Atypical intraorbital dermoid and epidermoid cyst: A single institution cross-sectional retrospective study

Abstract

Purpose: Intraorbital epidermoid and dermoid cyst (DC) has been reported in the literature rarely. The current study evaluates clinicopathologic, radiologic, and management of intraorbital DC cases over ten years.Methods: In this cross-sectional study, the medical records of patients with intraorbital DC treated at the academic referral center for ocular surgery were retrospectively reviewed. Data reviewed included the patient's de-mographic characteristics, clinical features, imaging, surgical technique, and pathology report.Results: Nine patients with a rare presentation of intraorbital DC were reviewed within the study period in five presentations (five intraosseous, one intraconal, one dumbbell-shaped with a large part in anterior orbit, one juxta levator palpebral muscle, and one recurrent case with intracranial extension). They ranged from 8 to 53 years of age, with a median of 29 years, and five (55.6) were female. Histopathological evaluation revealed two cysts were epidermoid. Conclusion: The current study provides more clinical and radiologic manifestations of rare presentations of DC that highlight the importance of high clinical suspicion in the approach to atypical DC.
