Carcinosarcoma de novo of the parotid gland with unusual sarcomatous component

Salivary gland carcinosarcoma is an exceedingly rare and aggressive neoplasm composed of a mixture of carcinomatous and sarcomatous components, with either component capable of metastasis. Salivary gland carcinosarcoma can arise in pleomorphic adenoma (PA) or de novo. The present study reports a case of the parotid gland de novo carcinosarcoma, which contained salivary duct adenocarcinoma and sarcoma that resembled malignant fibrous histiocytoma (MFH). To the authors' knowledge, MFH as a component of salivary gland carcinosarcoma has been described only once in literature, and was combined with squamous cell carcinoma.
