Relapsing polychondritis (RP) is by no means an unknown disease, and already 30 years ago Michet et al1 had presented results from a single-center study of 112 patients with RP. In contrast to the earlier study,1 the study by Horvath et al2 published in Clinical Epidemiology allows some interesting revelations.
