title: Sternocostoclavicular hyperostosis: rheumatologic, radiologic, and dermatologic characteristics.
abstract: Two recently observed patients with sternocostoclavicular hyperostosis exemplify the characteristic presentation of this rheumatologic disorder. We describe its manifestations, review the literature on this subject, and discuss clinical and radiologic aspects, including the frequently associated dermatologic disorder palmoplantar pustulosis. Sternocostoclavicular hyperostosis is an increasingly common diagnosis, and practicing physicians should be aware of the distinctive features that allow accurate differentiation from psoriatic arthritis and other diseases.
