Abstract

Epidermoid inclusion cysts of the perineal region are a rare entity, which require appropriate diagnosis and management. Here we describe the unusual case of a large protruding epidermoid inclusion cyst originating from the intersphincteric anal plane, which was mobilized and excised successfully. Essential investigations to ensure accurate diagnosis in addition to surgical technique to reduce recurrence and patient morbidity are described in this case report.

INTRODUCTION

Epidermoid inclusion cysts are uncommon and benign developmental cysts, which progress over time due to incorporation of epidermal tissue into the dermis layer of the skin [1]. They are commonly found in the head and neck region and cause no symptoms at rest; however, these are susceptible to infection and inf lammation causing discomfort [1]. In this study, we describe a rare case of an epidermoid inclusion cyst arising between the two anal sphincters and recommend essential investigations and surgical technique to ensure accurate diagnosis and to reduce recurrence and patient morbidity.
