PURPOSE:To analyze the pathological types and composition ratios of tumors within the parotid gland in or-der to provide data for epidemiological support.METHODS:Patients diagnosed with parotid tumors were recruited from Shanghai Ninth People's Hospital,Shanghai Jiao Tong University School of Medicine between 2005 to 2022.The patient sex,age and tumor type were collected.RESULTS:Totally 13 649 cases were enrolled in this study.The patients'age ranged from 1 to 104 years,with the peak age occurring in the sixth decade.The male to female ratio was 1.3:1.Among of them,totally 11 008 were benign tumors(80.7％),and 2 641(19.3％)were intermediate/malignant tumors.A total of 12 856 cases(94.2％)originated from epithelium,while 454 cases(3.3％)from soft tissues and 339 cases(2.5％)from haematopoi-etic and lymphoid tissues.Among 12 228 cases of primary salivary gland tumors,totally 10 289(84.1％)of them were be-nign and 1 939(15.9％)were malignant.Pleomorphic adenoma and carcinoma ex pleomorphic adenoma were the most common benign and malignant subtype,respectively.Nasopharyngeal lymphoepithelial carcinoma was the most prevalent among different types of metastatic tumors to the parotid gland.The most common soft tissue and haematopoietic and lym-phoid tissue tumor in the parotid gland were Schwannoma and extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue lymphoma(MALT lymphoma).CONCLUSIONS:In southeastern region of China,parotid tumors,pleo-morphic adenoma and carcinoma ex pleomorphic adenoma are the most common benign and malignant tumors of the parotid gland.The most prevalent soft tissue tumors and lymphoid hematopoietic system tumors are Schwannoma and MALT lymphoma,respectively.
