Papilloma of the urinary bladder

This is a survey of 125 patients with bladder papilloma with particular attention to the later development of unequivocal bladder carcinoma. The following conclusions were reached: conservative management for benign papilloma is justified, but close follow-up is essential; cancer of sites other than bladder and ureter occurs with increased frequency after or concomitant with bladder papilloma; and the development of bladder carcinoma in the patient with prior bladder papilloma is a definite risk and warrants aggressive treatment.
