Lymphoepithelial - like carcinoma, is rarely recognized in the urinary bladder and less commonly occurs with papillary transitional cell carcinoma i.e. mixed pattern. Also, less uncommon is the occurrence of carcinoma in situ changes in the adjacent urothelium of these tumors. Here, a case of lymphoepithelial – like carcinoma and papillary transitional cell carcinoma associated with carci...

The most usual form of the endocrine carcinoma is thyroid cancer (TC). In addition to papillary thyroid carcinoma (PTC), recent studies revealed incidence of RET/PTC rearrangement in other tumors, like Hürthle cell carcinoma (HCC) and even in non-carcinomatous disorders like Hashimoto's thyroiditis. Here, we present a case with concurrence of papillary thyroid carcinoma and Hürthle cell carcino...

the sex cord-like variant of endometrioid carcinoma is a rare subtype with a close histological resemblance to the sex cord-stromal tumor of the ovaries, in particular the sertoli cell tumor. however, very few cases of the granulosa cell tumor-like variant have been reported since it is commonly misdiagnosed as a granulose cell tumor. immunohistochemistry is useful in the diagnosis of these tum...

This review deals with studies that have used cDNA microarrays and immunohistochemistry to identify a subtype of breast carcinoma recently known as “basal-like” carcinoma. The key breast carcinoma studies are critically discussed to highlight methodological problems in cohort selection, definitions, interpretation of results, an...

this review deals with studies that have used cdna microarrays and immunohistochemistry to identify a subtype of breast carcinoma recently known as “basal-like” carcinoma. the key breast carcinoma studies are critically discussed to highlight methodological problems in cohort selection, definitions, interpretation of results, and statistical analysis. it concludes that “basal-like” carcinomas d...

introduction : fibrolamellar carcinoma (flc), a subtype of hepatocellular carcinoma (hcc), is a rare primary hepatic malignancy. several aspects of the clinical features and epidemiology of flc remain unclear since most literature on flc consists of case reports and small cases series with limited information on factors that affect survival. majority of the tumors occurred in patients less than...

the coexistence of two malignancies is rarely seen. a little association between hematologic malignancies especially multiple myeloma and renal cell carcinoma has been reported in the recent past. several case series revealed a bidirectional association between these two malignancies which may be due to the common risk factors, similar cytokine growth requirements and clinical presentation. her...
