Sarcomatoid renal cell carcinoma with rhabdoid features

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...

Sarcomatoid Transrormation of Chromophobe Renal Cell Carcinoma

Renal Cell Carcinoma With Rhabdoid and Sarcomatoid Features Presented as a Metastatic Thigh Mass With an Unusual Immunohistochemical Profile

Renal cell carcinoma (RCC) may metastasize anywhere in the body and sometimes the primary tumor is missing and necessitates extensive investigations to detect. In this report, we describe a case of RCC metastasizing to the thigh in a 70 year old male with a highly pleomorphic morphology suggesting a high grade sarcoma that showed unequivocal positivity for desmin directing the diagnosis for ple...

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...
