Abstract
Epithelial-myoepithelial carcinoma (EMC) is a low-grade malignant salivary gland neoplasm that was first described in 1972. EMC occurs in the older age group, there is a female predilection and mainly involves the parotid gland. Most authors recommend superficial parotidectomy as a treatment for low-grade malignant tumor in the superficial lobe of parotid gland. The treatment of epithelial-myoepithelial tumors typically includes surgical excision aimed at achieving a R0 resection. This paper reports a case of EMC of the parotid gland treated only by a conservational surgical excision. The lesion was exposed by the retromandibular approach and detached. After the parotid gland envelop was exposed, the mass was observed and was easy to remove due to capsulation. The preoperative diagnosis was a pleomorphic adenoma on the left parotid gland. The tumor was removed surgically with a conservative extracapsular dissection. The postoperative diagnosis was EMC, so superficial parotidectomy or radiation therapy was considered. Nevertheless, the patient was observed and no additional treatment was attempted because the patient was old and a successfully excision of the tumor had been achieved.
