Peripheral ameloblastic fibroma.

Peripheral ameloblastic fibroma is an exceedingly rare lesion. Only three reports could be found, two of which appeared in the Japanese literature. Here, we report a case of peripheral ameloblastic fibroma occurring in a 5-year-old girl. The diagnosis was made after careful microscopic examination, to exclude other lesions. The lesion was excised and has not recurred 1 year after removal.
