title: Tubulovillous Adenoma in a Urethral Neobladder Anastomosis.
abstract: We present a case of a tubulovillous adenoma arising in a neobladder that was managed by cystoscopic resection. A 64 year-old male underwent a cystectomy with creation of an ileocolic neobladder urinary diversion for T2 urothelial carcinoma of the bladder. Nine years following his surgery, the patient noted several episodes of gross hematuria. Cystoscopic evaluation revealed the rare occurrence of a 3 cm tubulovillous adenoma with high-grade dysplasia at the neck of the neobladder.
