An unusual case of craniofacial fibrous dysplasia presenting in early infancy

Fibrous dysplasia (FD) of bone is one of the most frequently encountered anomalies of skeletal development. It may involve one or more bones and, particularly when polyostotic, is sometimes associated with abnormal skin pigmentation and endocrine abnormalities. FD occurs mainly in large limb bones, ribs, and craniofacial bones in older children and young adults. Usually craniofacial involvement is detected because of local swelling or asymmetry of the face or head. Neurological symptoms, primarily due to involvement of the foramina, have been reported but are not common. Infantile fibrous dysplasia of the craniofacial region has rarely been reported.
