title: [Sarcomatoid renal carcinoma].
abstract: Sarcomatoid renal carcinoma is an uncommon but not rare histologic variant of renal carcinoma that accounts for 1-1.5% of all renal masses. It may originate from metaplasia of carcinomatous epithelial cells. Clinically, it generally presents as a large renal mass. The survival rate after diagnosis is approximately 6 months. We report on a 71-year-old male patient with general clinical features of paraneoplasia and a mass in the left kidney. Histological work up revealed a sarcomatoid renal carcinoma and the patient survived 4 months after the diagnosis was made.
