Abstract
The development of immunological abnormalities in
various neoplasms is a rather common phenomenon.
The prevalence of life-threatening systemic vasculitis in
malignancy, however, is much lower. Nonetheless we
found an unexpected frequency of several autoimmune
manifestations, including systemic vasculitis, in certain
myelodysplastic syndromes. We illustrate this finding with the case of a 43-year-old man with signs of polyarteritis nodosa-like systemic vasculitis during progression of chronic myelomonocytic leukaemia.
Subsequently, we review the literature on the combination of myelodysplastic syndromes and systemic vasculitis and discuss the prognostic consequences, considerations for treatment and possible pathophysiological mechanisms.
