Polyostotic fibrous dysplasia is a form of fibrous dysplasia affecting more than one bone.
[2] Fibrous dysplasia is a disorder where bone is replaced by fibrous tissue, leading to weak bones, uneven growth, and deformity.
[3] McCune–Albright syndrome includes polyostotic fibrous dysplasia as part of its presentation.
