Fibrous Dysplasia of bone is a relatively rare condition characterized by fibrous tissue replacement of skeleton. It may be monostotic (confined to one bone) or polyostotic (situated in many bones).
Here, six cases of fibrous dysplasia and, among them, typical three groups classified by Lichtenstein & Jaffe were experienced and treated during past one year.
Three cases were monostotic lesion, which is more common, and usually mild and asymptomatic. t
And another three cases. were polyostotic lesion, two of which were not associated with extraskeletal symptoms, and one case was associated with extraskeletal symptoms, so called "Albrights disease".
These six cases of fibrous dysplasia are reported with a review of the literatures.
