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\u2009year apart with spontaneous resolution after 2 days. Bladder ultrasound revealed an endovesical papillary lesion of 24\u00d724\u2009mm suggestive of bladder tumour. The diagnosis was confirmed by histopathological examination of the specimen obtained by cystoscopy with transurethral resection. After 3\u2009years 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.<\/jats:p>","DOI":"10.1136\/bcr-2017-219341","type":"journal-article","created":{"date-parts":[[2017,5,13]],"date-time":"2017-05-13T07:25:21Z","timestamp":1494660321000},"page":"bcr-2017-219341","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Urothelial papilloma: a rare cause of gross haematuria in childhood"],"prefix":"10.1136","volume":"2017","author":[{"given":"Andreia","family":"Ribeiro","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria","family":"Pereira","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Armando","family":"Reis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gra\u00e7a","family":"Ferreira","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2017,5,13]]},"reference":[{"key":"2025042706102828000_2017.may12_5.bcr-2017-219341.1","doi-asserted-by":"crossref","first-page":"1519","DOI":"10.1016\/S0031-3955(05)70389-8","article-title":"Hematuria in children","volume":"48","author":"Patel","year":"2001","journal-title":"Pediatr Clin North Am"},{"key":"2025042706102828000_2017.may12_5.bcr-2017-219341.2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpurol.2014.08.008"},{"key":"2025042706102828000_2017.may12_5.bcr-2017-219341.3","doi-asserted-by":"crossref","first-page":"175","DOI":"10.1016\/j.urology.2015.12.032","article-title":"Transitional cell carcinoma in the Pediatric patient: a review of the Literature","volume":"91","author":"Chu","year":"2016","journal-title":"Urology"},{"key":"2025042706102828000_2017.may12_5.bcr-2017-219341.4","doi-asserted-by":"crossref","first-page":"771","DOI":"10.1007\/s11255-015-0950-z","article-title":"Urothelial carcinoma of the urinary bladder in pediatric patients: a long-term follow-up","volume":"47","author":"Ander","year":"2015","journal-title":"Int Urol Nephrol"},{"key":"2025042706102828000_2017.may12_5.bcr-2017-219341.5","doi-asserted-by":"crossref","first-page":"106","DOI":"10.1016\/j.eururo.2016.02.028","article-title":"The 2016 WHO classification of Tumours of the Urinary System and Male Genital Organs-Part B: prostate and bladder tumours","volume":"70","author":"Humphrey","year":"2016","journal-title":"Eur Urol"},{"key":"2025042706102828000_2017.may12_5.bcr-2017-219341.6","doi-asserted-by":"crossref","unstructured":"Moch H , Humphrey PA , Ulbright TM , et al .
