Fibro-osseous lesions (JOF) are benign mesenchymal skeletal tumors in which mineralized tissue, blood vessels and giant cells, in varying proportions, replace normal bone. It is an unusual fibro-osseous pathology that develops inside the craniofacial bones, predominantly in the paranasal sinuses. It is common in patients under 14-15 years of age. It's locally aggressive but histopathologicaly benign lesion. Though it mimics active ossifying fibroma, but aggressive in nature. Histological characteristics do not indicate the rate of growth or prognosis, treatment depends on the clinical and biologic behavior of the tumor. We report a case of juvenile ossifying fibroma, in a 13year-old boy. The treatment was radical en-bloc excision and 7years follow-up without recurrence.
