Penn Relapsing Polychondritis (RP) Program

The Penn Relapsing Polychondritis (RP) Center is a multidisciplinary program that provides comprehensive evaluation and treatment for patients with this highly complex and serious disease. We are one of the few academic centers in the world that both sees many patients with this rare disorder to provide outstanding personalized clinical care, and conducts research to advance our understanding of the disease and work towards developing better treatments. We have a unique research program that combines the strengths of the Vasculitis Clinical Research Consortium, the U.S. National Institutes of Health, and the Relapsing Polychondritis Foundation.

Patients seen at the Penn Relapsing Polychondritis Center will initially be evaluated by one of our expert Rheumatologists and, as necessary, subsequently referred to one of several other medical specialists with specific interests in this disease.
