Thedieck and colleagues revealed loss of Ksp-cadherin in CCRCC. Ksp-cadherin was subsequently proposed to differentiate chromophobe RCC from oncocytoma. However, additional studies failed to reveal any... [Pg.633]

Glutathione-transferase alpha (GST-a) protects cells by catalyzing the detoxification of xenobiotics and carcinogens. GST-a was recently found to be of diagnostic value in renal tumors. On the basis of cDNA microarray findings, immunohistochemical studies have so far shown GST-a to be highly expressed in CCRCC (90%) but not in ChRCC or oncocytomas and only occasionally in PRCC. [Pg.635]

Oncocytomas are benign renal neoplasms characterized by a typical gross mahogany-brown color. Microscopically, the tumor is composed of islands of oncocytic cells with coarsely granular eosinophilic cytoplasm set in a typical edematous myxoid focally hyalinized Oncocytomas display round, vesicular. [Pg.635]

Immunohistochemically, oncocytomas are positive for pancytokeratin AE1/AE3 and low-molecular cyto-keratin CAM5.2 and are negative for vimentin. Q-kit (GDI 17) expression is encountered in more than two thirds of oncocytomas, a feature also shared by chromophobe Similarly, Ksp-cadherin is... [Pg.635]

Commonly encountered cytogenetic findings in oncocytomas include loss of chromosome Y and chromosome 1.385-391... [Pg.636]

Oncocytoma-like angiomyolipomas have distinct granular eosinophilic cytoplasm, bringing the diagnosis of renal oncocytoma into the differential diagnosis. [Pg.640]
