Fibrous dysplasia

What causes fibrous dysplasia?

We don't really know. No consistent familial or hereditary factors have been identified. However, a genetic mutation has been identified in patients with McCune-Albright syndrome. The polyostotic and McCune-Albright forms affect more girls than boys.

What are the symptoms of fibrous dysplasia?

Children experience fibrous dysplasia in a wide range of severity. Some experience many symptoms associated with endocrine abnormalities, while others appear entirely healthy, with little or no evidence of bone or endocrine involvement.

Here are some symptoms your child may be experiencing:

• bone pain
• difficulty walking
• deformities of the leg or arm
• limb length discrepancy
• light to dark brown skin lesions or pigmentation

The symptoms of fibrous dysplasia may resemble other medical conditions or problems. Always talk to your doctor for a diagnosis.
