²Ministry of Health, Izmir Training and Research Hospital, Pathology Department, Izmir, Turkey Malignant peripheral nerve sheath tumors are rare in the head and neck region. A tumor arising in the intraparotid region of the facial nerve, suggestive of pleomorphic adenoma preoperatively is presented. Facial nerve was found to be involved by tumor intraoperatively, requiring total parotidectomy and sacrifice of the involved portion of the facial nerve. Adjuvant radiotherapy was given. Possibility of an unusual tumor must be kept in mind when dealing with parotid masses, even if the preoperative studies are suggestive of a pleomorphic adenoma.
