Salivary gland carcinosarcoma: true malignant mixed tumor.
True malignant mixed tumor, or carcinosarcoma, of salivary gland origin is rare. Only 19 cases have been reported in the literature and a review of cases seen at the University of Iowa over the last 60 years yielded only two. In one case the mesenchymal component of the tumor contained both osteosarcoma and chondrosarcoma. In the second case, the history and the histology suggest a progression from carcinoma ex pleomorphic adenoma to a carcinosarcoma. These features are documented in this report and literature review.
