Fibrous dysplasia is a mosaic disease that can involve any part or combination of the craniofacial, axillary and/or appendicular skeleton.[3] The type and severity of the complications therefore depend on the location and extent of the affected skeleton. The clinical spectrum is very broad, ranging from an isolated, asymptomatic monostotic lesion discovered incidentally, to severe disabling disease involving practically the entire skeleton and leading to loss of vision, hearing, and/or mobility.
