Myoepithelioma of the Parotid Gland: A Case Report

ABSTRACT

PURPOSE: Myoepithelioma is a rare tumor that originates exclusively from myoepithelial cells of the salivary glands, breast and the prostate. Myoepithelioma accounts for less than 1% of all salivary gland tumors. The objective of our study is to present our experience of the infra- auricular mass which was finally diagnosed as a myoepithelioma. METHODS: A 54-year-old woman was presented with a firm, movable, slow-growing infra-auricular mass with 3 cm in diameter. MRI scans and fine needle biopsy was performed for preoperative diagnostic study. A superficial parotidectomy was preceded and removed tumor successfully. RESULTS: Histopathological study revealed a myoepithelioma of plasmacytoid type. Patient's postoperative course was uneventful without any complication and had no evidence of recurrence of tumor for 9 months follow- up period. CONCLUSION: Myoepithelioma in the parotid gland shows similar clinical courses and intraoperative finding to the pleomorphic adenoma and superficial parotidectomy was selective choice for treatment.
