Abstract

Urothelial papilloma (UP) of the bladder is an extremely rare benign neoplasm in pediatrics, often manifested as gross hematuria. These lesions are typically small, well-circumscribed, located on the lateral or posterior bladder wall, frequently near the ureteral orifice. These small masses typically have a good prognosis with a favorable outcome.

Keywords: children; hematuria; urinary bladder; urothelial papilloma.
