EPIDEMIOLOGIC ANALYSIS OF SALIVARY GLAND TUMORS OVER A 10-YEAR PERIOD DIAGNOSED IN A NORTHEAST BRAZILIAN POPULATION

Abstract

Objective: To analyze the clinical profile of a series of salivary gland tumors diagnosed in the state of Sergipe. Study Design: This is an epidemiologic, analytical, and retrospective study of the clinical characteristics of salivary gland tumors, carried out in medical/oral pathology reference services in the state of Sergipe. The cases were collected in the laboratories database. All cases of major and minor salivary gland tumors that met the diagnostic criteria established by the World Health Organization (WHO) and diagnosed between 2006 and 2016 were selected. Cases were diagnosed by fine needle aspiration; inconclusive reports and secondary tumors were excluded. Results: A total of 588 cases were found. The majority of tumors occurred in women (55.7%), ranging from 41 to 50 years of age (19.06%). Benign tumors were more common (79.5%), and major salivary glands were more affected (61.73%), particularly the parotid gland (51.7%). Pleomorphic adenoma (88.96%) and Warthin tumor (6.8%) were the most common benign tumors, whereas mucoepidermoid carcinoma (24.58%), not otherwise specified adenocarcinoma (20.34%), and adenoid cystic carcinoma (17.8%) were the most frequent malignant tumors. Conclusions: Pleomorphic adenoma and mucoepidermoid carcinoma were the most common benign and malignant salivary gland tumors, respectively, and the parotid gland was the most affected anatomic site.
