A Rare Variant of Ameloblastoma Emulating as a Gingival Overgrowth: A Report of Two Cases

Peripheral ameloblastoma is a rare, benign odontogenic tumor that arises in the soft tissues of the oral mucosa. We present two cases of peripheral ameloblastoma located on the mandibular alveolar ridge, each manifesting as a painless, firm, exophytic mass initially suspected to be a reactive granulomatous lesion. Notably, the first case occurred in a patient with a prior history of intraosseous ameloblastoma in the same region, which makes this presentation clinically significant and raises important considerations regarding tumor pathogenesis and potential recurrence. Histopathological examination confirmed the diagnosis of peripheral ameloblastoma. Wide local excision was performed as the treatment of choice in both cases. The report of these cases highlights the importance of including odontogenic tumors in the differential diagnosis of persistent gingival overgrowth and highlights the need for histopathological evaluation to ensure accurate diagnosis and management.
