Inverted papilloma is a rare, endophytic, benign neoplasm which frequently develop at the trigone of the bladder. However, because of histologic feature, growth pattern developed location, it has been argued about histogenesis of inverted papilloma of the bladder. In our case, it is histologically observed that inverted papilloms is originated from proliferative cystitis, that is, cystitis cystica and glandularis. A case of inverted papilloma of the urinary bladder in 58 years old female is presented with review of the literature.
