          Abstract

          The adenomatoid odontogenic tumor (AOT) is a benign, non-invasive lesion with a slow but progressive growth. This tumor has three variants: follicular, extrafollicular, and peripheral. The extrafollicular type is an intraosseous lesion that is not associated with unerupted teeth. Radiographically, it appears as a well-defined, unilocular, round or ovoid radiolucency with multiple, small, irregular radiopaque foci. Microscopically, it is characterized by nodules of cuboidal or columnar epithelial cells that form nests, rosette or duct-like structures (with minimal stromal connective tissue), and acellular calcifications. This article presents the case of a 35-year-old man with a lesion on the anterior mandible. Clinical and radiographic features indicate that this lesion is an extrafollicular variant of AOT.
