Benign nonodontogenic fibro-osseous lesions of the skull

摘要: Abstract Fibrous dysplasia is defined as a disease of bone, characterized by localized areas, usually in unilateral distribution, showing maturation arrest bone formation at the stage woven bone. This definition agreement with histologic findings uncomplicated lesions polyostotic fibrous dysplasia. The diagnosis has prognostic implications that are lacking other fibro-osseous which it may be confused. Juvenile ossifying fibroma (benign osteoblastoma) localized, actively growing, destructive lesion occurring predominantly children and microscopically trabeculae focal lamellar replacement cellular, basophilic, stroma. Osteoblastic hyperplasia prominent osteoma slow-growing predominance but also fibrous, acidophilic Some these growing rapidly show numerous thus resemble or examples mature into osteomas. On hand, all osteomas would probably called if biopsied an early stage. inherent pattern found growth active abundance process subsides replaced Each should recognized distinct entity, them not grouped under general heading
