Retrorectal Mucinous Adenocarcinoma Arising from a Tailgut Cyst: A Case Report

Abstract

We report the case of a 57-year-old woman who presented with local invasion of the anal canal by mucinous adenocarcinoma, the malignant transformation of a long-term preexisting retrorectal tailgut cyst. This progression is infrequent and justifies preemptive surgical treatment of retrorectal cysts.
