Incidentally discovered urothelial papilloma in a 9-year-old girl.

Urothelial papilloma is a rare benign bladder tumor in children, usually presenting with hematuria. We report a 9-year-old girl with incidentally discovered bladder urothelial papilloma during evaluation of abdominal pain, without urinary symptoms. Ultrasound revealed a small papillary bladder lesion, which was completely resected via transurethral resection. Histopathology confirmed urothelial papilloma. This case highlights the importance of considering bladder pathology even in asymptomatic pediatric patients. Complete resection is curative, but careful follow-up is recommended due to probability of recurrence, although uncommon.
