Minor salivary gland tumors were clinicopathologically evaluated. Between 1990 and 2000, 31 patients with minor salivary gland tumors (10 males and 21 females between 12 and 75 years of age, mean age : 49.9 years) were treated in our department. Minor salivary gland tumors most frequently occurred in the palate in 19 patients, followed by 5 in the buccal mucosa, 4 in the lips, and 1 in the oropharynx. Histopathological examinations revealed 20 benign and 11 malignant tumors. Pleomorphic adenoma accounted for the majority (19 cases) of the benign tumors. Malignant tumors consisted of 3 mucoepidermoid carcinomas, 3 adenoid cystic carcinomas, 1 adenocarcinoma, 1 acinic cell carcinoma, 1 salivary duct carcinoma, 1 tubular adenocarcinoma, and 1 basal cell adenocarcinoma. All cases of benign tumors were successfully treated by extirpation without tumor recurrence. Of the 11 cases of malignant tumors, 7 were treated by surgery alone, 1 was treated by surgery after chemotherapy, and 3 were treated by surgery after chemotherapy and radiotherapy. Primary lesions recurred in 2 of these patients. The outcomes of patients with malignant tumors were as follows : 6 patients survived without other complications, 3 died of uncontrollable tumors, and 2 died of other diseases. Of the 3 patients who died of uncontrollable tumors, 2 died of primary lesions and 1 died of cervical lymph node metastasis.
