Relapsing polychondritis (RP) is a rare multisystem disorder. Myelodysplastic syndrome (MDS) with erythroid hypoplasia/aplasia is a rare form of myelodysplasia. Several cases of RP associated with MDS have recently been described. However, RP associated with MDS with erythroid hypoplasia/aplasia has never been reported. There was only one case report of polymyalgia rheumatica associated with MDS with erythroid hypoplasia/aplasia. In this study, we report a 79-year-old patient with RP, who developed MDS subtype refractory anemia (RA) with erythroid hypoplasia/aplasia, a very characteristic subtype of MDS.
