A 1-year-old boy with an ameloblastic fibro-odontoma in the anterior mandible is presented.
Ameloblastic fibro-odontoma is a rare odontogenic tumor composed of epithelial cells and mesenchymal stroma derived from tooth germ cells.
The patient visited our clinic for swelling on the right incisal region of the mandible. Hard swelling of the alveolar bone was found. Radiographic examination demonstrated a cystic radiolucent area with radiopaque mass-like teeth. On December 12, 1991, the mandibular tumor was extirpated under general anesthesia. Microscopically, the tumor was composed of primitive connective tissue resembling dental pulp and odontogenic epithelium as well as enamel, dentin, and tooth germ. This lesion was histologically diagnosed as ameloblastic fibro-odontoma. This case has been followed-up for 2 years 6 months and there has been no evidence of reccurence.
