Fibrous dysplasia is a rare bone disease that can affect one or many bones of the body. The severity of the condition can vary from person to person: some people have no symptoms at all while others may have a significant physical impairment, with the full spectrum in between being possible.

This condition is caused by a gene abnormality, which affects the bone forming cells.

A small number of sufferers have endocrine abnormalities and skin pigmentation marks associated with the bone condition : this is the McCune-Albright syndrome
