Poor fiber structure

Fibrous structure is a benign tumor-like differentiation of fibrous bone tissue. Common bone lesions are unifocal. It often occurs during the rapid growth of adolescent bones, which can expand and develop throughout life. Multiple fibrous malformations are multiple lesions of adjacent bones. The most common sites are the proximal femur, tibia, humerus, ribs, and skull. Other bones also occur in the body. Lesions affect the strength of the bone, and repeated pathological fractures cause deformities. Multifocal fibrous structural defects with precocious puberty and Café-au-lait plaques are called Albright's syndrome.
