A case of ameloblastoma with a trend toward rapid growth in an elderly patient is reported. The patient, a 71-year-old woman, was referred to our clinic for swelling of the right premolar region of the mandible. At presentation, a well-circumscribed bony hard swelling (22×15mm) was observed at the right premolar gingiva. On X-ray examination, a radiolucent lesion was found between the right lateral incisor and the first premolar, accompanied by a honeycomb-like lesion at the alveolar process of the right premolar region of the mandible. Under the diagnosis of an odontogenic tumor, tissue biopsy was performed, and the lesion was histologically diagnosed as an ameloblastoma. Before surgery, the radiolucent lesion had extended between the left central incisor and the right second premolar region. Therefore, marginal resection from the left lateral incisor to the right first molar of the mandible was performed under general anesthesia. Histopathological examination revealed a follicular type of ameloblastoma with no evidence of malignancy. No recurrence was observed for 2 years 10 months after surgery, but the patient died of hepatocellular carcinoma.
