Relapsing polychondritis (RP) is a rare multisystem autoimmune disease of unknown origin characterized by recurrent episodes of inflammation and progressive destruction of cartilaginous tissues.
Diagnostic Criteria for Relapsing Polychondritis (RP)
Three or more clinical signs must be present:
- Recurrent chondritis both auricles
- Non-erosive inflammatory polyarthritis
- Nasal chondritis
- Ocular inflammation
- Respiratory tract chondritis
- Cochlear and, or, vestibular dysfunction
OR 1 or more signs with histologic confirmation
OR Chondritis in 2 or more separate sites AND response to steroids or immunosuppression
