HISTOPATHOLOGIC REVIEW OF MALIGNANT SALIVARY GLAND TUMORS

Abstract

Objective To describe the epidemiologic and histopathologic features of surgical specimens from patients with malignant salivary gland tumors. Study Design In this retrospective study, we evaluated and reclassified 34 cases of a general hospital, between January 2005 and January 2018. Results In this period, malignant salivary gland tumors were more common among females (56%) and parotid gland (67.6%) as the most affected site, followed by minor salivary glands (23.5%). The mean age was 43 years. Adenoid cystic carcinoma was the most common malignant salivary gland tumor (29%), followed by mucoepidermoid carcinoma (24%). There were 3 cases reclassified as secretory carcinoma and 1 case as adenocarcinoma not otherwise specified, according to the World Health Organization Classification of Head and Neck Tumors of 2017. Conclusions This study is relevant to obtain epidemiologic data of malignant salivary gland tumors due to few reports from our country.
