title: Urothelial carcinoma occurring within an inverted papilloma of the ureter.
abstract: Only 5 cases of inverted papilloma of the ureter with a malignant component have been reported previously. We add case 6 to the literature. The incidence of concomitant malignancy in ureteral inverted papillomas is 3 times that found in similar lesions occurring in the bladder.
