[Vesical urothelial papilloma].

INTRODUCTION: Vesical tumors of infancy are of a low incidence and isolated clinical cases exist, and therefore there are no protocols regarding treatment and monitoring. In addition, the histological criteria used until now are the ones in the WHO 2004 guidelines.

CLINICAL CASE: A 11 year old boy with non-specific abdominal pain. Upon abdominal ultrasound a tumor is observed near the left ureteral orifice, and proceeding with Thulium laser vaporization, a histological diagnosis is made: vesical urothelial papilloma.

COMMENTS: Different diagnostic and therapeutic methods are discussed, with particular emphasis on the importance of a correct diagnosis due to risk of confusion with carcinomas. Despite benign, there is a risk of malignant progression and we recommend pursuing clinical follow-ups and periodical ultrasounds, performing cystoscopy in case of suspicious findings on ultrasound.
