Infantile cortical hyperostosis associated with the Wiskott-Aldrich syndrome.

A case report of an infant with the Wiskott-Aldrich syndrome and clinical and radiological features of infantile cortical hyperostosis (Caffey disease) is presented. This is the third case described of the association of these two rare disorders and gives further support to the role of an immunologic defect in the pathogenesis of infantile cortical hyperostosis.
