A Case of Chromophobe Renal Cell Carcinoma Coincident with Malignant Gastointestinal Stromal Tumor

Sarcomatoid Transrormation of Chromophobe Renal Cell Carcinoma

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...

Chromophobe renal cell carcinoma with osseous metaplasia: a case report.

A 60-year-old Japanese male with a chromophobe cell carcinoma of his left kidney is reported. The tumor, 18 x 27 mm in size, was incidentally found by abdominal ultrasonography. Computed tomography and magnetic resonance imaging demonstrated a well-demarcated solid tumor arising from the lower pole of the left kidney. Histopathological examination of the surgically removed tumor revealed that i...

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,...

Chromophobe Renal Cell Carcinoma with Sarcomatoid Differentiation

We report chromophobe renal cell carcinoma (CRCC) with sarcomatoid dedifferentiation in a sixty-five year old male. CRCC is a prognostically better, distinctive subtype of renal cell carcinoma (RCC), histologically characterized by cells containing translucent and reticulated cytoplasm with distinct cell borders. Sarcomatoid component accompanies 9% of CRCC which alters its prognostic implicati...
