Pleomorphic Adenoma With Prominent Clear Cell Myoepithelioma Component of the Lacrimal Gland

Ophthalmic Plast Reconstr Surg. 2016 Jan-Feb;32(1):e18-21. doi: 10.1097/IOP.0000000000000374.

Abstract

A case of a pleomorphic adenoma of the lacrimal gland with a prominent clear cell myoepitheliomatous component was reported. An 81-year-old Caucasian woman experienced a 2-month history of right supraorbital swelling and proptosis. Excisional biopsy revealed a multicomponent lesion including a stromal component featuring glandular structures made of small epithelioid and spindle cells and a trabecular component with small islands of vacuolated cells, displaced nuclei, and clear cytoplasm. Immunohistochemical analysis revealed strong cytokeratin AE1/3 reactivity and focal smooth muscle actin positivity. The pathologic findings including immunohistochemistry results were consistent with a pleomorphic adenoma with prominent clear cell myoepithelioma component.
