An epithelialmyoepithelial carcinoma of the parotid gland

A case report

Abstract

The epithelial-myoepithelial carcinoma is generally thought to originate in the intercalated portion of the ductal structures and constitutes about 0.5% of all epithelial salivary gland tumors. A case of epithelial-myoepithelial carcinoma arising in the parotid gland is reported. The patient is a 61 year-old woman, who complained of a mass in the left infraauricular region for five years. The size of the mass was about 7.5×6.5cm. The patient underwent extended total parotidectomy with postoperative irradiation of 60Gy. Histopathological and immunohistochemical examinations established a diagnosis of epithelial-myoepithelial carcinoma. The patient has been followed-up on outpatient bases and is free from local recurrence.
