Coexistence of relapsing polychondritis and eosinophilic granulomatous with polyangiitis: A rare entity.

Relapsing polychondritis (RP) is a a rare multisystemic disease and it affects cartilaginous tissue and proteoglycan rich organs. The spectrum of clinical features are intermittent inflammation involving especially the auricular and nasal regions. In some patients with RP, systemic vasculitis, autoimmune diseases or malignancy may accompany. Although rare, any of the ANCA-associated vasculitis have been reported in patients with RP. Eosinophilic granulomatous with polyangiitis (EGPA) is a multisystem small vessel vasculitis associated with asthma and eosinophilia. Here we present a case of coexistence of RP and EGPA.
