Intraorbital epidermoid cyst: a 5-year-old with exophthalmos and strabismus.

A 5-year-old girl with right exophthalmos and esotropia presented to ophthalmology outpatient clinics. Orbital computed tomography revealed a 20- to 30-mm oval soft tissue mass lying superolateral to the right lateral rectus muscle in the orbit. The patient was operated on by a neurosurgical team, the csyt was removed totally, and examination of the pathologic specimen, which reveals the epidermoid cyst, was performed. After the operation, exophthalmos and esotropia were improved, and visual acuity was increased. Although itis seen as a rare entity in the orbit, epidermoid cyst must be considered during the investigation of exophthalmos.
