Atypical manifestation of giant epidermal cyst over sacrum coccygeal region in elderly male

Abstract

Epidermal cysts are benign tumors commonly known as sebaceous cyst and frequently found throughout the body. These are lined with true, stratified-Squamous epithelium, derived from hair follicle. They can grow of any size and maybe get infected frequently over a period of time. Epidermal is usually asymptomatic and mostly presents as a slowly growing painless mass. Epidermal cyst is most commonly confused with other cysts like dermoid cyst but histopathological examination provides the final diagnosis. We are reporting here an unusual presentation of large epidermal cyst in an old person over sacrum-coccygeal region which was successfully surgically excised. An epidermal cyst of this size is rarely reported over this region.
