Fourteen years after en bloc resection of an orbital pleomorphic adenoma, a 61-year-old female patient developed progressive left proptosis on the same side. A CT scan revealed a round, well-circumscribed, heterogeneously enhancing mass in the lacrimal fossa of the left orbit without calcification or bone erosion. An MRI scan showed a lesion that was hypointense on T1-weighted images and heterogeneously isointense on T2-weighted images. The tumor was completely resected through combined anterior and lateral orbitotomy. On histopathology, the specimen was identified as epithelial-myoepithelial carcinoma. After surgery, the patient received adjuvant therapy with irradiation of the orbit. At a 36-month follow-up evaluation, the patient remained tumor-free. Epithelial-myoepithelial carcinoma, a very uncommon tumor of the orbit, apparently behaves like a low-grade malignancy and is associated with good survival rates. However, a good prognosis for survival is tentative at best, in part because of the rarity of the lesion.
