Resumo: Adenomatoid odontogenic tumor (AOT) is a distinct benign odontogenic tumor, with relevant studies indicating that a cystic component is not uncommon; however, controversy still exists regarding its true nature. In fact, interesting studies indicate that a cystic component can be found between 41% and 56 % of AOTs. In these cases, dentigerous cyst (DC) diagnosis must be carefully excluded. Relevantly, to date, about 43 cases diagnosed as AOT arising in DC have been reported. Here, we show an interesting case of follicular AOT affecting the maxilla of a 13-year-old girl, which was predominantly cystic with intraepithelial calcified deposits, including histomorphological changes of its basal and parabasal layers, in close connection with typical AOT nests, the same ones that looked like detach or originate from this cystic component. Our findings suggest that the cystic component can be part of the tumor in an AOT subgroup, which should also be considered.
