Granular cell basal cell carcinoma (BCC) is a rare histopathological variant of BCC, Our review of the literature revealed only 17 previously identified cases. We report the case of a 47-year-old man who presented with an ulceration on his right upper lip which was subsequently removed. Histopathologic examination revealed that the tumor was composed solely of granular cells with numerous cytoplasmic eosinophilic round inclusion bodies. Mitotic figures ranged from 8 to 15 per 10 high-power fields with a Ki-67 proliferative index approximated at 5%...

CONTEXT: - Diagnosis of malignant mesothelioma is more common in the chest than it is in the abdomen. Most published immunohistochemistry data are more applicable to pleural than to peritoneal mesothelioma. OBJECTIVE: - To clarify the practical utility of 17 immunohistochemistry markers in the differential diagnosis of peritoneal mesothelioma with an emphasis on stains for which there is either contradictory information or a paucity of literature. DESIGN: - Consultation files of peritoneal mesothelioma diagnoses rendered from 1999 to 2014 were reviewed; 242 cases are identified...

Primary large cell neuroendocrine carcinomas of the skin are exceptionally rare and can be diagnosed only when a metastasis from another organ has been excluded. We report the case of a 62 year old woman with a cutaneous papule on the mid-chest which generated a differential diagnosis of vascular lesion and basal cell carcinoma. Following excision, microscopic evaluation revealed a dermal large cell undifferentiated carcinoma, with a brisk mitotic rate and focal geographic necrosis. Mucin production was absent...

BACKGROUND: Hyalinizing clear cell carcinoma (HCCC) is a rare low-grade tumour of salivary glands that was first described as a distinct entity in 1994 by Milchgrub et al. EWSR1-ATF1 fusion was found to be specific for this tumour. The majority of the reported cases of HCCC arise from minor salivary glands within the oral cavity. Primary HCCC of the paranasal sinus is extremely uncommon. To our knowledge, only three cases have been reported in the English literature. Herein, we present a case of HCCC of the posterior ethmoid/maxillary sinus...

Despite being the largest part of the human gastrointestinal (GI) tract, the small intestine accounts for only 1-1.4% of all GI malignancies. Adenocarcinoma is the most common primary small bowel malignancy, with the most common site being the duodenum. On the other hand, squamous cell carcinoma (SCC) of the duodenum is extremely uncommon. We report the first case of mixed adenocarcinoma and SCC occurring in the third part of duodenum (D3). Our patient, a 64-year-old female with history of GERD, hypertension, and IDDM presented with 4 weeks of nausea, vomiting, and abdominal pain...

Colorectal adenomas can show focal squamous differentiation or squamoid morules. We describe histologic findings of squamoid morules in the pseudoinvasive foci of colorectal polyps mimicking invasive carcinoma. Five colonic polyps with squamoid morules in the pseudoinvasive foci were collected. Histologic review and immunostains for cytokeratin (CK) 5/6, p63, synaptophysin, and chromogranin were performed on cases with squamoid morules. Forty-seven consecutive colorectal polyps with pseudoinvasion, none of which showed squamoid morules by histology review, and their clinicopathologic features were compared with the cases containing squamoid morules...

OBJECTIVE: Approximately 10% of non-small-cell lung cancer (NSCLC) remains unclassifiable as NSCLC-not otherwise specified (NOS), after using a panel of immunomarkers. The present study was undertaken to assess sensitivity and specificity of immunomarkers in sub-typing NSCLC on fine needle aspiration cytology (FNAC). Epidermal growth factor receptor (EGFR) mutations were also detected in these samples. METHODS: Sixty cases of NSCLC including 15 squamous cell carcinoma (SCC), 15 adenocarcinomas (ADC) and 30 NSCLC-NOS reported on FNAC were included in the study...

There have been occasional reports of primary cervical adenocarcinoma with areas of dedifferentiation resulting in morphologic mimicry of breast lobular carcinoma. We describe 4 cases of primary cervical squamous carcinoma with prominent acantholysis (3 cases), areas resembling breast lobular carcinoma (3 cases) or both (2 cases). All 4 tumors showed positivity with p63 and CK5/6 and 3 of 4 exhibited block-type immunoreactivity with p16. Two of the 4 cases contained high-risk human papillomavirus (types 16 and 18) on molecular testing; of the 2 cases which were human papillomavirus negative, 1 exhibited patchy nonblock immunoreactivity with p16...

Carcinosarcoma of the anus is rare and has yet to be reportedly associated with the keratinocyte-specific Human Papilloma Virus (HPV). We describe a case of anal carcinosarcoma with HPV infection in both the epithelial and mesenchymal components of the tumor by immunohistochemistry, chromogenic in-situ hybridization (CISH) and further supported by electron microscopy (EM). Microscopic examination of the tumor showed nests of poorly-differentiated invasive squamous cell carcinoma with basaloid features intermixed with a hypercellular, atypical spindle cell proliferation...

AIMS: The association between lung cancer and idiopathic pulmonary fibrosis (IPF) is well known, but the significance of this association is poorly understood. Bronchiolar honeycomb cysts have been proposed as possible precursors for the development of carcinoma, but limited evidence in support of this hypothesis is available. The aim of this study was to investigate this hypothesis analysing a series of carcinomas arising in IPF by immunohistochemistry. METHODS AND RESULTS: Thirty-three lung carcinomas arising in patients with IPF were analysed with a panel of immunohistochemical markers...

A 79-year-old Japanese woman presented with an ulcerated, brown-red nodule in the center of a sharply demarcated, tan-brown plaque situated on the left side of her right breast. Histologically, the plaque demonstrated an acanthosis with an intraepidermal epithelioma of Borst-Jadassohn. Small oval nests of bland-appearing basophilic cells in the periphery gradually enlarged into nests of various sizes and irregular shapes, composed of densely cohesive, atypical basophilic cells above the central nodule. The atypical keratinocytes shifted to atypical spindle cells beneath the acanthotic epidermis, penetrating deep into the subcutaneous tissue...

REVIEW
Shin-Ichi Ansai
This article reviews several topics regarding sweat gland and sebaceous neoplasms. First, the clinicopathological characteristics of poroid neoplasms are summarized. It was recently reported that one-fourth of poroid neoplasms are composite tumors and one-fourth are apocrine type lesions. Recent progress in the immunohistochemical diagnosis of sweat gland neoplasms is also reviewed. CD117 can help to distinguish sweat gland or sebaceous tumors from other non-Merkel cell epithelial tumors of the skin. For immunohistochemical differential diagnosis between sweat gland carcinoma (SGC) other than primary cutanesous apocrine carcinoma and skin metastasis of breast carcinoma (SMBC), a panel of antibodies may be useful, including p63 (SGC(+) , SMBC(-) ), CK5/6 (SGC(+) , SMBC(-) ), podoplanin (SGC(+) , SMBC(-) ) and mammaglobin (SGC(-) , SMBC(+) )...

BACKGROUND: Circulating tumor cells (CTCs) and microemboli (CTM) are attracting increasing attention in medical biology and clinical practice. However, the clinical relevance of CTCs in nasopharyngeal carcinoma (NPC) has not yet been ascertained, and no study has focused on the influence of Epstein-Barr virus (EBV) status on CTCs in NPC patients. These issues were therefore examined. METHODS: Peripheral blood samples were prospectively obtained from 33 NPC patients before treatment...
