Ameloblastoma is a benign odontogenic tumor that originates centrally within the jaw bone, and may very rarely occur in a peripheral area. We present a case of peripheral ameloblastoma in the maxillary gingiva.
The patient was a 70-year-old male who presented with a 15×15×10mm tumor on the gingiva of the right maxillary molar region. Radiographic examination showed no resorption of bone. Because the tumor was histologically diagnosed as ameloblastoma by tissue biopsy, the tumor was excised with a part of the maxilla under general anesthesia. According to the clinical and pathological features, a diagnosis of peripheral ameloblastoma was made. As of 12 months after the operation, no sign of recurrence has been observed.
