Eyelid dermoid cyst: Case report of a rare manifestation

Abstract

Dermoid cysts are epidermis-like cysts with dermal adnexal structures such as sebaceous glands, hair follicles, or sweat glands in the cyst wall. They contain mature or immature germ cells of pluripotent origin. The usual sites of occurrence in the periorbital region include the lateral angle of the orbit, medial angle, limbal, and deep orbital region. Here, we present a case of 16-year-old female who came to the hospital with complaints of swelling in the upper eyelid and intermittent pain. After an excisional biopsy of the mass was done, the diagnosis of tarsal dermoid cyst was confirmed. Due to the paucity of cases in literature, reporting this case may help shed light on the importance of including dermoid cyst in the differential diagnosis of a tarsus-based eyelid mass.
