Abstract
To evaluate the types and distribution of tumors of salivary glands in north Jordanians.
The records of the Department of Pathology at Jordan University of Science and Technology were reviewed for patients who were treated for salivary gland tumors from 1991 to 2002. The tumors were analyzed for age of patient, sex of patient, tumor site, and tumor type.
One hundred two true neoplasms (70% benign and 30% malignant) were found. The most frequent benign and malignant neoplasms found were pleomorphic adenoma (54%) and adenoid cystic carcinoma (13%), respectively. The most common major and minor salivary gland sites were the parotid (51%) and palatal glands (20%), respectively. Although most of major gland tumors were adenomas, carcinomas of the minor glands were only slightly less frequent than adenomas. The most frequent malignant parotid tumors were adenoid cystic carcinoma and mucoepidermoid carcinoma. The most frequent minor salivary gland malignant tumors were palatal adenoid cystic carcinoma. Age ranged from 1 to 94 (mean 40) years, with a male to female ratio of 1:1.2.
North Jordanians with salivary gland tumors were found to have similar characteristics with patients of other countries with regard to tumor type, tumor site distribution, and age and sex of patients.
