NORTH AMERICAN SOCIETY OF HEAD AND NECK PATHOLOGY COMPANION MEETING, MARCH 3, 2013, BALTIMORE, MARYLAND Fibro-Osseous Lesions of the Maxillofacial Bones

Abstract Fibro-osseous lesions of the maxillofacial bones should be classified based on their radiographic growth pattern. This method can simplify this category of lesions, which have considerable overlapping histologic features. These neoplasms can be grouped into three cat-egories: (a) fibrous dysplasia; (b) ossifying fibroma; (c) and osseous dysplasia. Important lesions in the differential diagnosis are osteoblastoma and giant cell reparative granuloma
