Long Standing Ameloblastoma Mimicking Residual Cyst: A Case Report

Unicystic ameloblastoma, constituting approximately 6% of all ameloblastomas, poses diagnostic challenges, particularly in distinguishing it from dentigerous cysts. This rare variant manifests with diverse clinical presentations, complicating accurate identification. Herein, we present a case initially misdiagnosed as a residual cyst, underscoring the imperative need for a comprehensive diagnostic assessment. The management involved complete enucleation, and subsequent excisional biopsy unveiled an Ackerman's type three variant.

This case report emphasizes the significance of recognizing long-standing unicystic ameloblastomas, which may manifest post-tooth extraction, initially misleadingly diagnosed as residual cysts.
