title: A case of villous adenoma of the urinary bladder with tubulovillous architecture: characterization by immunohistochemical analysis.
abstract: Villous adenomas of the urinary tract are rare as compared to urothelial carcinoma. We report a case of urinary bladder villous adenoma in a 90-year-old woman. Cystoscopic examination revealed a papillary tumour in the diverticulum at the posterior wall of the urinary bladder. Transurethral resection was performed and histopathological examination revealed predominantly tubulovillous architecture, and showed an identical immunohistochemical profile to villous adenoma associated with cystitis glandularis.
