Purpose/methods: A 49-year-old woman with a left orbital mass was referred to an orbital clinic. Clinical investigation suggested a lacrimal gland lesion and the patient underwent lateral orbitotomy and excisional biopsy for a suspected pleomorphic adenoma in the lacrimal gland.
Results/conclusion: Histopathologic evaluation disclosed a hemangiopericytoma originating within the lacrimal gland. Although hemangiopericytoma does not usually occur in this location, it may be added to the differential diagnosis of lacrimal gland enlargement.
