[Fibrous dysplasia of bone and osteofibrous dysplasia. Focusing].

Abstract

This is a review article on fibrous dysplasia of bone. All aspects of this condition including, macroscopic and histologic findings, lesion distribution, clinical, radiological and biological findings as well as evolution and treatment are discussed. A classification of skeletal lesions based on then appearance on plains films and computed tomography is proposed; 3 radiological types are differentiated: non-expanding bone lesions, expanding lesions with a thick periosteal reaction and expanding lesions with a thin periosteal shell. Main features of osteofibrous dysplasia are also discussed.
