[Bladder tumors in patients under 40 years of age].

A total of 13 patients under the age of 40 years were treated for bladder carcinoma. One child had a bladder sarcoma. 8 patients had a superficial transitional cell carcinoma with no evidence of recurrence after endoscopic resection. Four patients had invasive bladder carcinoma. Superficial bladder carcinoma would appear to have a good prognosis in patients under 40 years of age.
