Malignant mixed tumor is an aggressive malignant neoplasm composed of heterologous malignant epithelial and stromal components. It is a rare neoplasm, accounting for 0.05 % of all salivary gland tumors and 0.16 % of all malignant salivary gland tumors. The tumor may occur in the background of a preexisting pleomorphic adenoma or may arise de novo. We report on an 84-year-old female who was diagnosed with carcinosarcoma on her left parotid gland. Microscopically, the tumor consisted of two components - mainly myxoid chondrosarcoma (75%), poorly differentiated carcinoma and a few remnants of benign pleomorphic adenoma in the periphery of the tumor.
