The present case describes the clinical and histopathologic features of a benign myoepithelioma of the parotid gland. A 70-year-old woman presented with clinical symptoms of a unilateral, gradually developing, preauricular swelling. Examination revealed a 7x5 cm tumor in the area of the left parotid gland. The tumor was removed and sent to the pathology department. A diagnosis of myoepithelioma was established. Myoepitheliomas of salivary glands are extremely rare, comprising approximately only 1% of all salivary gland tumours.Their histopathologic features, immunohistochemical findings, and clinical behavior are not well characterized. Together with the literature, consideration are presented on the histopathologic evaluation, differential diagnosis of these lesions
