Skull Fibrous Dysplasia

Skull fibrous dysplasia is a disease in which fibrous tissue replaces bone and causes the skull to thicken and deform. Lesions can only affect the skull, but also bones in other parts of the body, such as the femur, tibia, spine, etc. The latter is also known as multiple osteoporosis. Very few of them are accompanied by tan pigmentation and precocious puberty, also known as McCune-Albright syndrome.
