Polyostotic fibrous dysplasia
Polyostotic fibrous dysplasia is a form of fibrous dysplasia affecting more than one bone. Fibrous dysplasia is a disorder where bone is replaced by fibrous tissue, leading to weak bones, uneven growth, and deformity.
McCune-Albright syndrome includes polyostotic fibrous dysplasia as part of its presentation. When polyostotic fibrous dysplasia manifests in the long bones, limping results; when it manifests in the face, asymmetric growth of the face can result.
One treatment that has been used is bisphosphonates.
