needle aspiration (EUS-FNA). A subsequent surgery was performed and histologic finding was diagnostic of esophageal bronchogenic cyst. Immunohistochemical staining confirmed the cyst was positive for carbohydrate antigen 199 (CA199) and carbohydrate antigen 125 (CA125). At a follow-up visit 3 months later, the patient had a regular diet and no complaint. This study is to summarize the clinical manifestations and EUS features of esophageal bronchogenic cyst by retrospectively reviewing the literature and simultaneously to provide guide for the correct examination scheme. The appearance of esophageal bronchogenic cyst can be great variation; EUS seems to be a valuable option for diagnosis and surveillance. PMID:26986156

    Bronchogenic cysts (BCs) are rare congenital cystic lesions arising as a development malformation in the trachea-bronchial system during the embryonic period. The cysts mostly occur in the mediastinum, with an extremely low morbidity rate in the oromaxillofacial-head and neck region. The age distribution of patients who present with BCs shows a significant predominance towards young individuals compared with the elderly. The current study reports the case a 70-year-old female who presented with a painful mass in the right cervical region. Pre-operative computed tomography (CT) and ultrasound showed a heterogeneous hypodense cystic lesion accompanied by infection. A mass of gaseous density was observed on repeat CT following antibiotic therapy. The pathological examination after complete resection revealed a BC, which can also be easily misdiagnosed as common congenital cervical cysts, such as a branchial cleft cyst or a thyroglossal duct cyst, among others. There was no recurrence or any discomfort during the 34-month follow-up period. PMID:26893692

    Ameloblastic carcinoma is a rare odontogenic tumor exhibiting not only features of ameloblastoma, but also features of carcinoma. Clinical dissemination of this lesion is more aggressive and rapid than that of ameloblastoma and it can metastasize to the lung or regional lymph node. Histologically, there are features of both ameloblastoma and carcinoma. <50 cases have been reported until 2011. We report a series of six cases with our treatment modalities. PMID:25210376

    Bronchogenic cyst (BC) is a rare congenital malformation of the lung. Most patients remain asymptomatic until adulthood while some are symptomatic in the first few years of life. However, symptoms in newborn period are rare. We report a case of a 3-day-old preterm baby with respiratory distress diagnosed as congenital lobar emphysema on chest X-ray. A CT scan revealed a mediastinal cyst causing obstructive lobar emphysema. The cyst was excised and pathological examination was suggestive of BC. PMID:27609589

    Bronchogenic cysts are congenital sacs that result from maldevelopment of the primitive foregut. Although they occur predominantly in the chest, there are reports of lesions in extrathoracic locations. The majority of reported bronchogenic cysts located in the neck are found in the pediatric population; a review of the literature reveals few reports of bronchogenic cysts of the neck among adults. The diagnosis of a bronchogenic cyst relies on the histology and location of the lesion. Here, we review our experience in the diagnosis and management of 2 adult patients with pathologically proven bronchogenic cysts. Both patients presented with solitary neck masses that proved to be bronchogenic cysts on histologic examination. Our purpose is to define the histopathologic and clinical characteristics of bronchogenic cysts and discuss the features that distinguish them from other cervical cysts. In conclusion, congenital bronchogenic cysts can occur in the neck of adults and should be considered in the differential diagnosis of cystic cervical masses in adults, as well as children.

    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. PMID:20498190

    This study investigates the relationship between exposure to radioactive Rn decay products during U mining and milling operations, cigarette smoking and age, on the incidence and mortality rates of lung cancer among U workers of the Colorado Plateau during the 20-yr period from 1960-1980. A case control sample was taken from an extensive data base of 9,817 men accumulated by one author (Saccomanno). A preliminary hypothesis had been made that a possible synergistic or at least additive effect might exist when the risk factors of exposure to Rn decay products and smoking were simultaneously present. This study would seem to indicate that a synergistic effect is not present. In this work, a total of 489 cases, defined as men having a cytological diagnosis of moderate or worse atypical squamous-cell metaplasia, and a random sample of 992 ''non-cases'' were selected retrospectively from the dynamic cohort of workers. These data analyzed from three different perspectives indicate significant effects due to Rn-decay-product exposure in excess of the expected incidence due to age and smoking history. The data also indicate that Rn-decay-product accumulations of less than 300 working level months (WLM) is not carcinogenic in non-cigarette 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.

A 21-year-old male was referred to our institution because of a cough, fever, and worsening of abnormalities on his chest radiograph, despite anti-tuberculosis treatment. Computed tomography of the chest showed a large multi-cystic mass over the right-upper lobe. Pathological examination of the excised lobe showed a bronchogenic cyst combined with a destructive cavitary lesion with granulomatous inflammation. Microbiological culture of sputum and lung tissue yielded Mycobacterium avium. The patient was administered anti-mycobacterial treatment that included clarithromycin. PMID:23346002

    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.

    Two hundred and thirty-one patients of advanced oesophageal carcinoma were treated with Neodymium: Yttrium-Aluminium-Garnet (Nd:YAG) laser photocoagulation of tumour tissue to relieve distressing dysphagia. There were 155 males (67.1%) and 76 females (32.9%). The mean age was 59.6 years. Eighty-five percent (196 cases) were above 50 years of age. Distribution of tumour by site was as follows: upper one-third--24 cases (10.4%), mid one-third--98 cases (42.4%) and lower one-third--109 cases (47.1%). Squamous cell carcinomas accounted for 83.5% (193) of cases. Nearly two-thirds (144 cases, 62.3%) were more than 4 cm in length. Tumour deposits were found at more than one site in 11 cases (4.7%). Oesophageal lumen was restored in all cases but was poorly sustained in 19 cases (8.2%). Further sessions of laser therapy were required in all these cases. A mean of 2.7 sessions of laser treatment was required to achieve adequate lumen. One hundred and eighty-nine patients (82%) had good relief of dysphagia to liquids and semi solids. Complications were seen in 20 cases (8.6%). There were no deaths related to the procedure. Mean survival was 5.5 months (1-14 months). Nd:YAG laser therapy offers effective palliation of dysphagia in carcinoma of the oesophagus with acceptable morbidity and no mortality. PMID:7514382

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

    A 41-year-old male visited with chief complaints of chest pain and cough. The patient was operated on under a diagnosis of invasive thymoma. The tumor was located in the left lobe of the thymus and measured 6 X 9 cm. Since the tumor invaded the left innominate vein, pericardium, and the upper lobe of the left lung, we resected it with adjacent structures. Postoperative pathological examination indicated squamous cell carcinoma of the thymus. Because the tumor metastasized also to the mediastinal lymph nodes, the patient was treated postoperatively by radiation therapy and adjuvant chemotherapy mainly with CDDP. The patient is well presently 2 years after operation without signs of recurrence. PMID:2212787

    Bronchogenic cysts are the most common cystic mediastinal lesion in children. Bronchogenic cyst causing unilateral obstructive emphysema is a rare presentation. We report the case of a one and half month old infant who presented with respiratory distress which was initially suspected as left pneumothorax on frontal chest radiograph but was later found to be due to hyperinflated left lung and hence the possibility of congenital lobar emphysema was considered. CT thorax and limited MRI sections revealed a cystic lesion in mediastinum causing obstructive emphysema and mediastinal displacement. He underwent an emergency thoracotomy and excision of the cyst via an extrapleural approach. Post operatively, rapid improvement of the infant was noticed both clinically as well as radiologically. Cross sectional imaging like CT or MR is required for reaching the correct and early diagnosis in paediatric patients with respiratory distress, when there is diagnostic dilemma based on chest radiograph.

    Bronchogenic cysts arise from abnormal budding of the ventral diverticulum of the foregut or tracheobronchial tree during embryogenesis, are the most common cystic masses in the mediastinum, and are generally asymptomatic. A spontaneous regression in a mediastinal bronchogenic cyst (MBC) with pneumonia is rare. A 30-year-old male had a tumor shadow in the middle mediastinum. When he visited our hospital, he had a mild fever with coughing and sputum. A chest computed tomography (CT) scan showed a decrease in the tumor size and the existence of right pneumonia. MBC may be involved in the etiology of pneumonia; therefore, bronchogenic cysts need to be resected as soon as possible. PMID:26943430

    Introduction Intracystic papillary carcinoma represents a small distinctive subgroup of noninvasive breast cancer, accounts for <0.5% of breast malignancies and is extremely rare in men, it was originally reported as a localized non-invasive carcinoma, but is usually associated with ductal carcinoma in situ around the main tumor or invasive carcinoma. Case presentation We report a case of 50-year-old man with intracystic papillary carcinoma in man with ductal carcinoma in situ who underwent a tumorectomy following by a radical Patey intervention (Halsted). Conclusion Nowadays, there is still no clear consensus regarding optimal treatment of intracystic papillary carcinoma. Most papers reinforce the importance of an adequate surgical margin in conservative treatment. Surgeons must pay much attention to the potential for ductal carcinoma in situ around the tumor when selecting the operative procedure. PMID:19829939

    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

    Microglandular adenosis (MGA) is a rare benign disease that shows an infiltrative growth pattern of small glands, and it may progress to include atypia and carcinoma. Here we report two cases of breast carcinoma arising in MGA. Case 1 was a 44-year-old woman with a previous history of ductal carcinoma in situ in her right breast. During a follow-up, a 1.8 cm mass-like lesion was found in her left breast. An excisional biopsy suggested that the lesion was breast carcinoma. Case 2 was a 57-year-old woman with a 2.9 cm mass in her right breast. A core needle biopsy of the lesion suggested invasive carcinoma. Both patients underwent modified radical mastectomy with sentinel lymph node biopsy. Both tumors lacked a myoepithelial cell layer and stained positively for S-100, lysozyme, and α1-antitrypsin, which is typical of MGA. Both cases showed invasive carcinoma arising in MGA.

    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.

    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. PMID:26589365

    Penile cancer is an extremely rare form of urological cancer that usually originates in the epithelium of the inner preputium or glans. Major etiological factors include phimosis, poor penile hygiene and smoking. Nearly 95% of penile cancers are squamous cell carcinomas and usually occur in the sixth decade of life. The disease exhibits two variants, namely metastatic and atypical disease. Squamous differentiation may also present with mucinous metaplasia. An extremely limited number of case reports on penile cancer are available in the literature. The present study reports the case of a 39-year-old patient with penile mucinous adenocarcinoma who was admitted with the complaint of perineal discharge, which is, to the best of our knowledge, the first case in the literature. The patient underwent total penectomy and inguinal lymph node dissection. The tumor was staged as T4N1M0, according to the European Association of Urology’s tumor-node-metastasis classification system. The patient was treated with pelvic radiotherapy and six cycles of systemic neoadjuvant chemotherapy with cisplatin and paclitaxel simultaneously, over a period of four months. After nine months of follow-up the patient succumbed to the disease due to widespread metastases. PMID:25663900

    Trichilemmal carcinoma is a cutaneous adnexal tumor originating from the outer root sheath of hair follicle, and it was first described by Headington in 1976. Clinically, it usually occurs as an asymptomatic solitary papule, nodule or mass on the face or scalp. This neoplasm is a malignant counterpart of trichilemmoma, and it has been reported in the literature as trichilemmal carcinoma, tricholemmal carcinoma, malignant trichilemmoma, and tricholemmocarcinoma. Although histologically, trichilemmal carcinoma frequently has maliganant features, it has a relatively benign clinical behavior. We think Mohs micrographic surgery is a useful treatment modality in trichilemmal carcinoma because the final skin defect is smaller than a wide excision. We report a case of primary trichilemmal carcinoma which had developed on the face, treated with Mohs micrographic surgery. PMID:27303183

    Mucoepidermoid carcinoma (MEC) of the lungs is a rare type of lung cancer, mainly arising from the submucosal salivary type mucous glands of the large bronchi. MEC is classified into low- and high-grade subtypes based on its cytological and histological features, and this classification correlates well with prognosis. We report the case of a 36-year-old man diagnosed after an initial episode of obstructive pneumonia. CT and bronchoscopy revealed an endobronchial mass in the right S3 bronchus and distal atelectasis. Although biopsy is important for deciding the treatment plan, both pre- and intraoperative biopsy resulted in false negativity in this patient. The tumor was completely resected via right upper lobectomy, and the final pathological diagnosis was low-grade MEC. No evidence of disease was found 2 years after the operation without any adjuvant therapy. At (11; 19) translocation with the associated CRTC1-MAML2 fusion oncogene is often recognized in cases of both salivary and pulmonary MEC. It is speculated that MEC is sensitive to EGFR-TKI therapy, which disrupts CRTC1-MAML2-induced proliferation signals via upregulation of the EGFR ligand amphiregulin. PMID:26805187

We present a case of an 85-year-old male patient with a giant ulcerating tumor of the left forehead (measuring 7x6 cm). Under local anesthesia tumor was surgically excised. No involvement of the underlying periostal or bone structure was noted. Pathohystological exam revealed the giant basal cell carcinoma, with free surgical margins. Giant basal cell carcinomas are rare tumors and are usually result of a long duration and patient neglect. In comparison to the ordinary basal cell carcinoma these tumors have a higher metastatic potential. Surgical resection with negative surgical margin is the best possible treatment option.

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

    A 6-year-old Malay boy presented with fever and abdominal pain for 2 months. Computerised tomography showed a nodular mass in the left lobe of the liver. There was also portal vein thrombosis on the left side. Serum alpha-fetoprotein was not elevated and Hepatitis B antigen was negative. Biopsy of the liver mass led to a histological diagnosis of fibrolamellar hepatocellular carcinoma. In view of extensive tumour involvement, he could not be operated on but was treated with chemotherapy. However, the tumour did not respond. While this is expected for fibrolamellar hepatocellular carcinoma, the possibility of the tumour having a component of ordinary hepatocellular carcinoma could not be excluded as the tumour was not resected. Fibrolamellar hepatocellular carcinoma is a rare histological subtype of hepatocellular carcinoma, associated with a better prognosis. It affects the younger age group and has no association with cirrhosis, hepatitis B virus infection or exposure to oral contraceptives, all of which are implicated in ordinary hepatocellular carcinoma. Serum alpha-fetoprotein level is usually within normal limits and other laboratory values are not contributory to the diagnosis. The diagnosis is usually suggested by radiographic studies viz. CT scan of the abdomen, which would show an irregular non-homogenous mass in the liver, and confirmed by histological examination. The most characteristic microscopical feature is fibrosis arranged in a lamellar fashion around polygonal and deeply eosinophilic neoplastic hepatocytes. PMID:12166592

    Endometrial cancer is the most common gynecologic malignancy in developed countries. Clear cell carcinoma typically occurs in the ovaries, and very rarely occurs in the endometrium; it accounts for less than 3% of all endometrial cancers. It is presumed that clear cell carcinomas are of Müllerian duct origin, and an association with exposure to diethylstilbestrol (DES) or other nonsteroidal follicle stimulating hormones has been described. We report a case of a postmenopausal woman who presented with vaginal bleeding without a specific medical history. Under the impression of an endometrial mass, we performed a laparoscopic operation. Pathologic results showed clear cell carcinoma of the endometrium. Depth of invasion was 0.2 cm out of a 0.5 cm total thickness, and the rectal shelf mass was clear cell carcinoma. We report the case with a brief review of the relevant literature. PMID:27617248

    Small cell carcinoma of bladder, which does not have a common and accepted treatment protocol, is a rare and highly aggressive tumor. It is mostly pulmonary originated; however, it can rarely be seen in extrapulmonary sites. We presented an interesting and uncommon case, in which the transitional cell tumor was found in the transurethral resection specimen, but the small cell carcinoma was detected in the final radical cystectomy material.

    The purpose of this case presentation is to alert the clinician and pathologist to the unique features of verrucous carcinoma. Although the nasopharynx is an unusual site for this tumor, the features inherent to verrucous carcinoma are apparent; a misleadingly benign histologic appearance which contrasts dramatically with the inexorable progressive destruction of normal structures. Secondary infection is common and should not be mistaken for a primary process. Diagnosis rests on dialogue between clinician and pathologist. PMID:7359618

    Adenosquamous carcinoma (ASC) and sarcomatoid carcinoma (SC) of the prostate are rare, but highly aggressive tumors. The occurrence of mixed carcinomas in the prostate is even more rarely reported. The present study reports the case of a 62-year-old male who was diagnosed with prostatic adenocarcinoma accompanied by multiple bone metastases, as shown by a needle biopsy and skeletal computed tomography scan. The patient was treated with hormonal therapy, but thereafter, specimens from a transurethral resection of the prostate (TURP) were found to be composed of three histologically distinct elements: ASC, SC and adenocarcinoma. The level of p53 was evaluated by immunohistochemistry in detail, and it was found that this was significantly increased in the TURP samples compared with the needle biopsy samples. The abnormal level of p53 was likely associated with the prognosis of the patient; the patient succumbed to prostate carcinoma two months after the confirmation of the diagnosis. PMID:25295118

    Patient: Male, 67 Final Diagnosis: Gastric cancer with neuroendocrine carcinoma Symptoms: — Medication: — Clinical Procedure: Total gastrectomy • splenectomy with D2 lymph node dissection Specialty: Surgery Objective: Rare co-existance of disease or pathology Background: Many neuroendocrine carcinomas exhibit medullary infiltration and expanded proliferation. Differentiated tubular adenocarcinoma is frequently seen in the superficial region in many neuroendocrine carcinoma cases. However, the present case showed non-medullary infiltration and signet ring cell carcinoma in the superficial region, with intramural metastases distributed throughout the whole of the stomach. Case Report: A 67-year-old man was referred to our institution for treatment of gastric cancer. Type IIc-like advanced gastric cancer was detected in the greater curvature of the middle body of the stomach. The patient underwent total gastrectomy, splenectomy with D2 lymph node dissection, and Roux-en-Y reconstruction with curative resection. The tumor was diagnosed as a large-cell endocrine carcinoma of the stomach. A solid growth of signet ring cells was seen in the mucosa and submucosa. Intramural metastases were observed in many other depressed lesions. Large-cell carcinoma invaded the submucosa, mainly in the intramural metastatic site. Metastasis to one lesser curvature lymph node was also seen on histological examination. The final diagnosis was a gastric cancer of type 0–IIc (T4a) [M] (with intramural metastases) at T4aN1H0P0M0 Stage IIIA. This patient has remained alive without recurrence for 72 months after surgery. Conclusions: We recommend close preoperative examination of neuroendocrine carcinoma, taking intramural metastases into consideration. PMID:27102318

    Histiocytoid breast carcinoma (HBC) is a rare type of breast cancer with a controversial histogenesis. Here we describe a case report of a 65-year old woman with HBC. The patient presented with two masses in the right breast. Histopathologically, the tumors consisted of a diffuse infiltration of large tumor cells and histological components of carcinoma in situ and atypical lobular hyperplasia were also observed. The infiltration pattern was similar to that of invasive lobular carcinoma with targetoid and Indian file arrangements. The invasive histiocytoid cells had finely granular, eosinophilic to vesicular cytoplasm and nuclei with a bland uniform appearance, a single small eosinophilic nucleolus and finely granular chromatin. We compared the immunohistochemical profiles of 17 breast cancer markers between invasive carcinoma, carcinoma in situ, atypical lobular hyperplasia and normal breast epithelium. Although they all shared the same reactivity for many of the proteins, they exhibited differences in GCDFP-15, E-cadherin, P120, CEA, HER-2, ER and PR expression, and these are discussed. This is the first case study of two HBC masses occurring in one breast simultaneously. By analyzing and comparing their morphologic characteristics and spectrum of immunohistochemical expression, our study supports the view that HBC is a variant of lobular carcinoma and our findings may assist in future diagnoses of HBC.

The patient reported in this case is a 59-year-old man who suffered from headache and delirium for 4 days after surgical treatment for removal of a bladder carcinoma 1 year ago. Magnetic resonance imaging (MRI) revealed a solid tumor involving the pineal gland with significant enhancement. The patient underwent surgical treatment for removal of the neoplastic lesion in the pineal gland. Histopathological examination confirmed invasion of the pineal gland by metastatic urothelial carcinoma. This case highlighted that the presence of pineal lesions in patient with known malignancy should raise suspicion of metastatic involvement. PMID:27149501

    Dermatomyositis (DM) is an inflammatory disease of unknown origin that manifests as a myopathy associated with typical skin lesions. Association between DM and cancer is frequent (from 18% to 32% according to case series). It was described for the first time by Stertz in 1916 in association with gastric cancer. All histological types and sites of cancer in the general population may be associated with DM. Its association with nasopharyngeal carcinoma (NPC) is rarely described and the incidence proportion is 1 case of nasopharyngeal carcinoma per 1.000 persons. PMID:27583093

    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. PMID:26851989

    Several targetable genetic alterations have been found in lung cancer, predominantly in adenocarcinomas, which have led to important therapeutic advancements with the advent of targeted therapy. In contrast, the molecular features and presence of targetable genetic abnormalities in pulmonary sarcomatoid carcinomas are largely unknown. Thirty-three cases of pulmonary sarcomatoid carcinoma were tested for approximately 2800 mutations in 50 oncogenes and tumor-suppressor genes, including EGFR, KRAS, NRAS, TP53, BRAF, ERBB2, JAK3, AKT1, ATM, MET, KIT, and PIK3CA. ALK immunostaining was performed, and ALK FISH was performed on cases with any degree of staining. Twenty-four of the 33 cases (72%) had at least one genetic abnormality: 19 cases (58%) had TP53 mutations; 10 cases (30%) had KRAS mutations; AKT1, JAK3, BRAF, NRAS, and PIK3CA mutations were observed in 1 case each (3%). Six of the 19 cases (32%) with a mutation in TP53 had simultaneous mutations in KRAS (18%). The cases with alterations in JAK3, BRAF, and NRAS also had mutations in TP53. The case showing a mutation in PIK3CA had a mutation in KRAS. No EGFR mutations were observed. One case had ALK gene rearrangement. ALK rearrangement was observed in a single case of sarcomatoid carcinoma (3%), which has currently available targeted therapy. Four tumors had mutations in genes with experimental molecular-based therapy, including BRAF, NRAS, PIK3CA, and AKT1. Testing for targetable mutations should be considered for patients with pulmonary sarcomatoid carcinoma, as a subset may benefit from currently approved drugs or clinical trials of novel therapeutic options available for other types of lung cancer.

    Trichoepitheliomas (TE) are benign tumours but occasionally can undergo transformation to malignant neoplasms more commonly as Basal Cell Carcinoma (BCC). The correct diagnosis between these tumours is very important because basal cell carcinoma is locally aggressive neoplasm and requires total surgical excision with wide healthy margins while trichoepithelioma needs simple excision. We describe three patients who developed basal cell carcinoma with facial trichoepitheliomas. The only clinical feature that distinguished the carcinomas from the trichoepitheliomas was their larger size, in all three patients, one patient with recurrent, hyper pigmented swelling with surface ulceration and in another patient there are multiple trichoepitheliomas, and other family members are also affected. The history, clinical features and histopathological findings were suggestive of the evolution of basal cell carcinoma directly from trichoepithelioma in our first two cases, but in the third case TE and BCC were separate lesions on face and we are uncertain about whether the BCC developed independently or by transformation from a trichoepithelioma. Based on our clinicopathological observations in the three patients and reports in the recent literature, BCC with follicular differentiation and trichoepithelioma are considered to be highly related.

    The occurrence of primary carcinoma of the ureteral stump following radical nephrectomy for renal cell carcinoma is extremely rare; 7 patients with the disease have been reported previously. All these patients were males with transitional cell carcinoma. The current study reports the case of a 61-year-old woman, who presented with gross hematuria following a radical nephrectomy for local clear cell renal carcinoma. A computed tomography scan revealed the presence of a mass on the ureteral stump. The patient underwent a left ureteral stump and bladder cuff excision. The histological diagnosis was high-grade transitional cell carcinoma of the ureteral stump, with focal interstitial cancer cell infiltrates. There was no evidence of recurrence during a follow-up period of 35 months. In addition, the present study reviewed the literature for previous patients with ureteral stump carcinoma following a radical nephrectomy for renal cell carcinoma; 7 previous patients with the disease were identified. The present study suggests that, if patients who have previously undergone a radical nephrectomy for renal cell carcinoma present with hematuria, the possibility of ureteral stump carcinoma should be considered, particularly in East Asian countries. The existence or a history of bladder carcinoma should be considered as a high-risk factor for developing ureteral stump carcinoma. A ureteral stump and bladder cuff excision should be performed once ureteral stump carcinoma is diagnosed. PMID:27123110

    The macrofollicular variant of papillary thyroid carcinoma (MFPTC) is a well-established entity with characteristic large follicles containing pale colloid and lined by cells with nuclear features of papillary thyroid carcinoma (PTC). In this study, we present three cases of MFPTC, along with a brief review of the literature. For all three of our cases, the histology of the resected specimen showed predominantly macrofollicular structures lined by cells with nuclear characteristics of PTC. Immunohistochemically, the three cases show positivity for galactin-3, cytokeratin-19, and HBME-1. These cases will help us in understanding the distinction from other benign and malignant follicular lesions of the thyroid, which is of utmost importance. The key to diagnosis is a high-power examination of any macrofollicular lesion of the thyroid. PMID:22048513

    Silent pituitary corticotroph carcinomas are rare, with only six previously described cases in the literature. We report a patient with a silent pituitary corticotroph adenoma treated with multiple trans-sphenoidal resections. Twelve years after her initial presentation, she returned with leptomeningeal metastases to the posterior fossa, foramen magnum, and numerous other subarachnoid locations involving the spine. Histopathology obtained from the metastatic foci was identical to previous trans-sphenoidal specimens - consistent with the diagnosis of corticotroph pituitary carcinoma. A carboplatin and etoposide chemotherapy regimen successfully arrested disease progression and produced regression of multiple radiographically documented leptomeningeal deposits. To the authors' knowledge, this is the first report of a patient with silent pituitary carcinoma treated successfully with chemotherapy. PMID:27150544

    Secretory carcinoma is a unique kind of adenocarcinoma. It has distinct histological features and a special genetic change, that is, t (12; 15) (p13; q25) translocation which leads to the expression of the ETV6-NTRK3 fusion gene. Secretory carcinoma has been found to occur both in the breast and salivary gland. Here the authors present a case of 22-year-old woman with a unique cutaneous neoplasm located at the axilla. The tumor was characterized histologically with the formation of round to ovoid microcysts and papillary structure, which was similar to the secretory carcinoma of the breast and salivary gland. Furthermore, the gene sequence analysis of reverse-transcription polymerase chain reaction products demonstrated the expression of the ETV6-NTRK3 fusion gene. To the authors' knowledge, this is the first case of secretory carcinoma from the skin which has the same genetic change as those from the breast and salivary gland. Local excision was performed on this patient. She had been followed up for nearly 1 year. No recurrence or metastasis was found yet. PMID:26981741

    The 5 cases of salivary duct carcinoma (SDC); very rare, but distinct group of highly malignant salivary gland tumor are presented, and difficulties with pathological and clinical diagnosis is discussed. The SDC developed in single cases in parotid salivary gland, submandibular salivary and in mucosa of maxillary sinus, pyriform fossa and oral cavity (check). In 3 cases the second malignant tumor was present--synchronously (SDC + pleomorphic adenoma in parotid gland; SDC + squamous cell carcinoma in hypopharynx) or metachroneously (squamous cell carcinoma of upper lip followed by SDC). In one case the high levels of PSA suggesting of metastases from unknown primary within the prostate gland, or PSA expression related to SDC was observed. The four patients received radical treatment - surgical resection followed by radiotherapy; in one case only palliative treatment was applied, due to patient's poor general condition and high advancement of the primary disease. The observation ranged from 10 to 77 months (average time--31 months). The one patient died 13 months after diagnosis and palliative treatment. The three patients are alive with distant metastases to the lung and bones (77, 38 and 18 months after primary treatment was completed). Only one patient with 10 months observation after treatment is living without symptoms of recurrence or metastases. PMID:17605416

    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 = .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

    Endometrial cancer is the most common malignancy of the female reproductive system. The three common spread patterns of endometrial cancer are local invasion, lymphatic spread and hematogenous spread. Vaginal metastasis occurs by submucosal lymphatic or vascular metastases in ~10% of patients with clinical stage I disease. Vaginal implantation metastasis of endometrial cancer is extremely rare. Here we present a case of endometrial carcinoma (International Federation of Gynecology and Obstetrics stage IA) spread to the vagina by implantation metastasis as opposed to any of the methods mentioned above. This conclusion was confirmed mainly from pathological examination. This case highlights the occurrence of vaginal implantation metastasis of endometrial carcinoma. Certain changes may be applied during surgery to prevent implantation metastasis in patients with endometrial cancer. PMID:27347173

    Keratoacanthoma is variously regarded as a benign epithelial tumor, characterized by a rapid-growing and solitary flesh-colored nodule with a central keratin plug on the sun-exposed skin. Under certain circumstances, it can transform into squamous cell carcinoma. In this paper, we present a case of a 50-year-old man with a 2.5 × 3 × 2.2 cm mass on his penis stub-end. The patient was treat with a partial penectomy after further expert discussions and histopathology the lesion demonstrated penis keratoacanthoma. He received a partial penectomy again and the pathological result revealed squamous cell carcinoma this time. This case indicates that undergoing a partial penectomy on initial diagnosis of a penile tumor secondary to penile keratoacanthoma should be considered because of its high malignant potency. To our best knowledge, this is the first study to describe the malignant conversion of penis keratoacanthoma. PMID:26885065

    Basal cell carcinoma of the penis is an extremely rare entity, accounting for less than 0.03% of all basal cell carcinomas. Fortunately, wide local excision of such lesions is generally curative. Fewer than 25 cases have been reported in the literature describing penile basal cell carcinoma. Here we report a case of penile basal cell carcinoma cured with wide local excision. PMID:25298901

    Inguinal hernia and colonic carcinoma are common surgical conditions, yet carcinoma of the colon occurring within an inguinal hernia sac is rare. Of 25 reported cases, only one was a perforated sigmoid colon carcinoma in an inguinal hernia. We report two cases of sigmoid colon carcinoma, one of which had locally perforated. Each presented within a strangulated inguinal hernia. Oncologically correct surgery in these patients presents a technical challenge. PMID:18798013

    We report a case of dermatomyositis associated with prostatic carcinoma. A 69-year-old male was admitted to the Department of Internal Medicine with the chief complaint of general fatigue, appetite loss and facial anthema. Abdominal ultrasound demonstrated swollen periaortic lymph nodes and the margin of prostate was unclear. Prostatic carcinoma was suspected based on digital rectal examination, so he was admitted to our department. Serum prostate specific antigen level was 190 ng/ml. He was examined by a dermatologist because of deterioration of anthema. Dermatomyocitis was demonstrated by dermatoses (edema erythema at face, neck and limbs, nail fold thrombosis and poikiloderma), high serum level of creatine phosphokinase and a decrease in muscular strength (especially at the proximal musculus). There was no interstitial pneumonitis or malignancy of the digestive system. On needle biopsy of the prostate and quadriceps femoris muscle, prostatic carcinoma (poorly differentiated adenocarcinoma, Gleason score 5 + 5) and myositis were suspected. The stage of prostatic carcinoma was T4N1M1. The patient was treated by administration of diethylstilbestrol phosphate and prednisolone for prostatic carcinoma and dermatomyositis, respectively, but he died of multiple metastasis of the tumor 1 year and 5 months later. Dermatomyocitis is associated with malignancy more frequently than any other collagen disease. In Japan, it is frequently complicated by gastric, lung and mammory cancers, but rarely by prostatic carcinoma. To our knowledge, this is the fourth case of prostatic carcinoma associated with dermatomyocitis in Japan. PMID:15101164

    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.

    Mixed adenoneuroendocrine carcinoma (MANEC) is a rare tumor of the gastrointestinal tract that consists of a dual adenocarcinomatous and neuroendocrine differentiation, each component representing at least 30% of the tumor. To date, only seven cases have been reported in the cecum, and less than 40 in the stomach. Our first case was diagnosed in a 74-years-old female as a polypoid lesion of the cecum with direct invasion in the transverse colon, without lymph node metastases. The second case was diagnosed in the stomach of a 46-years-old male as a polypoid tumor of the antral region that invaded the pancreas and presented metastases in 22 regional lymph nodes. The metastatic tissue was represented by the glandular component. In both cases, the tumor consisted of a moderately-differentiated tubular adenocarcinoma (with mucinous component in Case 1) intermingled with neuroendocrine carcinoma. Ki67 index was lower than 20% in Case 1, respectively higher than 20% in Case 2. The neuroendocrine component was marked by synaptophysin and neuron specific enolase, being negative for Keratins 7/20. The neuroendocrine component represented 60% in Case 1, and 40% in Case 2, respectively. The glandular components were marked by carcinoembryonic antigen, maspin and keratin 20/7 (Case 1/2). Both cases were proved to be microsatellite stable. Independently by the localization and tumor stage, MANECs appear to be highly malignant tumors, with high risk for distant metastases. The aggressiveness seems to depend on the endocrine component, independent of its proportion. The neuroendocrine component could be a dedifferentiated adenocarcinoma with a neuroendocrine phenotype.

    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. PMID:25731343

    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.

    Occult thyroid carcinoma is very common in the clinic and is generally divided into four groups. Here, we proposed two types of occult thyroid carcinoma as the fifth group. The first type was locoregional lymph node metastases from thyroid carcinoma, and the second type was distant organ metastases from thyroid carcinoma. The unique aspect of the fifth group was that the primary carcinoma of the fifth group was not finally found by pathological examination. To better understand the fifth group, we reported a typical case. Furthermore, we discussed the diagnostic criteria and procedures and the management of the fifth group of occult thyroid carcinoma.

    Familial clustering of Hepatocellular Carcinoma (HCC) is commonly observed in various parts of the world including China and Eastern Asia where HBV is endemic while in western world, genetic factors and metabolic disorders may play an important role. In India, HCC is considered to be a rare tumour and till date no case of familial HCC has been reported here. Therefore the present case demonstrates rare occurrence of familial HCC which is being reported for the first time from India on cytology. The case also highlights an unusual feature that it was not associated with any risk factor including HBV, HCV infection, alcoholism, obesity, diabetes or smoking suggesting its independent association with genetic factors. Cytology is uncomplicated diagnostic tool for HCC and may be useful for its early diagnosis. This case also highlights the importance of early surveillance and follow up of blood relatives for every case of HCC so that early diagnosis and management of familial HCC is possible.

    Renal cell carcinoma (RCC) is well known for its frequent metastasis and particularly to the lungs, liver, bones and brain, but metastasis to the skin is rare. We report here on a case of metastatic RCC in a 73-year-old man who presented with a 1.5 cm sized, moist, beefy-red and exophytic nodule on the scalp. The lesion had grown rapidly for 2 months and it clinically mimicked granuloma pyogenicum. A skin biopsy revealed a solid mass composed of clear cells with clear cytoplasm and oval hyperchromatic nuclei, and they were arranged in an alveolar pattern. As skin metastasis from renal cell carcinoma signals widespread systemic metastasis and a poor prognosis, clinicians should conduct a careful inspection of the skin of a patient with RCC and they should also have a high index of suspicion for finding a primary internal organ malignancy in the RCC patients who present with a skin lesion.

