The 142 cases of salivary gland tumors treated in our department during the past ten years were reviewed clinicopathologically. Major salivary gland tumors were found in 124 cases with 110 cases of parotid tumors and 14 cases of submandibular gland tumors. Minor salivary gland tumors were found in only 18 cases. Pleomorphic adenoma was the most predominant tumor in the salivary glands accounting for 59%of all cases. There were malignant tumors in 15% and 56% of major and minor salivary glands respectively, indicating the high incidence of malignancy in the minor salivary gland. Among the malignant tumors of the minor salivary were 3 gland cases of adenoid cystic carcinoma which was found only in one case of the major salivary gland. Compared to the benign tumors, more malignant tumors which were larger were found in elderly males. Malignant tumors were accompanied by facial palsy and pain with a high incidence only in the parotid gland. In the submandibular and minor salivary glands, the small number of cases did not reveal any differences in rates of these complications.
