Sternocostoclavicular hyperostosis (SCCH) presenting as a mass in the neck

We report three cases of sternocostoclavicular hyperostosis (SCCH), all of which presented as a solitary neck mass. This hypertrophic bone disorder has been well described in the Japanese literature, but is rarely encountered in North America. We discuss the clinical and pathological features of this disease, and review the world literature in order to bring this entity to the attention of the otolaryngologist, to whom it may present as a neck mass.
