title: Inverted transitional cell carcinoma of the ureter.
abstract: An inverted urothelial tumor (transitional cell carcinoma, inverted type, grade 1), consisting of a large (3.5 x 1.2 x 1.2 cm) tumor with stalk (0.3 cm in diameter) and surrounding broad base polypoid foci (0.5 x 0.6 x 0.5 cm altogether), was found in the lower segment of the left ureter of a 59-year-old man. He has taken oral anticancer drugs and kanpo medicine as a follow-up for 61 months, and is now free of disease. Differential diagnosis, inverted urothelial papilloma and carcinoma, and adequate treatment are discussed.
