The diagnosis of individual tumors was based on the World Health Organization classification.<br>Tumors were analyzed according to histological type, age, sex, site and size.<br>1.Benign tumors were observed in 68.3% of cases and malignant tumors were observed in 31.7%.<br>2.The most common type of tumor was pleomorphic adenoma (49.2%).<br>3.Pleomorphic adenoma occurred more frequently in female than in male patients. All the patients with Warthin tumors were male.<br>4.The peak incidence of salivary gland tumors was in the fourth and seventh decades and the average age of the patients was 53.4 years.<br>5.The incidence of salivary gland tumors was strikingly high in the palate (38.1%).
