【 摘 要 】

True mixed malignant tumors (carcinosarcomas) account for an extremely small proportion of salivary malignancies and are marked by aggressive growth rates, frequent local recurrence, and distant metastases. We report a case of 1 such tumor arising from a biopsy-proven pleomorphic adenoma, which was treated with surgical resection, free flap reconstruction, and adjuvant radiation therapy.
