Abstract

Background: Salivary gland tumors (SGT) are one of the most complex human neoplasms, demonstrating variations in their clinicopathological profile related to racial and geographic differences. Few studies with large samples have been reported in Iran. We here investigated a large group of patients in southern Iran. Materials and Methods: In this retrospective study, all cases of primary epithelial salivary gland tumors, which had been recorded in a 5 years period from 2005-2009, were enrolled. Clinical data such as histopathologic type and site of the lesion as well as patients' age and gender were analyzed. Results: Data of 366 cases of SGTs were recorded. Pleomorphic adenoma (80.2%) and adenoid cystic carcinoma (46.6%) were the most common benign and malignant neoplasms. Male to female ratio (M/F) and the mean age of patients were 1:1.05 and 37.7 for benign tumors while they were 1.2:1 and 50.6 for malignant tumors, respectively. Parotid and minor salivary glands were involved more frequently. Conclusions: Although the salivary gland tumours encountered were similar in most of their characteristics to those reported in other countries, some differences such as relative frequency and age and gender prevalence were discovered. These findings should help surgeons and pathologists for more accurate diagnosis, management and treatment.
