Abstract

Carcinosarcomas, also known as true malignant mixed tumors, are rare tumors of the salivary gland and are composed of both malignant epithelial and malignant mesenchymal elements. They may occur in pre-existing pleomorphic adenomas or arise de novo. Here we report the first case of carcinosarcoma of the parotid gland composed of mucoepidermoid carcinoma and osteosarcoma. The tumor had originated from the parotid gland and extended into the parapharyngeal space. To the best of our knowledge, there have been no reports on mucoepidermoid carcinoma mixed with osteosarcoma ex pleomorphic adenoma in the parotid gland.
