title: Orbital dermoid cyst with sinus tract mimicking ectopic cilia.
abstract: Dermoid cysts are the most common periorbital masses presenting in childhood. We describe an unusual case of a dermoid cyst presenting with black hairs emerging from a sinus tract on the upper eyelid and mimicking the appearance of ectopic cilia. Our case highlights the value of radiologic examinations in such cases.
