[The diagnosis and treatment of the epithelial salivary gland tumors in children and adolescents].

Sixty-six cases with epithelial salivary gland tumors in children and adolescents, who were less than 16 years old, were analized. Those cases accounted for 3.6% of all epithelial salivary gland tumors in our school. Twenty-five cases (37.9%) were benign tumors, among which pleomorphic adenoma was the most common. Forty-one cases (62.1%) were malignant tumors, in which mucoepidermoid carcinoma was the most common one. Three quarters of cases were in the group over 10 years old. Six cases were in the group less than 5 years old. Among them 5 cases were malignant tumors. The younger the children is, the more possible the malignant tumor is. Two cases with malignant tumors had the history of receiving radiotherapy because of the hemangiomas at the same locations. It indicates that the occurrence of the malignant tumors was related to radiotherapy before. The diagnosis, differential diagnosis and treatment of the tumors were discussed. The initial radical resection of the malignant tumors was emphasized.