    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. PMID:22969299

    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

    Neuroendocrine carcinoma (NEC) of the gallbladder is a rare subtype of gallbladder tumor. Here, we report two cases of NEC in two patients initially suspected to have gallbladder carcinoma. No specific symptoms or abnormal blood test results were observed preoperatively. Abdominal computed tomography scans indicated intraluminal masses in the gallbladder and lymph node enlargement in the hepatic hilum. Radical cholecystectomy and regional lymphadenectomy were performed. The first patient also presented with liver invasion and therefore underwent resection of liver segment IV. A diagnosis of NEC was made upon postoperative pathological examination and immunohistochemical staining according to the WHO Classification of Tumors of the Digestive System (2010). One tumor was identified as poorly differentiated NEC and the other as poorly differentiated mixed adenoneuroendocrine carcinoma. Immunohistochemical staining data from both tumors showed positivity for chromogranin A and synaptophysin. The first patient received 4 cycles of chemotherapy consisting of cisplatin and etoposide. No metastases or recurrence were observed 12 mo following surgery. The second patient refused chemotherapy and presented with tumor recurrence 4 mo after surgery. In conclusion, NEC of the gallbladder is an aggressive tumor and the identification of a standardized optimal treatment still requires further research. Our experience together with published studies suggests that radical surgery and adjuvant chemotherapy may improve the prognosis. PMID:25206300

    Laryngeal neuroendocrine carcinomas (LNECs) are rare and highly heterogeneous which present a wide spectrum of pathological and clinical manifestations. Fourteen patients with histologically demonstrated LNEC were collected and analyzed retrospectively. The 14 cases were classified into 3 subtypes: typical carcinoid in 2, atypical carcinoid in 5, and small cell neuroendocrine carcinoma in 7. The mean survival time of the 14 patients in this study was 112.5 months (95% CI, 81.5–143.6). Surgeries were performed for 2 patients of typical carcinoid, and they were alive with no evidence of recurrence after 24 and 47 months of follow-ups. Patients in the atypical carcinoid group were treated with surgeries and postoperative radiotherapy. After 58.4 months of follow-ups (range: 9–144), 2 patients showed no evidence of disease and 1 was lost to follow-up after 72 months. The other 2 patients died of other unrelated diseases. In the small cell neuroendocrine carcinoma group, a combination of chemotherapy and radiotherapy was applied. The mean survival time was 79.7 months (95% CI, 37.9–121.4), and the 5-year survival rate was 53.6%. In conclusion, the clinical behaviors, treatment protocols, and prognosis are different for each subtype of LNECs. PMID:26258144

    A 74-year-old man presented to a physician with a chief complaint of jaundice. He was diagnosed with bile duct carcinoma and admitted to our hospital. Laboratory data revealed abnormally elevated levels of total bilirubin, serum hepatic transaminase, and CA19-9. Endoscopic retrograde cholangiopancreatography revealed neoplastic stenosis from the hilus hepatis to the common bile duct. Abdominal computed tomography (CT) revealed an enhancing tumor in the hilus hepatis bile duct, and positron emission tomography-CT (PET-CT) revealed abnormal fluorodeoxyglucose accumulation in the tumor. Under a diagnosis of hilar cholangiocarcinoma, the patient underwent an extended right hepatectomy and left hepatico -jejunostomy. Immunohistochemically, the tumor cells were positive for neuroendocrine markers such as chromogranin A, synaptophysin, and CD56. The tumor was diagnosed as primary neuroendocrine carcinoma of the bile duct. The patient exhibited multiple liver metastasis 6 months after the operation. Transcatheter arterial chemoembolization (TACE) was performed for the liver metastasis. Although TACE exerted a cytoreductive effect temporarily, multiple liver abscesses developed. The patient died of liver failure 16 months after the operation. We report this rare case of primary neuroendocrine carcinoma of the bile duct. PMID:23267998

    Penile clear cell carcinoma originating in skin adnexal glands has been previously reported. Here, we present 3 morphologically distinctive penile tumors with prominent clear cell features originating not in the penile skin but in the mucosal tissues of the glans surface squamous epithelium. Clinical and pathologic features were evaluated. Immunohistochemical stains were GATA3 and p16. Human papilloma virus (HPV) detection by in situ hybridization was performed in 3 cases, and whole-tissue section-polymerase chain reaction was performed in 1 case. Patients' ages were 52, 88, and 95 years. Tumors were large and involved the glans and coronal sulcus in all cases. Microscopically, nonkeratinizing clear cells predominated. Growth was in solid nests with comedo-like or geographic necrosis. Focal areas of invasive warty or basaloid carcinomas showing in addition warty or basaloid penile intraepithelial neoplasia were present in 2 cases. There was invasion of corpora cavernosa, lymphatic vessels, veins, and perineural spaces in all cases. p16 was positive, and GATA3 stain was negative in the 3 cases. HPV was detected in 3 cases by in situ hybridization and in 1 case by polymerase chain reaction. Differential diagnoses included other HPV-related penile carcinomas, skin adnexal tumors, and metastatic renal cell carcinoma. Features that support primary penile carcinoma were tumor location, concomitant warty and/or basaloid penile intraepithelial neoplasia, and HPV positivity. Clinical groin metastases were present in all cases, pathologically confirmed in 1. Two patients died from tumor dissemination at 9 and 12 months after penectomy. Clear cell carcinoma, another morphologic variant related to HPV, originates in the penile mucosal surface and is probably related to warty carcinomas. PMID:26848799

    Gallbladder small cell carcinoma (SCC) comprises only 0.5 % of all gallbladder cancer and consists of aggressive tumors with poor survival outcomes against current treatments. These tumors are most common in elderly females, particularly those with cholecystolithiasis. We report the case of a 79-year-old woman with gallbladder small cell carcinoma. The patient had intermittent right upper quadrant abdominal pain and was admitted to our hospital due to suspected acute cholecystitis. She regularly received medical treatment for diabetes, hypertension, and dyslipidemia. On initial laboratory evaluation, the levels of aspartate aminotransferase (AST), total bilirubin, and C-reactive protein (CRP) were markedly elevated. She underwent computed tomography (CT) for screening. CT images showed a thick-walled gallbladder containing multiple stones and multiple 3-cm-sized round nodular lesions, which were suggestive of metastatic lymph nodes. After percutaneous transhepatic gallbladder drainage was performed, endoscopic ultrasound-guided fine needle aspiration of enlarged lymph nodes resulted in a diagnosis of small cell carcinoma or adenocarcinoma. However, we could not identify the primary lesion before the surgery because of no decisive factors. We performed cholecystectomy because there was a possibility of cholecystitis recurrence risk and also partial liver resection because we suspected tumor invasion. The final pathological diagnosis was neuroendocrine carcinoma of the gallbladder, small cell type. The tumor stage was IVb, T3aN1M1. The patient died 13 weeks after the surgery. In the present paper, we review the current available English-language literature of gallbladder SCC. PMID:27457076

    Basal cell carcinoma (BCC) is the most common skin cancer with a steadily increasing incidence. Ultraviolet radiation is considered the single most important risk factor for BCC, because the tumor occurs most frequently in sun-exposed areas of the body, with approximately four of five BCCs occurring on the face. BCC occurs infrequently in non-sun-exposed skin. The axilla is one of the most sun-protected areas of the body, and BCC arising at this site is very rare. We herein report a case of adenoid BCC which arose from the axilla in a 33-year-old woman. PMID:27303153

    Primary thyroid paraganglioma (TP) is an uncommon tumor, and in rare cases, this disease tends to mimic medullary thyroid carcinoma (MTC). The present study reports a rare case of primary TP mimicking thyroid carcinoma, accompanied by hyperthyroidism. A 30-year-old female presented with an anterior cervical mass. Pre-operative radiological studies and operative frozen section analysis indicated an atypical MTC. Primary TP was finally diagnosed by pathology and immunohistochemical staining. Laboratory examinations (thyroid hormones tests) and Tc99m emission computed tomography revealed hyperthyroidism. Gene analysis of TP-associated gene mutations was negative. Surgical resection was performed as a curative approach and there is currently no metastasis after 36 months of follow-up. Surgeons must be aware of this disease in order to ensure a correct diagnosis and to prevent them from performing unnecessary procedures. The current study presents a case of primary TP mimicking MTC, discusses the radiographic results and histological characteristics, and provides a review of the associated literature. PMID:26622613

    Between 1984 and 1991, 199 patients underwent laparotomy for epithelial "ovarian" malignancy. In 29 cases (15%) normal-sized ovaries (< 4 cm in diameter) with minimal invasion by papillary serous carcinoma were found. This entity in the setting of peritoneal carcinomatosis has been previously described and is reported here as papillary serous cancer of the peritoneal surface (PSPS). The clinical, surgical, and pathologic features of PSPS are compared with a group of age-, grade-, and stage-matched cases with papillary serous ovarian carcinomas (PSOC). PSPS was also characterized by ascites (mean = 3036 cc), malignant washings (91%), and omental involvement with bulky infiltration and/or multiple tumor nodules (96%). Mean cytoreduction in the PSPS group was 65.5% compared to 79% in the PSOC group (P = 0.049). Patients received combination chemotherapy with platinum-based regimens. In general, there was a poor response to treatment with a disease-free interval of 3.4 and median survival time of 19 months in PSPS compared to 11.7 and 31 months in the PSOC patients. Patients with PSPS have more limited cytoreduction, shorter disease-free interval, and shorter overall survival time. Such differences prompt re-evaluation of treatment modalities for PSPS and recognition that this is a condition distinct from PSOC. PMID:8276289

    Tumor-to-tumor metastasis is an uncommon but well-documented phenomenon. We present a case of a clear cell renal cell carcinoma (RCC) metastasizing to an invasive ductal carcinoma (IDC) of the breast. A 74-year-old woman with a past history of clear cell RCC status after radical nephrectomy underwent right modified radical mastectomy for an enlarging breast mass 3 years after nephrectomy. Histological examination revealed a small focus with distinct morphological features similar to clear cell RCC encased in the otherwise typical IDC. Immunohistochemical studies showed that this focus was positive for CD10 and vimentin, in contrast to the surrounding IDC, which was negative for both markers and positive for Her2/neu. Based on the histological and immunohistochemical features, the patient was diagnosed with metastasis of clear cell RCC to the breast IDC. To the best of our knowledge, this is the first reported case of a breast neoplasm as the recipient tumor in tumor-to-tumor metastasis. PMID:24530247

    Introduction: Aspergilloma is a fungal ball which is composed of hyphal structure fungus, fibrin, mucus and cellular debris and settled in a pre-existing pulmonary cavity or an ectatic bronchial. It may cause colonization in patients with an immunosuppressive and underlying lung disease. Although chest radiography provides valuable information, it can be scanned more effectively by computed tomography (CT). Monitoring fungal ball within the cavity in CT provides establishing the diagnosis. Case report: However, in this case report, we presented a case with operated laryngeal carcinoma whom we first had considered to have metastasis and who had received a diagnosis of aspergilloma in CT and Positron emission tomography (PET). Conclusion: Imaging findings may remain limited in definitive diagnosis of aspergilloma. Therefore, surgical resection will allow for both pathological diagnosis and treatment. PMID:26980939

    Mucoepidermoid carcinomas (MECs) of minor salivary gland origin are rare in children and adolescents and have been reported rarely. Literature regarding their clinical features and biologic behavior is scanty. The purpose of this case report is to discuss the clinical manifestation, diagnosis, and treatment plan of MEC of the palate. A 16-year-old male subject visited the Department of Periodontics, The Oxford Dental College and Hospital, Bangalore, India complaining of a painless swelling in the left posterior area of the hard palate since 6 months. Several clinical, radiographic, and histopathological investigations were carried out to rule out the lesion. Incisional biopsy of the lesion confirmed the diagnosis of lesion as MEC of the palate following which a wide surgical excision with adjacent free margins was carried out. This case report highlights the need for proper diagnosis and treatment plan in the cases of malignant tumors as it can lead to morbidity and mortality. PMID:27143836

    The aim of this study was to clarify the histopathological features of anaplastic thyroid carcinoma in patients who achieved long-term survival. We reviewed 88 anaplastic thyroid carcinoma cases in which the patient survived less than 3 months (short-term survival), and 68 anaplastic thyroid carcinoma cases in which the patient survived more than one year (long-term survival) from the database of the Anaplastic Thyroid Carcinoma Research Consortium of Japan. We examined these cases both histologically and immunohistochemically. Six (6.8%) short-term survival cases and 27 (39.7%) long-term survival cases were considered not to be anaplastic thyroid carcinoma after central review. Of these, 12 were revised to papillary carcinoma with squamous cell carcinoma. In cases without chemotherapy, long-term survival was significantly more common if there was a pre-existing tumor, epithelial growth, or lymphocytic infiltration, and short-term survival was more common if neutrophilic infiltration was present. In cases with chemotherapy, long-term survival was significantly more common if epithelial growth or a squamous cell carcinoma component was present, whereas short-term survival was more common in cases with rhabdoid cells. Immunohistochemical results were not related to survival. Some long-term survival cases showed histological findings other than those typically associated with anaplastic thyroid carcinoma. The presence of a pre-existing tumor, epithelial growth, a squamous cell carcinoma component, no neutrophilic infiltration and lymphocytic infiltration may therefore be favorable prognostic factors in anaplastic thyroid carcinoma.

    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. PMID:12140798

    Calciphylaxis is a relatively rare disorder associated with calcification of small- and medium-sized blood vessels, progressive ischemic skin necrosis, and ulcerations. It is usually seen in patients with end-stage renal disease with secondary hyperparathyroidism and is occasionally seen in primary hyperparathyroidism, hypercalcemia of malignancy, and end-stage liver disease. We report an unusual case of calciphylaxis seen in association with metastatic breast carcinoma in the absence of end-stage renal or parathyroid disease. A 73-year-old woman presented with painful leg ulcers. Serum calcium levels and parathormone levels were within normal limits. Skin biopsies from the ulcers revealed small- to medium-sized subcutaneous arteries with calcification of the media. Some of the arteries were narrowed by fibrointimal hyperplasia and fibrin thrombi. Calcification of the subcutaneous fat, fat necrosis, and suppuration were also seen. Calciphylaxis associated with metastatic osteolytic breast carcinoma is rare. Although end stage renal disease with secondary hyperparathyroidism is the most common cause of calciphylaxis, this case demonstrates that less common conditions with normal serum calcium and parathormone levels may also cause it.

    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. PMID:27602160

    Primary pulmonary synovial sarcoma is a very rare, but highly aggressive tumor. Metastatic pulmonary sarcoma due to hematogenous dissemination is much more common. Hence why in any case of pulmonary sarcoma, whole body survey is necessary to exclude a primary tumor elsewhere. No clinical or radiological presentations are specific for pulmonary sarcoma hence; it is often confused with bronchogenic carcinoma. On the other hand, image-guided fine needle aspiration cytology (FNAC) is very much helpful in diagnosis of bronchogenic carcinoma, whereas, it may be inclusive in cases pulmonary sarcomas including primary synovial sarcoma, especially in cases of huge pulmonary masses. So why image-guided tru-cut core biopsy or open lung biopsy and their histopathological examination, supplemented by immunohistochemistry are preferable for the tissue diagnosis of pulmonary synovial sarcoma, although FNAC and immunocytochemistry may be used for the diagnosis. Surgical resection is treatment of choice, if it is not possible, palliative chemotherapy may be an option. Here, we report a rare case of primary synovial sarcoma which occupied almost whole of the right hemithorax in a 60-year-old male farmer. PMID:26958527

    Thermodynamic parameters of DNA melting in the presence of a peptide bronchogen in various concentrations were estimated on a differential scanning microcalorimeter. Bronchogen was shown to serve as a DNA-stabilizing agent. Bronchogen increased the melting temperature of DNA from calf thymus and mouse liver by 3.1°C in a narrow range of r (molar ratio of bronchogen/DNA b.p., 0.01-0.055). A further increase in r was not accompanied by changes in the melting temperature. The complex melting enthalpy (ΔH(melt)) remained unchanged in this range of r (0.01-1.0). ΔH(melt) for DNA from the thymus and mouse liver was 11.4 and 12.7 cal/g, respectively. Our results indicate that bronchogen is not an adenine-thymine-specific or guanine-cytosine-specific ligand. The type of binding is considered as strong and occasional. The binding occurs with both strands of DNA (mainly with nitrogen bases). PMID:21240358

    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

    Mixed adenoneuroendocrine carcinoma (MANEC) of ampulla is rare, with only 13 cases reported, and the diagnoses were all based on histology mostly after surgery. We describe two new cases with cytological features of signet ring-cell carcinoma mixed with small-cell carcinoma, and intestinal adenocarcinoma mixed with large-cell neuroendocrine carcinoma. Our cases and literature review demonstrate the higher frequency of periampullary-duodenum subtype in MANEC compared with non-MANEC ampullary carcinomas. In accordance, of the 14 MANEC cases with detailed morphology available, the most common glandular components are intestinal-type carcinoma (6/14), followed by goblet carcinoid tumor (3/14), signet ring-cell carcinoma (2/14), pancreatobiliary-type carcinoma (2/14), and pancreatic acinar cell carcinoma (1/14). The intestinal-type carcinoma and goblet carcinoid in MANEC are favorable histological types showing no distant metastasis or mortality (0/9) during 6-36 months follow-up. In contrast, the signet ring cell, pancreatobiliary-type carcinoma, and acinar cell carcinoma are unfavorable with distant metastatic rate and mortality rate of 80% (4/5) during 3-16 months follow-up. The combination of favorable glandular histological types with high-grade neuroendocrine tumors (neuroendocrine carcinoma) has a mortality rate of 0% (0/3), whereas the combination of unfavorable glandular types with low-grade neuroendocrine tumors (e.g., carcinoid, atypical carcinoid) has a mortality rate of 100% (3/3). In addition, younger age (<40 years) seems to be associated with high mortality rate of 100% (2/2). Overall, cytology preparations are able to make the diagnosis of MANEC and distinguish the subcomponents. Disease progression is apparently driven by the carcinomatous component of the tumor.

    2015-01-01

    Anaplastic thyroid carcinoma (ATC) is a rare, poorly differentiated type of thyroid cancer occurring in less than 5% of all thyroid cancers. Patients typically have a poor prognosis with very few options for treatment.2 With current therapy of surgery, chemotherapy, and radiation, median survival is only 6 months from the time of diagnosis. Several mutations in cell cycle regulation have been discovered in ATC that contribute to its undifferentiated state, one of which is the BRAF kinase mutation. This mutation results in activation of the MAPK pathway and uncontrolled cell proliferation. In this case report, a 51 y old male presented with a 2-week history of hoarseness and was diagnosed with ATC. Genetic analysis revealed a mutation in BRAF kinase; the patient subsequently began therapy with vemurafenib, a BRAF kinase inhibitor indicated for melanoma. After an initial response, the patient quickly declined and consequently died from his disease. Anaplastic thyroid carcinoma is a deadly cancer without an effective treatment. Inhibiting mutated enzymes that drive the development of this cancer is a potential drug target that may improve outcomes in patients with ATC. PMID:26176686

    Nevoid basal cell carcinoma syndrome (NBCCS) is a rare autosomal genetic disease caused by a PTCH mutation. The disease is characterized by multiple basal cell carcinomas of the skin, multiple keratocystic odontogenic tumors (KCOTs) in the jaw, palmar and/or plantar pits, bifid ribs, ectopic calcification of the falx cerebri, and skeletal abnormalities. Early diagnosis is difficult in many cases because there may be a number of systemic symptoms. The purpose of this study is to report the case of a 12-year-old girl who was hospitalized with multiple KCOTs that occurred in the upper and lower jaws. Through characteristic clinical symptoms and radiologic findings, she was finally diagnosed as having NBCCS. This study also aims to organize the symptoms often observed in Korea using previously published case reports to provide useful information for the early diagnosis of NBCCS. PMID:27489849

    Primary squamous cell carcinoma (SCC) of the liver is very rare, and few cases have been reported in Korea. Primary SCC of the liver is known to be associated with hepatic cysts and intrahepatic stones. A 71-year-old male was admitted to our hospital, and a abdominal computed tomography scan revealed a 10 × 6 cm mass in the liver. Analysis of a biopsy sample suggested SCC, and so our team performed a thorough workup to find the primary lesion, which was revealed hepatoma as a pure primary SCC of the liver with multiple distant metastases. The patient was treated with one cycle of radiotherapy, transferred to another hospital for hospice care, and then died 1 month after discharge. PMID:27044770

    The most common sites of metastatic differentiated thyroid cancer are the neck lymph nodes, while distant metastases typically involve the lungs, the bones, and less frequently the brain. Uncommon metastatic sites include the liver, adrenal gland, kidney, pancreas, and skin. The epidemiological aspects of thyroid metastases in rare sites are largely unknown and their identification could have a significant impact on patients management. A mini-series of unusual metastatic sites of thyroid carcinoma is proposed as a contribution to current knowledge on anatomopathological characteristics and clinical outcome. Of the six cases that were assessed, the metastases were the following: skin metastases (2), skin and pancreas metastases (1), renal metastasis (1), adrenal metastasis (1), and liver metastasis (1). In our experience, metastases in rare sites do not always represent a negative prognostic factor for disease outcome. In fact they can occur as single distant lesion and if surgically resectable, their treatment can also lead to local disease remission. PMID:26662609

    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

    Background. Gallbladder small cell carcinoma is a rare and highly aggressive malignancy with no established standard of care treatment. We described here a case report of small cell gallbladder cancer and we then performed a comprehensive review of 72 case reports of this disease. Methods. Published case reports of small cell carcinoma of the gallbladder between 1983 and 2014 were reviewed. Treatment modalities and survival were analyzed for metastatic and localized disease. Results. Median overall survival for all patients was 13 months. Metastatic disease was identified in 72% of cases. Treatment of metastatic disease with chemotherapy showed a significant survival benefit (p < 0.001) compared to no chemotherapy, and the use of platinum doublet with etoposide showed a nonsignificant 4-month improvement in survival compared to other chemotherapy regimens (p = 0.13). Adjuvant therapy did not demonstrate an improvement of median overall survival in local disease (p = 0.78). Conclusion. Given the limited available data, systemic therapy with platinum and etoposide should be considered for patients with metastatic small cell carcinoma of the gallbladder. Adjuvant chemoradiation or chemotherapy for treatment of local disease warrants further investigation. PMID:26823665

    Ameloblastic carcinoma is a rare and malignant odontogenic tumor. Approximately, 100 cases of ameloblastic carcinomas have been reported in the literature, with fewer than 10 reported cases of an even more rare variant with spindle-cell differentiation. Although it is presumed that most ameloblastic carcinomas arise de novo, it also appears capable of proliferating as carcinoma ex ameloblastoma. Without a full past history, the exact origin of these tumors can be unclear. The exact classification becomes further questionable when both an intraosseous and peripheral tumor exists. This currently reported case has been present for at least 4 years before the patient presenting for care. However, without prior biopsy, the etiology and category of this ameloblastic carcinoma is speculative. Our case represents a histologically unequivocal case of ameloblastic carcinoma. Based on tumor morphology, questions still remain, as to whether it arose de novo, or as carcinoma ex ameloblastoma. The possibility of categorizing the current lesion as a spindle cell variant also exists because of the presence of a prominent population of malignant epithelial spindled cells arranged in fascicles. The authors believe that this ameloblastic carcinoma would best be subclassified as a rare spindle cell variant, based on the prominent spindle cell component. PMID:25939122

    Malignant tumours of the submandibular salivary glands are rare entities. Most common malignant tumour of submandibular gland is mucoepidermoid carcinoma. Histological finding of squamous cell carcinoma is very rare in submandibular salivary gland. Metastasis from distant primary squamous malignancy, direct invasion from cutaneous or mucosal squamous carcinoma, squamous component of mucoepidermoid carcinoma or primary squamous cell carcinoma of salivary origin are some of the possible causes. Of these, the latter is distinctly uncommon. Primary squamous malignancy is diagnosed only after ruling out other possible explanations. A positive mucin stain in the tumour or synchronous/ metachronous squamous carcinoma elsewhere excludes the diagnosis of a primary carcinoma. Primary squamous carcinoma is seen most commonly in parotid gland and rarely in submandibular gland. We present a case of primary squamous cell carcinoma of right submandibular salivary gland in a 45-year old-man. This case is presented for the rare entity of primary squamous cell carcinoma in submandibular salivary gland. PMID:26435997

    52 patients with bronchogenic carcinoma were studied preoperatively by means of conventional tomography and CT. The results were compared with surgical findings to evaluate the accuracy of these methods in detecting mediastinal lymph node involvement. 323 mediastinal lymph nodes were identified by CT and 237 of these were studied histologically. In 25% of lymph nodes with diameter between 0.5 and 1 cm metastases could be identified. On the other hand, 25% of lymph nodes measuring up to 3 cm did not contain metastases. The results varied in different regions (pre- and paratracheal, azygos region, aorto-pulmonary, subcarinal). The probability of involvement of small nodes was doubled if there were in regions neighbouring metastases. In view of the high incidence of false positive and false negative CT findings, conventional methods were sufficient in the presence of definite pathological findings. PMID:1319769

    Pituitary carcinomas are rare malignant neoplasms with diagnostic and management challenges. Patients with pituitary carcinomas have extremely poor outcomes. In this report, the authors describe two cases of pituitary carcinomas with intraspinal metastasis (Case 1: 42-year-old man with a history of pituitary adenoma 16 years ago developed an intraspinal lesion at C4-C5; Case 2: 26-year-old women with a history of growth hormone-producing pituitary adenoma 9 years ago developed intraspinal lesion in the sacral canal). Both patients underwent spine surgery. The intraspinal lesions were confirmed as metastatic pituitary carcinomas based on the histomorphology and immunohistochemical stains. The authors reviewed the literature for the diagnosis, treatment, and prognosis of intraspinal metastasis from pituitary carcinomas. PMID:26464743

    Renal cell carcinoma is a potentially lethal cancer with aggressive behavior and a propensity for metastatic spread. Due to the fact that the patterns of metastases from renal cell carcinomas are not clearly defined, there have been several reports of cases of renal cell carcinoma associated with rare metastatic sites and atypical presenting symptoms. The present review focuses on these atypical rare clinical presentations of renal cell carcinomas both at the time of diagnosis of the primary tumor but also in the years after radical nephrectomy.

    Pulmonary scar carcinoma was described as a distinct clinicopathological entity over 50 years ago. There are many theories on the formation of this entity. We present three cases of pulmonary scar carcinoma with a high ratio of adenocarcinoma. One patient had a favorable postoperative course despite a 14-month delay in treatment. Necropsy specimen of another patient showed two primary scar carcinomas unrelated to each other. Literature review and discussion of etiology, diagnosis, and treatment modalities of pulmonary scar carcinoma were done. Pathogenesis and prognosis of the neoplasms associated with apical scars are not clearly understood. PMID:7501207

    Prostate adenocarcinoma can manifest as a fairly indolent tumor or as a very aggressive cancer with significant invasive and metastatic potential. Common metastatic sites include bone, liver, lymph nodes, and adrenal glands. Dermatologic manifestations are rare. We present a case of a man who presented with breast skin changes that mimicked inflammatory breast carcinoma with specialized testing ultimately giving a diagnosis of metastatic prostatic adenocarcinoma. A 78-year-old man presented with left breast redness and swelling. Examination revealed an erythematous rash with subcutaneous edema over the left hemithoracic area. A breast ultrasound showed no focal mass, and a breast core biopsy had no evidence of tumor. A skin biopsy showed metastatic carcinoma in dermal lymphatics, and the tumor was found to have no estrogen or progesterone receptors or HER2 expression. Computed tomography scans, positron emission tomography, and a nuclear bone scan revealed widespread skeletal metastases. The patient received a 3-month course of capecitabine and cyclophosphamide with no improvement in his skin lesions. Subsequent immunohistochemical staining on the tumor specimen was positive for prostate-specific antigen (PSA) and alpha-methyl-CoA-racemase, confirming a diagnosis of metastatic prostatic adenocarcinoma. He received leuprolide and bicalutamide and demonstrated significant improvement with near-complete resolution of his skin lesions and a decrease in his PSA level. Prostatic adenocarcinoma presenting initially as a breast malignancy is a rarely recognizable clinical event. Undoubtedly, increased awareness and recognition of the rare entity described herein will allow for the prompt initiation of specific therapies, which might be of benefit to many patients.

We present a case of 58 years old male presented with painless left scrotal mass, which was discovered to be an intrascrotal metastases appeared 3 years after nephrectomy for ipsilateral renal cell carcinoma. We believe that the rarity of the metastatic site and the intriguing possible mechanism of spread make an interesting case for clinicians and could add more follow-up measures for patients treated from renal cell carcinoma.

    Cutaneous metastases of the breast carcinomas can present clinically as nodules, plaques and tumors (most commonly as nodules) as well as ‘erysipelas-like’ lesions are known as ‘carcinoma erysipeloides’. We want to share our experience in diagnosing a middle-aged lady with carcinoma erysipeloides secondary to breast carcinoma and her management as this is commonly misdiagnosed as cellulitis or scleroderma in general practice. Unfortunately, the patient had presented to us at a late stage with wide-spread metastasis, and as such, chemotherapy was the only available option. She expired after her third cycle of chemotherapy.

    Thymic neuroendocrine carcinoma (NEC) is a rare type of cancer. Unlike other thymic epithelial tumors and carcinoids originating in other locations, thymic NEC possesses a more aggressive biological behavior, including invasion to proximal structures, local recurrence and distant hematogenous metastasis. Distant metastasis is often observed in the bones, lungs, spleen, liver and adrenal glands. However, pancreatic metastasis resulting from thymic NEC is extremely uncommon, and only a few cases of patients with this disease have been reported. The current study presents the case of a patient with pancreatic metastasis resulting from thymic NEC. The patient was admitted to hospital with an anterior mediastinal neoplasm, which was identified using chest enhanced computed tomography. The patient underwent a monobloc excision of the tumor with resection of involved structures. Subsequently, a pathological diagnosis of atypical thymic carcinoid was provided, according to the morphological characteristics observed and the expression of neuroendocrine markers, as identified by immunohistochemistry. Following surgery, the patient received adjuvant chemotherapy and radiotherapy. However, ~2 years after surgery, metastasis at the pancreatic head was identified. The patient underwent a total pancreatectomy and splenectomy, and did not receive any post-operative therapies; however, the patient succumbed to the disease 9 months following surgery. Overall, the results from the present study demonstrate the clinical features of thymic NEC, which may aid with the diagnosis of this rare disease in other patients. PMID:26998098

    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

    Carcinoma erysipeloides (CE) is an uncommon but distinctive form of cutaneous metastasis that usually manifests clinically as a fixed erythematous patch or plaque resembling cellulitis or erysipelas. The inflamed area may show a distinct raised edge at the periphery and also edema secondary to lymphatic obstruction. Histologically, dense carcinoma cells in the dermal vascular channels and dense perivascular lymphocytic infiltrate may be seen. CE may rarely be the first sign of “silent” tumor of breast. We report a case of a 52-year-old married lady who presented with a three months history of pruritic erythematous patches over the left side of the breast that was resistant to all topical treatments and was diagnosed as erysipeloid breast carcinoma.

    Background: Description of three cases of metastatic esophageal carcinoma to the iris and focus on management strategies. Methods: A 48-year-old man (Case 1) with previously treated stage IV esophageal carcinoma presented with blurred vision in the left eye (OS) for 3 weeks. Initial fine needle aspiration biopsy (FNAB) was negative for malignant cells, so incisional biopsy was performed and confirmed metastatic carcinoma. A 53-year-old man (Case 2) with previously treated stage III esophageal cancer experienced 2 months of pain and 1 month of blurred vision OS. Documented tumor growth suggested esophageal carcinoma metastasis. A 65-year-old man (Case 3) with previously treated stage IV esophageal carcinoma developed hyphema in the right eye (OD), and FNAB confirmed metastatic carcinoma. Results: Case 1 was treated with external beam radiotherapy (EBRT), delivered over 16 days which resulted in complete tumor regression. Case 2 received stereotactic body radiotherapy (SBRT) over 21 days leading to complete tumor regression. Case 3 was treated with plaque radiotherapy over 4 days, resulting in complete tumor regression. Conclusions: In all three cases, radiotherapy was employed, and enucleation was avoided. Plaque radiotherapy achieved tumor control in a shorter period of time (4 days) compared to EBRT (16 days) or SBRT (21 days). Knowing the short life expectancy of these patients, plaque radiotherapy appears most favorable. PMID:27433035

    Introduction 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. Presentation of case 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. Discussion Most colorectal carcinomas associated with inflammatory bowel disease are histologically similar to the sporadic type, and tumors with neuroendocrine features are very unusual. Conclusion Very rare case of sigmoid colon carcinoma with neuroendocrine features arising in a patient with UC was described. PMID:27136202

    Embryonal carcinoma in two cases of complete androgen insensitivity syndrome (CAIS) is reported. In both cases gonadectomy carried out for prophylactic purposes led to the discovery of a localized embryonal carcinoma with areas of anaplastic seminoma in one case. In non-neoplastic tissue, gonad morphology in both cases was typical of AIS. Prevalently hypotrophic aspects, especially in the interstitial gland, were found in case 2. This may explain the different endocrine profile in the two cases before gonadectomy. Our study, aside from series of psycho-sexual problems, shows, according to all Authors, that the most serious complication is the high risk of malignancy after puberty in patients with AIS.

    Salivary gland carcinomas are very rare in the nasopharynx, with the most frequent histologic types being adenoid cystic carcinoma, mucoepidermoid carcinoma and adenocarcinoma, not otherwise specified. Myoepithelial carcinoma (MECA) is a rare tumor of the salivary glands, and there are only three previously reported cases of nasopharyngeal MECA. The case presented is the fourth reported case of MECA in the nasopharynx. Due to the morphologic heterogeneity of MECA, immunohistochemistry is indispensable in ascertaining the diagnosis. MECA is a locally aggressive tumor, but the long-term prognosis of this tumor in the nasopharynx remains uncertain. In our case the tumor was unresectable and the patient was given chemo-radiotherapy. Despite this, residual tumor was seen on nasoscopy 5 months after initial diagnosis and was documented on a re-biopsy which displayed the same histomorphologic features as the original tumor.

    Sarcomatoid Carcinoma (SC) is an unusual and aggressive variant of squamous cell carcinoma, which frequently recurs and metastasizes; for this reason, the right diagnosis is very important. It is considered to be a biphasic tumor made up of cells from squamous and spindle cells carcinoma with a sarcomatous aspect, but of epithelial origin. The diagnosis often represents a clinical-pathological challenge where the study with immunohistochemical technique (IHC) is key to the histopathological diagnosis. The reported cases related to oral mucosa are limited. In this work we present two SC cases where the use of IHC allowed us to achieve a conclusive diagnosis. PMID:25785207

    Molecular testing for anomalies, such as epidermal growth factor receptor mutations and anaplastic lymphoma kinase (ALK) rearrangement, is part of the current standard of care for non-small cell lung cancer, particularly adenocarcinoma. ALK rearrangement occurs most frequently in adenocarcinoma cells and rarely in non-adenocarcinoma cells. We herein report a rare case of pleomorphic lung carcinoma with ALK rearrangement in both its adenocarcinoma and spindle cell components.

