摘　　要：BACKGROUND Salivary carcinosarcoma is an extremely rare tumor containing both malignant epithelial and mesenchymal constituents.This article reports a rare case of carcinosarcoma with salivary duct carcinoma and osteosarcoma as the tumor components.The clinicopathological characteristics,treatment,and prognosis are discussed in conjunction with the literature.CASE SUMMARY A 48-year-old man presented with a complaint of a mass in the right parotid region.Osteosarcoma was first considered for assessment by fine-needle aspiration cytology.Physical examination revealed a mass measuring approximately 4 cm×3.5 cm×3 cm.The mass,the whole lobe of the right parotid gland,and the right mandible were completely removed during surgery.Postoperative histopathology confirmed carcinosarcoma of the salivary gland.CONCLUSION A definite diagnosis of salivary gland carcinosarcoma can only be obtained after complete surgical resection.
