Abstract
Low-grade polymorphous adenocarcinoma (PLGA) is a malignant neoplasm featuring low aggressiveness and almost exclusively originated from minor salivary glands. In the oral cavity, the palate is the most common site for PLGA development and its typical presentation is that of an indolent growth that may be painful or even ulcerated. In this manuscript we report an additional case of PLGA that shared clinical and histological features with the pleomorphic adenoma, and discuss the main aspects for its correct diagnosis.

Resumo
O adenocarcinoma polimorfo de baixo grau (APBG) é uma neoplasia maligna de baixo nível de agressividade, que ocorre quase exclusivamente em glândulas salivares menores. Na cavidade oral, o palato é a localização mais comum para o APBG e sua apresentação típica é de crescimento indolente, ocasionalmente doloroso ou ulcerado. Este manuscrito objetivou relatar um caso adicional de APBG, que apresentou características clínicas e histológicas semelhantes àquelas do adenoma pleomórfico na biópsia incisional, bem como discutir os aspectos principais para o seu correto diagnóstico.
