Abstract

An epidermal cyst is the most common cutaneous cyst, and is the result of the proliferation of surface epidermal cells within the dermis. It is unusual that these cysts occur in mucosa, including an oral or perioral location. We report a patient with a labial epidermal cyst, which probably originated from adjacent hair follicles. We excised the tumor using an intraoral approach for better cosmetic result. This case is interesting, due to findings of a labial epidermal cyst resembling a mucocele or salivary gland tumor in morphology, and a connection finding of a cystic base with adjacent hairy skin, suggesting a subcutaneous infiltration of the cyst.