    Small cell carcinoma (SCC) in the head and neck region is an extremely rare high-grade malignant tumor. The authors report a case of an SCC occurring in the left buccal region. An 85-year-old man exhibited left cheek swelling that rapidly increased in size. Histopathological examination revealed invasive growth of an SCC into the musculo-adipose tissue. Immunohistochemically, the tumor cells were positive for cytokeratin (AE1/AE3), neuron-specific enolase (NSE) and CD56, but negative for cytokeratin 20. The patient received chemotherapy and radiotherapy, which resulted in marked regression of the tumor. Surgical resection was performed. The serum levels of NSE and pro-gastrin-releasing peptide (pro-GRP) increased and multiple metastases of the tumor occurred 1 month after surgery. SCCs tend to exhibit aggressive invasion and metastasis so chemotherapy for the whole body is recommended to prevent dissemination of the tumor cells. Serum levels of NSE and pro-GRP are considered to be useful tumor markers for understanding the status of the tumor and the clinical symptoms. PMID:19464148

    A 70-year-old woman was referred to our clinic for evaluation and treatment of a recurring case of adenoid cystic carcinoma of the lacrimal gland. She had been diagnosed with this tumor three years earlier, and a local resection was attempted on two occasions. We encountered this patient on the third recurrence of the tumor, and a thorough work-up revealed extensive local involvement but no metastases. A total exenteration of the right orbit was then performed with aggressive resection of local extension followed by irradiation. Thirteen years later, our patient presented with metastases throughout her scalp. She died shortly thereafter, having survived a total of 16.5 years after the time of her initial treatment and 13 years after exenteration with bony removal of the orbit and irradiation. A review of the literature reveals that this patient had one of the longest reported survival times in the literature from the time of initial treatment. Also noteworthy is the 13 years this patient survived after aggressive surgical resection combined with radiotherapy following two previous incomplete resections. PMID:8193073

    Background Minimal uterine serous cancer (MUSC) or serous endometrial intraepithelial carcinoma (EIC) has been described by many different names since 1998. There have been very few cases reported in literature since EIC/MUSC was recognized as a separate entity. The World health Organization (WHO) Classification favors the term serous EIC. Although serous EIC is confined to the uterine endometrium at initial histology diagnosis, a significant number of patients could have distal metastasis at diagnosis, without symptoms. Serous EIC is considered as being the precursor of uterine serous cancer (USC), but pure serous EIC also has an aggressive behavior similar to USC. It is therefore prudent to have an accurate diagnosis and appropriate surgical staging. There are very few published articles in literature that discuss the pure form of serous EIC. The aim of this series is to share our experience and review evidence for optimum management of serous EIC. Patients and methods We report a series of five women treated in our institute in the last 3 years. We reviewed the relevant literature on serous EIC and various management strategies, to recommend best clinical practice. Conclusion Pure serous EIC is a difficult histopathological diagnosis, which requires ancillary immunohistochemical staining. It can have an aggressive clinical behavior with early recurrence and poor survival. Optimum surgical staging, with appropriate adjuvant treatment, should be discussed when treating these patients.

    To explore the clinical pathological characteristics and improve the recognition in the diagnosis and treatment of basal cell carcinoma (BCC) of prostate. Three cases of BCC of prostate were reported and the relevant literature was reviewed to investigate the diagnosis and treatment of this disease. We analyzed three cases of prostatic BCC. Their ages were within a range of 57 to 83 years. One of them complained of hematuria and two complained of dysuria. All of them presented with prostatic hyperplasia. Two of them presented with high prostate specific antigen (PSA) and one with normal PSA. Case 1 had prostate cancer invasion of bladder, rectal fascia, with lymph node metastasis, bone metastasis and lung metastases. The patient received bladder resection+bilateral ureteral cutaneous ureterostomy+lymph node dissection on November 2, 2014 . Postoperative pathological diagnosis showed BCC. Reexamination of pelvic enhanced MRI in January 8, 2015 suggested pelvic recurrence. Abdominal enhanced CT showed multiple liver metastases and pancreatic metastasis on July 11, 2015. Prostate cancer specific death occurred in October 2015. Case 2 was diagnosed as BCC in prostate biopsy on March 27, 2015. Positron emission tomography and computed tomography (PET-CT) showed pulmonary metastasis and bone metastasis. Then the patient received chemotherapy, endocrine therapy and local radiation therapy. Reexamination of PET-CT on January 11, 2016 showed that the lung metastase tumors and bone metastase tumors were larger than before. Up to January 10, 2016, the patient was still alive. Postoperative pathological changes of transurethral resection of prostate (TURP) in case 3 showed BCC might be considered. The PET-CT suggested residual prostate cancer, which might be associated with bilateral pelvic lymph node metastasis. In April 20, 2016, the review of PET-CT showed pelvic huge irregular hybrid density shadow, about 14.5 cm×10.0 cm×12.9 cm in size, and tumor recurrence was

    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.

    Papillary carcinoma of the thyroid is the commonest type of thyroid cancer. Laryngeal infiltration from papillary thyroid carcinoma is extremely rare, with only a few cases of partial invasion described in the literature. We present a very unusual case of complete infiltration of both thyroid and cricoid cartilages from a neglected papillary thyroid carcinoma in a 59-year-old male. This sequel resulted from refusal of the patient to undergo treatment when initially diagnosed. An invasion to such an extent has not been described in the literature before, and in this case warranted a total laryngectomy followed by radioactive iodine. Prompt management of papillary carcinomas is crucial for avoiding such complications. Future guidelines should include management options for the patients who deny treatment initially. PMID:27458595

    It has been reported that cisplatin-based chemotherapy shows beneficial effects in certain patients with advanced thymic carcinoma. However, the usefulness of salvage therapy has not been reported. We focused on a new anthracycline agent, amrubicin, combined with platinum compounds as salvage chemotherapy in patients with thymic carcinoma. Six cases of unresectable and locally advanced thymic carcinoma relapsed from prior cisplatin-containing chemotherapy were treated with amrubicin (30-40 mg/m(2) day 1-3) plus platinum compounds (cisplatin 60 mg/m(2) day 1 or nedaplatin 70 mg/m(2) day 1) chemotherapy as salvage chemotherapy. Two patients showed a partial response. However, Grade 3/4 neutropenia and thrombocytopenia occurred in all and two of the patients, respectively. We conclude that thymic carcinoma is sensitive to platinum-based chemotherapy and that amrubicin appears to have significant activity against thymic carcinoma. The major toxicity is hematological toxicities. PMID:19415537

    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.

    Squamous cell carcinoma (SCC) is classified in many subtypes or forms; one of them is the acantholytic squamous cell carcinoma, also called pseudoglandular, adenoid, epithelioma dyskeratoticum segregans, or adenoacanthoma. Researching and analyzing nine cases of acantholytic squamous cell carcinoma, we intend to verify if the data provided by the cases studied can be validated by the scientific literature. All the cases presented lesions found on the head and neck skin, with two exceptions - one on the larynx and the other one on the tonsil, all of them ulcerated lesions. In two cases, the tumors developed on the skin, in preneoplasic lesions (actinic keratosis). The tumors had dimensions between 4/3/4 mm and 100/90/36 mm. During one year, two of the cases studied presented multiple recurrences. We also found two cases of metatypical carcinoma accompanied the acantholytic variant of squamous cell carcinoma. None of the analyzed cases presented distant metastasis. The histopathological criteria for selection were: keratinised squamous tumor cell type, adenoid structures with round spaces with a defined wall of at least one cell width, spaces with isolated or grouped dyskeratotic acantholytic cells.

    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. PMID:25043771

    2010-01-01

    Background The most common type of carcinoma associated with ulcerative colitis (UC) is adenocarcinoma. We present a case of primary rectal small cell carcinoma in a patient with a history of UC. Methods A 34-year-old male diagnosed with UC for 10 years was not consistent with the usual annual follow-up and presented with mucoid-bloody diarrhea. Colonoscopy revealed a rectal mass 2 cm distant from the anal verge. The patient underwent a total proctocolectomy with preservation of the anal sphincters, construction of an ileal reservoir, anastomosis of the reservoir to the anus (J configuration) and protective loop ileostomy. Results Histological examination showed undifferentiated small cell carcinoma. Conclusions This is the first case of small cell carcinoma in a background of UC reported to be treated surgically and the patient and has no reccurence 18 months postoperatively. PMID:21087512

    Primary colon carcinoma within an inguinal hernia sac is very rare and most reported cases were found at emergency open surgery for an incarcerated hernia. We report a case of incarcerated sigmoid colon carcinoma diagnosed preoperatively and treated with elective laparoscopic surgery. A 67-year-old man with a 2-year history of swelling of the scrotum and a breast lump was referred to us for surgical treatment of an irreducible left inguinal hernia and a right breast tumor. Blood examination results showed severe anemia. Computed tomography scan and endoscopic biopsy confirmed sigmoid colon carcinoma incarcerated in the left inguinal hernia. Thus, we performed definitive laparoscopic sigmoidectomy and conventional hernia repair for preoperatively diagnosed sigmoid colon carcinoma within an inguinal hernia. PMID:23846798

    Laryngeal sarcocystosis is an uncommon zoonotic coccidian protozoal infestation of human beings. The authors reviewed the pathology of 1,063 laryngeal biopsies over the past 10 years (2000 to 2009). Only one case of laryngeal sarcocystosis accompanying laryngeal squamous cell carcinoma was identified. The overall prevalence of laryngeal sarcocystosis was 0.094%. The case was a 66-year-old man who presented with voice hoarseness for six months. Physical examination and computed tomography revealed an ulcerative exophytic mass on the right true vocal cord, suggestive of laryngeal carcinoma. He underwent a right frontolateral partial laryngectomy. Histopathology showed a nonkeratinizing squamous cell carcinoma with Sarcocystis spp in the vocalis muscle. He was followed up and enrolled in speech therapy. The authors briefly review the clinicopathologic features and pathogenesis of muscular sarcocystosis and concurrent laryngeal sarcocystosis and squamous cell carcinoma. PMID:22299431

    Purpose The incidence of Hepatocellular carcinoma (HCC) is on the rise, but what is causing that trend has remained a mystery. Mycotoxins are almost entirely ignored health problems, and sometimes actually naively belittled in advanced medical care. Ochratoxin A (OTA) is one of the most abundant food contaminating mycotoxins worldwide that is carcinogenic, but no studies have evaluated its levels in HCC patients. Therefore, this study was designed to monitor the presence of OTA in the serum of HCC patients and to quantify the strength of the association between OTA and HCC. Methods We conducted a case control-based study on 61 participants. Thirty-nine were HCC cases identified between 2010 and 2012 and individually matched by age, sex, residence and date of recruitment to 22 healthy controls. Serum OTA and alpha-fetoprotein levels were measured by using high-performance liquid chromatography (HPLC) and enzyme-linked immunosorbent assay, respectively. Results HPLC analysis of 61 serum samples indicated that the highest incidence of elevated OTA was found in the HCC group and was 5-fold higher than in the control group. The concentration of OTA in the HCC group ranged between 0.129 and 10.93 ng/mL with a mean value±SD of 1.1±0.3 ng/mL, while in the normal group it ranged between 0.005 and 0.50 ng/mL with a mean value±SD of 0.201±0.02 ng/mL. The odds ratio for HCC patients presenting OTA levels above the cut-off of 0.207 (calculated by the receiver operating characteristic curve) was 9.78 (95% confidence interval = 2.9095–32.9816, P = 0.0002) with respect to normal controls, suggesting that HCC is 9.8 times as frequent in the exposed group to OTA. Conclusion Our results reveal a strong association between the presence of OTA and HCC, which may offer a coherent explanation for much of the descriptive epidemiology of HCC and suggest new avenues for analytical research.

    An 89-year-old man was admitted to our hospital for thorough investigation of refractory diabetes mellitus, which revealed primary squamous cell carcinoma of the duodenum. After two courses of chemotherapy, follow-up esophagoduodenogastroscopy and duodenal biopsy showed no evidence of tumor. No findings were suggestive of recurrence of the primary lesion 19 months after starting chemotherapy. This case suggests that chemotherapy including TS-1 may be effective for treating unresectable primary squamous cell carcinoma of the duodenum. PMID:25482907

    Carcinomas of the lacrimal drainage apparatus are rare and due to their aggressive behavior, they usually require extensive surgical treatment. We report a unique case of a 60-year-old man presenting with proptosis found to have a mass in the lacrimal drainage system on magnetic resonance imaging. Histology revealed a high-grade carcinoma with morphologic features of salivary gland duct carcinoma. Immunohistochemistry showed an extensive positive staining to androgen receptor. This is the first report of salivary gland-like duct carcinoma of the lacrimal drainage apparatus. Androgen receptor should be included in the immunohistochemical panel for the diagnostic work-up of lacrimal drainage system carcinomas, which resemble salivary gland duct carcinoma. This finding could have important diagnostic and therapeutic implications. PMID:26766124

    Invasive micropapillary carcinoma is a recently identified neoplasm. A 77-year-old-female was admitted to the hospital due to progressive loss of weight and nausea. Endoscopic biopsy of the antral/prepyloric located mass was diagnosed as moderately differentiated adenocarcinoma. Subtotal gastrectomy and regional lymph node resection were performed. The tumor was composed of moderately differentiated cells arranged in micropapillary structures with only a few poorly formed glandular foci in lamina propria. Immunohistochemically, neoplastic cells of micropapillary and focal conventional adenocarcinoma areas were diffusely positive for pancytokeratin, cytokeratin 7 and epithelial membrane antigen. In micropapillary areas, membranous and peripheral cytoplasmic positivity with epithelial membrane antigen in outside of the cell clusters called "inside-out polarity" pattern that is characteristic for invasive micropapillary carcinoma were seen. Invasive micropapillary carcinoma is very rare in the stomach in the English literature. PMID:26456969

    Introduction Splenic metastasis of gallbladder carcinoma is extremely rare. Specific anatomical, histological, and functional properties of spleen are believed to be responsible for the rarity of solitary splenic metastasis. Presentation of case We present the case of a 62-year-old female who developed metachronous splenic metastasis of adenosquamous carcinoma of the gallbladder. We performed central bisegmentectomy of the liver for gallbladder carcinoma. The patient subsequently presented 3 months later with isolated splenic metastasis and liver metastasis. Splenectomy and partial hepatectomy was performed at this time. Histological examination confirmed metastatic adenosquamous carcinoma of the gallbladder. No signs of recurrence were observed at 3 months after the second surgery. Discussion Although splenectomy provides a potential means of radical treatment in patients with isolated splenic metastases, it should be performed with caution as splenic metastatic lesions may represent the initial clinical manifestation of systemic metastases at multiple sites. In this case, radical surgery was performed following the confirmation of no new unresectable metastatic lesions or systemic dissemination. Conclusion This is the first report on the adenosquamous splenic metastasis from the gallbladder carcinoma. Curative resection may be the treatment of choice for prolonging survival in patients with the splenic metastasis of gallbladder carcinoma. PMID:26852359

    The current study describes a case of adenosquamous carcinoma originating from a thyroglossal duct cyst (TGDC). A 77-year-old man presented with an asymptomatic mass in the left mid-neck, which was soft and mobile on palpation. Fine-needle aspiration was performed, but cytology did not detect any malignant cells. Computed tomography demonstrated a single cystic lesion in the left lobe of the thyroid gland; therefore, surgery was performed on the suspected thyroid cyst. However, it was identified intraoperatively that the lesion was separated from the thyroid gland and instead adhered to an additional hyoid bone; therefore, the Sistrunk procedure was performed. Histopathological examination of the resected tumor confirmed the diagnosis of adenosquamous carcinoma originating from a TGDC. Carcinoma arising from a TGDC is rare, and accounts for 1% of all TGDC cases. The most common subtype of carcinoma associated with TGDC is papillary carcinoma, whilst adenosquamous carcinoma developing from a TGDC is extremely rare, with only one case currently reported in the literature. Although a consensus for the management of this disease has not yet been established, adequate surgical excision with long-term follow-up is currently the preferred treatment. PMID:27073536

    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.

    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.

    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.

    The patient was a 53-year-old woman in whom ultrasonography of the breast revealed a lobular mass, 14 mm in diameter, in the right AB region. Spindle cells were obtained on fine-needle aspiration biopsy, but it was not possible to diagnose whether the tumor was benign or malignant. Contrast-enhanced magnetic resonance imaging showed a mass with a cystic component that was darkly stained in the early phase. Needle biopsy showed a dense proliferation of atypical spindle cells with no distinct epithelial-like arrangement. The differential diagnosis included mesenchymal malignant tumors such as fibrosarcoma, some phyllodes tumors, and epithelial tumors with sarcomatoid differentiation. Immunostaining revealed that the tumor was cytokeratin (AE1/AE3)-negative, partially CAM 5.2-positive, p63-positive, S100-negative, SMA-positive, partially vimentin-positive, with a Ki-67 index of 80% and negativity for ER, PgR, and HER2. Spindle-cell carcinoma was thus diagnosed. A partial right mastectomy with sentinel lymph-node biopsy was performed. Immunostaining of the resected specimen confirmed spindle cell carcinoma. The General Rules for Clinical and Pathological Recording of Breast Cancer classify spindle cell carcinoma as a special type of invasive cancer with a sarcomatoid structure, consisting of spindle-shaped cancer cells. This type of carcinoma is extremely rare, accounting for less than 1% of all breast cancers. PMID:25731380

    A heterogeneous spectrum of epithelial alterations and atypical lesions affect the squamous epithelium of penile mucosal anatomical compartments. Analogous to other genital sites, the terminology utilized to define the lesions is variable. The few pathologic studies of penile precancerous lesions are mostly related to carcinoma in situ and human papilloma virus (HPV), and the information on low-grade atypical lesions is limited. The objective of this study was to comprehensively describe the morphologic features of all epithelial alterations, benign and atypical, low grade and high grade, associated with invasive squamous cell carcinoma of the penis and to investigate their relation with each other and with subtypes of invasive carcinoma. We also propose herein a simple and reproducible nomenclature for penile precancerous abnormalities until more biological, molecular, or epidemiologic information on the lesions is available. Two hundred and eighty-eight penectomy and circumcision specimens with invasive squamous cell carcinoma were pathologically evaluated. Carcinomas were classified as usual, verrucous, papillary not otherwise specified, warty (condylomatous), basaloid, and mixed. Associated lesions were classified as squamous hyperplasia and squamous intraepithelial lesions of low and high grade (LGSIL and HGSIL). In LGSIL, atypia was confined to the lower third, and in HGSIL, atypical cells affected at least two thirds of the squamous epithelium. Subtypes of SIL were squamous, warty, basaloid, warty-basaloid, and papillary. Squamous hyperplasia, the most common lesion, was found in 83% of the cases, followed by LGSIL (59%) and HGSIL (44%). In 62% of the cases more than 1 associated lesion was present per specimen. A sequence from squamous hyperplasia to low-grade to high-grade SIL was seen frequently. Squamous hyperplasia was more commonly associated with usual squamous, papillary, and verrucous than with warty and basaloid invasive carcinomas. LGSIL was

    Squamoid eccrine ductal carcinoma is a poorly documented skin adnexal carcinoma showing squamous and duct differentiation. It is regarded to be of low-grade malignant potential, but limited follow-up information is available. To study their clinical behavior and histologic features, 30 squamoid eccrine ductal carcinomas were identified from departmental and referral files. Hematoxylin and eosin-stained sections were reviewed, and immunohistochemistry for carcinoembryonic antigen and epithelial membrane antigen was examined to confirm duct differentiation. Clinical follow-up was obtained from patient records and referring pathologists. The tumors presented as nodules or plaques (median size, 1.0 cm; range, 0.5 to 2.5 cm) with a predilection for the head and neck (77%). The patients were elderly (median age, 79.5 y; range, 10 to 96 y) with a male predominance. Histologically, these poorly demarcated tumors were characterized by an infiltrative growth pattern within the dermis and additional invasion of subcutis in 70%. Median tumor thickness was 4.3 mm (range, 1.5 to 18 mm). Superficially, the tumors resembled well-differentiated squamous cell carcinoma. In the deeper reaches, they were organized in cords and strands showing duct differentiation in a desmoplastic stroma. Cytologic atypia was moderate to severe. Ulceration (47%), necrosis (23%), and perineural and lymphovascular infiltration (27% and 6%, respectively) were additional features. Follow-up data (median, 29 mo; range, 7 to 99), available for 24 patients (80%), revealed a local recurrence rate of 25%. Three patients had lymph node metastasis, and 1 patient died of metastatic disease. Our study outlines the histologic characteristics of squamoid eccrine carcinoma and emphasizes its clinical behavior with risk for local recurrence and potential for more aggressive behavior with metastasis and rare disease-related mortality.

    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. PMID:24114644

    Background Squamous cell carcinoma of the scrotum is rare and its development in the scar of Fournier's gangrene is still rarer. Case presentation A 65-year-old gentleman presented with a small non-healing ulcer developing on right hemi-scrotum two years after the treatment for Fournier's gangrene. On histological examination it was found to be squamous cell carcinoma. He was successfully managed by surgery in the form of wide local excision and ilio-inguinal lymph node dissection followed by adjuvant radiotherapy and chemotherapy. Conclusions Squamous cell carcinoma can develop in the scar of Fournier's gangrene after a long delay, which differentiates it from other scar carcinomas or Marjolin's ulcer. PMID:15113443

    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.

    Primary transitional cell carcinoma (TCC) of the ovary is a rare and recently recognized subtype of ovarian surface epithelial-stromal cancer. Pure forms of the TCC ovary account for only 1% of surface epithelial carcinomas. The clinical presentation is indistinguishable from other types of ovarian cancers. They have a favorable response to chemotherapy than other surface epithelial cancers. We report a case of 55-year-old woman who presented with a hard mass in the abdomen. Computed tomography-diagnosed it as a carcinoma of the ovary. Tumor was immunoreactive with Wilms’ tumor protein-1 and nonreactive with cytokeratin 7 (CK7) and CK20. Histopathology diagnosis of primary TCC of the ovary was made. These tumors are needed to be differentiated from metastatic TCC from other sites and undifferentiated carcinomas of ovaries. Clinical features and immunohistochemistry are helpful. Surgical resection is the primary therapeutic approach followed by standardized chemotherapy. PMID:27127747

    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. PMID:27123296

    Aberrant breast tissue is usually found in proximity to the normal breast, that is, in the axillary, sternal or clavicular regions. Carcinoma occurs more frequently in the aberrant tissue of the axilla than the extra-axillary site though the overall incidence of tumors of aberrant breast tissue is low. To our knowledge, studies regarding the carcinoma of aberrant breast tissue of the extra-axillary site have been reported rarely. Here we report a recent case of carcinoma originating from the extra-axillary aberrant breast tissue, presenting as a subcutaneous nodule on the right upper anterior chest wall. It is suggested that subcutaneous nodules of uncertain origin around the periphery of the breast should be suspected for breast carcinoma as a differential diagnosis and treated properly.

    Calyceal diverticula are rare outpouchings of the upper collecting system lying within the renal parenchyma. These often contain stones, however, carcinoma within a calyceal diverticulum is uncommon. The present study reports a case of invasive urothelial carcinoma within a calyceal diverticulum associated with renal stones. A 70-year-old male with a left renal mass identified by abdominal computed tomography was referred to the Department of Urology, Kanazawa University Hospital. Pre-operative diagnosis was difficult owing to an atypical imaging finding of a hypovascular renal mass with calcification. A laparoscopic nephroureterectomy was performed, and the surgical specimens showed invasive high-grade urothelial carcinoma within a calyceal diverticulum, and the calcifications were renal stones consisting of 97% calcium oxalate. Urothelial carcinoma in calyceal diverticula is a rare condition, however, a pre-operative definite diagnosis is difficult and a high potential for invasion of the renal parenchyma is suspected in this disease.

    Adrenal cortical carcinomas (ACC) are rare, typically aggressive malignant neoplasms with a reported incidence of 1-2 cases per 1 million population and account for 0.05-0.2 % of all malignancies. The majority of these tumors are functional with approximately 60 % of patients experiencing endocrine symptomatology typically characterized by Cushing's syndrome (40 %) or a mixed hormonal picture of Cushing syndrome seen in association with virilization. Rarely, patients present with a pure hormonal syndrome of feminization or hyperaldosteronism, 6 and 2.5 %, respectively. We report a case of a 76-year-old woman presenting with recently diagnosed hypertension secondary to primary hyperaldosteronism. The patient underwent laparoscopic converted to an open adrenalectomy and a diagnosis of adrenocortical carcinoma (aldosteronoma clinical) was rendered. This case and review of the literature highlight that while rare, aldosterone-secreting adrenal cortical carcinomas may occur. In this case report, we discuss the clinical presentation, pathologic findings, and review the literature for adrenal cortical carcinomas and aldosterone-secreting adrenal cortical carcinomas.

    Ectopic thymic tissue can be present in the thyroid gland and a carcinoma showing thymus-like differentiation (CASTLE) may arise from such tissue. We are reported the case of a 26-year-old man with CASTLE, with cervical subcutaneous nodules relapse, who showed a good response to treatment with surgery, chemotherapy and radiotherapy. The problematic aspect of this case was the diagnosis; only on review were we able to make a final diagnosis. CASTLE is a very rare neoplasm. It is important to differentiate this cancer from others tumors such as primary or metastatic squamous cell carcinoma of the head and neck or squamous cell thyroid carcinoma, because the therapy and prognosis are different. Diagnosis is complicated and requires careful histological analysis (CD5- and P63-positive with presence of Hassall’s corpuscles); unfortunately there is no gold standard treatment so, in this case, we administered a sandwich of chemotherapy and radiotherapy.

    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

    Mesonephric carcinoma of the uterine corpus is an extremely rare malignancy that originates from the mesonephric remnant of the female reproductive tract. There have been no previous reports of mesonephric carcinoma accompanied by a sarcomatous component. The current study presents two cases of uterine corpus mesonephric carcinoma with sarcomatous components that occurred in postmenopausal women. Immunohistochemically, the tumour cells were positive for vimentin and CD10. The tumours of these patients were located in the uterine myometrium; therefore, treatment was similar to that for endometrial cancer. Although the follow-up period was short in the current cases, no metastatic disease was identified in the second case and thus, this may increase clinical knowledge with regard to the biological behavior of these rare malignancies.

    Introduction Soft tissue myoepithelial carcinoma and myoepithelioma are rare entities, part of myoepithelial tumors. They were incorporated into the World Health Organization classification of soft tissue tumors in 2002. Here we present an exceptional case of myoepithelial carcinoma and myoepithelioma association. To the best of our knowledge, such an association has never been reported in the literature. Case presentation We report a case of myoepithelial carcinoma combined with myoepithelioma occurring in the soft tissue of the right forearm of an 84-year-old Arabian man. We describe the clinical, radiological and pathological features dominated by histological polymorphism. We will also describe the proposed histological criteria of malignancy and the major role of immunohistochemistry in positive and differential diagnosis. We finally mention the therapeutic arsenal available. Conclusion Through this work, we report that myoepithelioma of soft tissue can progress to malignant myoepithelioma. PMID:25253093

    Background Papillomatosis presents, most frequently, as multiple lesions of the respiratory tract, which are usually considered benign. Malignant degeneration into squamous cell carcinoma is quite common, although curative approaches vary a lot in modern literature. Case report We report a case of a 66-year-old male patient with the coexistence of multiple squamous cell papilloma and carcinoma in the upper trachea with severe airway obstruction that was diagnosed through bronchoscopy and treated by performing an urgent tracheostomy, followed by concurrent chemotherapy and radiotherapy. There was no evidence of recurrence after a 12-month follow-up period. Conclusion This study underlines the diagnostic and therapeutic value of bronchoscopy as well as multimodality palliative treatment in such cases. To the best of our knowledge, this is the first study to describe an immediate treatment protocol with tracheostomy and concurrent chemotherapy/radiotherapy in a patient with squamous cell tracheal papilloma and carcinoma.

    α-fetoprotein (AFP)-producing esophageal carcinoma is a rare type of esophageal cancer, with its characteristics not yet fully clarified. In the present study, a case of esophageal carcinoma was misdiagnosed as an AFP-producing esophageal carcinoma. The patient was a 50-year-old woman who was referred to Qianfoshan Hospital Affiliated to Shandong University in November 2014 with a 3-month history of progressive dysphagia. A chest computed tomography (CT) scan showed thickening of the wall of the esophagus, corresponding regions of luminal stenosis and massive lymph node swelling around the lesser curvature of the esophagus. A laboratory investigation showed that the serum AFP levels of the patient were elevated to 18.97 ng/ml (normal range <12 ng/ml). These laboratory investigation findings combined with the aforementioned pathological diagnosis supported a diagnosis of AFP-producing esophageal carcinoma. An abdominal ultrasound was performed and a cystic low-density measuring 5×4 mm was identified. No metastases were revealed in the liver. The boundary of the focal low density was clear, which indicated a clinical diagnosis of liver cyst. A radical esophagectomy was performed on December 5, 2014. Microscopically, the tumor was a moderately differentiated squamous cell carcinoma invading the serous layer, with no hepatoid features. Immunohistochemistry showed that the cells were diffusely negative for AFP expression. Histopathological examination revealed the absence of hepatoid features. According to these findings, the tumor was diagnosed as a moderately differentiated squamous cell carcinoma. In the present study, the case of a patient with squamous cell carcinoma that was misdiagnosed as an α-fetoprotein-producing esophageal carcinoma was reported, with a review of the literature.

    A 81-old-woman underwent a transurethral resection of bladder tumor (TURBT) at a nearby hospital in April 2011. The diagnosis was invasive urothelial carcinoma, G3 with a component of bladder small cell carcinoma, T1 or more. She was recommended to visit our hospital for combined modality therapy of bladder cancer, but she refused the treatment for over one year. In May 2012, she came to our hospital with the chief complaint of pain at urination. Cystoscopy revealed non-papillary sessile tumor in the top of the bladder, and CT scan demonstrated the presence of the right obturator lymph nodes swollen up to 1.2 cm in size. The second TURBT was performed and the diagnosis was bladder small cell carcinoma (pT3N2M0) according to urothelial cancer guidelines of the Japanese Urological Association (JUA). Because she strongly refused hospitalization anymore, we started daily oral intake of low dose Tegafur-Uracil (100 mg) for the treatment. After one month, the serum Neuron-Specific Enolase (NSE; tumor maker of small cell cancer) level was elevated to 27.6 ng/ml and the right obturator lymph node was enlarged up to 1.9 cm. Therefore, the Trgafur-Uracil dose was increased to 200 mg daily. After then, the serum NSE level was decreased to 15.5 ng/ml following reduction in size of the obturator lymph nodes with partial response in December 2013. After two years of follow-up period, her regular urine test showed normal findings, and no apparent recurrence was detected on urinary bladder with MRI and Cystoscopy. This is a case of advanced bladder small cell carcinoma significantly improved by oral administration of Tegafur-Uracil 200 mg/day for over 2 years. PMID:26717786

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

    Metaplastic carcinoma of breast (MBC) is a rare and aggressive type of invasive breast cancer. As it encompasses a variety of distinct histopathologic designations, diagnostic challenges abound. We present a case report of metaplastic carcinoma with extensive chondroid differentiation. This case merits presentation because of its rarity and difficulty to diagnose, especially if the tumour is composed mainly of sarcomatous elements. Standard chemotherapy regimes are ineffective against MBC. The prognosis of MBC is poor in comparison to classical invasive breast cancer. Data focusing on MBC is limited due to its rare incidence.

    Cervical cancer is the most frequent type of cancer in women in many developing countries. Squamous cell carcinoma of the cervix spreads principally by lymphatics and less commonly through blood vessels. The most frequent sites for those who develop distant metastasis include lungs (21%), lumbar and thoracic spine (16%), and para-aortic lymph nodes (7%). Metastasis to the kidney is extremely rare with <10 previously reported cases. We report a case of renal metastasis from squamous cell carcinoma of the cervix detected in end-stage kidney due to hydronephrosis. PMID:27499599

    Bony metastases develop in 30% of all the cancers, but out of which only 1% to 3% occurs in the hand. Lung is the most common site for acrometastasis, followed by breast and renal cell cancer. Metastases to the digits are with non-specific presentation. We reported a case of 79-year-old male patient with initial presentation of swelling over left index finger, which was found to be squamous cell carcinoma of finger on histopathological examination. He was subsequently diagnosed as a case of squamous cell carcinoma of lung with acrometastasis. PMID:27504389

    Oncocytic carcinoma (OC) of the submandibular gland is extremely rare. A 76-year-old man complained of a painless tumor of the right neck. Ultrasonography demonstrated swelling in the lymph nodes of the neck, and fine-needle aspiration cytology of a node showed metastatic carcinoma with oncocytic features. Radical surgery revealed infiltrating carcinoma of the right submandibular gland with lymph node metastases (19/23). Tumor cells showed less atypia and had abundant eosinophilic cytoplasm, which stained deep blue with phosphotungstic acid-hematoxylin stain. The cells were immunohistochemically positive for cytokeratin 7 but negative for p63 and SOX10. We diagnosed the tumor as OC. Chemoradiotherapy was performed after surgery. The patient showed no sign of recurrence until 42 months after the operation, when lymph node swelling was detected in the mediastinum by computed tomography scanning. With no further treatment, the patient is alive with lymph node swellings in the mediastinum and pulmonary hilum 80 months after surgery. PMID:26699942

    In the present study, the case of a 51-year-old female with a metastatic tumor in the left kidney originating from cervical carcinoma, is reported. The patient had undergone chemoradiotherapy for stage IIB squamous-cell carcinoma of the uterine cervix 3 years earlier. Computed tomography (CT) identified low-density left renal nodules, which were diagnosed post-operatively as renal cysts during the follow-up conducted 2 years later. The next year, the patient was admitted to the Hunan Provincial Tumor Hospital (The Affiliated Tumor Hospital of Xiangya Medical College, Central South University, Changsha, Hunan, China) with a fever of unknown origin, left-sided flank pain and hematuria. CT examination detected irregular low-density nodules in the left kidney and heterogeneous enhancement on enhanced CT. Subsequently, the patient was subjected to a nephrectomy. Post-surgical analysis of subsequent biopsies indicated kidney tumor metastasis originating from cervical carcinoma. Renal metastases are rare in patients with cervical carcinoma. The present study reported a case of renal metastasis originating from cervical carcinoma and also reviewed previous case reports on patients presenting with this unusual type of cancer.

