Authors report a case in which relapsing polychondritis had been diagnosed two years before myelodysplastic syndrome developed and terminated in eosinophilic leukemia. The observation that relapsing polychondritis may precede myelodysplasia is not in concordance with some of the previous reports regarding relapsing polychondritis as a paraneoplastic phenomenon of myelodysplastic syndrome. The terminally developed eosinophilic leukemia is not supposed to be a blastic phase of the underlying myelodysplasia, much rather a second malignant process. This opinion may be confirmed by the early presence of blast cells in the myelodysplastic process without eosinophilia. It seems interesting to note that both our patient and his daughter suffered from diseases of autoimmune origin: acquired vitiligo and subacute cutan lupus erythematodes, respectively.
