Abstract :
Malignant mixed tumors of salivary glands are classified as three types: carcinoma arising in a pleomorphic adenoma, the most common; benign metastasizing pleomorphic adenoma; and carcinosarcoma (true malignant mixed tumor), which is very rare [Ann. Otol. Rhinol. Laryngol. (1982) 91 342]. In carcinoma, both epithelial and soft tissue elements are malignant. In the context of previous reports, we discuss a case of carcinosarcoma of the submandibular gland including the results of postmortem examination.
