CAMARA, Priscilla Rodrigues et al. Adenomatoid odontogenic tumor: case report emphasizing the main differential diagnoses. Rev. Bras. Odontol. [online]. 2016, vol.73, n.4, pp. 348-352. ISSN 1984-3747.

Objective: to report a case of adenomatoid odontogenic tumor (AOT), highlighting its features and differential diagnosis. Case report: a 16-year-old male with a unilocular radiolucent lesion involving the unerupted 24th tooth. Considering AOT, dentigerous cyst, calcifying cystic odontogenic tumor, and unicystic ameloblastoma as the clinical diagnoses, an excisional biopsy was performed. Microscopic analysis revealed a parenchyma containing tubular structures and roset-like areas, establishing a diagnosis of AOT. Conclusion: the acknowledgement of clinical, radiographic, and microscopic features of AOT is essential to guide a definitive diagnosis and, as a consequence, to enable a suitable treatment of the patient.
