juvenile ossifying fibroma

Wednesday 2 June 2010

definition: Juvenile ossifying fibroma (JOF) is an uncommon fibro-osseous lesion occurring in the facial bones. It is highly aggressive and has a strong tendency to recur. It has been recognized as a separate histopathological entity among the fibro-osseous group of lesions. Surgical resection is the preferred line of treatment.

Juvenile ossifying fibroma (JOF) is a fibro-osseous lesion that occurs in the facial bones. It is also called aggressive ossifying fibroma due to its aggressiveness and the high tendency to recur, unlike other fibro-osseous lesions, such as cemento-ossifying fibroma, which it may resemble radiographically.

Due to its distinct histological features, it has been recognized as a separate histopathological entity among the fibro-osseous group of lesions.
