Abstract

Abstract: Objective:To investigate the diagnosis and prognosis of one patient with carcinoma ex pleomorphic adenoma (CXPA) composed of three malignant components in parotid gland, and to raise the clinicians' awareness of the disease. Methods:A patient was presented to hospital because of the mass in left parotid gland region for more than 30 years and the accompanied pain lasted for one month.After color ultrasonography,the left parotid gland tumor resection was performed. Results:The operation was successful.The postoperative pathological diagnosis results comfirmed as CXPA, it was composed of three malignant components, including non-specific adenocarcinoma, ductal carcinoma, and myoepithelial carcinoma. Conclusion:CXPA composed of three malignant components at the same time are extremely rare.CXPA is difficult to diagnose and its prognosis is poor.The clinicians are supposed to improve the understanding of CXPA.

Key words: duct neoplasms, carcinoma ex pleomorphic adenoma, non-specific adenocarcinoma, myoepithelial neoplasms, pleomorphic adenoma
