Ossifying fibroma is a rare benign tumor of nondental origin. Fibroma of this type is mixed with osseous elements in varying amounts. It has been described as ossifying fibroma, osseous fibroma, fibro-osteoid osteoma, central osteoma, sclerosing fibroma, hypertrophic localized osteitis, localized osteodystrophic fibroma and localized osteitis fibrosa.1 Ewing2 called this type of growth secondary osteoma since it appears as a result of secondary ossification of the connective tissue.
