Abstract
Introduction
We report the clinical features and the management of two cases of orbital hidrocystoma in the setting of an enlarging orbital mass.
Cases description
A 48-year-old man presented with a mass in the right upper medial orbital quadrant, firmly attached to the supraorbital incisure. A 70-year-old man had a well demarcated lesion in the upper lateral orbital quadrant adherent to the lacrimal gland. There was no history of previous orbital trauma. In both cases histopathology confirmed a diagnosis of apocrine hidrocystoma. Following surgery, the first patient complained of mild hypoesthesia in the territory of the supraorbital nerve that resolved spontaneously within 3 weeks. Surgery was uneventful in the other patient. No recurrence was seen during the follow up.
Conclusions
Apocrine hidrocystomas have been rarely described in the orbit, but should be considered in the differential diagnosis of orbital cystic masses. Recurrence is rare following complete surgical excision.
