| Abstract: | Adenoid ameloblastoma with dentinoid is an uncommon benign odontogenic neoplasm, and its unicystic variant seems to be even rarer. A 34-year-old man was referred for evaluation of an asymptomatic swelling in the posterior maxilla. Intraoral examination showed an expansive lesion, soft to palpation, covered by a normal color mucosa. Cone beam computed tomography revealed a well-defined unilocular hypodense tumor involving the left maxillary sinus. Histopathological examination of the surgically excised specimen showed a cystic tumor lined by an ameloblastic-like epithelium containing columnar basal cells with hyperchromatic and polarized nuclei. In some areas of the capsule, the tumor showed mural infiltration by sheets of cells containing central whirling structures. Dentinoid material was also observed in association with ameloblastic-like cells. The tumor was BRAF and KRAS wild-type. Collectively, these findings were consistent with the diagnosis of a unicystic variant of adenoid ameloblastoma with dentinoid. |
