Ossifying fibroma is one of a group of fibro-osseous lesions which are rarely seen in the long bones.
The patient reported here is a 15-year-old female whose tibia and fibulla is affected.
Seventy-four cases have been reported from 1966 to 1984 throughout the world (Japan: 25, Other countries: 49).
