Tailgut Cyst Prolapsing through the Anus

Introduction

The tailgut cyst is a rare congenital malformation. It is a remnant of the postanal part of the hindgut, which normally regresses totally during the embryonic period. Most cases are asymptomatic and are diagnosed by incident as a presacral mass, other cases may present with different and unspecific symptoms.[1] [2] [3] [4] [5] This case presenting as a prolapse through the anus has, to our knowledge, not been reported previously.
