Mucoepidermoid Carcinoma Ex Pleomorphic Adenoma of Lacrimal Gland: Case Report and Review of Literature.

Carcinoma ex pleomorphic adenoma (Ca ex PA) is defined as an infiltrative carcinoma arising from a primary or recurrent benign pleomorphic adenoma. Ca ex PA with the histologic subtype mucoepidermoid carcinoma is extremely uncommon. Only 2 previous reports in the lacrimal gland have been documented. We reported a 55-year-old lady with a firm, solid, nontender mass in the supralateral quadrant of the right orbit at the area of the lacrimal gland. After wide excision of mass, pathology revealed high-grade mucoepidermoid carcinoma Ex pleomorphic adenoma. To reduce tumor recurrence 60 Gray radiation was delivered to the orbital cavity. She is still tumor-free 1 year after completion of treatment.
