Fibrous dysplasia (radiopacity)
Characteristics
- Idiopathic replacement of bone with fibrous tissue.
- It can affect just one bone (monostotic) or multiple bones (polyostotic). Jaw involvement is common (especially the maxilla).
- Most common in adolescents and young adults.
- Clinical signs and symptoms: Painless, slow and progressive enlargement of the affected bone.
- Initially it appears as an ill-defined radiolucency then gradually fine trabeculae become evident to produce the typical “ground glass” or “orange peel” appearance.
