Large ameloblastic fibro-odontoma in a 3 yearold child: case report

Resumo

The ameloblastic fibro-odontoma is a rare mixed
neoplasm composed of proliferating odontogenic epithelium,
ectomesenchymal tissue, and varying degrees of dental hard tissue
formation. The mean age of the incidence is from 8-12 years and
there is no gender or anatomic site predilection, but it is most
commonly found in children’s or teenager’s jaws. Case report: A
3-year-old female patient showed a swelling in anterior maxilla,
with facial asymmetry. Radiographically, it presented as a mixed
lesion with undefined limits. Clinical hypothesis was odontoma.
Enucleating surgery was conducted with tooth germs preservation.
The final diagnosis was ameloblastic fibro-odontoma. No recurrence
was observed at 1-year follow-up period, and the permanent tooth
germs were correctly positioned for eruption. Conclusion: Although
ameloblastic fibro-odontoma is a benign lesion, it developed in a
very early age, with rapid growth and destruction of cortical bone.
Proper surgical enucleation allowed the teeth maintenance.
