Orbital epidermoid cysts are a rare cause of an orbital mass.
Patients most commonly present with a mass and lid swelling 1.
Orbital epidermoid cysts can be congenital, acquired (e.g. post-surgery, trauma), or lacrimal gland duct obstruction 3. They can be associated with a bone defect and when involving the skull base intracranial extension is possible 1.
Most commonly, they affect the eyelid (i.e. periorbital) but can also occur in the orbit proper 3.
