Sarcomatoid Renal Cell Carcinoma: A Rare Case Report.

Sarcomatoid renal cell carcinoma (SRCC) is an aggressive variant of renal cell carcinoma. It is thought to originate predominantly from clear cell carcinoma through de-differentiation. It is a rare entity constituting about 1-5% of all renal malignant neoplasms and is more commonly associated with conventional (clear cell) renal cell carcinomas. We report a case of 62 years old male who presented with complaints of haematuria and abdominal pain. The histopathology confirmed sarcomatoid renal cell carcinoma. [ABSTRACT FROM AUTHOR]
