Giant Orbital Hydrocystoma in Children: Case Series and Review of the Literature

Objective: To describe the clinical features, ancillary diagnostic studies, and treatment outcomes in a cohort of pediatric patients with giant orbital hydrocystomas. Design: Retrospective case series. Participants: Pediatric patients with giant orbital hydrocystomas treated in the practice of one surgeon (PDL). Methods: A retrospective review of the clinical charts of pediatric patients with orbital hydrocystoma was performed and diagnostic information collected. Results were reviewed and compared with reported clinical data in the literature. Main Outcome Measures: Clinical presentation and histopathological findings of pediatric orbital hydrocystomas. Results: Three pediatric cases of giant orbital hydrocystoma were encountered, each with an unusual feature, including deep orbital location, occurrence following trauma, and eccrine pathology. Conclusion: Giant orbital hydrocystomas may present in the pediatric population. Ophthalmologists should be cognizant of this entity when evaluating a child with a large, cystic orbital mass.
