Epithelial-myoepithelial carcinoma of the parotid gland.
We report a rare case of epithelial-myoepithelial carcinoma (EMC) of the parotid gland. A 70-year-old man presented with a 4-months-history of right-sided subauricular swelling. Computed tomographic scans revealed a well-defined mass with cystic lesion, measuring about 40 mm in diameter, in the right parotid gland. Because the tumor occupied superficial lobe, he underwent superficial parotidectomy with preservation of the facial nerve. On the basis of the histological and immunohistochemical findings, the tumor was diagnosed as EMC. His post-operative course was uneventful, and he is currently free from disease 6 months after surgery. Diagnosis, clinical behavior and treatment of EMC are reviewed from perusal of the literature.
