The author has studied clinically and pathologically on 62 cases of minor salivary gland turmors collected from Department of Oral Pathology, College of Dentistry, Seoul National University, during the period of september, 1958 to April, 1976. The results were as follows; 1. In 62 cases of minor salivary gland tumors, 33 cases (53.2%) were in male and 29 cases (46.8%) were in female. 2. The age distribution showed a peak in the group of 4th decade (25.8%), and average age of patients in benign tumors was 40.1 years old, malignant tumors was 47.9 years old. 3. As to the distribution of minor salivary gland tumors, predominent location was in the palate revealing 31cases (50.1%), and buccal mucosa 9(14.5%), retromolar area 8(12.9%), lip 5(8.6%), tongue 3(4.8%), floor of mouth 2(3.2%), and miscellaneous 4(6.5%). 4. In the 62cases of minor salivary gland tumors, 32 cases(54.8%) were benign and 28 cases(45.2%) were malignant tumors. The chief complaints of patients were almost always painless progressive increased masses. 5. In the 62 cases of minor salivary gland tumors, the highest incidence was 33 cases (53.2%) of pleomorphic adenomas, and next was 9 cases (14.5%) of mucoepidermoid carcinomas, each 6(9.7%) of malignant pleomorphic adenomas and anaplastic adenocarcinomas, 5(8.1%) of adenoid cystic carcinomas, each one (1.6%) of acinic cell adenomas, malgnant oxyphlic adenoma and papillary cyst adenocarcinoma. 6.
