초록

Epithelial-myoepithelial carcinoma(EMC) is a rare low grade malignant salivary gland neoplasm that most commonly occurs in the parotid gland but can also arise in minor salivary glands. It is a distinct neoplasm characterized by tubular and solid growth patterns and a dual cell population including an inner larger of cuboidal to columnar epithelial cells which are peripherally bounded by a layer of myoepithelial cells with distinctly clear cytoplasm. The clinical course is characterized by a high incidence of local recurrence and not infrequent distant metastasis. The differential diagnosis included acinic cell tumor, adenoid cystic carcinoma, mucoepidermoid carcinoma, sebaceous carcinoma and pleomorphic adenoma. We report a case of EMC of left parotid gland in a 55-year-old woman.
