Abstract
We witnessed anaphylactoid purpura associated with myelodysplastic syndrome in a 60 year-old male patient. The patient first felt general fatigue at June, 2001. He was pointed out anemia and abnormal hemocyte. As the result of a careful examination, the hematologist diagnosed him as myelodysplastic syndrome(MDS) at September, 2001. While his treatmet with oral steroids and transfusion, asymptomatic purpura appeared on his lower legs at November, 2001. The eruptions enlarged to his abdomen and arms. There were no abnormal findings on the platelet count and coagulation system. The histological examinations of his leg resulted in a diagnosis of anaphylactoid purpura. We discuss as skin eruptions associated with MDS, MDS presenting as anaphylactoid purpura, associations between anaphylactoid purpura and malignancy, vasculitis associated with malignancy.
