Carcinosarcoma of the parotid gland with epithelial–myoepithelial carcinoma and pleomorphic sarcoma components

We report a case of true malignant mixed tumour (carcinosarcoma) of the parotid gland with epithelial–myoepithelial carcinoma and pleomorphic sarcomatous components in a 68-year-old woman. The pleomorphic sarcomatous component behaved aggressively with lymph node and distant metastases. The biological behaviour of the individual components in a malignant mixed tumour makes it difficult to diagnose. We could find no previous report of epithelial–myoepithelial carcinoma as a component of a carcinosarcoma of the parotid.
