Sarcomatoid carcinoma of the urinary bladder: 3 case reports.

Three cases of sarcomatoid carcinoma of the urinary bladder are considered. The patients were 2 males, aged 68 and 81 years, and a 79-year-old female. Transurethral resection of the bladder tumor (TUR-BT) and consecutive radical cystectomy were performed in all patients. Local progression of bladder tumors just after TUR-BT was recognized in the 2 younger patients, each of whom died due to recurrence after radical cystectomy. Because of the extremely aggressive malignant potential of sarcomatoid carcinomas, the indications for TUR-BT should be carefully assessed and suitable therapeutic strategies should be examined further.
