Rectal Prolapse due to Adenomatous Polyp: Case Report

Abstract

Rectal prolapse represents full thickness protrusion of the rectum through the anal sphincter. Rarely, the prolapsed portion of the rectum can become neoplastic. The exact incidence of rectal prolapse although unknown, it is a rather rare entity. We hereby report a case of a rectal prolapse with neoplastic change. The present study report the case of a 58-year-old woman, without previous major diseases, diagnosed with a rectal prolapse. Eight months later she attended with evident prolapse towards the posterior quadrant of the anal margin with a polypoid lesion of approximately 5 cm × 5 cm. An altemeier's rectosigmoidectomy is executed. The histopathologic study reports a tubulovillous adenoma with high grade dysplasia.