    Mucoepidermoid carcinoma of the lung is exceedingly rare. Our case involves a 58-year-old male who presented with shortness of breath, dysphagia, and weight loss. He denied ever smoking. Chest x-ray revealed trapped lung, and CT demonstrated a right bronchial mass. Diagnosis of lung carcinoma was made by bronchoscopic FNA biopsy. EGFR mutation was negative. Staging workup demonstrated evidence of advanced disease. Performance status was good, and it was decided to start chemotherapy and radiation for palliation. Lung carcinomas often present as an obstructing hilar mass. There are different histological grades that affect progression and survival. Though uncommon, metastatic spread has been previously reported. Studies have investigated the possible role of tyrosine kinase inhibitors in both EGFR-mutated and non-mutated cases. Unfortunately, there has been little consensus as to which therapies are most beneficial. PMID:25887880

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

    Metastatic cancers of the pancreas are rare, accounting for approximately 2–4% of all pancreatic malignancies. Renal cell carcinoma is the most common solid tumor that metastasizes to the pancreas. Here, we present a case of uterine cervical carcinoma metastasizing to the pancreas and review the literature regarding this rare event. A 44-year-old woman with a uterine cervical tumor had undergone radical hysterectomy and had been diagnosed pathologically with stage Ib mixed adenoneuroendocrine carcinoma in 2004. She underwent concurrent radiotherapy and chemotherapy postoperatively. Pulmonary metastases subsequently appeared in 2008 and 2011, and she underwent complete resection of the lung tumors by video-assisted thoracic surgery. Although she was followed up without any treatment and with no other recurrences, positron emission tomography revealed an area of abnormal uptake within the pancreatic body in 2012. Enhanced computed tomography demonstrated a 20-mm lesion in the pancreatic body and upstream pancreatic duct dilatation. Endoscopic ultrasonography-guided fine needle aspiration was performed and pathological examination suggested neuroendocrine carcinoma (NEC). On the basis of these results and the patient's oncological background, lesions in the pancreatic body were diagnosed as secondary metastasis from the cervical carcinoma that had been treated 8 years earlier. No other distant metastases were visualized, and the patient subsequently underwent middle pancreatectomy. Pathological examination showed NEC consistent with pancreatic metastasis from the uterine cervical carcinoma. The patient has survived 7 months since the middle pancreatectomy without any signs of local recurrence or other metastatic lesions. PMID:23741220

    Lung carcinoma is the commonest major malignancy in men in the United States and its incidence is increasing rapidly in women. It is estimated that there will have been 117,000 new cases and 101,300 deaths in 1980. The 2286 patients with lung carcinoma admitted to the Hospital of the University of Mississippi from 1955 to 1980 were reviewed by decades of chronology and of life, with respect to age, cell type, sex and racial incidence. The greatest age incidence was in the sixth and seventh decades; cell types overall were epidermoid (45% of the patients), adenocarcinoma (12% of the patients), small (oat) cell (21% of the patients), and others (22% of the patients). There was a steady increase in the incidence of disease in females, adjusted for total hospital admissions, and a less certain increase among black patients. Twenty-eight per cent of 250 patients with small cell carcinoma so studied exhibited some feature of the paraneoplastic or paraendocrine syndromes. In 41 patients with small cell carcinoma treated with multiple drug chemotherapy, there was an overall response rate of 50% and an additional "stable disease" rate of 28%. Mean survival period in this group was 52 weeks, compared with 12 weeks in patients whose diseases went untreated. Clearly, definite progress is being made, not only in our knowledge of the biology of lung carcinoma, in general, but in the treatment of small cell carcinoma in particular. Images Fig. 4.

    Squamous cell carcinoma of the temporal bone and external auditory canal is a rare tumor with a reported incidence of between 1 to 6 cases per million population per year. Because squamous cell carcinoma of the temporal bone and auditory canal is so rare, developing an adequate tumor staging system and treatment has been difficult. We present a case of squamous cell carcinoma of the external auditory canal in 65-year-old Hispanic female who presented with a 6-month history of right ear pain, 3-month history of serosanguineous right ear drainage, and symptoms of facial paralysis. Due to the extensive spread of her tumor into the middle ear at the time of diagnosis, her tumor was deemed unresectable and she received palliative chemotherapy and radiation therapy and was sent to Alice Hospice and died several weeks later.

    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

    Sinonasal neoplasms are rare and exceptional site for metastatic tumours and comprising <3 % of all malignant aerodigestive tumours and <1 % of all malignancies. Renal cell carcinoma is known to metastasise to the most unusual sites, the sinonasal region being one of them. We here by present a case of 60 year old male patient who presented with epistaxis and nasal obstruction. Clinical examination and CT scan revealed a tumour in the right nasal cavity and maxillary sinus. The presence of primary renal cell carcinoma was recognized only after surgical removal of metastatic tumour. Very few reports have been presented in literature of metastatic renal cell carcinoma in the sinonasal region. We present this case to document its occurrence; highlight the rarity, presentation and difficulties in diagnosis and treatment along with review of literature. PMID:27508143

    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

    It is widely known that echinoderm microtubule-associated protein-like 4 anaplastic lymphoma kinase (EML4-ALK) rearrangement mostly occurs in the adenocarcinoma subtype of non-small-cell lung cancer (NSCLC). Patients with squamous cell carcinoma harboring the ALK rearrangement are extremely rare. This is a case report of a squamous cell carcinoma patient with EML4-ALK rearrangement. An elderly man with a heavy smoking history presented with a mass lesion in the right main bronchus. Bronchoscopic biopsy of the tumor confirmed a diagnosis of squamous cell carcinoma, and it was proven to harbor ALK rearrangement, based on fluorescence in situ hybridization, but not epidermal growth factor receptor mutations. The patient underwent radiation therapy, with a markedly favorable response. ALK-targeted treatment may be a viable option if disease progression occurs in such a case in the future. PMID:27330767

    Complete dissection of tracheobronchial adenoid cystic carcinoma (TACC) by surgery alone is sometimes difficult and has a greater propensity than tracheobronchial mucoepidermoid carcinoma (TMEC) for its surgical margin to become positive. In addition, TACC is more likely to present distant metastases than TMEC. Considering these facts, TACC and TMEC should be differentiated based on histopathological examination of biopsy specimens. Herein, we present a case of 54-year-old woman with a tumor in the right main bronchus, whose biopsy specimen was difficult to diagnose as TACC or TMEC. The specimen from the rounded protrusion of the tumor showed squamous differentiation, along with the presence of glandular and basaloid cells, making morphological examination alone ineffective in rendering a definite diagnosis. Thus, the addition of immunohistochemical analysis, αSMA and CD43 expression in basaloid cells and c-kit expression in glandular cells, was useful for accurately diagnosing TACC in this case. The squamous component was considered to be neoplastic because of its increased expression of cyclin D1 and overexpression of p16. The surgically resected specimen contained typical morphology of ACC, and the diagnosis of TACC was definitely confirmed. PMID:26191305

    A 75-year-old man visited our hospital complaining of a foul smelling, painful swelling of the glans of the penis. Physical examination showed a true phimosis and a huge solid mass on the glans under the foreskin. After postectomy and penile tumor biopsy, we performed partial penectomy. Histologically, the tumor was composed of atypical spindle cells arranged in an epithelioid pattern and stained positive for both epithelial and mesenchymal markers. Therefore we diagnosed the tumor as sarcomatoid carcinoma of the penis. One month after surgery, advanced gastric cancer was discovered. Thereafter, cancer rapidly spread throughout the whole body, and he died six months postoperatively. PMID:26153055

    A case of synchronous carcinoma of the accessory mammary gland and primary breast lymphoma with subsequent rectal carcinoma has not been reported previously. We present a very rare case of primary non-Hodgkin lymphoma of the left breast diagnosed simultaneously with invasive lobular carcinoma of the left axillary accessory mammary gland and rectal adenocarcinoma. An 82-year-old Japanese woman presented with two palpable masses on the left chest wall. She was given a diagnosis of suspected breast malignant tumor and axillary accessory mammary gland. She underwent excision of the axillary accessory mammary gland and left mastectomy with axillary lymph node dissection. Histopathological examination revealed diffuse large B-cell lymphoma of the breast and invasive lobular carcinoma of the axillary accessory mammary gland with lymph nodes metastasis. Three months after the surgery, primary rectal adenocarcinoma was also detected by F-18 fluorodeoxyglucose positron emission tomography. Hartmann's operation was performed, since which time the patient has been doing well. PMID:25217973

    The extraovarian peritoneal serous papillary carcinoma (EPSPC) is a multicentric peritoneal tumor with minimal or absent involvement of the ovaries. The actual treatment regimen consists of a cytoreductive surgery followed by a combination chemotherapy. Few studies have compared outcome of EPSPC to papillary serous ovarian cancer (PSOC). Several authors have documented similar clinical behavior between EPSPC and PSOC, but this finding has not been universal. A 64-year-old female patient with symptomatic gall stone disease underwent elective laparoscopic cholecystectomy. Unexpectedly we found some uncommon small nodular structures on the serosa of the right colon. The histological findings suggested a poorly differentiated peritoneal serous papillary carcinoma. Biopsies of both ovaries showed no signs of tumor infiltration and the diagnosis of EPSPC was established. After surgery, a combination chemotherapeutic regimen with carboplatin and cyclophosphamid was given. Laparoscopic reassessment 7 months after the first procedure showed no tumor. 3 identical cycles completed chemotherapy. Normal ovaries and no other tumor sites were found in a final laparoscopic look after 11 months. PMID:10073126

    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.

    Matrix-producing carcinoma (MPC) of the breast is an extremely rare variant of metaplastic breast carcinoma that contains a mixture of epithelial and mesenchymal elements. As overt carcinoma with direct transition to a cartilaginous and/or osseous stromal matrix cells, MPC is of no spindle cells between those two elements. This is the case of a 43 year-old female patient with MPC which coexisted with microglandular adenosis (MGA), atypical MGA (AMGA) and carcinoma in situ arising in MGA (MGACA in situ). MGA is a rare, infiltrative, benign lesion of the breast with an indolent clinical course. Histological evidence of carcinoma arising from MGA has previously been documented. MPC arising in MGA is an extremely rare subtype of breast carcinoma and has been seldom detailed described in the previous studies. This report highlights one such case with cytomorphological and histopathological correlation, along with a review of pertinent literature and differential diagnosis. PMID:26339435

    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. PMID:27237368

    Merkel cell carcinoma (MCC) is an aggressive neuroendocrine carcinoma that only rarely regresses spontaneously. Since little is known about the immunological mechanisms involved in the spontaneous regression of MCC, we describe a case of MCC with spontaneous regression and employed immunohistochemical staining for cytotoxic and immunosuppressive molecules to investigate possible mechanisms involved in the spontaneous regression of MCC. Interestingly, compared to conventional MCC, tumor-infiltrating lymphocytes in MCC with spontaneous regression contained higher numbers of CD8+ cells and granulysin-bearing cells and lower numbers of CD206+ cells. Our present study suggests one of the possible reasons for the spontaneous regression of MCC. PMID:27293394

    We herein report the case of a 61-year-old Japanese male with localized pleural metastases of renal cell carcinoma. The patient was admitted to our hospital because of dyspnea on exertion and left-sided pleural effusion. He had undergone right radical nephrectomy 10 years previously. Contrast-enhanced whole-body computed tomography revealed scattered nodular thickening of the left pleura with contrast enhancement and left-sided pleural effusion. Thoracoscopy performed under local anesthesia was applied to obtain a biopsy of the pleural nodules, and the specimen was consequently diagnosed as exhibiting pleural metastasis of renal cell carcinoma, clear cell type.

    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

    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. PMID:26790674

    A 58-year-old woman presented to our hospital with a huge hepatic mass. A CT scan showed an enhanced mass lesion on the fundus of the gallbladder and an enhanced mass ring on the gallbladder bed. 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.

    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.

    Background Coexistence of splenic marginal zone lymphoma with hepatocellular carcinoma is rare. Although some reports have suggested the possible pathogenic role of HBV, HCV, chronic and persistent antigenic stimulation in lymphoma, their role in causing lymphomas is still unclear. Case presentation We describe a hepatocellular carcinoma with concomitant splenic marginal zone lymphoma in a 64-year-old Chinese man with cirrhosis. Serum hepatitis B virus surface antigen was positive and antihepatitis C virus antibody was negative. The resected liver mass measuring 4 × 3 × 3 cm was grey and soft with a small area of bleeding, necrosis and intact capsule. Cut surface of the spleen was red-purple and had a diffuse reticulonodular appearance indicative of prominent white pulp. On histologic sections, the liver mass was well and moderately differentiated hepatocellular carcinoma, and the splenic tumor was a specific low-grade small B-cell lymphoma. Immunohistochemical staining and gene rearrangement studies supported that the splenic tumor represents a clonal B-cell lymphoma. Therefore, the diagnosis of SMZL was made from the splenic specimen. Conclusion To our knowledge, this is the second case report describing coexistence of hepatocellular carcinoma and splenic marginal zone lymphoma in the course of chronic HBV infection. However, we cannot assert at present that hepatitis B virus is directly involved in splenic lymphomagenesis until more information is collected from more cases in the future. PMID:17284308

    Salivary duct carcinoma (SDC) is a rare and aggressive parotid malignancy that most commonly affects males in the fifth and sixth decades of life. Histopathology specimens obtained from SDC patients demonstrate a resemblance to ductal carcinoma of the breast. Therefore, to distinguish SDC from breast ductal carcinoma, several immunohistochemical markers exist that may enable surgeons to make an accurate diagnosis. In this study, the case of a 54-year-old male with salivary duct carcinoma of the right parotid gland is presented. The results of the present case study revealed that the SDC sample was positive for the expression of human epidermal growth factor 2 (Her-2), cytokeratin (CK) 8/CK 18, p63, high molecular weight CK and calponin, and negative for expression of the estrogen receptor and progesterone receptor. Based on the result, an ipsilateral selective neck dissection followed by adjuvant post-operative radiation therapy was suitable at the primary treatment stage. At one year of follow-up, the patient was alive and free of recurrence. In advanced cases of SDC, treatment with anti-HER-2 monoclonal antibodies, such as trastuzumab, is recommended. PMID:25435994

    The present study reports a rare case of a renal clear cell carcinoma with thyroid and parotid metastases. A 56-year-old female, with a painless, right preauricular mass present for 6 months was referred to Renji Hospital (Shanghai, China). Physical examination revealed a mass of 3×3 cm, which was smooth, firm, immobile and non-tender. There was no accompanying facial weakness. Parotid ultrasonography revealed a hypoechoic mass within the right parotid gland, which was potentially a parotid mixed tumor. In July 2011, the patient underwent a superficial parotidectomy with preservation of the facial nerve. Pathology confirmed as right parotid clear cell carcinoma (metastasis). The patient's relevant medical history included a right radical nephrectomy for renal clear cell carcinoma (clinical stage III) in 2004. Additionally, in 2009, the patient underwent a resection of thyroid metastatic renal cell carcinoma. To the best of our knowledge, no similar case has previously been reported in English-language literature. The present study discusses a case report, and investigates the clinical features and treatment strategy. PMID:26622899

    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

    Skull base metastasis from differentiated thyroid carcinoma, including papillary and follicular thyroid carcinoma, is a rare manifestation. Herein, we present three cases of skull base metastasis of papillary thyroid carcinoma. The mean age of the patients was 68.6 (65–74) years, and the mean interval between initial diagnosis and skull base metastasis was 56.3 (28–89) months. Cranial nerve palsies were seen in all patients. Intensity modulated radiation therapy to deliver 6,000–6,600 cGy to the skull base metastasis was given to all patients, in addition to partial resection in one patient. At the time of last follow-up, all skull base metastases were well controlled. PMID:26203287

    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. PMID:18637444

    We describe here a female patient who presented with a breast mass and giant abdominal mass. Fine needle aspiration cytology of the breast mass and histological examination after modified radical mastectomy confirmed metaplastic carcinoma of the breast. The epithelial components were formed by infiltrating ductal carcinoma with poor differentiation, and the sarcomatous components were formed by fibrosarcoma and osteosarcoma. Histological examination of the abdominal mass confirmed ovarian teratoma. The patient underwent modified radical mastectomy of the right breast and laparoscopic excision of the abdominal mass in the lower right quadrant. Having underwent six courses of chemotherapy, the patient is now in her tenth month after surgery and under follow-up, and she has no relapsed disease. These two diseases have never seen in one patient before. The case we report here provides some new data for research and clinical experience and it may also provide a new insight into the relationship between metaplastic breast carcinoma and ovarian teratoma.

    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

    We report a case of anal canal cancer with inguinal lymph node metastasis treated with laparoscopic abdominoperineal resection combined with inguinal lymph node dissection. A 52-year-old woman was diagnosed with anal squamous carcinoma after excision of an anal canal tumor. Further examination revealed right inguinal lymph node metastasis. Chemoradiotherapy was administered but was discontinued because of serious adverse events. We therefore performed laparoscopic abdominoperineal resection combined with inguinal lymph node dissection. The pathological findings revealed residual squamous cell carcinoma at the lymphatic vessels in the rectal wall and lymph nodes, including the right inguinal region. Therapeutic effect of Grade 1a was achieved in spite of interruption of the chemoradiotherapy. She was discharged 17 days after the operation, and no recurrence was observed for 11 months. Radical resection was performed for the anal canal squamous cell carcinoma with the metastasis to the right inguinal lymph node, even after interruption of the chemoradiotherapy. PMID:26805350

    Breast cancer is the most commonly diagnosed cancer among American women and is also the most common internal malignancy to metastasize to the skin. Rarely, cutaneous metastases represent the first indication of breast carcinoma, putting dermatologists in an instrumental position to make the diagnosis of breast carcinoma. We report the case of a 71-year-old woman with a 10-year history of a slowly-enlarging, indurated plaque in the right axilla. Review of symptoms was significant only for occasional numbness and tingling that extended from the right axilla to the right hand. Biopsy revealed cells infiltrating in a single-file between the collagen bundles in the dermis and subcutis and immunohistochemical staining consistent with a diagnosis of invasive lobular carcinoma. Subsequent work up revealed a primary breast lesion and extensive bony metastases. PMID:27617728

    We report a rare case of black thyroid accompanied by papillary carcinoma in a patient with an extended history of minocycline treatment. A 78-year-old man was referred to our outpatient clinic with swelling in his neck. He had been taking minocycline for the previous 2 years and 7 months to treat chronic perianal pyoderma. Neck ultrasonography and computed tomography demonstrated a 3.5 × 3.7 × 5.0-cm nodule in the left thyroid lobe, and fine-needle aspiration cytology identified it as a papillary carcinoma. The patient underwent a total thyroidectomy and neck dissection. During the procedure, a distinct black discoloration of the thyroid parenchyma was observed. Histopathology confirmed both the black thyroid and the papillary carcinoma. Based on the thyroid gland's discoloration and the history of minocycline use, the patient was diagnosed with minocycline-induced black thyroid. He was symptom-free 20 months after surgery.

    2016-01-01

    Mixed adenoneuroendocrine carcinomas (MANECs) are rare biphasic tumour types, which are morphologically recognisable as both gland-forming and neuroendocrine neoplasms. Within the gastrointestinal tract, MANECs occur predominantly in the stomach or colorectum. The present study described a case of a MANEC originating from the ampullary region. The patient presented with widespread metastatic disease. Biopsy samples obtained from the ampullary primary tumour disclosed a complex lesion with adenocarcinoma and neuroendocrine small cell carcinoma components, positive for the intestinal transcription factor caudal type homeobox-2 and for neuroendocrine markers, including chromogranin A, synaptophysin, cluster of differentiation 56/neural cell adhesion molecule. By contrast, biopsy samples obtained from metastatic tissue revealed pure neuroendocrine carcinoma. As exemplified by this true mixed tumour, tumour heterogeneity evolves as the major challenge in oncology today, with potentially severe implications for the choice of chemotherapy. The assessment of metastatic sites may render valuable diagnostic information that is crucial for clinical decision-making and patient management. PMID:27330774

    Primary squamous cell carcinoma is a well known malignancy of the skin and other organs composed of squamous cells, which are normally not found inside the breast. Therefore, a primary squamous cell carcinoma of the breast is an exceedingly uncommon phenomen and the management of this type of disease is still unclear. We report the case of a 43-year-old Moroccan woman, without significant medical history, presented an infected mass of 9 cm in the left breast associated with ipsilateral axillary lymphadenopathy. The mass's surgical biopsy revealed a triple negative primary squamous cell carcinoma of the breast. She underwent a neoadjuvant chemotherapy using 5 Fluoro-Uracil and platinum. After three courses, she presented a contralateral breast progression and apparition of metastasis at D10. She received one course of a palliative chemotherapy based on weekly paclitaxel stopped because of her peformans status deterioration. She died 7 months after her admission.

    The orbit is a frequent site of metastasis, particularly from the breast, prostate gland and the lung. Carcinoma of the cervix metastasizing to the orbit is rare. We report a 27-year-old woman with Stage II B cervical cancer who presented with progressive painless protrusion of the left eye of one month duration associated with diplopia. Histology of the orbital mass was similar to that of the cervical cancer and reported as squamous cell carcinoma. She received palliative radiation to the left orbit 30 Gy in 10 fractions along with chemotherapy (Paclitaxel and Carboplatin). This resulted in regression of the proptosis. We review published literature of cases of carcinoma of the uterine cervix with metastasis to the orbit. PMID:26894102

    We describe a two-stage surgical approach in a patient with cardiac dysfunction and hemodynamic compromise resulting from a massive and compressive mediastinal bronchogenic cyst. To drain this cyst, video-assisted mediastinoscopy was performed as an emergency procedure, which immediately improved the patient's cardiac function. Five days later and under video thoracoscopy, resection of the cyst margins was impossible because the cyst was tightly adherent to the left atrium. We performed deroofing of this cyst through a right thoracotomy. The patient had an uncomplicated postoperative recovery, and no recurrence was observed at the long-term follow-up visit.

    One hundred and seven cases of oral verrucous carcinoma treated primarily with radiotherapy at Kasturba Hospital, Manipal, India between 1977 and 1987 were analysed concerning location within the oral cavity, clinical extent, and effectiveness of radiotherapy. The most common site was the buccal mucosa followed by the buccogingival sulcus. Only 13.2% of the patients presented with T1 or T2 tumours and 32.7% had clinically negative nodes. Biopsy had to be repeated more than once in 22 patients to get confirmation of invasive carcinoma. The 5-year survival rate was 35% for stage III and 26% for stage IV. The treatment results with radiotherapy were comparable with those for ordinary squamous cell carcinoma of the oral cavity. It is felt that the treatment policy for verrucous carcinoma can be the same as for ordinary squamous cell carcinoma. In order to prevent delay in diagnosis and treatment, proper cooperation between the treating oncologist and the pathologist is essential. PMID:1586504

    The rupture of a metastatic mixed adenoneuroendocrine carcinoma (MANEC) has not been previously reported, although the neuroendocrine cell carcinoma is often associated with a high incidence of hepatic metastases. The patient was a 39-year-old male who presented with upper abdominal pain over 3 months. Computed tomography showed multiple tumors in both hepatic lobes, while lower gastrointestinal endoscopy revealed a tumor in the transverse colon. Histopathologic examination of the tumor revealed it to be a neuroendocrine cell carcinoma. After the resection of the primary tumor, hepatic metastases rapidly increased, and one of them in the left lateral segment was ruptured with significant hemorrhage. The rupture led us to undertake the emergency operation to stop the bleeding. Histology showed a high-grade large-cell neuroendocrine carcinoma associated with moderately differentiated tubular adenocarcinoma. The Ki-67 labeling index was 80% (G3). The diagnosis was mixed adenoneuroendocrine carcinoma according to the 2010 World Health Organization guidelines. Hepatic arterial infusion chemotherapy, systemic chemotherapy, and transcatheter arterial chemoembolization did not decrease the tumor progress, and the patient died on postoperative day 110. Reporting this highly malignant case, I hope all doctors can be interested in MANEC. PMID:24444267

The diagnosis was mixed adenoneuroendocrine carcinoma according to the 2010 World Health Organization guidelines. Hepatic arterial infusion chemotherapy, systemic chemotherapy, and transcatheter arterial chemoembolization did not decrease the tumor progress, and the patient died on postoperative day 110. Reporting this highly malignant case, I hope all doctors can be interested in MANEC. PMID:24444267

    Hepatocellular carcinoma with prominent fatty change is rare, and to date only a few cases have been reported. In this article, we present a 57-yearold woman who underwent a liver transplant for hepatocellular carcinoma. Ten months after liver transplant, she presented with a persistent cough. Computed tomography of the chest was performed, revealing a solid lung mass that measured 1 × 0.9 cm in the right inferior lobe. Right inferior lobectomy was performed, and the final diagnosis was noted as hepatocellular carcinoma with prominent fatty change. Fatty change was extensive in the tumor; therefore, lipoid pneumonia was the first condition that was considered in the differential diagnosis during examination of the lobectomy material. For the differential diagnosis, the immunohistochemistry panel was studied to show the hepatocellular nature of the tumor. Although metastasis of hepatocellular carcinoma to the lungs is expected, hepatocellular carcinoma with prominent fatty change can cause diagnostic difficulties, such as lipoid pneumonia, especially in small lung biopsies.

    Background: Poorly differentiated thyroid carcinomas (PDTCs) lie, both morphologically and behaviorally, between well-differentiated and undifferentiated carcinomas. Metastasis of poorly differentiated thyroid carcinoma to the intranasal cavity has not been reported previously in the literature. Case Report: A 48-year-old male patient presented with massive epistaxis and nasal obstruction. On nasal examination, a bleeding, vascular mass was seen filling the left nasal cavity. The histopathological report of the nasal mass was well-differentiated thyroid carcinoma metastasis. Whole body scintigraphy, ultrasonography and positron emission tomography were done to rule out other possible metastases in the body and determine the origin of the tumor, which was identified as the left lobe of the thyroid gland, and there were multiple metastases involving the lung, sacroiliac area, and left humerus. Histopathological examination of a thyroidectomy specimen revealed PDTC consisting of insular, follicular, and papillary components. Postoperatively, the patient received radioactive iodine ablation therapy (iodine-131) and a course of external beam radiation therapy to the sacroiliac area and other metastatic regions. No recurrences were observed in a follow-up period of 5 years after surgery. Conclusion: The metastasis of differentiated thyroid carcinoma as a component of PDTC to the intranasal cavity has not been reported before. It is interesting that the well-differentiated component of the tumor was metastasized in our patient. Due to the aggressiveness of PDTC and the poor survival rates in patients who undergo surgery alone, a multidisciplinary treatment approach is required. PMID:26185723

    Purpose: Mucoepidermoid carcinoma is a rare variant of squamous cell carcinoma of the conjunctiva. It appears more frequently in the elderly, it is more aggressive than squamous cell carcinoma, and it has a higher recurrence rate and higher incidence of intraocular and orbital invasion. Methods: We report a case of a 74-year-old man who presented to the Emergency Department with a one month history of painful red left eye. Results: The patient presented with visual acuity was 10/10 in both eyes and a conjunctiva tumor on the bulbar conjunctiva of left eye. The UBM revealed a thickening of the conjunctiva-sclera complex with no signs of intraocular invasion. A biopsy was performed and the diagnosis was of mucoepidermoid carcinoma. Two local excisions with adjuvant cryotherapy and mitomycin C aplication were carried out in a period of 6 months. After 9 months of follow-up there has not been any sign of recurrence. Conclusions: The early diagnosis and treatment of carcinoma is essential not only to prevent the intraocular spread and preserve visual function but also to prevent local or systemic recurrence and dissemination.

    Malignant melanoma can be successfully treated when it is identified in its early stages, but the disease is associated with a poor prognosis when it is detected in an advanced stage. Papillary thyroid carcinoma is a thyroid cancer that has a good prognosis. The present study reports a rare case of malignant melanoma and papillary thyroid carcinoma that were diagnosed concurrently and treated simultaneously. The present patient was a 37-year-old male, in whom examination of a skin biopsy that was obtained from a lesion in the right retroauricular region revealed the lesion to be consistent with malignant melanoma. The patient underwent radical neck dissection upon the detection of malignant melanoma metastasis to the sentinel lymph node. Metastases of papillary thyroid carcinoma were detected in four out of 38 lymph nodes. The patient was then diagnosed with papillary thyroid carcinoma and underwent total thyroidectomy. The patient was administered with high-dose followed by moderate-dose interferon-α therapy for the treatment of malignant melanoma. The patient also received concurrent radioactive iodine therapy for the treatment of papillary thyroid carcinoma, at the same time as the interferon therapy. The two primary tumors of the patient were treated successfully. During therapy, no serious side-effects were observed, with the exception of fever caused by high-dose interferon therapy. Malignant melanoma and papillary thyroid carcinoma may occur concurrently, although this is rarely observed. The present study reports a rare case that demonstrates that the two tumors can be successfully treated simultaneously. PMID:25436010

    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

    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

    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. PMID:26645012

    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

  17. Lung squamous cell carcinoma metastasizing to the nasopharynx following bronchoscopy intervention therapies: a case report

    PubMed Central

    2014-01-01

    Metastatic carcinoma to the nasopharynx is extremely rare, and few cases have been reported in the literature. In the present report, we describe the case of a patient with a mass in the nasopharynx found by bronchoscopy. Our patient was a 61-year-old man receiving multiple bronchoscopy intervention therapies for advanced lung squamous cell carcinoma (SCC), which was histopathologically confirmed. The SCC metastasized to the nasopharynx following the bronchoscopy intervention therapies. The lesion was considered metastatic from lung cancer on the basis of clinical and histological clues. The exact mechanism of lung cancer metastasis to the nasopharynx in this case remains unclear because either implantation or hematogenous and lymphatic spread is possible. A thorough head and neck examination should be undertaken during bronchoscopic evaluation, especially in patients receiving bronchoscopy intervention therapies. The early detection of a silent nasopharyngeal metastasis is important to choosing from among the multiple treatment options available. PMID:24673971

    Primary kidney parenchyma squamous cell carcinoma is extremely rare, and this is the forth case to be reported. In the present study, a case of a 61-year old man is discussed. The man presented with recurrent lumbago, gross hematuria for nearly 2 months, and suspicious inflammatory kidney diseases on contrast-enhanced computed tomography (CT) and fludeoxyglucose-positron emission tomography (FDG-PET)/CT, but a tumor can not be excluded completely prior to surgery. Finally, radical nephrectomy was performed, and histological analysis determined that the diagnosis was kidney parenchyma squamous cell carcinoma with inflammation invasion. The present case highlights the potential confusion of preoperative diagnosis of renal tumor with inflammation, and introduces the potential role of FDG-PET in its diagnosis and survival evaluation in renal malignancies.

    Endometrial serous carcinomas are very clinically aggressive, which constitutes 40% of all deaths and recurrences associated with endometrial cancer. Small-cell carcinoma of the endometrium is relatively rare but aggressive, and often presents a component of endometrioid carcinoma, and is not generally associated with serous carcinoma. Herein, we report a case of 74-year-old African-American female, who presented with intermittent post-menopausal bleeding for > 1-month. She underwent robotic-assisted laparoscopic hysterectomy, bilateral salpingo-oophorectomy, sentinel lymph node mapping, and pelvic-and-aortic lymphadenectomy. Final pathology was consistent with serous carcinoma of the endometrium in combination with neuroendocrine small-cell carcinoma. This extremely rare combination of tumors presents a challenge for treatment. The mainstay of treatment seems to be surgery followed by chemotherapy ± radiation therapy. To our knowledge, it represents an under-reported area of gynecological medicine. PMID:27508271

    Patient: Male, 74 Final Diagnosis: Spindle cell carcinoma of the lung Symptoms: — Medication: Pemetrexed • carboplatin Clinical Procedure: Biopsy and autopsy Specialty: Oncology Objective: Rare disease Background: Spindle cell carcinoma (SPCC) of the lung is a subset of sarcomatoid carcinoma. Its clinical features are unclear because of its rarity. Here, we report an autopsy case of SPCC and review CT findings and chemotherapeutic regimens based on previous reports of this disease. To our knowledge, this is the first reported case of pemetrexed used to treat SPCC. Case Report: A 74-year-old Japanese male presented with dyspnea and contrast-enhanced computed tomography (CT) showed abundant left pleural effusion and a mass in lower lobe of the left lung. By the tumor biopsy, he was diagnosed for SPCC of the lung, cT3N0M1a, stage IV. The tumor was resistant to chemotherapy with carboplatin and pemetrexed, and rapidly progressed. Autopsy revealed abundant hemorrhage within the tumor, which apparently reflects a low-density area in CT. Conclusions: Present case and the accumulation of cases indicate that low-density areas in CT and rapid tumor progression may be common SPCC findings. PMID:26558362

    We present a case of a 63-year-old man who was admitted to another hospital because of abdominal distension and body weight loss. Gastric endoscopy revealed a type III tumor at the posterior wall of the upper gastric body. The tumor had invaded into the esophagogastric junction. On the basis of the pathology of the biopsy specimen, the tumor was diagnosed as neuroendocrine carcinoma of the esophagogastric junction. Computed tomography (CT) scans showed regional lymph node swelling. Cisplatin( CDDP) +irinotecan( CPT-11) therapy was selected and administered to the patient. After 2 courses, the patient received S-1+CDDP. He was considered to have stable disease. We performed partial resection of the lower esophagus, total gastrectomy, splenectomy, and cholecystectomy. On pathology, the tumor was immunohistochemically positive for chromogranin A, AE1/AE3, neural cell adhesion molecule (NCAM), neuron-specific enolase (NSE), and p53. The Ki-67 index was 80%. The tumor was diagnosed as a mixed adenoneuroendocrine carcinoma (MANEC) of the esophagogastric junction. The patient was treated with S-1 and CDDP. Neuroendocrine cell carcinoma of the esophagogastric junction is rare and usually has a very poor prognosis. We herein report a case of mixed adenoneuroendocrine carcinoma of the esophagogastric junction that was curatively resected and resulted in patient survival without recurrence. PMID:24394092

    Introduction It is extremely rare for gallbladder carcinoma to produce granulocyte-colony stimulating factor (G-CSF) and such tumors have a poor prognosis. Presentation of case A 67-year-old man was admitted with continuous fever. Laboratory tests showed a leukocyte count of 27,980/μL, serum C-reactive protein (CRP) of 9.2 mg/dL and serum G-CSF of 225 pg/mL. Imaging revealed an irregular gallbladder mass about 90 mm in diameter with peripheral enhancement that also involved the liver and transverse colon. G-CSF producing gallbladder carcinoma was diagnosed. We performed cholecystectomy, partial resection of segments 4 and 5 of the liver, partial resection of the transverse colon, and gastrostomy. Histopathological examination showed gallbladder carcinoma (pT3, pN0, M0, G2, and pStage IIIA by the UICC classification, version 7). On immunohistochemical staining, tumor cells were positive for G-CSF. The leukocyte count was normalized postoperatively and fever subsided immediately after surgery. Two months later, the leukocyte count rose to 56,820/μL and metastases to the liver and lymph nodes were detected by CT. Chemotherapy (gemcitabine plus cisplatin) was started and the leukocyte count was normalized after the first course. The patient has continued chemotherapy and has survived for 16 months postoperatively. Discussion G-CSF producing gallbladder carcinoma has a poor prognosis and most patients die within 12 months of starting therapy. It is rare for patients with recurrence to survive for 16 months after surgery, as in the present case. Conclusion Multidisciplinary therapy (surgery and chemotherapy) may prolong the survival of patients with G-CSF producing gallbladder carcinoma, especially those with recurrence. PMID:26945490

    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.

