Abstract

Inverted papilloma of the urinary tract is a unique and rare tumor. It is generally considered a benign lesion, although previous reports have alluded to the possibility of malignant change. The lesion is believed to arise mainly from trigon and bladder outlet as a result of chronic. proliferative cystitis. The most commonly associated clinical symptoms are hematuria and those of urinary obstruction. We report two cases of vesical inverted papilloma which were proved histologically.
