Simultaneous diagnosis of ipsilateral adenoid cystic carcinoma of the lacrimal gland and orbital cavernous hemangioma: case report.

To describe a patient with coexistence of ipsilateral adenoid cystic carcinoma of the lacrimal gland and orbital cavernous hemangioma. The patient presented a 2-month history of painful swelling of left upper eyelid, which did not resolve on a course of oral steroid. On clinical examination, she had moderate medial and inferior dislocation of the eye globe, edema of the temporal superior eyelid and moderate restriction upgaze. Magnetic resonance imaging identified two left orbital tumors: one was a lesion that arose from the lacrimal gland, and the second was a well-defined, ovoid, intraconal mass. The patient underwent lateral orbitotomy and excision of both lesions. Postoperative histological features demonstrated two different lesions: an adenoid cystic carcinoma of the lacrimal gland and a cavernous hemangioma. The clinical presentation of the present case was strongly suggestive of a lacrimal gland malignancy, although the imaging features did not show typical invasive aspects. This is the first report of coexistence of lacrimal gland adenoid cystic carcinoma and cavernous hemangioma in the ipsilateral orbit.
