Abstract
A 36 yr old man with carcinosarcoma of the bladder is described. The literature is reviewed, and the clinicopathology is discussed. These tumors tend to be bulky, rapidly growing, invasive and recur locally. Metastases are generally hematogenous and may rarely involve regional nodes. Deaths are commonly due to local invasion and sepsis. Preoperative overstaging may occur, and pelvic arteriography and exploration are recommended in questionable cases. Because of the difficulty in locally extirpating these tumors, radical cystectomy and urinary diversion are recommended.
