[Craniofacial fibrous dysplasia: a case report].
Fibrous dysplasia is classified among benign bone tumors. It is a bone development anomaly characterized by hamartoma proliferation of fibrous tissue within the medullary bone, with secondary bony metaplasia, producing immature, newly formed and weakly calcified bone, without maturation of the osteoblast. It can be monostotic or polyostotic. The craniofacial localization occurs in 10%-25% of cases in monostotic forms and in 50% of cases in polyostotic forms. Fibrous dysplasia essentially affects children and young adults, with no sex preference. Its diagnosis is not always straightforward because the functional symptomology is often absent or not specific. Medical imagery is necessary and in difficult cases a bone biopsy. The major complication of the illness remains sarcomatous degeneration. Only symptomatic forms are treated. We report an observation of craniofacial fibrous dysplasia affecting a child and discovery of proptosis, with no other ocular or general functional signs.
