Bladder urothelial papilloma is extremely rare in the paediatric population. It usually presents as painless gross haematuria and its diagnosis implies a high index of suspicion as other causes of haematuria predominate in this age range. We describe a 9-year-old boy with two episodes of gross haematuria occurring 1 year apart with spontaneous resolution after 2 days. Bladder ultrasound revealed an endovesical papillary lesion of 24×24 mm suggestive of bladder tumour. The diagnosis was confirmed by histopathological examination of the specimen obtained by cystoscopy with transurethral resection. After 3 years of follow-up with ultrasound and cystoscopy, there are no signs of recurrence. Due to the low prevalence of urothelial papilloma, paediatric guidelines for appropriate management and follow-up are unavailable, making this a challenging entity.
