A Malignant Solitary Fibrous Tumor of the Parotid Gland: A Case Report

A Solitary Fibrous Tumor (SFT) is a soft tissue tumor that appears exceedingly rare in the parotid gland. The literature review suggested that approximately 12%-22% of these cases behave aggressively. Besides, only 4 cases of histological malignant parotid gland SFT are reported in the English literature. We presented a 65-year-old cigarette-smoker man with a fix and tender mass over the left parotid and submandibular areas. On physical examination, the marginal branch of the facial nerve was paralyzed. The left total parotidectomy and neck dissection levels 1 and 2 were performed with preoperative embolization procedure and adjuvant radiotherapy for the patient. The results of the follow-up examination were unremarkable after 11 months. In this case report, we aimed to increase awareness on SFTs, although rare, among clinicians and pathologists. Accordingly, it should be considered in the differential diagnosis of soft-tissue tumors in the major salivary glands for better management.