    Clear cell papillary renal cell carcinoma (CCPRCC) is a newly described variant of renal cell carcinoma (RCC) which is composed mainly of cells with clear cytoplasm arranged in cystic and papillary patterns. We report the clinicopathologic features, prognosis and differential diagnosis of 6 Clear Cell Papillary Renal Cell Carcinomas. The clinical information and follow-up data were analyzed. The patients were six males with median age of 52.5 years. Case 1 revealed dense calcification and ossification. Cases 2 and 3 contain a variably prominent smooth muscle stromal component. CA-IX, CK7, PAX-8 and VIM were positive in all cases. TFE3 and AMACR were not expressed in any tumor. CD10 was negative in 5 of 6 cases .The patients were followed for 13~55 months with no local tumor recurrences and tumor metastasis. The CCPRCC was associated with a more favorable outcome. These were low-grade and low-stage renal tumors. No lymph node or distant metastasis of the six tumors. PMID:26191150

    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.

    Spindle cell or sarcomatoid squamous cell carcinoma is an uncommon variant of squamous cell carcinoma of the vulva (SCCV) with only 12 well-documented cases reported to date. Morphologically tumors may be biphasic or monophasic, and uncommonly include heterologous elements. Only 1 reported vulval tumor has previously been investigated for human papillomavirus DNA content. We describe 4 women with spindle cell (sarcomatoid) SCCV, 3 of which occurred de novo and 1 followed radiotherapy for previous SCCV. The tumors in all 4 women arose in a background of lichen sclerosus, and 3 were associated with vulval intraepithelial neoplasia differentiated (simplex) type. All tumors were negative for human papillomavirus DNA on polymerase chain reaction analysis. One case is the second reported with malignant heterologous elements described in the vulva. These tumors seem to be more aggressive than conventional SCCV. PMID:24487477

    Primary neuroendocrine carcinoma (NEC) of the ureter is a rare entity, with few cases reported in the literature. These tumors are usually locally aggressive and are associated with a poor prognosis due to the thin walls of the ureter. This is the case report of a 69-year-old male patient who presented with left flank pain and gross hematuria. Following diagnosis of ureteral carcinoma, nephroureterectomy was performed. Postoperatively, the patient refused chemotherapy and radiotherapy, and succumbed to extensive metastases after 12 months of follow-up. The aim of the present study was to provide a literature review of NEC and its clinical and pathological characteristics, diagnostic methods and latest modifications in therapy. PMID:26870199

    Primary intraosseous squamous cell carcinoma (PIOSCC) derived from an odontogenic keratocyst (OKC) is a rare malignant neoplasm of the jaws, which is locally aggressive with quite poor prognosis. The incidence of carcinomas arising in odontogenic cysts was reported to be approximately 1–2/1000. The number of well-documented cases of PIOSCC ex OKC is extremely small; hence, no sufficient incidence data are available in the literature. Overall, the survival rate of an individual, which is a period of two years, is very poor, and this can be attributed to the delayed diagnosis. But knowledge of the histopathological and immunohistological features of PIOSCC allows accurate and early diagnosis of the lesion so that an early and appropriate treatment can be instituted for better prognosis. The following report describes an extremely rare case of PIOSCC of the mandible derived from an OKC in a 20-year-old female patient. PMID:23717337

    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

    Squamous cell carcinoma (SCC) is the second-most common malignant cutaneous cancer, with 60% occurring in the head and neck region. Metastases are uncommon and imply a more conservative prognosis. This report describes a case of parotid-invasive, facial squamous cell carcinoma, highlighting the importance of its prognostic and therapeutic management. The patient is an 81-year-old female, exhibiting extensive tumoral lesions in the pre-auricular region, affecting the parotid parenchyma and implying the metastatic involvement of the intra-parotid lymph node. Parotid involvement caused by SCC in specificity tumors is discussed herein. Parotid invasion is currently recognized as an isolated variable. It affects survival rates and determines certain changes in case management, such as the broadening of resection areas and adjuvant radiotherapy. PMID:27438204

    Renal cell carcinoma (RCC) may metastasize to mediastinal lymph nodes without any abdominal lymph node involvement. The present study describes an autopsy-proven case of RCC presenting with a large mediastinal mass; the case had been previously misdiagnosed as small cell lung carcinoma due to imaging analysis results, an elevated serum level of neuron-specific enolase and the presence of small atypical cells with a high nuclear/cytoplasmic ratio. Despite RCC occurrence being rare, it should be considered in the differential diagnosis, particularly when a mass located in the kidneys presents with metastases to the mediastinal lymph nodes, even if there is no involvement of the abdominal lymph nodes and the primary lesion is of a small size.

    Large cystic renal tumours can be confused with hepatic lesions even on crosssectional imaging. Careful clinical, sonographic and imaging analysis is needed for establishing correct diagnosis. We report a case of papillary cystic renal carcinoma in a 60 year old man, which was confused with amoebic liver abcess and was initially drained. Subsequent recurrence of symptoms prompted us to re-evaluate the case and repeat sonography confirmed the extrahepatic origin of mass based on simple observation that the liver and mass were moving separately on inspiration. Later guided aspiration from solid component of the mass confirmed the diagnosis as renal cell carcinoma. He was successfully treated with radical nephrectomy with uneventful post-operative recovery.

    Anaplastic lymphoma kinase (ALK) translocation renal cell carcinomas (RCCs) have been reported by several independent groups in recent times. The clinical behavior and histopathologic characteristics of these carcinomas are not fully understood because of the paucity of cases reported. Here, we describe 2 cases of RCC harboring a novel striatin (STRN)-ALK fusion. The first case was a 33-year-old woman with no sickle cell trait who underwent nephrectomy for right renal mass and had late recurrence in para-aortic lymph nodes twice 10 and 12 years after initial surgery. After the second recurrence, she was carefully observed without any treatment. Twenty-six years after the initial nephrectomy, the second para-aortic lymphadenectomy was performed, and gastrectomy was performed for newly developed primary gastric cancer. The resected para-aortic lymph nodes were largely replaced by metastatic carcinoma. The second case was a 38-year-old man with no sickle cell trait who underwent cytoreductive nephrectomy followed by sunitinib therapy for metastatic RCC. In both cases, the tumor showed solid, papillary, tubular, and mucinous cribriform structures. Psammoma bodies were occasionally seen in the stroma. Tumor cells had a large nucleus and prominent nucleoli with predominantly eosinophilic cytoplasm. Rhabdoid cells and signet-ring cells were also observed. Intracytoplasmic mucin deposition and background mucinous stroma were confirmed. In the second case, tumor necrosis was seen in some areas. Tumor cells exhibited diffuse positive staining for ALK in both cases. ALK translocation was confirmed by fluorescent in situ hybridization, and further gene analysis revealed a STRN-ALK fusion. These cases provide great insights into ALK translocation RCCs. PMID:26848800

    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. PMID:27075025

    Primary mucoepidermoid carcinoma (MEC) of the thyroid and columnar cell variant of papillary carcinoma of the thyroid (PCT) are uncommon neoplasms. We report the first case of composite MEC and columnar cell variant of PCT. An 86-year-old man consulted for a 47-mm thyroid nodule, cytologically compatible with PCT. Total thyroidectomy was performed. Histological diagnosis, with support of histochemistry and immunohistochemistry, was mixed primary carcinoma of the thyroid, associating an MEC component with predominantly columnar cell variant of PCT. Sixteen months after surgery and external beam radiation therapy, the patient was free of recurrence or distant metastasis. This case report offers an opportunity to highlight the potential pitfalls concerning the interpretation of mucin histochemistry in thyroid tumors. PMID:26755714

    Mixed adenoneuroendocrine carcinoma (MANEC) is a rare disease, which mostly occurs in the gastrointestinal tract and pancreas. Here we report a case of gastric MANEC with tri-lineage differentiation in which only the neuroendocrine component had metastasized to the liver. Liver and gastric masses were detected by abdominal computed tomography, and the preoperative relationship between liver and gastric masses was unknown. The histopathological analysis after operation confirmed the gastric mass to be MANEC, whereas the liver mass was actually the metastatic neuroendocrine component of the gastric MANEC. In the pathologic diagnosis, tri-lineage differentiation, including tubular adenocarcinoma, neuroendocrine carcinoma and squamous cell carcinoma was observed in the gastric MANEC tissues. The mitotic and Ki-67 labeling indexes of the resected tumor tissue were high, and thus, the tumor was classified as a grade G3 neuroendocrine carcinoma, which has a poor prognosis. Multiple low-density masses were found in the right lobe of the liver 2.5 months after operation. PMID:25337287

    Anal squamous cell carcinoma is more common in HIV-positive homosexual men than in the general population and prognosis worsens with increasing tumour size. To identify opportunities for earlier diagnosis, we aimed to determine size and visibility of anal squamous cell carcinoma at diagnosis. We conducted a retrospective review of medical records between 1992 and 2010 from one hospital radiotherapy centre, a major centre for HIV care, in Melbourne, Australia. Of 128 cases of anal squamous cell carcinoma, 24 (19%) were in HIV-positive men. At diagnosis, half (52%) of the tumours were externally visible and mean estimated tumour size was 36 mm (29 mm in HIV-positive and 38 mm in HIV-negative patients; p = 0.04) and 114/121 (94%) tumours were 1 cm or larger. The most frequent symptoms were bleeding (43%) and pain (36%) and mean duration of symptoms was 22 weeks. This suggests most anal squamous cell carcinoma were visible or palpable for some time before diagnosis, meaning that screening high-risk groups by anal inspection and palpation is plausible.

    In patients with organ transplantation as compared to the general population the risk of cancer is significantly increased. The most common changes are malignant tumors of the skin, constituting 30-65% of malignant tumors found in recipients. Potential risk factors for skin cancer after a transplant operation are: solar radiation, immunosuppressive therapy, genetic factors, infection with HPV and skin cancer transmission before transplantation. In contrast to the immunocompetent population, skin cancers in transplant recipients are dominated by squamous cell carcinoma, followed by basal cell carcinoma. Squamous cell carcinoma in patients after transplantation is characterized by a strong tendency to give local recurrences and distant metastases. Due to the high risk of developing skin cancer in transplant recipients, preventive oncology plays an important role in the long-term care of patients after transplantation. This includes: sun protection, education, and early treatment of patients with precancerous lesions. It is also stressed that systematic dermatologic studies need to be carried out in patients after transplantation surgery. The paper contains basic information about skin cancers in organ transplant recipients: epidemiology, potential risk factors, treatment and prognosis. The paper presents also a case of patient who developed squamous cell carcinoma of the skin 3 years after renal transplantation. PMID:24278050

    We present the case of a 73-year-old woman with pure squamous cell carcinoma in situ of the left breast. This non-invasive malignancy exhibited pure squamous type of architectural and cytologic features without any evidence of glandular differentiation either in the initial needle core biopsy or in the subsequently performed excisional biopsy and simple mastectomy. The tumor spanned 1.6 cm, involved numerous ducts and terminal ducts and extended into lobules, and was characterized by keratinizing squamous cells with intermediate-grade nuclei. Intercellular bridges extended between the malignant squamous cells. Keratinous debris with "pearl" formation was evident in most involved glands. No invasive carcinoma was identified. There was no evidence of metastatic disease in the ipsilateral sentinel lymph nodes. Thus far, only three cases of squamous cell carcinoma in situ of the breast have been reported in one series-none of which showed any evidence of recurrent or metastatic disease at last follow-up. In our case, treated exclusively by surgery, there was no evidence of disease 11 years after diagnosis. PMID:27279634

    Micropapillary carcinoma was originally reported to be an aggressive variant of breast carcinoma, and it is associated with frequent lymphovascular invasion and a dismal clinical outcome. It has subsequently been found in other organs; however, at present, only a limited number of cases of colorectal micropapillary carcinoma have been reported. We present a case of early colon cancer with extensive nodal metastases in a Japanese patient. An 82-year-old man was found by colonoscopy to have a 20-mm pedunculated polyp in his sigmoid colon. Endoscopic resection of the sigmoid colon tumor was performed, and pathological examination of the resected specimen revealed a poorly differentiated adenocarcinoma component and a micropapillary component. Despite the tumor being confined within the submucosa, massive lymphatic invasion was noted. Thereafter, the patient underwent laparoscopic sigmoidectomy with lymph node dissection, and multiple lymph node metastases were observed. Our case suggests that when a micropapillary component is identified in a pre-operative biopsy specimen, even for early colorectal cancer, surgical resection with adequate lymph node dissection would be required because of the high potential for nodal metastases.

We report a case of intraosseous mucoepidermoid carcinoma of the mandible in an 80-year old female patient developing from a previously diagnosed dentigerous cyst. An excisional biopsy was performed and the histopathological features confirmed low grade-cystic intraosseous mucoepidermoid carcinoma. The origin of central mucoepidermoid carcinoma could be suggested to be from the epithelial lining of previously diagnosed dentigerous cyst. Thus, emphasizing the need for careful examination of the entire excision specimen to rule out such neoplastic transformation of epithelial lining of odontogenic cyst and provide appropriate and effective treatment.

    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

    Regardless of the rare occurrence of metastatic lesions to the jaw, it should be taken into consideration in the individuals with a history of malignancy. Early detection requires accurate examination, and microscopic evaluation is essential. In this paper we report a case of breast carcinoma to the mandible as female breast cancer is the most frequent metastatic lesion to the mandible and its metastasis is well documented. The patient's medical history revealed that she had undergone mastectomy on the left breast three years ago. As this condition is infrequently described, documentation of new cases will augment the existing knowledge. PMID:26393225

    A comparative study has been realized to test the accuracy of ultrasonography and scintigraphy for detecting the presence of liver metastases in 305 patients with colorectal carcinomas. Presence or absence of hepatic metastases has been affirmed by laparotomy and biopsy. In the 47 cases with metastases, the sensitivity of ultrasonography was 93%, that of scintigraphy being 76%. In 258 cases without metastases the specificity of ultrasonography was 97%, that of scintigraphy being 92%. These results, confirmed by report in the published literature, show that ultrasonography should be the first examination for suspected hepatic metastases.

Histopathologically, the tumor was diagnosed as PIOSCC derived from an odontogenic cyst. Postoperatively, the patient has been followed up for 53 months, with no recurrence of the disease. We herein describe the clinical details, treatment results and histopathological characteristics of a rare case of PIOSCC derived from a maxillary odontogenic cyst with reference to the relevant literature.

    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

    Distant metastases are more common in follicular thyroid carcinoma (FC) than in papillary thyroid carcinoma. However, FC metastasis to the kidney with eggshell calcification, as observed in the present case, is rare. The current report presents a case of a 67-year-old woman exhibiting a solitary tumor in the mid pole of the left kidney. Radical nephrectomy was performed, as the tumor was diagnosed as a primary renal carcinoma using contrast-enhanced computed tomography. Once the tumor was confirmed to be FC, total thyroidectomy was performed. Following administration of an oral therapeutic dose of 100 mCi 131I, functional imaging demonstrated the presence of multifocal metastases in the chest and abdomen. Euthyrox® was prescribed orally to aid normal thyroid function. Follow-up 6 months later using radionuclide imaging demonstrated the disappearance of the multifocal metastases in the chest and abdomen. The distant metastasis of FC may represent the initial symptom of the primary lesion, which was neglected. Ultrasound is an effective method to examine nodules located on the thyroid. PMID:27123105

    The fibrolamellar variant of hepatocellular carcinoma (FL-HCC) is distinguished from other hepatocellular carcinoma's (HCC) by its unique clinical and pathological features. Cytological features of this tumor on fine needle aspiration have been described earlier. We report a rare case of a 17-year-old African American male with metastatic FL-HCC, diagnosed by body fluid cytology. The patient presented with ascites and computed tomography (CT) scan revealed multiple omental masses and liver lesions. The fluid sample was obtained along with the omental biopsy and was found positive for metastatic fibrolamellar hepatocellular carcinoma. The fluid cytology showed atypical polygonal cells with enlarged nuclei, prominent nucleoli, and abundant granular cytoplasm. Cytomorphologic features of FL-HCC presenting in body fluids have been rarely described before. This case enriches the cytopathology literature by providing awareness of this tumor presenting as metastasis in body fluids, especially in young individuals with liver lesions. Presence of a concurrent biopsy specimen provided cytohistological correlation, as it remains the gold standard for the accuracy and reliability of cytological diagnoses. Diagn.

    Miliary mottling on chest radiography is seen in miliary tuberculosis, certain fungal infections, sarcoidosis, coal miner's pneumoconiosis, silicosis, hemosiderosis, fibrosing alveolitis, acute extrinsic allergic alveolitis, pulmonary eosinophilic syndrome, pulmonary alveolar proteinosis, and rarely in hematogenous metastases from the primary cancers of the thyroid, kidney, trophoblasts, and some sarcomas. Although very infrequent, miliary mottling can be seen in primary lung cancers. Herein, we report the case of a 28-year-old female with chest X-ray showing miliary mottling. Thoracic computed tomography (CT) features were suggestive of tuberculoma with miliary tuberculosis. CT-guided fine needle aspiration cytology confirmed the diagnosis as lower-lobe, left lung non-small cell carcinoma (adenocarcinoma). It is rare for the non-small cell carcinoma of the lung to present as miliary mottling. The rarity of our case lies in the fact that a young, non-smoking female with miliary mottling was diagnosed with non-small cell carcinoma of the lung. PMID:23645961

    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. PMID:27602713

    Resection surgery for lung cancer is beset with specific or non-specific complications which often darken the prognosis for life. The specific complications, related to surgical dissections, are mainly per- and postoperative haemorrhages of various origins and, less frequently, disturbances in respiration, nerve wound or chylothorax. Soon after pneumonectomy a bronchial fistula encouraged by different factors may appear (3.3% of the cases) and empyema, usually caused by staphylococci, may develop (3%). Non-specific complications may disturb the post-resection period, involving the lungs (atelectasia, parenchymal infections, acute respiratory failure) or the cardiovascular system (pulmonary embolism, dysarrhythmia). The overall perioperative mortality rate has decreased with time owing to advances in anaesthesia and intensive care: in the hands of certain medico-surgical teams it does not exceed 3%. It is significantly lower in lobar (mean: 4.5%) than in pulmonary (mean: 8.4%) resections. Enlarged resections and lymph node dissections are aggravating factors. Patients aged 70 or more do not tolerate these operations so well: their mean overall mortality rate is twice that observed in younger patients (8% on average and up to 20%). Resection surgery for lung cancer remains a necessarily hazardous procedure but is the only treatment that can cure the patient. Its success is directly conditioned by a good preoperative risk evaluation. PMID:1303584

    Prostate cancer is one of the most common cancers among men worldwide and in the USA. Most prostate cancer progression either locally invades to seminal vesicles or metastasizes distally to bone. Skin is not a common site of metastasis for the majority of malignancies including prostate cancer. This paper reports two extremely rare cases of prostate carcinoma metastatic to the skin: a 74-year-old man previously treated with radiation for prostate cancer with cutaneous metastases to the shoulder and a 68-year-old man with prostate adenocarcinoma and cutaneous metastases to the groin. Both patients were diagnosed with skin punch biopsy and later confirmed with immunohistochemical staining for PSA and prostate specific acid phosphatase, specific for prostatic carcinoma. Although unusual, development of multiple skin lesions in patients with prostate adenocarcinoma should raise the flags of cutaneous metastases. PMID:27568675

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

    Giant basal cell carcinomas (GBCCs) are a strange and aggressive variety of basal cell carcinomas (BCCs); they are characterized by deep tissue invasion, rapid growth, high risk of metastasis, and a poor prognosis. GBCCs represent 0.4%-1% of all BCCs. The pathogenesis of GBCC is sometimes linked to a spontaneous mutation in the PTCH gene, mapped to the q22.33 locus of chromosome 9. The key factor in the development of GBCC, in at least 30% of the cases, is the delay in seeking medical attention (7.5 ± 3.1 years). This is associated to a poor socioeconomic level, deficient hygiene, mental illness, advanced age, and the fact that BCCs are painless lesions. The authors present a Mexican female with a 2-year ulcer diagnosed as a GBCC in the year 2000, its initial therapeutic approach, and her follow-up during the next 12 years. PMID:26332533

    We present the first reported case of clear cell carcinoma associated with a midurethral tape (MUT), the possible hypotheses and the management pitfalls we encountered. We report a 58-year-old woman who presented with symptoms of urinary tract infection and acute retention of urine associated with vaginal tape exposure 10 years after placement of an inside-out transobturator tape. She subsequently had a partial transobturator tape excision and a diagnostic cystoscopy, which revealed inflammatory changes within the urethra. Postoperatively, her symptoms persisted and the vaginal epithelium healed poorly. A biopsy of the friable tissue reported clear cell carcinoma. Imaging showed a locally invasive periurethral mass and bony and lymphatic metastases. This was treated with palliative radiation therapy. She was still receiving palliative care 5 months after the initial surgery. PMID:26590136

    Androgen excess is one of the most common and disturbing endocrine disorder of reproductive-aged women, affecting approximately 7% of this population Androgen excess results in the development of androgenic features in the women affected, with the development of hirsutism, androgenic alopecia, ovulatory dysfunction, and, if extreme, even virilization and masculinization. Adrenocortical carcinoma (ACC) is a rare malignancy accounting for 0.02% of all annual cancers reported. About 60% are functional tumors secreting hormones, with its consequent clinical manifestations, the Cushing's syndrome due to cortisone, virilization due to androgens, feminization due to estrogens, or hypertension due to aldosterone. Adrenal tumors that secrete androgens exclusively are extremely rare. Here, we present a rare case of androgen-secreting adrenocortical carcinoma with non-classical congenital adrenal hyperplasia.

    Coexistence of tuberculosis (TB) in the breast or axillary lymph nodes with breast carcinoma though rare is not unknown. A 55-year-old woman presented with right axillary and left supraclavicular lymphadenopathies with no detectable lesion in either breasts or left axilla. Right axillary lymph node excision biopsy revealed metastatic adenocarcinoma. Diagnostic workup showed intense fluorodeoxyglucose (FDG)-avid lymph nodes on the left side neck at level V, supraclavicular, axillary, subpectoral and para-aortic regions, and low FDG activity in the right breast. Core biopsy of right breast lesion was reported as invasive ductal carcinoma and cytology of multiple left axillary lymphadenopathies as reactive hyperplasia. Excision biopsy of the supraclavicular lymph nodes unveiled the diagnosis of TB. She underwent right-modified radical mastectomy followed by external beam radiotherapy, has completed antituberculous treatment and is on follow-up. Extrapulmonary TB though uncommon; may be found in certain cases. Clinicians must be aware of its existence. PMID:26881597

    Papillary renal cell carcinoma (PRCC) is a rare malignant tumor entity compared to common clear cell renal carcinoma. In the present study, we report a patient who was diagnosed with PRCC twice and successfully treated each time following renal transplantation. The first PRCC was located in the left native kidney two years following transplantation, and the second PRCC was diagnosed in the allograft 13 years following transplantation. The two tumors were completely removed by surgery in stage I of the disease with sufficient conservation of the allograft function. Notably, the tumors had a different origin as indicated by the microsatellite analysis, which reflects the exceptional course of the case. Risk factors for PRCC were identified in our patient. We concluded that high-risk candidates for malignancies in renal transplant recipients should receive shorter ultrasonic screening intervals, which may facilitate early tumor detection and improve outcome rates.

    Gastric cancer (GC) is the most prevalent malignancy in the world, especially in China. GC has been postulated to spread via several different routes, including through hematogenous channels, lymphatic vessels, the seeding of peritoneal surfaces, direct extension through the gastric wall, and retrograde extension through the vas deferens or lymphatics. Testicular metastasis is rare. We show here a 53-year-old patient with GC who underwent a radical total gastrectomy approximately 22 mo ago after he presented with a sensation of heaviness and swelling of the right hemiscrotum. The diagnosis of metastatic adenocarcinoma was made after a right-side orchiectomy. We report the first case of testicular metastasis from gastric adenocarcinoma in mainland China and summarize the clinicopathologic features of the disease based on previously published papers.

    Mucocele-like tumors (MLTs) of the breast are rare, with only 11 cases reported from Japan and 35 cases from other countries. MLTs of the breast were first described by Rosen in 1986. They are believed to be related to atypical ductal hyperplasia, ductal carcinoma, or mucinous carcinoma. It is difficult to diagnose this tumor preoperatively, and especially difficult to differentiate between benign and malignant forms. We report a case of MLT associated with ductal carcinoma in situ, which was initially diagnosed as fibroadenoma by mammography and ultrasonography, and as mucinous carcinoma by fine-needle aspiration cytology. We discuss the characteristic findings of imaging and the appropriate clinical treatment of this tumor. The characteristic image first signals the possibility of this tumor, following which the diagnosis can be confirmed by pathological examination of a fully excised tumor specimen. Breast-conserving surgery is recommended because of the low risk of high-grade malignancy, even when malignancy is confirmed, and lymph node dissection may be avoided. PMID:22237901

    Thyroid nodules are encountered in clinical practice during the diagnostic procedures or patients' follow-up due to other diseases quite far from the thyroid gland with prevalence 4-50% in general population, depending on age, diagnostic method and race. The prevalence of thyroid nodules increases with age and their clarification should be done for their adequate treatment. An 18F-FDG PET/CT was done with a PET/CT scanner (Philips Gemini TF), consisting of dedicated lutetium orthosilicate full ring PET scanner and 16 slice CT. The PET/CT scan of the whole-body revealed on the CT portion a hypodense nodular lesion in the left lobe of the thyroid gland with increased uptake of 18F-FDG on the PET with SUVmax 10.3 and demonstrated a complete response to the induction therapy of the main oncological disease of the patient--squamous cell carcinoma. This clinical case demonstrates that whole-body 18F-FDG-PET/CT has an increasingly important role in the early evaluation of thyroid cancer as a second independent malignant localization. Focal thyroid lesion with high risk of thyroid malignancy was incidentally found on 18F-FDG PET/CT. PMID:25088110

    Background: The human papilloma virus (HPV) is a carcinogen known for its strong association with cervical cancers and cervical lesions. It is also known to be associated with a variety of squamous cell carcinomas in other areas, such as the penis, vulva, anus and head and neck. However, the association with urothelial carcinoma remains controversial. Here, we report a case of urothelial carcinoma with squamous differentiation associated with HPV-6/HPV-11. Case presentation: This is a case of a 70 year old man who presented with nocturia and pressure during urination. During the TURP procedure for what was clinically thought to be benign prostate hyperplasia with pathologic diagnosis as prostate carcinoma, a 2 cm papillary mass was found in the distal penile urethra. The papillary mass was found to be a high grade urothelial carcinoma positive for GATA 3 expression, with focal areas of squamous differentiation. The areas with squamous differentiation demonstrated koilocytic differentiation, which were positive for strong p16 expression. The tumor was found to harbor low risk HPV 6/11 by in situ hybridization. Conclusions: This study case demonstrates HPV infection with a low risk subtype (HPV 6/11) associated with an urothelial carcinoma with squamous differentiation and condylomatous features.

    Collecting duct carcinoma (CDC), which is also known as Bellini duct carcinoma, accounts for less than 1% of all renal cell carcinoma, which has a poor prognosis. Predominantly, clinicians recognize this disease due to past experience and case reports, and a standard treatment is yet to be established. The present case report describes a 57-year-old male patient with CDC who was successfully treated with a left laparoscopic radical nephrectomy without any adjuvant therapy and compares the present patient's clinical presentation with previously reported cases. By analyzing the differences between these cases, the findings of the present case report and literature review suggested that surgery alone remains the only suitable choice for patients with advanced CDC.

    Paraneoplastic syndromes (PS) occur less commonly in association with otolaryngologic neoplasms than other carcinomas such as those of lung or breast. Piriform sinus carcinoma with PS is extremely rare. We here report a case of piriform sinus carcinoma accompanied by PS that was initially misdiagnosed as adult onset Still’s disease and describe our diagnosis and treatment. One lesson we have drawn from the experience of this misdiagnosis is that PS symptoms may manifest before the primary tumor is evident and complicate the diagnostic process. PMID:26770614

    Introduction The occurrence of two synchronous, primary cancers is rare. Thyroid carcinoma is incidentally found in the resection specimen after surgery for head and neck cancer in 0.3–1.9% of the patients. Presentation of case In this report, we describe the case of a 72-year-old patient in whom a primary (synchronous) papillary thyroid carcinoma was found coincidentally upon pathologic examination of lymph nodes recovered from the cervical neck lymph node dissection specimen after a ‘commando’ procedure for carcinoma of the oral cavity. Discussion and conclusion There is no gold standard concerning treatment of the incidentally discovered thyroid gland carcinoma. The decision to perform surgery depends on the life expectancy of the patient, whether the thyroid gland demonstrates clinical or radiologic lesions, the already completed treatment for the head and neck cancer and should always be adjusted to the specific patient.

    Metastatic pancreatic cancer is rare, accounting for approximately 2% of all pancreatic malignancies, and most cases arise from renal cell carcinoma. We report the case of a 63-year-old woman, who presented with a pancreatic tumor detected during her annual health examination. She had undergone left nephrectomy 13 years previously for renal cell carcinoma. Computed tomography (CT) revealed two tumors in the head and body of the pancreas, a hypervascular tumor and a hypovascular tumor with an enhanced rim, respectively. She underwent pylorus-preserving pancreaticoduodenectomy, and metastatic pancreatic tumors arising from the kidney with clustered clear cell carcinoma immunohistochemically positive for CD10 were diagnosed. This report presents the different enhancement features of different lesions on CT scans. Because the enhancement features of lesions have been reported to vary according to the size of the metastatic tumor, a knowledge of the history of renal cell carcinoma is crucial for diagnosis.

    Mammary analogue secretory carcinoma (MASC) is a recently described tumor sharing the histologic, immunohistochemical, and molecular profile of secretory carcinoma of breast. We aimed to evaluate the morphologic and histochemical features needed/required for the diagnosis of MASC without adjunct of molecular analysis. Six retrospective cases suspicious for MASC and 5 prospective cases reported as MASC were included in the study. Molecular analysis of ETV6 by fluorescence in situ hybridization was performed at the University of Pittsburg, USA. The ages of the patients ranged from 9 to 60 years (mean, 27.5 years). Histologically, all tumors showed mixed growth patterns including microcystic, macrocystic, papillary, tubular, and solid, papillary the being most common pattern. The tumor cells showed round to oval vesicular nuclei with small nucleoli, and eosinophilic to vacuolated cytoplasm. All cases demonstrated luminal and cytoplasmic mucin on periodic acid-Schiff with and without diastase digestion and alcian blue stain. ETV6 fusion gene rearrangement by fluorescence in situ hybridization was detected in 10 of 11 tumors. Recurrences occurred in 3 patients, and 1 patient died of disease 5 years after surgery. In conclusion, MASC is a relatively rare salivary gland malignancy exhibiting distinct histologic and histochemical features which can help to differentiate it from other mimics. Histologically, papillary-cystic and microcystic patterns are the main clues to diagnosis. The follicular pattern of acinic cell carcinoma might represent MASC, as 4 cases in our series had this pattern. Two patients in our series were 9 and 9½ years old respectively, which are the youngest ages ever recorded for MASC. PMID:27180060

    Squamous cell carcinoma of the middle ear (SCCME) accounts for 1.5% of malignant tumors in the ear. Because of the low incidence and infrequent reports of SCCME, the extent of concordance between CT and MRI results, surgical findings, and pathology reports are not well-characterized. In the present study, we reported CT and MRI images in three SCCME cases, and assessed the relationship between these results and those of surgery and the pathological report. Middle ear carcinoma is frequently misdiagnosed before surgery. In three cases of middle ear carcinoma, CT revealed the following: 1) soft tissue density lesions centered around the middle tympanum, exhibiting increased density, with external auditory canal involvement; 2) damage and absorption in the mastoid area, ossicles, and facial nerve canal, characterized by an irregular, worm-eaten appearance, without sclerotic margins; and 3) lesion infiltration of the surrounding bony substance of the middle ear, temporal squama, temporomandibular joint, anterior wall of the sigmoid sinus, and horizontal segment of the canalis caroticus (in one case lesion invasion into the intracranial cavity occurred through sigmoid sinus walls; no signs of intracranial invasion were seen in the other two cases). Enhanced lesion imaging revealed partial heterogeneous enhancement. In one patient MRI revealed a defined mass in the mastoid area of the middle ear. Signals in the lesion were partially heterogeneous and similar to brain tissue in T1- and T2-weighted images. The lesion was significantly enhanced following application of a contrast agent, while the adjacent meninges also exhibited linear enhancement. No abnormal signals were detected in the brain parenchyma. The destruction of adjacent bone plates was poorly defined. The CT and MRI results were consistent with the invasive features of middle ear cancer documented in the post-surgery pathology report. PMID:25932267

    A 61-year-old woman was referred to surgery for incidentally found colonic polyps during a health examination. Physical examination revealed widespread eczematous skin lesion without pruritus in the perianal and vulvar area. Abdominopelvic computed tomography showed an approximately 4-cm-sized, soft tissue lesion in the right perianal area. Inguinal lymph node dissection and Mils’ operation extended to perianal and perivulvar skin was performed. Histologically, the anal canal lesion was composed of mucin-containing signet ring cells, which were similar to those found in Pagetoid skin lesions. It was diagnosed as an anal canal signet ring cell carcinoma (SRCC) with perianal and vulvar Pagetoid spread and bilateral inguinal lymph node metastasis. Anal canal SRCC is rare, and the current case is the third reported case in the English literature. Seven additional cases were retrieved from the world literature. Here, we describe this rare case of anal canal SRCC with perianal Pagetoid spread and provide a literature review. PMID:26447133

    Bladder metastasis of renal cell carcinoma (RCC) is relatively rare, and only 43 cases have been reported in the Japanese literature. In most cases, the histology of the primary site was clear cell type. Here, we report a case of bladder metastasis of chromophobe RCC. A 74-year-old man presented with asymptomatic gross hematuria. He had a history of chromophobe RCC treated with radical nephrectomy 11 years previously. Since cystoscopy revealed a papillary pedunculated tumor, he underwent transurethral resection of the bladder tumor (TUR-Bt). The pathological diagnosis was chromophobe RCC because the histological findings were similar to those of nephrectomized specimens. Four years after TUR-Bt, the patient received bacillus Calmette-Guérin (BCG) therapy under the diagnosis of carcinoma in situ of urothelial cancer of the bladder but not chromophobe RCC. There was no recurrence of chromophobe RCC within 5 years follow-up after TUR-Bt. To the best of our knowledge, there has been only one other case report of bladder metastasis of chromophobe RCC in the Japanese literature. PMID:27018407

    Bellini's duct carcinoma (BDC) is a rare and aggressive variant of renal cell carcinoma that possesses an extremely poor prognosis. The greater the grade or stage of disease, the poorer the prognosis tends to be. This study presents two cases of BDC; one case of low grade BDC and one case of high grade BDC in a 47-year-old male and 74-year-old female, respectively. The 47-year-old male patient presented with painless gross hematuria, which had lasted for 3 weeks and subsequently underwent purely laparoscopic nephroureterectomy. After 4-years of follow-up, the patient remained disease-free. By contrast, a right renal tumor was identified in the 74-year-old female patient during a routine examination. Radical right nephrectomy and lymph node dissection were performed, however, 10 months after surgery the patient succumbed due to wide-spread metastasis. The two cases reported in the present study not only represent excellent examples of the disease spectrum, but also act as a reminder of the possibility of detecting BDC in an early stage of disease. Therefore, the epidemiology of BDC has been discussed, and the aggressive growth pattern of BDC has been presented in terms of signs, symptoms and imaging examinations, including ultrasonography, computed tomography (CT), angiography and single photon emission CT, in the early stage of disease.

