Relapsing polychondritis and myelodysplasia: a report of two cases and review of the current literature.

Relapsing polychondritis (RP) is a rare multisystem disorder. We describe two case reports of patients with RP, one of whom developed myelodysplasia subtype refractory anaemia (RA) and the other, refractory anaemia with ringed sideroblasts (RARS). We also review the literature of association between RP and haematological disorders.
