Abstract
A case of pigmented ameloblastic fibrodentinoma and one of pigmented ameloblastic fibroodontoma, both arising in the mandible, are reported.
Case 1. An 8-year-old girl visited our clinic for further evaluation of a radiolucent area in the left side of the mandible, found by a dentist. Radiographic examination demonstrated a circumscribed radiolucent mass at the root apex of the left second deciduous molar. The clinical diagnosis was a mandibular cyst. The lesion was removed with the patient under intravenous sediation. A postoperative pathological examination disclosed a pigmented ameloblastic fibrodentinama. Reexamination 7 years after the operation revealed no recurrence of the lesion.
Case 2: A 10-year-old girl presented with delayed eruption of the right mandibular first molar. Radiographs revealed a multicystic radiolucent lesion, which contained some small radiopaque masses from the right second premolar to the acending ramus. The clinical diagnosis was a mandibular tumor. The tumor was extirpated with the patient under general anesthesia. The postoperative histopathological diagnosis was a pigmented ameloblastic fibroodontoma. There has been no evidence of recurrence as of 2 years 4 months postoperatively.