    The rare reports of mucinous variant of follicular carcinoma of the thyroid gland have not provided enough evidence to support the recognition of these tumors as a distinct clinicopathologic entity or to understand their etiopathogenesis. We report the fourth case of mucinous variant of follicular carcinoma displaying a minimally invasive tumor with diffuse expression of thyroglobulin, TTF-1, CD56, PAX-8, cytokeratins 7 and 19, in the absence of monoclonal carcinoembryonic antigen (CEA), cytokeratin 20, chromogranin, HBME-1, P63 expression, and BRAF gene mutation, in a 51-year-old woman who is alive without signs of disease 13 months after total thyroidectomy, bilateral neck dissection, and radioactive iodine. Herein, fine-needle aspiration cytology disclosed "worrisome" cytologic features consisting of large epithelial cells arranged in clusters or singularly, with high nucleocytoplasmic ratio, nuclear grooves and evident nucleoli which were shared by those of mucin-producing papillary thyroid carcinoma. Therefore, knowledge of the cytological and histopathological spectrum of this lesion is important to avoid misdiagnosis. The morphologic clues leading to the correct diagnosis of mucinous variant of follicular neoplasm have been correlated with the data of the literature, and the differential diagnosis is briefly discussed.

    Ethylenediaminetetraacetic acid-dependent pseudothrombocytopenia (EDTA-PTCP) is an in vitro phenomenon of EDTA-induced platelet aggregation at room temperature. This phenomenon consists of platelet clumping due to anti-platelet antibodies in blood anticoagulated with EDTA. It has been reported in patients with various diseases, including sepsis, multiple myeloma, acute myocardial infarction and breast cancer. Since unrecognized EDTA-PTCP may lead to inappropriate treatment, it should always be considered as a possible cause in patients with low platelet counts. This study identified a case of transient EDTA-PTCP in a patient with neuroendocrine carcinoma of the stomach. In the present study, a 50-year-old male presented with epigastric pain and a weight loss of 15 kg. The patient presented with EDTA-PTCP and was diagnosed with neuroendocrine carcinoma of the stomach. Following systemic chemotherapy, the tumor showed a marked regression and the EDTA-PTCP disappeared. The mechanism by which this occurred is not clear but an association of EDTA-PTCP with neuroendocrine carcinoma is strongly suggested. PMID:22807967

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

    Mucinous tubular and spindle cell carcinoma (MTSCC) is a distinct entity in the World Health Organization classification of kidney tumors since 2004. Herein, we report a case of a patient with MTSCC of the kidney. A 48-year-man visited our hospital with a chief complaint of occult blood in his urine, confirmed by urine occult blood reaction. Computed tomography revealed a solid tumor in the right kidney. The tumor was 40×38 mm in length and was slightly enhanced (cT1aN0M0). Therefore, we performed radical nephrectomy. On analysis of the resected specimen, we found that the number of comparatively small malignant cells had increased markedly, forming branched tubular cuboidal cells. Further more, positive results were obtained on staining the stroma with both PAS and alcian blue stains characteristic of papillary renal cell carcinoma ; however, extracellular mucinous material was found to be depleted. Therefore, we needed to differentiate between papillary renal cell carcinoma and MTSCC. Finally, on the basis of the immunohistochemical staining results-vimentin (+), CK34βE12 (-), and CD10 (-)-MTSCC was confirmed. PMID:23552753

    Two cases (spouses) of carcinoma of the ureter possibly induced by long-term use of analgesic were presented. Case 1: A 66-year-old female with hematuria was diagnosed as a carcinoma of the ureter in January, 1985 and underwent resection of the left kidney and the ureter with partial resection of the urinary bladder. In December, 1988 she died due to recurrent cancer. Case 2: A 70-year-old male (a husband of case 1 patient) with hematuria was diagnosed as a carcinoma of the ureter in August, 1987 and underwent resection of the kidney and the ureter of the left side. In October, 1988 he died due to recurrent cancer. These two patients had used routinely phenacetin because of persistent headache for about 20 and 15 years, respectively and the presumed total dose was amounted to 4 and 2.5 kg, respectively.

    Ameloblastic carcinoma (AC) is a rare primary odontogenic tumor that has histological features of both ameloblastoma and carcinoma. A total number of 92 case reports speak about its rare incidence, affecting mostly the mandible as a locally destructive lesion. The maxilla is affected even more rarely as only 35 cases have been reported until 2012 in scientific literature. The clinical course of AC is generally aggressive, with extensive local bone destruction. The most common clinical features include swelling, pain, trismus, significant bone resorption with tooth mobility, dysphonia and intraoral fistula. We report two cases of AC with aggressive behavior. PMID:24987603

    Pulmonary tuberculosis is an opportunistic infection that can be reactivated in immunocompromised conditions, for example, in malignancy or after liver transplantation. Hepatocellular carcinoma (HCC) has a high mortality rate because it is frequently diagnosed at an advanced stage. Although surgical resection is the established curative measure for HCC, it is only feasible for early-stage HCC. Transcatheter arterial chemoembolization (TACE) is the most common treatment modality for patients with unresectable HCC. However, repeated TACE sessions and, occasionally, the tumor itself can further impair the reserve hepatic function and immunity. We report 3 recent cases of HCC with reactivation of pulmonary tuberculosis after TACE. PMID:22761986

    Papillary thyroid carcinoma (PTC) composed by predominant solid areas is diagnosed as a distinct variant on histological samples. Here we present a case of PTC recognized preoperatively by fine needle cytology as a solid variant. This diagnosis was made by combining cytology with the detection of the BRAFVK600-1E mutation, the molecular hallmark of the solid variant of PTC. Histological and molecular evaluation of the surgical specimen confirmed this pre-operative diagnosis. Thus combining cytology to BRAF molecular analysis is useful to refine the cytological diagnosis of this variant also on FNC specimens. PMID:18353179

Imaging studies showed a left peri-renal hematoma and a mass in the left kidney. Left nephrectomy and adrenalectomy were performed. Pathological examination showed a ruptured aneurysm in the left adrenal gland. The renal mass was composed of tubules and acini of epithelial cells and a prominent leiomyomatous stroma. The tumor cells were positive for carbonic anhydrase IX, cytokeratin 7, and negative for AMACR, consistent with clear cell (tubulo) papillary RCC. PMID:27516974

    von Hippel–Lindau (VHL) disease is an autosomal dominant inherited tumor syndrome associated with mutations of the VHL tumor suppressor gene located on chromosome 3p25. The loss of functional VHL protein contributes to tumorigenesis. This condition is characterized by development of benign and malignant tumors in the central nervous system (CNS) and the internal organs, including kidney, adrenal gland, and pancreas. We herein describe the case of a 74-year-old man carrying the VHL gene mutation who was affected by simultaneous colorectal adenocarcinoma, renal clear cell carcinoma, and hemangioblastomas of CNS.

    We report a case of hepatocellular carcinoma (HCC) with multiple lymph node (LN) metastases. A 68-year-old man underwent hepatectomy at our hospital. Intrahepatic recurrence and swelling of multiple LNs were detected by enhanced CT 21 months later. FDG-PET was positive for multiple swollen LNs, but all were negative for the intrahepatic recurrences. Biopsy of para-aortic LNs was revealed LN metastases from HCC. Immunohistochemically, the LN metastases were composed of poorly differentiated HCC. The sensitivity of FDG-PET in patients with HCC varies in relation to degree of differentiation and decreased FDG uptake must be noted. PMID:23132040

    A patient with pancreatic carcinoma diagnosed in 2005 suffered from chronic abdominal pain 6 years later that did not respond to conventional pain treatment according to guidelines. Furthermore, several complementary medical approaches remained ineffective. In the long run, only an Iberis amara drug combination relieved pain sufficiently. The drug is registered in Germany for the indications irritable bowel syndrome and dyspepsia. The multi-target approach of this combination drug may account for the effectiveness under these fundamentally different pathophysiological conditions. No serious undesired effects have been described in the use of this drug for other indications and none were observed in this case. PMID:23097614

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

    Lymphoepithelioma-like hepatocellular carcinoma (LEL-HCC) is a rare form of undifferentiated carcinoma of the liver characterized by the presence of an abundant lymphoid infiltrate. Here, a case of LEL-HCC is described. An 81-year-old woman with a chronic hepatitis C infection was referred to the general surgery department of our hospital in August 2013 with a diagnosis of HCC. A past ultrasound examination had revealed a 60 mm-diameter nodular lesion in the third segment of the liver. After a needle biopsy, the lesion was diagnosed as HCC. The patient underwent surgery with a liver segmentectomy. Two additional nodes on the gastric wall were detected during the surgical operation. The histology of the removed specimen showed a poorly differentiated HCC with significant lymphoid stroma. Immunohistochemical studies revealed that the epithelial component was reactive for CK CAM5.2, CK8, CK18, CEA (polyclonal) and was focally positive for hepar-1 and that the lymphoid infiltrate was positive for CD3, CD4 and CD8. The tumor cells were negative for Epstein-Barr virus. The gastric nodes were ultimately determined to be two small gastrointestinal stromal tumors (GISTs). The synchronous occurrence of HCC and GIST is another very uncommon finding rarely described in the literature. Here, we report the clinicopathological features of our case, along with a review of the few cases present in the literature. PMID:26420974

    Primary peritoneal serous carcinoma (PPSC) is an extremely rare malignancy that was first described in 1959. This type of cancer arises from the peritoneal epithelium and is similar to serous ovarian carcinoma. A diagnosis of PPSC is typically made based on the Gynecology Oncology Group criteria; however, a correct differential diagnosis of PPSC is difficult preoperatively. The current study describes the case of a 66 year-old female patient presenting with abdomen distension. A computed tomography (CT) scan revealed abundant ascites in the abdominal cavity and omental infiltration. The results of positron emission tomography/CT showed hot uptake in the greater omentum. Furthermore, preoperative serum cancer antigen-125 levels were 1,032 U/ml. Upon surgical exploration, a whitish mass and nodule were found in the greater omentum. Therefore, omentectomy was performed. Pathological examination of the resected specimen revealed a diagnosis of PPSC. PPSC is extremely rare with few cases cited in the current literature. The present study describes a rare case of PPSC with a review of the literature. PMID:27313741

    Three patients’ medical history, clinical manifestation, imaging characteristic, therapy and prognosis of calvaria metastasis from follicular thyroid carcinoma (FTC) in our hospital were retrospectively analyzed by reviewing medical literature. In case one, the tumor in frontal bone and fossa orbital was total resected, no further treatment was performed, the patient gave up on therapy and died of extensive metastasis at 22 months after the initial operation. In case two, the tumor in parietal and occipital bone was total resected, the subtotal resection of bilateral thyroid gland and isthmus was performed and combined with therapy of Levothyroxine and 131I radio-iodine therapy, no evidence of tumor recurrence at 30 months after the primary operation. In case three, the tumor in occipital bone was gross total resected, total resection of bilateral thyroid gland and clearance of lymph node was performed after two months, adjunctive therapy with Levothyroxine, 131I radio-iodine and skull radiotherapy, no evidence of tumor recurrence at 21 months after the primary operation. Correct diagnosis of calvaria metastasis from FTC preoperative is difficult because it’s rarity, patients can survive for years after synthetic therapy including total resection of metastatic tumor, radical operation of thyroid carcinoma, adjunctive therapy of Levothyroxine, 131I radio-iodine and skull radiotherapy.

    Merkel cell carcinoma (MCC) has been reported in association with other types of cutaneous neoplasms within the same lesion, including squamous cell carcinoma, Bowen's disease, actinic keratosis, follicular cysts, trichoblastoma and lentigo maligna, among others. However, the association of MCC and sweat gland tumors has never been described in the literature. We report two unique cases of MCC that developed within cutaneous poromas. A 56-year-old male (Patient 1) and an 81-year-old female (Patient 2) presented with nodules on the upper arm and lower back, respectively. Histopathologic study of both cases revealed a tumor in the dermis composed of poroid and cuticular cells intermingled with a proliferation of small round cells that showed characteristic histopathological and immunohistochemical features of MCC. In both cases, the two neoplasms were tightly admixed and distinct, suggesting that the MCC could have developed within a previously existing poroma. No morphological features of transition between the two tumors were seen. Neoplastic cells of MCC expressed immunoreactivity for chromogranin, synaptophysin, neuron-specific enolase, CAM 5.2 and cytokeratin 20, the last two markers showing the characteristic paranuclear dot-like pattern. In contrast, the poroma cells only expressed cytokeratin MNF116. Metastatic deposits were not identified in the regional lymph nodes or distantly. PMID:25732727

    Thymic carcinoma is an exceptionally rare tumor, which has a very poor prognosis, differing from thymoma. Although cytotoxic chemotherapy is commonly used to treat advanced thymic carcinoma, its effectiveness has not been found to be sufficient. There are several reports that thymic carcinoma also harbors an oncogenic driver mutation, similar to lung cancer. A patient with a c-kit mutation-positive thymic carcinoma received imatinib followed by sunitinib consecutively, which are both c-Kit inhibitors. Although the patient had achieved long-term disease control for 21 months, the primary lesion and pulmonary metastases had increased in size by November, 2014. Following failure of imatinib treatment, the patient received sunitinib, a multiple kinase inhibitor, initiated in December, 2014. Following administration of sunitinib, a computed tomography scan revealed a partial response and the disease was effectively controlled with continued sunitinib treatment for 6 months, up to June, 2015. The patient achieved long-term disease control (~27 months) with imatinib followed by sunitinib. The efficacy of consecutive molecular-targeted therapy for thymic carcinoma was demonstrated in this case. Therefore, thymic carcinoma with oncogenic driver mutations should be treated with molecular-targeted agents rather than with cytotoxic drugs, and it may be suitable to treat c-kit mutation-positive thymic carcinoma as a mediastinal gastrointestinal stromal tumor.

Coincidently, on histology the tumors in liver and kidney were consisted of clear cancer cells, which arranged in haphazardly intermixed pattern without capsules. Immunohistochemically, the clear neoplastic cells in the liver were positive for HepPar-1, GPC3, and negative for nephrogenic markers; however, renal clear neoplastic cells were positive for CD10, RCC and Pax-8, but negative to liver-derived markers. These findings led to the diagnosis of simultaneous double primary clear cell carcinomas of kidney and liver. Multiple primary carcinomas of kidney and liver, especially both are primary clear cell carcinomas, are extremely rare neoplasms, only 1 case has been reported previously until now. To our knowledge, this is a report of multiple primary carcinomas arising from the liver and kidney and reminders us of differentiation diagnosis with carcinoma metastasis. PMID:25755808

    Primary hepatoid carcinoma of the ovary (HCO) is a rare aggressive tumor that typically presents at an advanced stage in postmenopausal women with unilateral or bilateral ovarian masses and elevated AFP and CA125. We report a case of HCO in a 73 year-old woman who presented with abdominal distention, weight loss, and a large lower abdominal mass. Postoperative serum AFP was markedly elevated and trended down with initiation of chemotherapy. Review of the literature revealed thirty-two reported cases with no consensus on histogenesis or consistent immunohistochemical profile other than positive AFP staining in all but one case. Although the optimal treatment has not yet been determined, tumor debulking surgery followed by a platinum and taxane based chemotherapy regimen has shown promise. Both serum AFP and CA125 appear to have prognostic value and can be used to follow response to treatment and screen for recurrence. PMID:26425726

    Urothelial carcinoma (UC) originated from renal pelvis is the common tumor of the urinary system, however, neoplasia of the renal pelvis in duplex kidneys is extremely rare, especially in the complete renal and ureteral duplex cases. We present the first case of renal pelvis UC of the upper moiety in a complete right renal duplex. This male patient has bilateral complete renal and ureteral duplex. To the best of our knowledge, this is the first reported case of renal pelvis UC in a complete renal duplex system. After this experience we feel that the diagnosis of renal pelvis UC in duplex kidneys is not so easy, and once the diagnosis is determined, the whole renal duplex units and bladder cuff or ectopic orifice should be excised radically.

    Numerous studies have reported an association between end-stage renal disease (ESRD) and malignancy. The predominant malignant tumor that occurs in patients with ESRD in Asian countries is urothelial carcinoma (UC). According to recent research, cases of UC in dialysis-dependent patients are associated with higher recurrence rates and more aggressive biological behavior compared with patients without ESRD. The necessity of 1-step total urinary tract exenteration for dialysis-dependent patients with UC is advocated by certain studies. The current study reports a case of metachronous bladder cancer and bilateral upper urinary tract tumor in a dialysis-dependent patient. Three separate surgeries were performed to remove the bladder, and left and right urinary tract, respectively. The question of whether the stepwise strategy or the 1-step surgery should be selected for such special cases remains in debate. PMID:27313734

    We report a rare case involving a patient with C3 vertebral body metastasis secondary to adenoid cystic carcinoma of the tongue.Five years after local resection of the primary tumor, magnetic resonance imaging showed a metastasis located in the left posterior border of the C3 vertebral body. Additionally, multiple pulmonary metastases were identified by computed tomography. Based on these findings, the patient underwent C2-3, C3-4 discectomy; C3 corpectomy; and titanium mesh fusion with a Zephir plate. The diagnosis was confirmed by the pathology findings. During 6 months of follow-up, the patient showed improvement and return of function of the cervical vertebrae, with no serious complications.Because of the scarcity of cases of vertebral metastases from tumors of the tongue in the literature, we have reported this case to add to the available evidence regarding this rarely encountered condition.

    A 67-year-old man with a history of multiple myeloma (treated with chemotherapy) was referred with a left hyperaemic conjunctival lesion covering almost 360° of the limbus and extending onto the corneal surface. Conjunctival biopsy revealed conjunctival intraepithelial neoplasia. Initial treatment consisted of topical and intralesional injections of interferon α-2b. The patient subsequently developed limbal stem cell deficiency resulting in a persistent non-healing corneal epithelial defect. This was successfully managed with total excisional biopsy of the lesion, combined with limbal stem cell autograft (from the fellow eye) and amniotic membrane transplantation. Histopathology revealed a conjunctival squamous cell carcinoma. The corneal epithelium completely healed postoperatively and there is no evidence of tumour recurrence at 1 year follow-up. This case highlights a rare case of advanced ocular surface neoplasia causing secondary limbal stem cell deficiency. Medical and surgical management of ocular surface neoplasia with limbal stem cell transplantation is effective in treating such cases. PMID:22121391

    We report an extremely rare case of pulmonary lipiodol embolism with acute respiratory distress syndrome (ARDS) after transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC). A 77-year-old man who was diagnosed with a huge HCC was admitted for TACE. Immediately after the procedure, this patient experienced severe dyspnea. We suspected that his symptoms were associated with a pulmonary lipiodol embolism after TACE, and we began intensive treatment. However, his condition did not improve, and he died on the following day. A subsequent autopsy revealed that the cause of death was ARDS due to pulmonary lipiodol embolism. No cases have been previously reported for which an autopsy was performed to explain the most probable mechanism of pulmonary lipiodol embolism; thus, ours is the first report for such a rare case.

    2014-01-01

    Introduction Basaloid squamous cell carcinoma is a rare and aggressive variant of squamous cell carcinoma. Basaloid squamous cell carcinoma is mostly seen in the upper aerodigestive tract and has a propensity for lymph node spread and systemic metastases. Various treatment modalities have been reported, including surgical excision supplemented with radiotherapy/adjuvant chemotherapy. To the best of our knowledge, treatment of nasal basaloid squamous cell carcinoma with proton beam therapy and cisplatin has not been described in the literature. Case presentation We report the case of a 56-year-old Japanese man with locally invasive basaloid squamous cell carcinoma in his right nasal cavity with invasion of the orbit, paranasal sinus, and buccal subcutaneous tissue. He underwent proton beam therapy concurrent with cisplatin. Acute and late side effects did not exceed grade 3. At 24-month follow up, he remains in complete remission. Conclusion Proton beam therapy concurrent with cisplatin may be one choice for locally invasive basaloid squamous cell carcinoma. PMID:24716457

    The breast is an unusual site for metastasis from a gastric carcinoma. The present study reports two cases of metastatic gastric carcinoma to the breast. The first patient, a 37-year-old woman, initially presented with gastric adenocarcinoma, prior to developing metastatic cancer to the breast 4 years later. The second female patient presented with a breast mass, and a modified radical mastectomy was performed; however, the subsequent pathological examination revealed the mass to be a metastatic signet ring cell carcinoma. An abdominal computed tomography scan revealed a diffuse gastric wall thickening that was consistent with gastric cancer. The findings suggest that immunohistochemistry is a useful tool to differentiate between primary breast tumors and gastrointestinal carcinomas that have metastasized to the breast. Additional studies are required in order to define the optimal treatment. PMID:27123067

    Background Mammary analog secretory carcinoma (MASC) was first described in 2010 by Skálová et al. This entity shares morphologic and immunohistochemical features with the secretory carcinoma (SC) of the breast. MASC usually presents as an asymptomatic mass in the parotid gland and predominantly affects men. This tumor is considered a low-grade carcinoma but has the potential for high-grade transformation. We report one MASC case and a review of world literature. Case report A 66-year-old male patient presented because he noticed a mass of approximately 3 × 3 cm on the right pre-auricular region. Physical examination demonstrated a 3 × 3.5 cm, firm, fixed, non-tender mass in the right pre-auricular region. An MRI of the head and neck showed an ovoid heterogeneous lesion, dependent of the right parotid gland of 27 × 28 mm. We performed a superficial parotidectomy with identification and preservation of the facial nerve. The immunophenotype was positive for epithelial membrane antigen (EMA), CK8/18, vimentin, S-100 protein, and mammoglobin. No further surgical interventions or adjuvant therapies were needed. The patient will have a close follow up. Conclusion The presence of t(12;15) (p13;q25) translocation which results in the ETV6-NTRK3 gene fusion or positive immunochemical studies for STAT5, mammoglobin and S100 protein, are necessary to confirm the diagnosis of MASC. MASC treatment should mimic the management of other low-grade malignant salivary gland neoplasms. The inhibition of ETV6-NTRK3 gene fusion could be used as treatment in the future. PMID:26496413

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

    Thirteen cases of primary endocrine carcinoma of the skin (Merkel cell carcinoma) were reviewed with the aim of defining the morphological, immunohistochemical and ultrastructural criteria for diagnosis. The tumour cells were characterized by their scanty cytoplasm, generally small uniform nuclei with finely dispersed chromatin and multiple small nucleoli. Nuclear shapes varied from round to spindle, with larger and pleomorphic forms predominating in 2 tumours. A striking feature seen in 12 tumours was the occurrence of a "ball-in-mitt" pattern represented by 1 or 2 crescentic tumour cells closely wrapped around an oval cell. Staining for neuron-specific enolase was the most consistent marker of the tumour and the characteristic juxtanuclear globular staining for keratin and cytokeratin and the occasional coexpression of neurofilament set this tumour apart from other cutaneous neoplasms, in particular, metastatic carcinoid tumours and oat cell carcinoma from the lung. The fine structural features of note were striking paranuclear or juxtanuclear whorls of intermediate filaments, seen in 7 cases, the presence of variable numbers of membrane-bound dense core granules of 80-150 nm diameter in all cases and cytoplasmic spinous or microvillous projections containing microfilaments in 4 cases. Less consistent characteristics of primary endocrine carcinomas of the skin included cell moulding, argyrophilia and immunohistochemical staining for ACTH, VIP and calcitonin. The high frequency of vessel invasion in this series is in keeping with the high rate of local recurrence, lymph node metastases and visceral dissemination reported. The distinction from other similar appearing tumours in the skin is discussed. PMID:2434904

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

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

    Renal carcinomas associated with Xp11.2 translocations/transcription factor 3 (TFE3) gene fusion (Xp11 translocation RCC) are a rare subtype of renal cell carcinoma. A middle-aged Japanese man, who had a medical history of dialysis for more than 12 years, had bilateral renal cancers with a background of acquired cystic disease of the kidney and remarkable deposition of calcium oxalate in the tumorous area. The right renal tumor showed papillary architecture of clear cells with diffuse and strong immunoreactivity for TFE3 and focal and weak positivity for cathepsin K, suggesting a possibility of Xp11 translocation RCC. However, RT-PCR failed to detect any type of the reported fusion genes involving TFE3. Thus, the sample was sent for a TFE3 break-apart FISH assay in a renal tumor consultation service, which reported no evidence of TFE3 gene rearrangement. The right renal tumor was finally diagnosed as papillary renal cell carcinoma with cystic change. We report here a case of bilateral renal cell carcinoma in a patient undergoing long-term dialysis, which showed false-positive immunoreactivity for TFE3 immunostaining. Titration of TFE3 immunohistochemical staining (IHC) should be performed and cross-referenced with the FISH or RT-PCR results to avoid the misinterpretation of TFE3 IHC results. PMID:24228124

    Background Oligometastasis, a recently proposed concept, is defined as an intermediate state of cancer, between localized and systemic disease, that may be well controlled by local ablative treatment. Thymic carcinoma is a rare cancer with a poor prognosis. A definitive management approach has yet to be confirmed by a high level of evidence. Case presentation We present the case of a 41-year-old female who underwent curative-intent surgery for a stage III squamous cell carcinoma of the thymus. Bone metastases were detected 1 year later by magnetic resonance imaging. These were treated with palliative-intent radiotherapy. Disease progression has not been observed in more than 15 years since the achievement of complete radiological remission. Conclusion The treatment outcomes in this and other reported cases suggest that some patients with oligometastatic thymic carcinoma may achieve prolonged survival or even cure with low-dose radiotherapy delivered to the metastases.

    The characteristic morphologic spectrum of tubulocystic renal cell carcinoma (TC-RCC) may include areas resembling papillary RCC (PRCC). Our study includes 15 RCCs with tubulocystic pattern: 6 TC-RCCs, 1 RCC-high grade with tubulocystic architecture, 5 TC-RCCs with foci of PRCC, 2 with high-grade RCC (HGRCC) not otherwise specified, and 1 with a clear cell papillary RCC/renal angiomyoadenomatous tumor-like component. We analyzed aberrations of chromosomes 7, 17, and Y; mutations of VHL and FH genes; and loss of heterozygosity at chromosome 3p. Genetic analysis was performed separately in areas of classic TC-RCC and in those with other histologic patterns. The TC-RCC component demonstrated disomy of chromosome 7 in 9/15 cases, polysomy of chromosome 17 in 7/15 cases, and loss of Y in 1 case. In the PRCC component, 2/3 analyzable cases showed disomy of chromosome 7 and polysomy of chromosome 17 with normal Y. One case with focal HGRCC exhibited only disomy 7, whereas the case with clear cell papillary RCC/renal angiomyoadenomatous tumor-like pattern showed polysomies of 7 and 17, mutation of VHL, and loss of heterozygosity 3p. FH gene mutation was identified in a single case with an aggressive clinical course and predominant TC-RCC pattern. The following conclusions were drawn: (1) TC-RCC demonstrates variable status of chromosomes 7, 17, and Y even in cases with typical/uniform morphology. (2) The biological nature of PRCC/HGRCC-like areas within TC-RCC remains unclear. Our data suggest that heterogenous TC-RCCs may be associated with an adverse clinical outcome. (3) Hereditary leiomyomatosis-associated RCC can be morphologically indistinguishable from "high-grade" TC-RCC; therefore, in TC-RCC with high-grade features FH gene status should be tested.

    Inverted Schneiderian papilloma is an uncommon benign tumor that presents tendency to recur and propensity to be associated with malignancy in approximately 10% of the cases. Some of these lesions are isolated in the maxillary sinus, and predominantly affect white males with mean age of 50 years. We report a case of squamous cell carcinoma arising from inverted Schneiderian papilloma in the maxillary sinus extending to the mouth. The patient was submitted to extraction of a maxillary molar tooth four months before the exacerbation of the symptoms of nasal airway obstruction and facial enlargement. Computed tomography scan revealed a sinonasal mass causing opacification of the right maxillary sinus with destruction of the lateral nasal wall and maxillary sinus floor. The patient was referred to an oncology center for treatment and died from tumor progression one year after the cancer was diagnosed. The intention of this report is to alert dentists to include the inverted Schneiderian papilloma, either associated with squamous cell carcinoma, or not, in the differential diagnosis of maxillary sinus tumors with aggressive behavior, which may extend to the oral cavity or involve roots of teeth.

    We report a case of a 44-year-old woman with bilateral ovarian carcinoma that had metastasized from the colon and mimicked primary mucinous cystadenocarcinoma. Macroscopically, both ovarian tumors were large, multiloculated cystic masses with abundant mucinous content. Histologically, they were lined with mucinous epithelium with mild to moderate nuclear atypia and showed stromal invasion and surface involvement. At first, the tumors were diagnosed as bilateral primary ovarian mucinous cystadenocarcinomas. However, three months after surgery, a large villous tumor was discovered in the ascending colon by colonoscopic examination and was surgically resected. Histologically, the colonic tumor was a villous adenomatous tumor with invasive components of mucinous adenocarcinoma composed of well-differentiated adenocarcinoma and exhibited abundant extracellular mucin production. As a villous adenomatous component was present in the mucosal area, the colonic tumor was considered a primary tumor. Therefore, the original diagnosis of bilateral ovarian tumors was revised for consistent with metastasis from the colon carcinoma, in line with the findings of immunohistochemistry and loss of heterozygosity analysis. This case highlights the importance of considering the possibility of metastatic tumors from the gastrointestinal tract in the diagnosis of mucinous ovarian tumors. PMID:24427362

    Ameloblastic carcinoma is a malignant form of ameloblastoma defined by histological evidence of malignancy in primary, recurrent, or metastatic tumor. Such a tumor is rare, and the maxilla is an unusual site. Due to its rarity, the characteristics of this tumor in the maxilla have not been well described. Case 1: A 55-year-old, ill-appearing Nigerian male presented to our center with left maxillary swelling of seven-year duration. The swelling had been slow-growing and painless until one year prior, when the growth became rapid and was coupled with severe pain. The swelling affected both oral function and facial esthetics, and the patient reported difficulty breathing. There was a maxillary, ulcerated swelling extending from teeth 12 to 18 and blocking the left nostril. The involved teeth were moderately mobile. Case 2: A 32-year-old male farmer presented with recurrent right maxillary swelling of six-year duration. Prior to this episode, he had undergone surgery for ameloblastoma (follicular type). The present swelling was fungating through the skin and protruding into the right nostril. Ameloblastic carcinoma is an aggressive odontogenic tumor that requires aggressive surgical treatment.

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

    Basal cell Carcinoma (BCC) is the most common type of skin cancer, 85% of BCC are located in the head and neck area, of which 30% on the nose. The author present a retrospective study, own experience in surgical treatment in 31 cases with basal cell carcinoma of the nose operated in the period 2005-2011. The age of patients was between 50 to 90 years old. The anatomical site of the nose the most frecvently involved was ala 58%, and followed of the nasal tip 18%, lateral nose wall 12%, dorsum 9% and 3% basalioma terebrans. In all of the cases in this study it was performed the repair of the skin tumour defects of the nose, using varied local skin flaps, septal graft and auricle cartilage free grafts a ndcomposite (skin + cartilage) of conchal and helical rim. Treatment methods were depend on the tumor localization and extension. The best treatment option in BCC of the nose was radical surgical excision whith safety margin of the tumour, followed of reconstructive rhinoplasty. PMID:22844837

    Colloid carcinoma (CC) of the pancreas, also known as mucinous non-cystic carcinoma, is a rare histological variant of pancreatic cancer. The present study reports the case of a 65-year-old male with a pancreatic head tumor 4.6×3.1 cm in size. The tumor had not invaded the superior mesenteric or celiac arteries. Laboratory data showed elevated alkaline phosphatase, γ-gluytamyl transpeptidase and cancer antigen 19-9 (CA19-9) levels. The patient underwent a pancreaticoduodenectomy (PD), and the pathology revealed CC extending to the submucosa of the duodenum, with mild atypical hyperplasia of the pancreatic duct. The patient was negative for circulating tumor cells, indicating a good prognosis. The CA19-9 concentration decreased to within the normal range following surgery. The present study reports a rare case of CC of the pancreas presenting with obstructive jaundice, in which a PD procedure was performed. Primary surgical treatment with curative intent is the optimal management and this subtype of pancreatic cancer is associated with a better prognosis compared with pancreatic ductal adenocarcinoma.

    Among primary thyroid neoplasms, papillary thyroid carcinoma (PTC) and primary thyroid lymphoma (PTL) are known to coexist and are pathogenetically linked with Hashimoto's thyroiditis (HT). However, HT occurring in association with medullary thyroid carcinoma (MTC) is rarely documented. We report here an interesting case. A 34-year-old female with a solitary thyroid nodule underwent fine needle aspiration cytology (FNAC) that was interpreted as “MTC with admixed reactive lymphoid cells, derived possibly from a pretracheal lymph node.” Total thyroidectomy specimen showed “MTC with coexisting HT.” At a later stage, a follow-up FNAC from the recurrent thyroid swelling showed features consistent with HT. As an academic exercise, the initial smears on which a diagnosis of MTC was offered were reviewed to look for evidence of coexisting HT that showed scanty and patchy aggregates of reactive lymphoid cells without Hürthle cells. Our case highlights an unusual instance of MTC in concurrence with HT that can create a tricky situation for cytopathologists. PMID:27279687

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

    Ovaries are a favored site for metastatic tumors arising in the female genital tract. Other organs of the mullerian system, that is, the uterine corpus as well as the fallopian tubes, cervix, and the vagina are less commonly involved by metastases. If there is no clinical history of a known extramullerian primary tumor, suspicion that a uterine mass represents metastatic disease is low. We report the case of a renal clear cell carcinoma presenting as an isolated uterine mass and morphologically mimicking a primary endometrial clear cell adenocarcinoma. A review of the English literature yielded only a recent abstract describing 3 cases of renal clear cell carcinoma metastasizing to the endometrium. PMID:26630224

    Carcinoma showing thymic-like elements (CASTLE) is a rare tumor affecting thyroid and neck soft tissues, which has to be distinguished from squamous cell and anaplastic thyroid carcinoma, because it has a better prognosis. We report a new case of CASTLE which occurred in a patient submitted to total thyroidectomy with central neck dissection. The tumor stained positively for CD5, which seems to be the most useful marker in the differential diagnosis. By the analysis of the 18 cases reported in literature, total thyroidectomy with selective modified neck dissection should be the treatment of choice and radiotherapy should be considered for patients with positive nodal status.

