Abstract
Oral minor salivary gland tumors are uncommon lesions. This study determined the distribution and demographic features of oral minor salivary gland tumors (OMSGTs) in a Rio de Janeiro population. Methods: Clinicopathological features of 172 cases of OMSGTs diagnosed between 1942 and 2012 were taken from the files of two oral pathology services and reviewed. Results: Eighty-eight tumors were benign and 84 were malignant. Mean patient age was 51 years, and most of the patients were females. The palate was the most common location (56.4%). Pleomorphic adenoma (PA) (44%), mucoepidermoid carcinoma (MEC) (13%), and polymorphous low-grade adenocarcinoma (PLGA) (13%) were the most frequent neoplasms. Conclusion: The present data confirm PA, MEC, and PLGA as the most common OMSGTs. Epidemiological data of OMSGTs in specific populations can be of great interest for a better understanding of its biology and clinicopathological features.
