Which of the following statements about monostotic fibrous dysplasia is correct?

Monostotic fibrous dysplasia is characterized by the involvement of only a single bone, which is precisely why the correct choice in this scenario is that it involves just one bone. This condition is a type of fibrous dysplasia where abnormal fibrous tissue replaces normal bone, and it can occur in various bones throughout the body. However, when it is classified as "monostotic," it indicates that it affects one specific bone, distinguishing it from polyostotic fibrous dysplasia, which involves multiple bones.

This condition can manifest in various bones, including the ribs, femur, and craniofacial bones. While it may lead to localized pain or discomfort depending on the area and extent of involvement, significant pain is not a guaranteed feature, and it may vary among individuals. Additionally, it can affect any bone in the body, and it is not restricted to the mandible. Therefore, recognizing that monostotic fibrous dysplasia pertains strictly to a single bone is crucial for understanding the nature and diagnosis of this condition.
