[Juvenile ossifying fibroma: a misgiving tumor of the jaws].
Juvenile ossifying fibroma is a rare benign tumour of childhood. It is hardly distinguishable from others fibro-osseous lesions because of their overlapping microscopic features. Juvenile variant of ossifying fibroma may be mistaken for malignancy, particularly osteosarcoma. Radiology is central to their diagnosis because of the very limited nature of the tumour. Microscopically, the lack of cytologic atypia or abnormal mitosis, and the presence of bone maturation or cementum deposits are consistent with an ossifying fibroma. This entity should be kept in mind regarding any bone lesion jaws in children.
