What is leontiasis ossea?
HYPEROSTOSIS cranii, craniosclerosis, or leontiasis ossea is a rare disease found most often in individuals in the early decades of life. It produces enormous, diffuse hyperostoses, beginning usually in the bones of the face and extending to those of the skull. The term leontiasis ossea was given by Virchow (12).

What is Monostotic fibrous dysplasia?
Monostotic fibrous dysplasia is a form of fibrous dysplasia where only one bone is involved. It comprises a majority of the cases of fibrous dysplasia (approximately 70–80%).
What is craniofacial fibrous dysplasia?
Craniofacial fibrous dysplasia is a bone disease of the face and skull that replaces normal bone with fibrous-type tissue. This tissue is not as hard as normal bone, and because it is soft and stringy, it makes the bone more fragile and prone to break.
What happens in Paget’s disease?
Paget’s (PAJ-its) disease of bone interferes with your body’s normal recycling process, in which new bone tissue gradually replaces old bone tissue. Over time, bones can become fragile and misshapen. The pelvis, skull, spine and legs are most commonly affected.

What is the difference between Monostotic and polyostotic fibrous dysplasia?
Two forms of FD exist, a monostotic and polyostotic form. Polyostotic disease tends to present at a younger age involving more than 1 bony area, whereas monostotic disease may remain nascent only manifesting itself radiologically, leading to the diagnosis of fibrous dysplasia.
Is fibrous dysplasia progressive?
Fibrous dysplasia is a chronic disorder and is often progressive. Although the lesions may stabilize and stop growing, they do not disappear. Individual lesions may progress more rapidly in the polyostotic form of the condition and in growing children.
