Abstract

Dermoid cysts in the orbit classically present in children as a mass in the superotemporal or superonasal orbit along the zygomatico-frontal or fronto-ethmoidal suture lines. The presence of a dermoid cyst in the superficial eyelid, not associated with the tarsus, has only been reported once previously. The authors present a case of a 60-year-old man with a painless right lower eyelid mass inferonasally that was completely excised and found to be a dermoid cyst. The presence of a dermoid cyst involving the superficial lower eyelid is very rare. Furthermore, dermoid cysts in adults typically present in the setting of trauma, which was absent in this case. Therefore, it is important to consider dermoid cysts in the differential diagnosis of eyelid lesions in adults.
