One hundred and thirteen parotid tumors were excised in our hospital from May 1987 to December 1993. Pleomorphic adenoma was the most common tumor (41%), followed by adenolymphoma (Warthin's tumor; 25%). Of the 130 tumors, 18 (14%) were malignant: two mucoepidermoid tumors, one adenoid cystic carcinoma, 11 adenocarcinomas, one undifferentiated carcinoma and three malignant lymphomas. The percentage of Warthin's tumors was much higher than in previous reports and it was the most frequent tumor in males. The recent increase of Warthin's tumors may be due to changes in the age distribution of the population and to advances in medicine.
