[McCune Albright syndrome - diffuse orbital involvement due to fibrous dysplasia: a case report].

Fibrous dysplasia is a benign, slowly progressive bone disorder, in which normal bone is replaced by fibrous tissue. It is called McCune Albright syndrome when associated with skin hyperpigmentation and endocrinological disorders. We report a rare case of McCune Albright syndrome in a boy, who presented bilateral and diffuse involvement of orbits but few external craniofacial distortions.
