Abstract

Purpose: Epithelial-myoepithelial carcinoma (EMC) represents about the 1% of the malignant neoplasms in the salivary glands and clinically most commonly found localized, well defined and sometimes presents orofacial pain. Treatment of choice is surgical excision. Postoperative radiotherapy can be used when surgical margins are doubtful. We report our experience of EMC of the parotid gland. Methods: A 78-year-old man presented with a three-year history of a localized, painless, $7{\times}6cm$ sized recurred tumor in his right preauricular area. He was diagnosed as EMC of the right parotid gland. So a total parotidectomy was performed. In his old medical history, he had a mass in the same area 5 years ago. The diagnosis of pleomorphic adenoma was made and the mass excision was performed at the local clinic without further evaluation. Results: It was unable to visually discriminate between the tumor and the normal tissue. So a total parotidectomy was performed. The patient was got post-operative radiotherapy and was followed up for 9 months. There was no specific evidence of recurrence. Conclusion: We present a case of EMC of the parotid gland in right preauricular area, which is uncommon. So we report a uncommon case of EMC to discuss about our experience with relevant journal discussion.
