Minor salivary gland tumors are rare, and we experienced 6 cases in 5 years. The occurrence rate this type of tumor was 9.1％ of all patients with salivary gland tumors. The patients included 3 male and 3 female, the average age was 61.3 years with a range of 47 to 84 years. Three of 6 cases had a tumor in the hard palate, the other patient had a tumor in the tongue, the nasal septum, and the upper lip. Histopathological examination revealed that 3 cases were pleomorphic adenoma, two cases were carcinoma ex pleomorphic adenoma, and one case was papillary cystadenocarcinoma. Because minor salivary gland tumors tend to be malignant, it is extremely important to resect the tumor en bloc in the first operation.
Key words : minor salivary gland tumor, pleomorphic adenoma, carcinoma ex pleomorphic adenoma,
