Papillary carcinoma is the most common type of thyroid malignancy. It has been recently shown that these tumors commonly have one of three genetic alterations: BRAF point mutations, RET/PTC rearrangements, or RAS point mutations. In this study, we analyze the relationship between these alterations and the microscopic features of papillary carcinomas, their(More)
BACKGROUND Pediatric renal cell carcinoma (RCC) is clinically distinct from adult RCC. Characterization of the unique biological and clinical features of pediatric RCC are required. METHODS A retrospective review and biological analysis of all RCC cases presenting to Cincinnati Children's Hospital Medical Center (CCHMC) in the last 30 years was(More)
Seventeen cases of granular cell tumor (GCT) of the breast are reviewed. The demographics and clinical features are reviewed and the radiologic and pathologic features as well as the immunohistochemistry are discussed. To our knowledge, our series of 17 breast GCT cases represent the largest series published to date.
Renal cell carcinomas associated with syndromes of a heritable nature account for about 4% of all renal cell carcinomas. They are characterized by an earlier age of onset, and are often multicentric and bilateral. Some of these patients may fit into well-characterized kidney cancer syndromes, while many more may have a genetic component that is not fully(More)
Merkel cell carcinoma (MCC) is a rare and highly aggressive primary neuroendocrine carcinoma of the skin with a high propensity for local, regional, and distant spread. Distant metastasis of MCC to the pancreas is uncommonly seen and may impose a diagnostic challenge cytologically. Here we report a case of MCC with pancreatic metastasis, which was diagnosed(More)
In this short review, we discuss clear cell adenocarcinoma of the urinary bladder, a rare tumor that primarily affects women. The histogenesis of this neoplasm is uncertain; in some tumors the clinicopathologic and histologic features are suggestive of a müllerian origin. Clear cell adenocarcinoma consists of cells with abundant clear cytoplasm, arranged in(More)
BACKGROUND The BRAF V600E mutation has been reported in 50%-80% of papillary thyroid carcinoma (PTC) cases and is highly specific for PTC. Reflex BRAF testing may improve the diagnostic accuracy of thyroid fine-needle aspiration (FNA) tests having equivocal cytologic interpretations and provide prognostic information that helps guide management in patients(More)
Pancreatic plasmacytoma is a rare disorder which may present with obstructive jaundice. Only eighteen cases have been reported in the English language literature. We present the first case of pancreatic plasmacytoma and gastric plasmacytoma diagnosed with endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). A 75-year-old male with a known history(More)
The role of fine needle aspiration (FNA) biopsy of renal cortical lesions was controversial in the past because the result of the FNA did not affect clinical management. All renal cortical lesions, except metastasis, were subject to surgical resection. However, with the advances in neoadjuvant targeted therapies, knowledge of the renal cortical tumor(More)
Follicular variant of papillary thyroid carcinoma (FVPTC) creates a continuous diagnostic dilemma among pathologists because of the paucity of nuclear changes of papillary carcinoma and overlapping features with benign and other neoplastic follicular lesions. Current guidelines for the management of thyroid nodules recommend surgery for confirmed PTC,(More)
