Polyostotic fibrous dysplasia is a rare bone disorder that occurs when abnormal tissue develops in one or multiple bones. This can result in pain, deformity, and increased risk of fractures. Some synonyms for this condition include Albright's disease, fibrous dysplasia of bone, and Jaffe-Lichtenstein syndrome. These terms are used interchangeably to describe this condition and each represents a different aspect of the disease. Albright's disease is named after Fuller Albright, a physician who described this condition in the early 20th century, while Jaffe-Lichtenstein syndrome is named after the physicians who first characterized the syndrome. Regardless of the name used, it is important for individuals with this condition to receive proper medical care and support.