    Gastric adenosquamous carcinoma (ASC) is a rare type of gastric cancer. It is a mixed neoplasm, consisting of glandular cells and squamous cells. It is often diagnosed at an advanced stage, thus carrying a poor prognosis. We describe a case of a 73-year-old male, who presented with refractory fever and an intra-abdominal mass on imaging. He underwent a laparoscopic exploration followed by a successful totally laparoscopic total gastrectomy with D2 lymphadenectomy for gastric cancer. Postoperative pathology revealed primary gastric ASC (T4aN0M0). The patient received adjuvant radiotherapy and chemotherapy with S1 and is alive 20 mo after surgery without recurrence. This is the first case of advanced gastric ASC with fever as the initial presentation treated with totally laparoscopic total gastrectomy reported in the English literature. PMID:25110448

    Myiasis is the condition of infestation of the body by fly larvae (maggots). The deposited eggs develop into larvae, which penetrate deep structures causing adjacent tissue destruction. It is an uncommon clinical condition, being more frequent in tropical countries and hot climate regions, and associated with poor hygiene, suppurative oral lesions, alcoholism and senility. The diagnosis of Myiasis is basically made by the presence of larvae. The reported cases of oral Myiasis associated with oral cancer in the literature are few. This paper reports two cases of oral and maxillofacial Myiasis involving larvae in patients with squamous cell carcinoma in adult males. The condition was managed by manual removal of the larvae, one by one, with the help of forceps and subsequent management through proper health care. PMID:25709682

    Among neuroendocrine neoplasms, mixed exocrine and endocrine characteristics with at least 30% of each component are classified into mixed adenoneuroendocrine carcinoma (MANEC), according to the 2010 World Health Organization classification. We experienced a rare case of MANEC of the stomach with focal intestinal metaplasia and hypergastrinemia. A 76-year-old Japanese male was diagnosed as having gastric adenocarcinoma and underwent total gastrectomy. The pathologic diagnosis was MANEC of the stomach accompanied by unusual mucosal atrophy without Helicobacter pylori infection, the characteristics of which were different from both type A and type B atrophic gastritis. The patient has a history of long-term use of a proton pump inhibitor. Additional serum chemistry examination using preoperatively obtained plasma from the patient revealed hypergastrinemia. The mechanism of gastric MANEC carcinogenesis is still unclear, but that might be correlated with unusual intestinal metaplasia and hypergastrinemia in this case. PMID:25785345

    Basal cell carcinomas (BCCs) are one of the most frequent cutaneous malignancies. The majority of BCCs are reported to occur on the auricular helix and periauricular region due to ultraviolet light exposure. Despite the frequency of BCCs, those that develop within scar tissue are rare, and the phenomenon of keloid BCCs has rarely been reported in the literature. Keloid collagen within BCCs is associated with morphoeiform characteristics, ulceration, or necrosis. Extensive keloid collagen is often seen in BCCs of the ear region, a site prone to keloid scarring. This article presents a rare case of a secondary tumor (BCC) which arose on top of a primary tumor (keloid scar) on the right auricle region in a healthy 23-year-old female after an ear piercing 2 years prior. To our knowledge, the tumor described in this case, in contrast to keloidal BCCs, has never been reported in the literature. PMID:27536142

    Small cell carcinoma of the urinary bladder (SCCB) is a rare and aggressive form of bladder cancer with poor prognosis. Hematuria is the main symptom of this malignancy, and most patients have a history of smoking. The disease incidence of malignant bladder tumors in China is approximately 0.74%. Early and accurate diagnosis of SCCB can ensure timely and appropriate treatment of this malignant disease. Oncologic surgery is the standard treatment; however, it may not be a curative approach. Chemotherapy and/or radiotherapy should be performed following surgical removal. This case report describes a patient with a single neoplasm diagnosed as SCCB that arose because of recurrence of bladder cancer after bladder tumor resection. In contrast to previously reported cases, this patient had no gross hematuria and no history of smoking. PMID:26271292

    Cases of squamous cell carcinoma of the penis treated by surgery and radiation therapy at Moffitt Hospital, University of California, and Mount Zion Hospital and Medical Center are reviewed. Only cases followed for more than three years or with autopsy findings are presented. For the primary lesion, over-all surgical control rate locally was 15/17 or 88 per cent. Over-all control rate with radiation therapy alone was 9/12 (75 per cent), and with surgical salvage 11/12 (92 per cent). Radiation therapy appears to be the treatment of choice for early stage lesions, reserving surgery for salvage. Prophylactic ilioinguinal lymph node dissection for N0 lesions is not warranted. The role of chemotherapy needs further investigation.

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

    Sarcomatous carcinomas (SCs) are rare tumours that contain malignant cells with epithelial and mesenchymal characteristics. SC rarely presents in the head and neck, and occurs even less often in the orbit. Only 8 cases of SCs located in the orbit or affecting the globe function have been described in the English literature. Here, we report a case of SC affecting the right orbit. SC is associated with a poor prognosis and advanced disease at presentation. Diagnosis is difficult, as histology often fails to definitively identify SC, necessitating a wide panel of molecular/immunological markers. Treatment options are generally aggressive but risky, and frequently yield poor results. Due to the rarity of SC, there has been little focus on the development of improved treatment options.

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

We report a case of septicemia in a 76-year-old male patient with underlying hepatocellular carcinoma due to A. xylosoxidans, which showed a different antimicrobial susceptibility pattern from what is usually reported. From aerobic blood culture of the patient, A. xylosoxidans was isolated which was found to be sensitive to amoxicillin-clavulanic acid, piperacillin-tazobactam, ceftazidime, cefoperazone-sulbactam, meropenem, minocycline, tigecycline, and trimethoprim/sulfamethoxazole. The patient recovered with amoxicillin-clavulanic acid treatment, which was given empirically to the patient. The present case highlights the possible role of amoxicillin-clavulanic acid for treatment of bloodstream infection with A. xylosoxidans. PMID:26417165

    Oral melanotic lesions, including melanin pigmentation, melanocytic nevus, and malignant melanoma, are well-recognized pathologic entities. However, melanocytic proliferation within malignant oral mucosal lesions is not well documented. We report the unusual case of a 53-year-old Japanese man who developed oral carcinoma in situ (CIS) with melanocytic proliferation and melanin pigmentation in the epithelial layer. The patient, a nonsmoker and an opportunistic drinker, presented with a brown tongue lesion. Initial examination found a large brown pigmented area and multiple small white patchy areas on the right tongue border. The pigmentation had an ill-defined border with uneven color distribution. Physical examination found no abnormalities. Ultrasonography did not find a deeply infiltrating lesion. Oral mucosal malignant melanoma in situ was diagnosed, and partial tongue resection was performed. Histopathologic examination found oral pigmented CIS. To the best of our knowledge, this is only the third reported case of oral pigmented CIS. PMID:24746807

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

    From a clinical point of view, the most common presentations of cutaneous metastatic disease are papules and nodules. However, a wide morphological spectrum of lesions has been described, including erythematous patches or plaques, inflammatory erysipelas-like lesions, diffuse sclerodermiform lesions with induration of the skin, telangiectatic papulovesicles, purpuric plaques mimicking vasculitis, and alopecia areata like scalp lesions. The so-called zosteriform pattern has been described to be in few cases and to the best of our knowledge has never been described associated with a metastasis of a nasopharyngeal carcinoma. This case highlights the relevance of including cutaneous metastases in the differential diagnosis of patients with nonhealing herpes zoster-like lesions, especially in those with underlying neoplasm recently diagnosed.

    Extramedullary hematopoiesis (EMH) is a phenomenon in which hematopoietic cells are found in sites other than the bone marrow. It is usually observed in the liver and spleen but may occasionally be found within solid tumors. The current case report presents a 69-year-old female patient who presented with a renal cyst. Histopathological examination following surgical removal of the cyst revealed a lining of oncocytic- and chromophobe-type cells with capsular invasion and a mass forming EMH with evident bone trabeculae within the cyst wall. Circulating hematopoietic stem cells in the blood and their colonization within tissues is discussed in the present case report, emphasizing certain types of renal cell carcinoma. PMID:24520308

    An unusual case of metastatic bronchioloalveolar carcinoma of the lung presented as a pituitary tumour in a young adult Chinese female, who subsequently died after having undergone trans-sphenoidal resection. Metastatic cancers of the pituitary are uncommon even in necropsy series and rarely give rise to clinical symptoms. This case draws attention to the fact that, although uncommon, pituitary metastases have been noted with increasing frequency and their distinction from primary pituitary tumours is often difficult. A metastatic pituitary tumour may be the initial presentation of an unknown primary malignancy, wherein the metastatic deposits may also be limited to the pituitary gland. Clinicians and pathologists alike should consider a metastatic lesion in the differential diagnosis of a non-functioning pituitary tumour. Images PMID:10070337

    Hepatocellular carcinoma was diagnosed in five slender tailed meerkats (Suricata suricatta) housed at the Smithsonian Institution's National Zoological Park between 1980 and 2013. Animals included four females and one male, ranging from 7 to 15 yr of age. Common clinical signs included weight loss and lethargy. Three of the neoplasms originated from the right medial liver lobe and were located adjacent to or partially incorporated in the gall bladder. Three animals had solitary masses, and two animals had multiple hepatic masses; all were characterized by polygonal to round neoplastic hepatocytes arranged in a trabecular pattern with smaller regions of varied solid, adenoid, and rarely peliod cell patterns. Hemorrhage and necrosis often with cystic degeneration was noted in all five cases. There was no evidence of metastatic disease in any of the cases examined. PMID:24712172

    Myoepithelial carcinoma (MECA) is one of the rarest salivary gland neoplasms, which may either arise de novo or develop within a preexisting pleomorphic adenoma or benign myoepithelioma. The tumor occurs mainly in the parotid gland followed by minor salivary glands and other body sites. As a result of their morphologic heterogeneity, they can be confused easily with many tumors. Awareness of their unique cytoarchitectural patterns and immunohistochemical profile is crucial for accurate identification. Herein, we report a rare case of a 51-year-old female patient with MECA of the maxillary sinus that metastasized to the pleural fluid. To the best of our knowledge, this is the first case of pleural fluid involvement by MECA reported in the literature. PMID:27382407

    There is a low incidence of multiple primary cancer, particularly when the cancer is synchronous. The present report presents a case of synchronous double primary malignancies. A 58-year-old woman was admitted to Ling Nan Hospital (Guangzhou, China) complaining of pain in the left hip. X-ray revealed an osteolytic lesion and further examination indicated the presence of double primary cancer, consisting of hepatic cholangiocarcinoma and thyroid carcinoma. Biopsy of the osteolytic lesion showed a metastatic adenocarcinoma of unknown origin. Subsequently, final diagnosis was confirmed by I-131 scan and liver lesion biopsy. The patient received positive multidisciplinary treatments and survived for 9 months following diagnosis. The results of the present case suggest that multiplicity of primary malignancy is not necessarily an indicator of poor prognosis, as long as effective diagnosis and adequate disease management are achieved.

    The breast is an uncommon site for metastases. Nevertheless, it is important to differentiate primary from secondary tumors of the breast, because clinical management and expected outcomes are vastly different. We report two examples of tumors with a papillary histologic pattern metastasizing to the breast. One of the cases occurred in a 31-year-old woman with a primary renal cell carcinoma, the other was in a 42-year-old woman with an ovarian papillary serous adenocarcinoma. In the first case, the patient's previous history of cancer was not known to the pathologist. The cases highlight the difficulty in distinguishing primary from metastatic tumors in the breast. In both cases the tumors infiltrated in a pattern that mimicked in situ ductal carcinoma changes. Additionally, in both cases, the metastasizing tumor was unusual with the tumor cells diffusely permeating the lymphatic spaces, not in a solid mass. These cases and a review of the literature indicated that breast metastases, although rare, must be recognized and differentiated from primary breast tumors to avoid unnecessary radical surgery to the breast. Moreover, the presence of changes similar to in situ carcinoma of the breast are not conclusive evidence that one is evaluating a primary breast carcinoma. When there is any unusual histomorphology, a good degree of suspicion is necessary. Ann Diagn Pathol 5:15-20, 2001. PMID:11172202

    Postirradiation osteosarcoma of the maxilla was seen in four Hong Kong Chinese patients treated for nasopharyngeal carcinoma. These cases represent four of 42 (9%) cases of osteosarcoma at all sites in this institution during the period 1979 to 1989, when more than 1000 patients were treated with radiotherapy for nasopharyngeal carcinoma. The latent periods varied from 8 to 11 years from completion of radiotherapy treatment to development of osteosarcoma. The radiation dosage varied from 6000 to 6280 cGy in three of the patients. These cases fit the criteria for diagnosis of postirradiation sarcomas. Maxillary osteosarcomas after irradiation for nasopharyngeal carcinoma do not appear to have been described. The very high incidence of nasopharyngeal carcinoma (for which radiotherapy is the treatment of choice) in Hong Kong Chinese would make the occurrence of such tumors more likely in Hong Kong, although the small risk does not contraindicate the use of radiation in the treatment of nasopharyngeal carcinoma in view of its well-documented efficacy.

    Pregnancy-associated breast cancer is the most common solid tumor in pregnancy after cervical carcinoma but still has a low incidence. It has been associated with a poor prognosis; though based on a limited number of retrospective case-control studies, some authors have reported no differences from that of non-pregnant patients. There is no consensus about the treatment; it requires an interdisciplinary approach and it is necessary to balance between the benefit for the mother and risk for the fetus. Each case requires an individual decision taking into account the stage of disease, patient preferences and gestational age. Above chemotherapy, it is only recommended after the first trimester of pregnancy and anthracyclin-based schemes have the higher evidence, but taxanes are also considered as an alternative in patients who do not respond to anthracyclines or its use is contraindicated. For the time being, there is a lack of data, and clinical decisions are based on small retrospective cohorts, case-control studies and case reports. We report two cases of patients being diagnosed with breast cancer while being pregnant and treated with surgery and chemotherapy, including anthracyclines, during the second and third trimester of pregnancy. In both reported cases, childbirth was induced before the 37th week of gestation and only one presented low birth weight with no more complications. The echocardiogram monitorization showed normal cardiac function in mothers and fetus. PMID:26018968

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

    In 2013, a 76-year-old male with a cardiac pacemaker was diagnosed with adenosquamous carcinoma of the duodenum. Subsequently, a pancreatoduodenectomy and lymph node dissection were performed, and 12 cycles of adjuvant chemotherapy (modified FOLFOX6 regimen), which consisted of fluorouracil, leucovorin and oxaliplatin, were administered via a central venous catheter. At 5 months after the completion of adjuvant chemotherapy, the patient experienced the sudden onset of severe pain at the back right of the ear, edema of the right side of the face and right jugular vein dilatation. Computed tomography (CT) revealed filling defects in the superior vena cava (SVC) and right brachiocephalic vein, indicating catheter-induced venous thrombosis. Although the catheter was removed and anti-coagulation therapy, aspiration of the thrombosis and ballooning dilatation were performed immediately, the patient's symptoms were not ameliorated. Notably, histological examination following thrombus aspiration revealed metastatic cancer cells, and fluorodeoxyglucose-positron emission tomography/CT identified metabolically active nodules in the SVC at locations consistent with the initial duodenal tumors detected by CT and in the first thoracic vertebrae. The tumor thrombus rapidly increased in size and resulted in worsening dyspnea. Subsequently, radiotherapy was performed, followed by chemotherapy, which relieved the systemic symptoms and suppressed the tumor growth. Adenosquamous carcinoma of the duodenum is extremely rare, and to the best of our knowledge, intraluminal SVC metastasis as a result of adenosquamous carcinoma of the duodenum has not been reported previously. The placement of a cardiac pacemaker, central venous catheter and tumor cells possessing high metastatic potential are hypothesized to have contributed to this rare case of metastasis. PMID:26870254

    The authors present an exceptional case of a transitional cell carcinoma of the uterine tube in a 59-year-old female patient, co-existing with appendicitis. Originally, the patient was assigned to surgery due to an inflamed tumour of the right adnexa. A mid-surgery diagnose revealed appendicitis by chance, but in the course of an examination of the right uterine tube, performed on the spot, no progressive carcinoid process was univocally diagnosed. Therefore, the treatments applied were a bilateral salpingectomy and appendectomy. In the course of the final pathomorphological examination, using an immunohistochemical technique, a primary cancer of the uterine tube composed of transitional epithelium cells (transitional cell carcinoma G-2, pT1a) was diagnosed. At the time of the second surgery, a radical hysterectomy, bilateral oophorectomy and omentectomy were performed and afterwards, the patient was treated with a post-operational radiotherapy. The authors support the thesis that a primary cancer of the uterine tube may, as it looks, suggest a different ailment and present diagnostic problems. PMID:16200402

    Liver predominant small cell carcinoma is rare, but often presents as hyper-acute liver failure with unknown primary and is a medical emergency. We present 2 autopsy and 7 biopsy cases of liver predominant small cell carcinoma and demonstrate that these patients present with liver failure and identifiable hepatomegaly, but lack discrete lesions on imaging, as well as no mass lesions identified in other organs including lung. Compared to the multiple nodules of metastatic small cell carcinoma in the liver, unique morphologic feature of liver predominant/primary small cell carcinoma in autopsy and biopsy specimens was a diffuse infiltration of small, blue, neoplastic cells predominantly in the sinusoidal space in the liver parenchyma. Prior to diagnosing liver predominant/primary small cell carcinoma, other infiltrating small blue cell neoplasms including lymphoma and peripheral neuroectodermal tumor need to be ruled out through immunohistochemistry (IHC). We therefore demonstrate that liver biopsy together with a rapid panel of immunostains is necessary to firmly establish a diagnosis of liver predominant small cell carcinoma and allow clinicians to immediately implement potentially lifesaving chemotherapy.

    Patients with hereditary leiomyomatosis and renal cell carcinoma (HLRCC) syndrome are prone to develop smooth muscle tumors of the uterus and skin and also renal carcinomas. The morphologic features of renal tumors that arise in the setting of HLRCC are well described, the hallmark feature being the presence of prominent eosinophilic nucleoli surrounded by a clear halo. Renal tumors associated with HLRCC are aggressive and often present late with high-stage disease. Early detection of patients with HLRCC could lead to surveillance for renal carcinomas. Women with HLRCC often present at a young age with uterine leiomyomas and frequently undergo hysterectomy as a result. HLRCC associated uterine leiomyomas show nuclear features similar to those described in HLRCC associated renal tumors. Therefore, presence of these nuclear features in uterine smooth muscle tumors may aid in early detection of HLRCC, resulting in surveillance for renal carcinoma. We present a case of a 32-year-old woman who underwent hysterectomy for uterine fibroids and subsequently presented 5 years later with high-stage renal carcinoma. Histologic evaluation of uterine leiomyomas and renal carcinoma revealed identical nuclear features, that is, prominent nucleoli with perinucleolar halos, raising the possibility of HLRCC. Subsequent testing confirmed a fumarate hydratase mutation. The presence of above-described nuclear features in uterine leiomyomas should raise the possibility of HLRCC. PMID:21753700

    Renal cell carcinoma is known to have blood-borne metastasis. This is usually to the bone, lungs and brain. Other unusual metastatic presentations such as skin and bowel metastasis have also been described. In most cases, the metastasis occurs as a late manifestation in a patient with known primary renal cell carcinoma. A rare synchronous presentation of skin and duodenal metastasis in an otherwise asymptomatic patient is reported here. This patient presented with a skin lesion that, on excision, brought up the diagnosis of metastatic renal cell carcinoma. While the patient was waiting for surgery, she also developed melena that, on gastroscopy, confirmed a duodenal metastasis. This case highlights the importance of early recognition of otherwise unrelated lesions as presentations for an advanced renal malignancy. PMID:22684828

    Sorafenib is a tyrosine kinase inhibitor (TKI) of the vascular endothelial growth factor receptor (VEGFR) used for advanced renal cell carcinoma. Treatment with sorafenib prolongs progression-free survival in patients with advanced clear-cell renal cell carcinoma. However, in spite of its therapeutic efficacy, sorafenib causes a wide range of adverse events. Cardiovascular adverse events have been observed when sorafenib was used with targeted agents. Although these adverse events like hypertension, reduced left ventricular ejection fraction, cardiac ischemia or infarction were manageable with standard medical therapies in most cases, some had a poor clinical outcome. We report three cases of acute myocardial infarction associated with sorafenib in patients with metastatic renal cell carcinoma. PMID:26497860

    Metastatic squamous cell carcinoma (SCC) from an unknown primary site to the colon has not been reported previously. A 75-year-old woman presented with a mass in the left submandibular region. Biopsy revealed a Class V lesion, but the histologic type was undetermined. Surgical resection of the left submandibular gland with cervical lymph node dissection was performed. However, SCC was seen in the lymph nodes only, with no tumor in the submandibular gland. Three months after surgery, computed tomography revealed that the preoperatively diagnosed lesion in the transverse colon had grown considerably. A laparoscopic right hemicolectomy was performed. Histological examination showed features of SCC, similar to the findings in the cervical lymph nodes. We report a rare case of synchronous metastatic SCC to the colon and cervical lymph nodes from a carcinoma of unknown primary site. PMID:27173884

    Despite the increase in the incidence of thyroid carcinomas, the occurrence of collision tumors in the thyroid remains a rare event. We present the case of a 69-year-old female who presented to the emergency department with a chief complaint of painful neck swelling. Imaging revealed a large right hemithyroid mass and a left hemithyroid nodule. Fine needle aspiration of the lesions and subsequent total thyroidectomy revealed a Hürthle cell carcinoma in the right lobe and bilateral multicentric papillary carcinoma foci, including 2 foci with a classical pattern and 1 encapsulated follicular variant in the isthmus. BRAF gene mutation analysis revealed V600E gene mutation in the classical variants of papillary carcinoma and in the Hürthle cell carcinoma. The focus of follicular variant of papillary carcinoma in the isthmus and a sample from normal thyroid tissue did not harbor BRAF mutations. This case is remarkable in being an unusual report of a follicular Hürthle cell carcinoma harboring the BRAF V600E mutation and occurring in collision with multifocal papillary carcinoma. Documentation of such cases is important as it helps better understand the pathogenesis, clinical behavior, and radiologic findings of such rare lesions and to determine the optimal treatment modalities.

    Introduction Clear cell renal cell carcinoma (ccRCC) is well known for its propensity to metastasize to unusual sites, even after 10 years. Gallbladder metastases are extremely rare, being found in approximately 0.6% of cases, at autopsy. Case presentation A 51-year-old man with a history of right ccRCC underwent total nephrectomy with extended lymphadenectomy, in another Hospital. Three years later, he was hospitalized at our Hospital, with gallbladder metastasis detected during a follow-up CT scan. At clinical examination, the patient did not present any symptoms or signs of gallbladder disease. Several imaging tests were performed to better characterize the lesion. A successful cholecystectomy and hepatic resection of 4b segment were performed, obtaining a R0 resection. The clinical course was uneventful, without any complications. After a 7-month follow-up, the patient is free from disease. Discussion A typical metastases are those located in a site other than thoracic, skeletal, hepatic, adrenal or encephalic tissue. Cholecystectomy with R0 resection has demonstrated to be the only factor increasing survival, mainly in isolated cases of metastasis, providing an overall 35–60% survival rate at 5 years. Conclusion In the follow-up of patients with a positive history of renal cell carcinoma specially clear cell subtype, all new finding should be taken into account as possible metastases. We ought to consider US and CT-scan behavior of gallbladder metastatic disease in order to orientate our diagnosis. Surgery for metastatic gallbladder disease of renal origin seems to be a feasible therapy which is capable of increasing patients’ overall survival. PMID:26688513

    Nasopharyngeal carcinoma is an uncommon cancer in North America. Its clinical course is typified by locally advanced disease at diagnosis and has a high propensity for both regional and distant spread. It is, therefore, typically treated with a combination of radiation and chemotherapy. This report describes our 10-year clinical and radiological findings in a 48-year-old Vietnamese male patient with locally-advanced T4N1M0 lympho-epithelial carcinoma of the nasopharynx. Despite a long remission period after his initial course of aggressive chemoradiation, his tumor recurred locally after 4 years. Thereafter, throughout a period of over 10 years, he has been treated with multiple courses of re-irradiation and three different trials of chemotherapy. He was ultimately provided with over 30 months of progression-free tumor control with the epidermal growth factor receptor (EGFR)-inhibitor cetuximab. This case illustrates the commonly protracted course of this disease and its responsiveness to multiple treatment modalities. PMID:19527509

    The patient was a 75 year-old male. Noticing areas of hardening in the lower abdomen, and consequently feelings of systemic fatigue and difficulty in walking, the patient visited a clinic and was diagnosed with kidney failure prior to the visit to our clinic. Computed tomography and magnetic resonance imaging showed thickness of the rectus abdominis muscle and the bladder wall, and bilateral hydronephrosis was also identified. As no explicit tumor was identified in the bladder, the patient underwent biopsies of the abdominal wall and bladder membrane mucous, and was diagnosed with a plasmacytoid urothelial carcinoma primarily developed in the bladder. The patient displayed a poor general state of health and died five months after the diagnosis. It is known that plasmacytoid urothelial carcinomas progress rapidly and the prognosis is poorer than for the micropapillary variant. It is important to obtain a tissue specimen in the early stage of this disease because there are cases in which no explicit tumor can be identified. Furthermore, the value of carbohydrate antigen (CA) 19-9 of the patient was much higher than would be expected as normal at the first visit. It kept rising during the follow-up and was useful as a marker to indicate the progress of the disease. PMID:27018411

    Reactive lymphoid hyperplasia is a rare disease that forms a mass-like lesion and is characterized by the proliferation of non-neoplastic, polyclonal lymphocytes forming follicles. We recently encountered 2 cases of reactive lymphoid hyperplasia of liver, both of which were asymptomatic and mimicked hepatocellular carcinoma by various imaging modalities. Based on the clinical impression of hepatocellular carcinoma, surgical resections were performed. Microscopic findings revealed that both lesions consisted of an aggregation of lymphocytes consisting of predominantly B-cells, with multiple lymphoid follicles positive for CD10 and negative for bcl-2, consistent with the diagnosis of reactive lymphoid hyperplasia. Polyclonality of both lesions was further confirmed by B cell receptor gene rearrangement study. The incidence of reactive lymphoid hyperplasia in the liver is exceedingly rare, and it is difficult to differentiate such lesions from hepatic malignancies based upon clinical grounds. The clinicopathological findings and literature review of this report may be helpful to improve the clinical decision-making. PMID:26191310

    Parathyroid carcinoma (PTCA) is a rare disease, and ectopic PTCA is particularly rare. Parathyroid hormone-related protein (PTHrP) expression in PTCA has not been previously described in the relevant literature to the best of our knowledge. The present study reports a unique case with a mediastinal parathyroid carcinoma producing parathyroid hormone (PTH) and PTHrP. A 53-year-old man presented with hyperparathyroidism symptoms, including fatigue, chest pain, dizziness, muscular soreness, polyuria, night sweats and renal stones. However, neck ultrasound revealed no significantly abnormal thyroid or parathyroid nodules. Tc99m methoxyisobutylisonitrile (Tc99m-MIBI) scintigraphy scanning indicated an ectopic mediastinal parathyroid adenoma. Histopathological examination revealed PTCA, and the tumor tissue was coproducing PTH and PTHrP. The patient underwent successful surgical operation. Serum calcium and PTH levels remained within normal ranges, and there was no tumor recurrence observed at a 3-year follow-up appointment. Although rare, ectopic parathyroid glands may lead to malignant disease. Clinical symptoms, biochemical tests, ultrasound and Tc99m-MIBI scintigraphy scanning may assist with the diagnosis of this disease. Hypersecretion of PTHrP and PTH contributed collaboratively to the pathogenesis of hypercalcemia due to PTCA. Complete surgical resection with microscopically negative margins is the recommended treatment for PTCA and offers the best chance of a cure. PMID:27313750

    Struma ovarii (SO) is a slow-growing ovarian neoplasm with thyroid tissue as its predominant component. It is an uncommon neoplasm, usually asymptomatic with an unknown risk of malignant transformation. Due to difficulties in assessing the rare biological nature and the discrepancies in the reported cases, a consensus on the appropriate treatment has not been definitively reached. A 50-year-old female was subjected to upper gut endoscopy which showed a 30-mm mass located in the gastric antrum, suggestive of mesenchimal tumor. Incidentally, a pelvic CT scan also documented a solid mass in the right adnexa, with morphological characteristics of ovarian neoplasm. The patient underwent gastrectomy, total hysterectomy, bilateral salpingo-oophorectomy with lymph node dissection, and omentectomy. Histology documented the presence of gastric cavernous angioma, and, in the right adnexa, foci of follicular thyroid-type carcinoma arising in SO with a well-differentiated neuroendocrine component.Here we report and discuss the clinical and morphological presentation of follicular thyroid-type carcinoma arising in SO. The neoplasm was discovered incidentally and had a favorable clinical outcome at 1-year follow-up. PMID:22613573

It is an uncommon neoplasm, usually asymptomatic with an unknown risk of malignant transformation. Due to difficulties in assessing the rare biological nature and the discrepancies in the reported cases, a consensus on the appropriate treatment has not been definitively reached. A 50-year-old female was subjected to upper gut endoscopy which showed a 30-mm mass located in the gastric antrum, suggestive of mesenchimal tumor. Incidentally, a pelvic CT scan also documented a solid mass in the right adnexa, with morphological characteristics of ovarian neoplasm. The patient underwent gastrectomy, total hysterectomy, bilateral salpingo-oophorectomy with lymph node dissection, and omentectomy. Histology documented the presence of gastric cavernous angioma, and, in the right adnexa, foci of follicular thyroid-type carcinoma arising in SO with a well-differentiated neuroendocrine component. Here we report and discuss the clinical and morphological presentation of follicular thyroid-type carcinoma arising in SO. The neoplasm was discovered incidentally and had a favorable clinical outcome at 1-year follow-up. PMID:22613573

    Introduction. Orbital myiasis is the infestation of the orbital tissues by fly larvae or maggots. Compromise of periorbital tissues by malignant disease, surgery, ischemia, or infection may predispose the patient to orbital myiasis. Case Report. A 73-year-old male patient with neglected recurrent basal cell carcinoma of the eyelid invasive into the orbit presented with complaints of intense itching and crawling sensation with maggots wriggling and falling from the wound of left orbit. The patient improved following manual removal of the maggots along with oral Ivermectin treatment. Recurrence of the basal cell carcinoma was confirmed by punch biopsy from the wound and extended exenteration of the orbit followed by reconstructive surgery was done. Conclusion. Orbital myiasis is a rare and preventable ocular morbidity that can complicate the malignancies resulting in widespread tissue destruction. The broad spectrum antiparasitic agent, Ivermectin, can be used as noninvasive means to treat orbital myiasis. In massive orbital myiasis and those associated with malignancies, exenteration of the orbit must be seriously considered. PMID:27595028

    A woman in her 50s complained of dysphagia and was diagnosed with locally advanced esophageal cancer in the middle and upper thoracic esophagus, invading the tracheal bronchus. The biopsy indicated esophageal basaloid squamous carcinoma. The pretreatment diagnosis was cT4N2M0, cStage Ⅳa. She was treated with systemic chemotherapy consisting of FAP (5-fluorouracil [5-FU], doxorubicin [DXR] and cisplatin[CDDP]), which resulted in significant tumor shrinkage. One year later, the tumor regrew, and nedaplatin (CDGP) plus docetaxel (DOC) was administered as second-line chemotherapy. The patient complained of dysphagia during the course of chemotherapy, and received radiation therapy for the residual tumor, which again significantly shrunk. Four years after the first round of chemotherapy, the patient can take oral nutrition, and is continuing to undergo chemotherapy. This is a case of long-term survival of locally advanced esophageal cancer of basaloid squamous carcinoma. Effective chemotherapy and radiation can improve the treatment outcome. PMID:26805208

    Background Bardet-Biedl syndrome is a rare disorder characterized by retinal dystrophy, obesity, kidney dysfunction, polydactyly, hypogonadism and cognitive impairment. It can be accompanied by systemic findings such as malignancy, hypertension, diabetes mellitus, constitutional and functional disorders of urogenital system and liver fibrosis. Case report A 35-year-old woman with Bardet-Biedl syndrome was referred to our outpatient nephrology clinic with dysuria, acute renal failure, and urinary tract infection. A sized 2 x 1 cm mass between labia major and minor was noted, while CT scan showed a lesion that encompassed uterus and extended to the posterior side of the bladder in the left adnexal region and a 3 cm lesion in the liver. Excisional biopsy of the mass revealed a well-differentiated, squamous cell carcinoma. Dysuria resolved with insertion of urinary catheter after bougie dilatation and the patient was referred for radiotherapy. Conclusion It should be kept in the mind that renal failure may develop due to constitutional urogenital anomalies such as vulva carcinoma. This can be an important cause of morbidity and mortality in patients with Bardet-Biedl syndrome.Hippokratia 2015; 19 (2):176-178.

    We report a rare case of esophageal carcinoma with an aberrant right subclavian artery. A 67-year-old woman was admitted to our hospital because of a sense of discomfort during swallowing. A detailed gastrointestinal examination revealed advanced carcinoma of the middle thoracic esophagus. Preoperative CT also revealed an aberrant right subclavian artery (AR SA). After the second course of neoadjuvant chemotherapy (FP therapy), we conducted a transthoracic esophagectomy with a 3-field lymphadenectomy. The right recurrent nerve was not identified at the right subclavian artery during mediastinal dissection, but the non-recurrent inferior laryngeal nerve (NRILN) was identified as going directly from the vagal nerve to the larynx during the neck lymphadenectomy. The thoracic duct ran between the esophagus and the azygos vein, terminating at the right venous angle. We were able to perform a #106recL lymphadenectomy as usual. She continues to do well without signs of recurrence 1 year later. Though ARSA is a relatively rare congenital anomaly, it must be identified preoperatively, and anatomical anomalies such as NRILN must be taken into consideration, in order that the operation can be performed safely.

