Urothelial papilloma is a rare, benign, polypoid bladder tumor covered by urothelium indistinguishable from normal urothelium. It presents in patients between 23 and 87 years of age, mainly those under 50 years of age with no history of malignancy, with a male to female ratio of 2:1. The clinical spectrum of presentation ranges from painless hematuria to asymptomatic patients, demonstrating its presence as an incidental finding. Understanding the biological character and establishing the correct differential diagnosis between the various papillary tumors is of priority importance for the treatment and prognosis of patients.
