Extensive Type III unicystic ameloblastoma: A case report with conservative management

Abstract

Unicystic ameloblastoma is a distinct type of ameloblastoma that clinically and radiographically resembles a dentigerous cyst; however, on three-dimensional evaluation, it shows tumorous behavior and histopathologically shows ameloblastic epithelium. Compared to conventional ameloblastoma, it has a low recurrence rate after conservative treatment. We report a case of extensive unicystic ameloblastoma of mandible in a young male patient that showed tumorous characteristics on computed tomography (CT) and was treated conservatively by decompression. CT follow-up after 3 months showed significant bone formation. The lesion was then enucleated. Follow up at 8 months showed tremendous bone healing.
