Carcinosarcoma of Kidney

Abstract

A case of carcinosarcoma of kidney in a fiftyone year old Korean male is presented concerning with its rarity and unusual morphologic findings. Rhabdomyosarcomatous and chondrosarcomatous components comprised the bulk of tumor mass in which were proportionally abundant clear cell variety of renal cell carcinoma intermixed. It is of authors' opinion that carcinosarcoma of kidney is very similar to adult type nephroblastoma but appears histologically different from the latter by the presence of clear cell variety predominating the carcinomatous element and by no evidence of transformation between two components.
