Recurrent ameloblastoma after 33 years of hemimandibulectomy: case report

Ameloblastomas are benign odontogenic tumors that exhibit a local malign behavior. Case report: A recurrence of an ameloblastoma occurring after 33 years of emimandibulectomy in a 69-year-old woman is reported. The tumor arose as a painless mass. Clinical exam showed a lesion placed in the right third molar region. The right mandible was absent from the bicuspid area to the condyle in radiography and computed tomography. After excision, microscopic features diagnosed an ameloblastoma. The patient is under close follow-up and shows no recurrence or metastasis. Conclusion: Despite the radical initial treatment, the tumor showed an uncommon behavior and recurred.
