Salivary gland tumors are important lesions in head and neck pathology. Although uncommon, they are not rare. As reported in studies, the annual incidence in the world is around 1 to 6.5 cases per 100,000. Most of these tumors occur in major salivary glands and are of epithelial origin. In minor salivary glands, these neoplasms range from 9% to 23% (de Lima et al., 2015). The great diversity of histological types, including the new entities recently described, makes it difficult to appreciate clinical and demographic aspects of salivary gland neoplasms.Brazil is a country with continental dimensions that have geographic and cultural variations. Studies show a frequency of salivary gland tumors in the Brazilian population between 0.25% and 2.6% (da Silva et al., 2018;Loiola et al., 2009), with malignant lesions being responsible for 28.9% to 57.7% of lesions in minor salivary glands, according to the region analyzed (Cunha et al., 2020;da Silva et al., 2018).
