Urothelial papilloma: a rare cause of gross haematuria in childhood

Urothelial Papilloma of the Urinary Bladder: A Case Report and Literature Review of a Rare Entity

Urothelial papilloma is a rare benign neoplasm composed of a delicate fibrovascular core covered by normal urothelium. In this report, we present a case of an incidentally detected endovesical papillary growth in ultrasound scan (USS) during a routine check-up, suggestive of bladder tumor which was also suggested by CT urography. The tumor was initially managed with transurethral resection and immediate intravesical instillation of mitomycine C 40 mg. The histopathologic assessment of the specimen concluded that the growth was “urothelial papilloma with no atypia or malignancy.” Although papilloma is unequivocally benign, it can recur; recurrences can be multiple and can occur years after the initial diagnosis occasionally with progression to carcinoma, hence long-term surveillance is essential. Our case was followed up for a year with no signs of recurrence or progression and long-term surveillance will be done annually.
