Abstract

Epidermoid cysts are rare, slow-growing, benign, developmental cysts that are derived from abnormally situated ectodermal tissue. Epidermoid cysts may grow anywhere on the body and about 7% of them are located in the head and neck. These cyst arise from traumatic implantation of epithelium or entrapment of epithelial remnants during embryonic fusion. Histopathologically, they are lined by stratified squamous epithelium and ,lumen without any skin appendages. Here we present a case of epidermod cyst occurring in sub-mandibular region.

Keywords: Dermoid cyst; epidermoid cyst; skin appendages.
