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 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...

Chromophobe renal cell carcinoma with sarcomatoid changes: case report and review of literature

Chromophobe renal cell carcinoma (RCC), a subtype of RCC, accounts for 4-6% of all RCC and has better prognosis then conventional RCC. Sarcomatoid dedifferentiation is thought to represent the high-grade end of all subtypes. This makes chromophobe RCC with sarcomatoid changes a rare entity associated with poor prognosis in most studies. We present a case of a 40-year old female with this rare h...

Lymphangitic Retroperitoneal Carcinomatosis Occurring From Metastatic Sarcomatoid Chromophobe Renal Cell Carcinoma

Forty -five year-old man with left renal mass underwent nephrectomy to reveal 20cm tumor diagnosed as sarcomatoid chromophobe renal cell carcinoma (CRCC). Lymph node metastasis of chromophobe and sarcomatoid components, disseminated tumor in retroperitoneal fat, lymphatic vessels, peri-renal adipose tissue in lymphangitic carcinomatosis pattern were identified. Chromophobe epithelial cells EMA,...