    Synchronous double malignancies of gastric carcinoma (GC) and malignant lymphoma (ML) are rare and very difficult to treat. We report a case of synchronous GC and nodal ML, regarding which clinical and pathological features and treatment are discussed. A 68-year-old woman with a history of inguinal hernia was admitted for abdominal pain and high fever and subsequently underwent herniorrhaphy, but the fever remained. Computerized tomography showed a stomach mass and multiple enlarged lymph nodes in the abdominal cavity and inguinal regions. Gastric adenocarcinoma coexistent with advanced in situ follicular lymphoma was confirmed by endoscopy, biopsy of inguinal lymph nodes and bone marrow examination. Two chemotherapy regimens, R-CHOP (rituximab, cyclophosphamide, perarubicin, vincristine and prednisone) and systemic therapy (5-fluorouracil and calcium folinate) combined with regional perfusion (oxaliplatin and etoposide) through the left gastric artery were performed at intervals against ML and GC, respectively. Partial remission in both tumors was achieved after 4 courses of treatment, but the patient finally died of heart failure. Scrupulous biopsy of non-draining lymph nodes in patients with gastrointestinal carcinomas is supposed to improve the diagnostic rate of simultaneous nodal ML. The interval chemotherapy strategy with two independent regimens is beneficial for such patients, especially for those unable to tolerate major surgery. PMID:20740201

    A case of brain metastasis from peritoneal serous surface papillary carcinoma (SSPC) was reported. This 68-year-old woman was admitted to our department because of decreased consciousness level for the last few days. Her medical past history revealed breast cancer and SSPC of the peritoneum at the age of 64. On admission she was comatose and irritable. Serum and urine examination revealed the syndrome of inappropriate secretion of antidiuretic hormone that was treated with strict restriction of water intake. MRI of the brain demonstrated a nonspecific mass in the subcortical area of the right superior parietal lobule. The mass was successfully removed in en bloc fashion. Pathological diagnosis was SSPC that was compatible with the previous diagnosis obtained from the peritoneum four years previously. Although the patient received whole brain radiation therapy postoperatively, her condition deteriorated rapidly. She died four months after brain surgery. SSPC of the peritoneum is a rare malignant tumor that is defined as a primary tumor histologically indistinguishable from serous carcinoma of the ovary, diffusely involving the peritoneal surface but sparing or only superficially invading the ovaries. Because of the prolongation of survival resulting from advanced chemotherapy for SSPC of the peritoneum, more patients live long enough to develop brain metastasis. Therefore, SSPC of the peritoneum should be kept in mind in the differential diagnosis of a primary site for brain metastasis. PMID:21628741

    We report on a 61-year-old woman with a history of right-sided nephrectomy for clear cell renal cell carcinoma (RCC) occurring 21 years ago; she currently presented with a bilateral ovarian tumour. Histologically, the tumour of both ovaries was clear cell carcinoma. Immunohistochemically, the tumour cells were positive for vimentin, RCC marker, epithelial membrane antigen, cytokeratin AE1/3 and CD10. Cytokeratin 7, CA125, HMWCK, estrogen and progesterone receptors were all negative. Based on the morphology and immunophenotype of the tumour, we established a diagnosis of late metastasis of RCC in the ovaries. A postoperative abdominal computed tomography scan, however, revealed a tumour mass solely in the left kidney, which had not been visible in the preoperative ultrasound. The patient underwent nephron-sparing surgery and a biopsy showed the tumour to be clear cell RCC. Metastasis of RCC to the ovaries is rare, and to the best of our knowledge, only 24 cases have been reported to date. However, due to the different treatments and prognosis, the distinction between a primary ovarian tumour and metastasis of RCC is important. PMID:24678363

    Both gastric adenocarcinoma of fundic gland type (ADC-FG) and carcinoma with lymphoid stroma (lymphoepithelioma-like carcinoma, LELC) are relatively rare. Epstein-Barr virus (EBV) has been implicated in the pathogenesis of LELC. However, the pathogenesis of ADC-FG, as well as the role of EBV in the carcinogenesis of LELC, remain unclear and under debate. The current study presents a case of concurrent ADC-FG and LELC in the stomach in a 69-year-old man. Total gastrectomy was performed, and two separate masses were identified. Upon histological and immunohistochemical examination, the mass located in the lower body was determined to be LELC and the mass in the upper body was diagnosed as ADC-FG. The lesions were characterized by different mucin phenotypes and EBV in situ results. In the lower-body mass, EBV in situ hybridization expression was diffusely strongly positive, but MUC2, MUC5AC, MUC6, and CD10 were all negative. On the other hand, in the upper-body mass, the results were positive for MUC6 but negative for MUC2, MUC5AC, CD10, and EBV by in situ hybridization. The remaining gastric tissue was unremarkable, and perigastric lymph node metastases were absent. Seven months after the gastrectomy, a postoperative computed tomography scan revealed no recurrence or metastasis. PMID:27462199

    The nevoid basal cell carcinoma syndrome, or Gorlin-Goltz syndrome, is an autosomal dominant multiple system disorder with high penetrance and variable expressions, although it can also arise spontaneously. The diagnostic criteria for nevoid basal cell carcinoma syndrome include multiple basal cell carcinomas, palmoplantar pits, multiple odontogenic keratocysts, skeletal anomalies, positive family history, ectopic calcification and neurological anomalies. We report a brother and sister who were both diagnosed with nevoid basal cell carcinoma syndrome. PMID:27303197

    We herein described two cases of adenomyoepithelioma (AME) with carcinoma of the breast. Both of them were Japanese women, and they presented with a mass in their breast. Post-operative specimens revealed encapsulated and well-circumscribed tumors with local invasion, necrosis, cytological atypia, and a high mitotic rate. In immunohistochemistry, coincidentally with the loose adhesion pattern of myoepithelial cells in both cases, the intensities of E-cadherin and beta-catenin were much weaker in myoepithelial than luminal epithelial cells, with almost negative finding of beta-catenin in one case. We first found deletion of CDH1 and polysomy of CEP16 in myoepithelial cells by double color-fluorescence in situ hybridization. The two cases have been followed up for 5-8 years, and both remained free from local recurrence and distant metastases. We also presented an overview of 47 cases of AME with carcinoma in English-language literatures. PMID:26596263

    Spindle cell carcinoma (SpCC) is referred to as a variant of oral squamous cell carcinoma. It is also known as "sarcomatoid squamous cell carcinoma" because it consists of normal squamous carcinoma cells with spindle-shaped cells that appear similar to a sarcoma. The term, "second primary tumor" (SPT) or "double primary tumor", is proposed for a second tumor that develops independently from the first. SPTs can present as either synchronous or metachronous lesions. Synchronous SPTs are defined as tumors occurring simultaneously or within 6 months after the first tumor. The patient in this case, whose primary tumor was in the tongue, was diagnosed with SpCC with metastases to both neck lymph nodes. This case also exhibited a second primary cancer as a synchronous lesion in the thyroid gland, which is uncommon. All carcinomas, both in the tongue and thyroid gland, were removed surgically, and especially in the tongue, an anterolateral thigh free flap was performed successfully to replace the defect.

    Chylothorax is the accumulation of lymph fluid in the pleura. Gastric carcinoma with chylothorax and lymphedema as the initial manifestations has rarely been reported, with only 14 cases reported to date. The mechanisms of gastric carcinoma generating chylothorax have not yet been determined. The current study reports the case of a 63-year-old woman presenting with chylothorax and lower extremity lymphedema, and reviews the existing literature. A chest radiograph performed on the present patient revealed large pleural effusion and chylothorax was diagnosed. Upper gastrointestinal endoscopy identified an irregular apophysis lesion and a biopsy confirmed poorly differentiated gastric adenocarcinoma. The patient was discharged at her request, and subsequently succumbed to the disease 4.5 months later. Based on the findings of the present study, as well as those of the literature, we proposed a novel form of gastric carcinoma infiltrating the body. Chylothorax and lymphedema may be a consequence of gastric carcinoma cells infiltrating the lymphatic circulatory system; therefore, the differential diagnosis of chylothorax and lymphedema of unknown cause should consider gastric carcinoma, regardless of gastrointestinal symptoms.

    Differentiated thyroid carcinoma (DTC) is a common malignancy. The general treatments are thyroidectomy of the affected lobe along with lymphadenectomy. However, bone metastasis is rare in DTC compared with other malignancies and the management of metastasis foci is still controversial. Here we present a case of follicular thyroid carcinoma with the 6th cervical vertebra body metastasis successfully treated by total thyroidectomy, cervical corpectomy, and internal fixation, followed by hormone replacement therapy and radioiodine therapy. Eleven additional patients diagnosed as thyroid carcinoma with bone metastasis collected from Chinese literature between January 1996 and December 2013 were also reviewed. The mean age of the 12 patients at presentation was (53.9±9.2) years (rang, 42–72 years) and the male to female ratio was 1:2. Nine cases received total/near-total thyroidectomy or lobectomy while the other three patients refused for personal reasons. The interventions for bone metastasis were one-stage operation (9/12), I131 adjuvant therapy (3/12), chemotherapy (1/12), and no intervention (1/12). During the follow-up, two patients died of metastatic carcinoma recurrence, one died of multiple organ metastasis, and one with an unknown reason. We conclude that the management of thyroid carcinoma with bone metastasis needs multidisciplinary cooperation. Surgical resection is still the first choice for cure, while the combined one-stage operation on the primary and metastatic sites followed by hormone replacement therapy and radioiodine therapy is an applicable treatment.

    Nasopharyngeal carcinoma (NPC) is a rare and distinct malignancy that arises from the epithelium of the nasopharynx. It accounts almost 1% of all pediatric malignancies. Oral complications of radiotherapy in the head and neck region are the result of the deleterious effects of radiation on salivary glands, oral mucosa, bone, dentition, masticatory musculature, and temporomandibular joints. Here we present 3 male NPC patients 13, 14 and 15 years old. One of them had stage III and the others stage IV diseases. Administered dose of radiation was 66 Gy for case I, 70 Gy for case II and 68 Gy for case III. The follow-up period was more than 12 months except for case III and all of them were disease free in their last visit. All attended dental clinics for dental and TMJ problems. Dentitions were severely affected, trismus and severe xerostomia. Long-term effects of radiotherapy which has a great impact on patients' quality of life and the role of supportive care and minimizing the late effects of ionizing radiation are discussed.

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

    Introduction Immunoglobulin G4-related disease (IgG4-RD) is an inflammatory condition associated with elevated serum IgG4 levels and tissue infiltration by IgG4-expressing plasma cells. We present a case of adenoid cystic carcinoma (ACC) of the submandibular gland with possible involvement of IgG4-RD. Presentation of case The patient was a 59-year-old man presenting with a swollen right submandibular gland. Laboratory tests revealed IgG4 levels of 176 mg/dl (reference range: 4.8–105). An initial open biopsy for histological diagnosis showed chronic sialadenitis. The region was monitored on an outpatient basis, and finally the right submandibular was totally resected because malignant tumor could not be excluded. Histological examination of the submandibular gland showed an ACC with lymphocytic infiltration containing many IgG4-positive plasma cells in the tumor stroma. Discussion We have described a case that indicated a possible involvement of ACC with IgG4-RD. This allows us to speculate that longstanding IgG4-RD may progress to malignancy or infiltration of IgG4-positive plasma cells through the signals of tumor stimuli. Further investigations are required to determine the potential pathogenic mechanism underlying this unique tumor. Conclusion This case underscores that caution is needed in the diagnosis of masses with high serum IgG4 levels, as the differential diagnosis includes malignancy. PMID:25781921

    A 79-year-old male was referred to the Department of Gastroenterology in our hospital due to a large palpable abdominal mass, with the suspicion of a gastrointestinal stromal tumor. An abdominal computed tomographic (CT) scan revealed a huge mass of 270×208×144 mm which occupied the entire pelvic cavity. Since the specimens obtained by an endoscopic ultrasound-guided fine-needle aspiration via lower intestinal tract revealed a Gleason score 4+4 prostate adenocarcinoma, he was then referred to our department. Prostate specific antigen (PSA) was elevated to 3,087 ng/ml, and positron emission tomography-CT revealed right obturator lymph node metastasis and bone metastasis of the left 5th rib. Degarelix was administered as an androgen deprivation therapy, and the PSA level had decreased to 62.4 ng/ml one month later. At the last follow-up, the PSA level was 0.67 ng/ml and the tumorsize had decreased to 88×83×110 mm. Next, we conducted a follow-up survey by mail of 20 reported Japanese cases of a giant prostate carcinoma, and data on 17 cases were available for analysis. In the total of 18 cases, including the present case, with a median follow-up time of 26 months, the 2-year overall survival rate was 85.7% for patients without metastasis, and 65.6% forthose with metastasis.

    Thyroid-like follicular carcinoma of the kidney (TLFCK) is a provisional new entity of renal cell carcinoma (RCC). We herein reported and compared one TLFCK case and one PRCC case with thyroid-like feature. The former entirely consisted of thyroid-like follicular architecture and the tumor cells were diffusely positive for PAX-8, but negative for CK7, AMACR, and CD10. By contrast, both papillary architecture (~60%) and thyroid-like follicular architecture (~40%) were identified in the latter. Tumor cells in both histological components exhibited diffusely positive staining for PAX-8, CK7, AMACR, but negative for CD10. FISH analysis showed no aberration in TLFCK case but trisomy of chromosome 17 in PRCC case. Along with a brief literature review, we presented that recognition of TLFCK is important to distinguish it from other conditions that show thyroid-like features. Additionally, a diagnosis of TLFCK should be cautiously made when papillary component is present in the tumor. PMID:26663803

    We report a 59-year-old man who developed dysesthesia in all extremities with severe loss of deep sensation over three months. A radiating radicular pain was also noted in the extremities. The nerve conduction study barely elicited sensory nerve action potentials both in the median and in the sural nerve. An extensive search for anti-neuronal antibodies including anti-Hu and anti-CV2 antibody was negetive. The biopsy specimen of an enlarged tracheobronchial lymph node revealed squamous cell carcinoma. The subsequent chemotherapy and radiation therapy for the neoplasm improved the radicular pain and the deep sensation to a moderate extent, leading to the diagnosis of paraneoplastic subacute sensory neuropathy (SSN). In general, cases with paraneoplastic SSN are associated mostly with small cell lung cancer, and quite rarely with squamous cell lung cancer. The early detection and the treatment of the primary tumor are crucial in a patient with subacute progression of sensory-dominant neuropathy. PMID:19827601

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

    The gold standard management for ureter transitional cell carcinoma (UTCC) is radical nephroureterectomy with excision of the bladder cuff. However, some patients cannot undergo this procedure for several reasons. In the case reports described herein, we performed stereotactic body radiotherapy (SBRT) on three patients with inoperable or surgery-rejected localized UTCC. Two out of the three patients did not develop local recurrence or distant metastasis during the observation period. However, recurrence was detected in the bladder of one patient 22 months after the treatment. No acute or late adverse events occurred in any of the three patients. SBRT may become one of the treatment options for inoperable or surgery-rejected UTCC patients. PMID:26442166

    Large cell neuroendocrine carcinoma (LCNEC) in the biliary system is a poorly differentiated, high-grade neuroendocrine tumor. These tumors exhibit aggressive behavior and an increased tendency for early nodal and distant metastases. Herein, we report an unusual case of a pure primary LCNEC of the common bile duct (CBD). A 75-year-old female presented with nausea and jaundice. The patient underwent a CBD excision with lymph node dissection. Upon histological and immunohistochemical examination, the tumor exhibited pure large cell-type neuroendocrine features. Metastases were noted in two of the eight lymph nodes. The patient was administered adjuvant chemotherapy. The patient’s cancer recurred 7 mo after surgery, and the patient died from liver failure 5 mo after recurrence. The prognosis of LCNEC of CBD remains poor despite curative resection and adjuvant chemotherapy. The role of additional therapies, such as multimodal treatment including radiation therapy, must be further studied to improve the prognoses of patients. PMID:25548506

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

    Hydrosalpinx in postmenopausal woman is rare. Most commonly it is due to primary ovarian malignancy with fallopian tube involvement or primary fallopian tube carcinoma. But hydrosalpinx with no malignancy in the fallopian tube, associated with synchronous malignancy of ovary and endometrium is rare. In a postmenopausal women, hydrosalpinx is commonly due to fallopian tube malignancy or rarely pelvic inflammatory disease. We present a rare and very interesting case of 65-year-old nulliparous postmenopausal women with bilateral hydrosalpinx and pyometra who was found to have papillary serous adenocarcinoma of the ovary and endometroid adenocarcinoma of endomertrium with normal fallopian tube. One should always suspect genital malignancy with this presentation, especially in this age group.

    The present study reports two cases of mandibular metastasis from hepatocellular carcinoma (HCC), including the clinical presentation, and computed tomography (CT), histopathology and immunohistochemistry results. Space-occupying lesions occurred unilaterally as an initial mandibular manifestation. HCC metastasis was confirmed by post-surgical examination, and the primary tumor was found using CT scans. Hepatitis B virus infection history and positive results of hepatitis B surface antigen, hepatitis B e-antibody, hepatitis B core antibody and hepatitis B virus pre-S1 antigen further supported the pathogenesis of HCC. Based on the clinical findings, the characteristics of the CT scans and the histopathology and immunohistochemistry results, the mechanisms of HCC metastasis and its management are also discussed.

    We describe the case of a 96-year-old woman who presented with a large fungating squamous cell carcinoma on her neck. In the Western hemisphere, it is rare to see patients with advanced tumours at their first presentation. We summarise the events leading to her late presentation to the hospital and explore the contributing factors. These may have included avoidance behaviour secondary to fears and misconceptions about cancer treatment. We conclude that healthcare professionals should be aware of these factors, and every effort should be made to address hidden fears and misconceptions when caring for patients with terminal illnesses. This will allay the patients' anxiety, thereby enabling them to make an informed choice about their future care. PMID:26843996

    Irreversible electroporation (IRE) is a novel image-guided ablation technique that is increasingly used to treat locally advanced pancreatic carcinoma (LAPC). We describe a 67-year-old male patient with a 5 cm stage III pancreatic tumor who was referred for IRE. Because the ventral approach for electrode placement was considered dangerous due to vicinity of the tumor to collateral vessels and duodenum, the dorsal approach was chosen. Under CT-guidance, six electrodes were advanced in the tumor, approaching paravertebrally alongside the aorta and inferior vena cava. Ablation was performed without complications. This case describes that when ventral electrode placement for pancreatic IRE is impaired, the dorsal approach could be considered alternatively. PMID:25288173

    Extrahepatic metastasis of hepatocellular carcinoma (HCC) is not infrequently found during the later stage, regarding that the autopsy report described its prevalence to be up to 50%. The most frequent sites are known to be the abdominal lymph nodes, lung and bone. However, metastasis to the nasal cavity and paranasal sinuses has been seldom reported, and to out knowledge, there is no Korean report describing extrahepatic metastasis of HCC to these sites. Recently we experienced a case of extrahepatic metastasis of HCC to the nasal cavity in a 50 year-old man with massive epistaxis refractory to conservative treatment. He was found to have a mass of soft tissue attenuation occupying the right nasal cavity at CT, which was biopsy-proven as metastatic HCC. Epistaxis was successfully treated by transcatheter arterial embolization. PMID:15385718

    A case of metastatic renal cell carcinoma (RCC) to the mandible is reported. A 22-year-old man consulted us for hypoesthesia of the right lower lip. Panorama X-ray film showed a radiolucent lesion in the right mandibular body. A diagnosis of a metastatic tumor to the mandible from the right kidney was made after evaluation by computed tomography and bone scan with Tc99 methyl diphosphonate which also revealed multiple bone metastases. Histologically diagnosis was clear cell variant of RCC. Patient has been put on radiotherapy for symptomatic treatment and a molecularly targeted drug. The therapy effectively stopped the progressive growth of oral and other metastatic lesions. The quality of life is relatively well maintained with tolerable adverse effects. The patient is still on our follow-up with an improved quality of life.

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

    Seborrheic keratoses (SKs) are common epidermal tumors composed of benign keratinocytes. Malignant skin tumors including basal cell carcinoma (BCC) rarely arise within SKs. We report a rare case of an 82-year-old man with nodulocystic BCC that appeared at the center of a scaly hyperpigmented SK that had been presented for more than 10 years. It was histologically confirmed that CK19-positive BCC arose directly from the wall of the pseudohorn cyst, a part of the SK. Nodular and/or cystic BCC also rarely arise within SKs while the most common histologic type of BCC within SKs is the superficial type. Careful observation of SKs is important even though it is rarely a background condition for malignant transformation. PMID:27512194

    69-year-old woman underwent left nephroureterectomy for left ureteral cancer (urothelial carcinoma (UC), high grade, pT3pN0) in September 2013. She returned to our hospital presenting with asymptomatic macrohematuria in July 2014. Cystoscopy showed tiny papillary tumors in the bladder. We also found genital bleeding from multiple papillary tumors on the vaginal wall. We performed transurethral resection of the bladder tumor and a biopsy of the vaginal wall demonstrated non-invasive UC, high grade. Pelvic magnetic resonance imaging after the operation showed no infiltration outside the bladder wall and vaginal wall. Therefore, we performed endoscopic excision of the vaginal tumor. However we could not resect all vaginal tumors. Irradiation of the vagina and uterus was performed under the diagnosis of metastasis of UC tovagina. Vaginal UC is extremely rare and this is the 26th case report in the literature. PMID:27018410

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

    Colorectal tumors are rare in the developing countries but common in the civilized world. With the event of westernization of the diet, the incidence is increasing in the developing countries such as Nigeria. Caecal tumors present late because of the anatomical features of this part of colon. The tumors in the caecum are insidious in onset and often attend large size. Barium enema and colonoscopy have limitation in accessing this region. Computed tomography (CT) scan is expensive and not readily affordable in the developing world. High index of suspicion is therefore necessary to the diagnosed carcinoma of the caecum as it is a curable disease if diagnosed early and treated. We present 3 cases of caecal tumors seen over a 5-year period that were treated with good outcome. PMID:24765303

    A 63-year-old man was admitted with left pleural effusion, and an amylase level of 30994IU/l. A diagnosis of pancreaticopleural fistula was made, based on the findings of magnetic resonance cholangiopancreatography and endoscopic retrograde pancreatography (ERP). After the placement of an endoscopic naso-pancreatic drainage tube, the pleural effusion markedly reduced. When ERP was performed for internal drainage, the main pancreatic duct and stricture were biopsied and showed pancreatic ductal adenocarcinoma histologically. CT revealed a mass in the head of the pancreas. He underwent pylorus-preserving pancreaticoduodenectomy. To the best of our knowledge this is the first case of pancreatic carcinoma presenting as pancreaticopleural fistula with pancreatic pleural effusion. Clinicians should pay attention to the possible presence of cancer and pancreaticopleural fistula in patients with pancreatic pleural effusion. PMID:20460853

    Myoepithelial carcinoma (MEC) of the vallecula is relatively rare, and there is no specific surgical guideline for resecting MEC in the vallecula. To the best of our knowledge, the current study reports the first case of MEC involving the vallecula of a 48-year-old female patient. In the present study, the lesion was correctly diagnosed as MEC and successfully managed using lateral pharyngotomy and by the construction of a sternohyoid myofascial flap. The patient was free of local recurrence or metastasis 18 months after surgery. The present study briefly reviews the current knowledge concerning the diagnosis and treatment of MECs in the head and neck area and offers suggestions for managing MEC in the vallecula. To conclude, MEC of the vallecula may be successfully managed by surgical treatment without evident post-surgery complications. PMID:27123078

    Neoplastic meningitis from breast cancer often leads to a progressive neurologic deterioration followed by fatal outcome. The therapy is based on the administration of high dose systemic chemotherapy with drugs able to pass through the blood-brain barrier, such as methotrexate (MTX) and cytarabine, cranial or craniospinal irradiation, and intrathecal (IT) administration of MTX and/or cytarabine. However, these approaches only have modest efficacy and are associated with side effects for the patients. A depot formulation of liposomal cytarabine (DepoCyte) has proven to be useful in clinical trials. We describe the case of a woman with a diagnosis of leptomeningeal carcinomatosis from breast carcinoma who presented cerebrospinal fluid normalization and prolonged complete MRI response to intrathecal chemotherapy with liposomal cytarabine (DepoCyte).

    Background and Objectives Many studies have shown a negative association between the consumption of soy products and the risk of some cancers, but little is known about the effect of soy consumption on nasopharyngeal carcinoma. We assessed the association between the consumption of soy products on nasopharyngeal carcinoma risk in Chinese individuals. Methods This case-control study included 600 (448 males and 152 females) incident cases of nasopharyngeal carcinoma, and an equal number of controls, matched according to gender, age (± 3 y) and household type to the nasopharyngeal carcinoma cases. All subjects were recruited from hospitals in Guangzhou, China. A face-to-face interview was conducted with each study individual to collect general information and habitual dietary intake using a 78-item quantitative food-frequency questionnaire. Odds ratios and their 95% confidence intervals were estimated using conditional logistic regression analyses. Results The median intakes of soy foods (in protein) were 0.5/0.5, 1.4/1.7, 2.7/3.3 and 6.1/7.7 (male/female) g/d in the quartiles 1 to 4. Both univariate and multivariate analyses showed no significant association between the consumption of soy proteins or soy isoflavones and the risk of nasopharyngeal carcinoma. The adjusted odds ratios (95% confidence intervals) between extreme quartiles were 0.97 (0.66-1.45) for soy proteins and 0.97 (0.66-1.42) for total isoflavones. Null associations were also observed between intake of the individual isoflavones daidzein, genistein and glycitein and NPC risk, with adjusted odds ratios for the extreme quartiles ranging between 0.73 and 1.23. Conclusion Habitual consumption of soy products had no significant effect on the risk of nasopharyngeal carcinoma in Chinese adults with a relatively low intake. PMID:24155974

    Renal cell carcinomas (RCCs) have a strong tendency to metastasize, and the most common sites are the lungs, bones and liver. Late recurrence is another feature of the RCC, with lesions appearing ≥10 years after surgical treatment. However, fibrosis has rarely been associated with the disease. The present study reports a case of recurrent RCC that manifested as a fibrotic mass within the thorax. A 48-year-old man presented with dyspnea that had persisted for 3 days. The patient had undergone a right radical nephrectomy for stage II clear cell carcinoma of the kidney 6 years previously. The patient was a current smoker, with a smoking history of 20 pack-years. Chest radiography showed pleural effusion in the right thorax with an egg-sized mass shadow within the right upper lung (RUL) field. Computed tomography (CT) showed a main mass, 7 cm in diameter, within the RUL, with heterogeneous enhancement and multiple nodules of various sizes in the lungs, suggestive of primary lung cancer or metastatic RCC. A CT-guided percutaneous needle aspiration biopsy was obtained from the main mass, but histology revealed dense fibrous tissue without any malignant cells. Positron emission tomography-CT demonstrated an irregular hypermetabolic RUL mass, with a standardized uptake value (SUV) of 5.0, along the right pleura, and small pulmonary nodules (SUV, 2.0). Ultrasound-guided biopsy was attempted for a smaller hypermetabolic pleural nodule and the result was clear cell adenocarcinoma, consistent with the previous renal histology. The present study describes the case, along with a review of the relevant literature. PMID:27313703

    Myoepithelial carcinoma (MEC) is a rare type of breast cancer composed purely of myoepithelial cells. Most often it presents with a spindle cell morphology that can mimic several benign and malignant lesions and may be misdiagnosed by the pathologist. We report 15 cases of MEC, which were sent to our consultation practice: Five of them were initially diagnosed as benign. The patients, all female, ranged from 45 to 86 years in age (mean 69.5) and-with one exception-presented with a breast mass. The tumor size measured between 1 and 4.8 cm (mean 2.6 cm). Microscopically, the tumors had infiltrative growth pattern most frequently with thin anastomosing cords of tumor cells associated with an intimately admixed reactive spindle cell stroma. The neoplastic myoepithelial cells were emanating from the myoepithelial cell layer of entrapped ductules in every case. The nuclei showed mild to moderate pleomorphism, and the mitotic activity ranged from 0 to 9/10 high power field. Immunohistochemical stains for p63, CD10, CK903, and CK5/6 reacted strongly and diffusely with the tumor cells, and mainly the reactive stroma had weak positivity for calponin, S-100, and smooth muscle actin. Estrogen receptor, progesteron receptor, and Her2 immunostains were negative, but strong epidermal growth factor receptor expression was observed. Follow-up was available for seven patients: All of them were alive at last contact; one patient had local recurrence, and one developed pulmonary metastases. MEC is a potentially aggressive malignant neoplasm sharing many features with metaplastic carcinomas. Morphologically, it is often difficult to distinguish it from benign spindle cell proliferations.

    Microwave endometrial ablation (MEA) is effective for the emergency control of uterine hemorrhage. However, to the best of our knowledge, there has been only a single report of life-threatening hemorrhage induced by endometrial carcinoma that was treated with MEA. The present report evaluates the efficacy of MEA as an emergency therapeutic option for the control of bleeding due to advanced endometrial carcinoma and minimally-invasive, early-stage endometrial carcinoma in 3 patients. MEA was able to effectively control massive uterine bleeding due to endometrial carcinoma in 2 patients with advanced disease and was curative in a patient with minimally-invasive endometrial carcinoma. Given its safety, simplicity and effectiveness, MEA may be utilized for the emergency treatment of uterine bleeding in advanced endometrial carcinoma, and may be used as a curative treatment in early-stage endometrial carcinoma.

    A 68-year-old man was introduced to our hospital for the treatment of lung and mediastinum lymph node metastases that originated from an urachal carcinoma 4 years after a partial cystectomy. First-line chemotherapy with an S-1 and cisplatin combination was ineffective. The patient received FOLFIRI plus bevacizumab chemotherapy as salvage chemotherapy. Stability was achieved after eight cycles of FOLFIRI plus bevacizumab therapy. We conducted a biopsy of the metastatic tumor, and the pathology of the biopsy tissue was partially necrotic. To our knowledge, this case represents the first report of a metastatic urachal carcinoma treated with FOLFIRI plus bevacizumab. PMID:26793485

    Carcinoma of larynx is a common disease in North Indian population. It is seen commonly in smokers and alcoholics. It poses a serious health problem due to its tendency to cause airway obstruction and to make the patient aphonic if total larynxgectomy is done for curing this cancer. We conducted a retrospective analysis in 690 cases of carcinoma larynx presenting to Nehru Hospital, Postgraduate Institute of Medical Education and Research, Chandigarh. Various aspects of this disease like predisposing factors, patterns of spread, histological types, various treatment modalities, their complications and response of this disease to these therapeutic options were studied in detail.

    Chronic lymphedema presents as interstitial fluid retention due to a failure in the lymphatic system drainage. The affected region becomes more vulnerable immunologically and predisposed to the onset of neoplasms. Basal Cell Carcinoma is the most common sort of neoplasm, nevertheless it rarely metastisizes. Sarcomas are malignant mesenchymal neoplasms, locally aggressive, which can spread. Here is reported an infrequent case of multiple basal cell carcinoma, synchronous to a poorly differentiated pleomorphic sarcoma, both spreading to lymph nodes and arising from tissue compromised by chronic lymphedema.

    Clinicians generally suspect pulmonary tumor embolism (PTE) with uncontrolled carcinomas which often spread to lungs. We, however, experienced an autopsy case of diffuse microscopic PTE despite controlled liver metastases of transitional cell carcinoma (TCC). A 66-year-old man with progressing respiratory symptoms showed almost normal chest findings on computed tomography. Although liver metastases were successfully shrunk by chemotherapy, the patient died from aggressive respiratory failure. An autopsy revealed small pulmonary vessels showing diffuse tumor emboli. TCC can cause PTE even if liver metastases are controlled. We must therefore be aware that PTE can manifest as respiratory symptoms without any computed tomography findings. PMID:27580549

    We present a case with penile and intramuscular metastases of esophageal squamous cell carcinoma. A 61-year-old male had undergone a total esophagectomy and later developed metastatic nodules of the penis and intramuscular metastasis of the thigh. We believe this is the first report of this rare case. We describe the clinical manifestation and offer therapeutic regimen; we also summarize the relevant literature. PMID:25485020

    During the past ten years, substantial progress has been made in the knowledge of the natural history of epidermoid carcinoma of the anal canal and of the response of the disease to radiotherapy alone or combined with chemotherapy. At the present time, the main problem in the management of this tumor concerns identification of the best modalities to achieve local control and preservation of anal function. From a series of 276 cases, followed for more than three years, the necessity for a careful pretreatment evaluation was stressed. This included a systematic search for pelvic metastatic lymph nodes by palpation and CT scan. All patients were treated initially by irradiation except those who underwent groin dissection for inguinal node metastasis or colostomy for complete anal obstruction. Three groups of patients have been identified: unresectable or disseminated tumors (33 cases), resectable tumors but not suitable for sphincter conservation (21 cases) treated by radiochemotherapy and delayed surgery, and resectable tumors suitable for sphincter conservation (222 cases) which were treated by a split-course regimen combining a short course of carefully planned external beam irradiation (19 days) followed by an iridium 192 implant after a two-month rest. In this group, which represents 80 percent of the whole series, 80 percent of patients have had their cancer controlled and 90 percent of controlled patients have retained normal anal function. The use of chemotherapy during the first days of irradiation is advisable in all cases to reinforce the efficacy of treatment and increase the chance of anal preservation. Results of the split-course regimen, combining external beam and interstitial irradiation, demonstrate a clear superiority over external beam irradiation alone, especially for large infiltrating tumors, which represent the majority of cases.

    To understand the pathogenesis of high-grade neuroendocrine carcinoma (HGNEC), we examined the histopathology and immunoreactivity against adenocarcinoma (AD), squamous cell carcinoma (SQ), and neuroendocrine markers in 34 cases with combined HGNEC. The 5 year overall survival rates of patients with combined small cell carcinoma (SCC) (n = 9) and combined large cell neuroendocrine carcinoma (LCNEC) (n = 25) were 33% and 75%, respectively (P = 0.011). Most of the patients were male (94%), smokers (94%), and had tumors located in the peripheral (94%) and upper lobe (65%) of the lung. Histopathologically, non-HGNEC components were predominantly ADs (65%) followed by SQs (26%). In combined HGNEC and AD, a lepidic AD component was found in 12 cases (48%). For the HGNEC components of combined HGNEC and AD, the incidence of positivity of thyroid transcription factor-1 (TTF-1) (8G7G3/1) and TTF1 (SPT24) were 64% and 91%, respectively. For HGNEC components of combined HGNEC and SQ, the incidence of positivity of 34βE12 and p63 were 22% and 11%, respectively. In conclusion, 48% of combined HGNEC and AD cases had a lepidic AD component, suggesting that HGNEC can develop in association with pre-existing AD. AD markers, but not SQ markers, were frequently retained through development of the HGNEC component. PMID:24471967

    We report a case of medullary thyroid carcinoma with a paraganglioma-like pattern and melanin production. Macroscopically, a rectangular black area within a gray-white background was seen on the cut surface of the tumor. Histologically, the tumor was found to have a trabecular or nestlike architecture with many pigmented dendritic cells, resembling the "sustentacular cells" of paraganglioma, scattered among nonpigmented polygonal tumor cells. Fontana-Masson staining and bleaching with potassium permanganate and oxalic acid revealed that this pigment was melanin, which was also confirmed by electron microscopy. Immunohistochemically, pigmented dendritic cells were positive for calcitonin, as were the surrounding typical medullary thyroid carcinoma cells. These cells were also positive for S100 protein but not for HMB-45, compatible with sustentacular cells. These findings suggest that this tumor could be considered to bridge the gap between two variants of medullary thyroid carcinoma, the melanin-producing (pigmented) type and the paraganglioma-like type.
