ABSTRACT
Sarcomatoid renal cell carcinoma (SRCC) is an uncommon, aggressive renal cell carcinoma (RCC) accounting for 1.2% to 12.3% of renal cell carcinomas. SRCC may arise from any RCC subtype as it probably results from the de-differentiation of any renal epithelial malignancy. SRCC is characterised by a rapid progression and high metastatic rate. Currently there is no specific effective treatment for it. We report a new case of a 32-year-old man presented with two months backache. Ultrasound revealed a 7.5 cm heterogeneous mass at the inferior pole of the left kidney. A nephrectomy was performed. Histological study diagnosed a sarcomatoid renal cell carcinoma. The patient was doing well 6 months after initial surgery and then was lost to follow-up.
