چکیده
alivary gland carcinosarcoma is an exceedingly rare and ggressive neoplasm composed of a mixture of carcinomaous and sarcomatous components, with either component apable of metastasis. Salivary gland carcinosarcoma can rise in pleomorphic adenoma (PA) or de novo.1 The present study reports a case of the parotid gland de ovo carcinosarcoma, which contained salivary duct adenoarcinoma and sarcoma that resembled malignant fibrous istiocytoma (MFH). To the authors’ knowledge, MFH as component of salivary gland carcinosarcoma has been escribed only once in literature, and was combined with quamous cell carcinoma.2
