Abstract
During a 30-year period 24 epithelial salivary gland tumors were diagnosed in children and adolescents less than 18 years of age. The cases were retrieved from a series of 759 consecutive cases of salivary gland tumors (3.2%) from the area corresponding to southern Portugal during the same period of time. The mean age of the patients was 13.4 years, and one case was congenital. There was a slight female predominance (male/female ratio 1:1.7). The parotid gland was affected in most cases (70.8%). Seventeen neoplasms were benign, and the remaining seven were malignant. As in the adult group, pleomorphic adenoma was the most frequent benign tumor (66.6%), with similar histologic findings and clinical course. Mucoepidermoid carcinoma was the prevalent malignant tumor (20.8%), had a high grade of differentiation, and had a favorable outcome. The histologic pattern of the congenital neoplasm was similar to that of adult epithelial-myoepithelial carcinoma.
