Abstract
A myoepithelial carcinoma, a rare malignant salivary gland neoplasm, occurs mostly in the parotid gland. The incidence of myoepithelioma is less than 1% of all salivary gland tumors, and malignant myoepithelioma is even more rare. Biological behavior of myoepithelial carcinoma has not been fully clarified. Malignant myoepithelioma shows clinicopathologic diversity and presents with various stages of myoepithelial differentiation. The definite treatment for malignant myoepithelioma is surgical excision, and the role of radiation therapy and chemotherapy is not yet established. In this study, we have experienced two patients with malignant myoepithelioma of the parotid gland who were treated with surgical excision.
