Description
Summary:Odontogenic tumors constitute a group of lesions with varied histogenesis and biological behavior. We describe the case of a 15-year-old female patient with an asymptomatic lesion in the anterior mandible discovered incidentally in routine radiographic examination. A well-defined, unilocular radiolucent lesion was found between teeth 42 and 43. Clinical diagnosis was odontogenic cyst, and the lesion was treated by enucleation. Microscopic examination revealed a benign epithelial odontogenic neoplasm, constituted by spindle, cubic, and columnar cells, arranged in islands, cords, rosettes, and duct-like structures, in a fibrous stroma. Clinicopathologic characteristics led to the diagnosis of adenomatoid odontogenic tumor (AOT). We emphasize that the knowledge concerning histopathologic features of AOT contributes to a correct diagnosis and appropriate treatment. Given its favorable prognosis, AOT should be treated by conservative surgical approaches.
