Primary malignant mixed tumor of the mandible

Abstract

Tumors of aberrant salivary gland origin can involve the jaws and present as primary bone tumors of the mandible. Examples of such tumors are cylin-dromas, mucoepidermoid carcinomas and adenocarcinomas. The most common tumor of the salivary gland, the mixed tumor, has not been previously reported in the jaw. The case reported here is that of a primary bone tumor showing light, histochemical, and ultrastructural features of a malignant mixed tumor.
