Juvenile ossifying fibroma. Report of four cases.
The present investigation concerns 4 patients with juvenile ossifying fibroma (JOF) whose data are analyzed together with 30 cases from the literature. The tumour mainly occurs in juveniles, 79% of the patients being 15 years or younger. Radiologically as well as at surgery, the lesion is demarcated from its surroundings. Histologically, JOF is unique in showing a loose-fibroblastic stroma that contains garland-like strands of osteoid with entrapped osteoblasts, the latter feature not being observed in other fibro-osseous lesions. JOF responds very well to conservative treatment that provided permanent cure in all cases with adequate follow-up data.
