Chromophobe Renal Cell Carcinoma, Oncocytoma and Clear Cell Carcinoma: A Compartive Immunohistochemical Study

Sarcomatoid Transrormation of Chromophobe Renal Cell Carcinoma

S100 Expression in Oncocytoma and Chromophobe Renal Cell Carcinoma: An Immunohistochemical Study

Oncocytoma and chromophobe renal cell carcinoma may show a certain degree of histological overlap. The problem of differentiating both types is expected to increase because of the more frequent use of needle biopsies to diagnose small renal masses. In this study. The expression and the possible diagnostic utility of S 100 was evaluated in both oncocytoma and chromophobe renal cell carcinoma, us...

Immunohistochemical analysis of chromophobe renal cell carcinoma, renal oncocytoma, and clear cell carcinoma: an optimal and practical panel for differential diagnosis.

CONTEXT The separation of chromophobe renal cell carcinoma, oncocytoma, and clear cell renal cell carcinoma using light microscopy remains problematic in some cases. OBJECTIVE To determine a practical immunohistochemical panel for the differential diagnosis of chromophobe carcinoma. DESIGN Vimentin, glutathione S-transferase alpha (GST-alpha), CD10, CD117, cytokeratin (CK) 7, and epithelial...

Sarcomatoid Chromophobe Renal Cell Carcinoma with Heterologous Component

Clear cellrenal cell carcinoma (RCC) is the most common malignant renal tumor in adults, while chromophobe RCC (CRCC) is the third most common. Any subtypes of RCC can undergo sarcomatoid differentiation, but heterologous differentiation in sarcomatoid area is very rare in RCC. Here a61-year male is presented with hematuria and palpable mass. Clinicoradiologically, RCC was considered and left r...

Metastatic Renal cell Carcinoma Presenting as a clear-cell Tumor in Tongue: A Case Report

Introduction: Metastatic lesions of the oral cavity are extremely rare, accounting for approximately 1% of all malignant oral tumors. The most common primary sources of metastatic tumors in the oral region are, from the most to the least common, the breast, lung, kidney, bone, and colon. Renal cell carcinoma accounts for nearly 3% of all adult malignancies. It usually metastasizes to the lungs,...
