Review of Fibro-Osseous Lesions of Jaw

The fibro-osseous lesions of the jaws comprise adiverse, interesting, and challenging group of conditionsthat pose difficulties in classification andtreatment. Common to all is the replacement ofnormal bone by a tissue composed of collagen fibersand fibroblasts that contain varying amounts ofmineralized substance, which may be bony or cementum-like in appearance1,2,3,4,5,6. Many lesions contain an admixture of these calcifications. Fibro-osseous lesions (FOLs) of the craniofacial bones comprise a group of lesions composed of hypercellular fibrous elements and osseous elements, both of whichexhibit a wide spectrum of variations. The majority of FOLs have overlapping histologic features, so the proper diagnosis requires good correlation of the history, clinical, and radiographic findings and histologic features.
