ICD-Code Q78.1: Polyostotic fibrous dysplasia
You have a condition that causes changes to the tissue in multiple bones.
In the bones affected, individual sites undergo progressive replacement of the bone tissue with abnormal tissue. As a result, the affected bones may not be as strong as normal. This condition is caused by a change in genetic information.
The affected bones may be painful. They may also become deformed or more fragile. If the leg bones are affected, you may have difficulty walking.
There may also be brownish patches on the skin. These patches are benign and do not normally cause any problems. The condition can also affect hormone production. This can have various effects, depending on the hormone. For example, if certain sex hormones are affected, puberty may start early.

- V: Tentative diagnosis
