Posttraumatic benign pleomorphic adenoma of the lacrimal gland

A 55-year-old man presented with a painless and slowly developing mass in the right superior lateral eyelid region. He had sustained periorbital blunt injury about 4 years previously. The mass was observed several months later in the persisting traumatic tumefaction region. Computed tomography showed a cystic soft-tissue mass with central low density and peripheral enhancement over the upper anterior quadrant of the right orbit. Lateral orbitotomy was performed to remove the lesion. Histopathologic examination showed proliferation of epithelial and myoepithelial cells arranged in ductules and nests in the myxoid stroma. Benign pleomorphic adenoma of the lacrimal gland associated with traumatic tumefaction, as demonstrated in our patient, may be rare.
