Introduction: According to the National Cancer Registry, head and neck cancers account for 5.5 to 6.2% of all malignancies, which translates into about 5,500 to 6,000 new cases per year. Salivary gland tumors are a heterogeneous group of cancers, which results from the complex embryogenesis of salivary glands; they are divided into benign and malignant tumors. Common benign tumors include mixed tumors and Warthin tumors. Carcinosarcoma is called a true malignant mixed tumor because the tumor process involves both epithelial and mesenchymal elements. We reported the case of true malignant mixed tumor comprising three components: adenocarcinoma, synovial sarcoma (80%) and osteosarcoma (20%). This tumor develops rapidly and has an adverse course with a tendency to form metastases.
Case report: The work presents a case report of a 65-year-old patient who reported to the Department of Otolaryngology, ENT Oncology, Audiology and Phoniatrics at the WAM Hospital due to a tumor of the right parotid gland. The patient was concerned with the rapid growth of the tumor that occurred within 2 months prior to hospitalization, causing deformation of facial features. ENT examination revealed a polycyclic tumor with limited mobility and asymmetry of the corners of the mouth (lowering on the right side). FNA diagnosed typical cancer cells suggesting malignant growth. The patient was qualified for surgical treatment. Under general anesthesia, the right parotid gland tumor with superficial lobe of the salivary gland and region II cervical lymphadenectomy on this side were removed. The postoperative course was normal. Postoperative histopathological examination described high -rade malignant parotid carcinoma, pT3Nx. The patient was referred to an oncology center to undergo radiotherapy.
