Abstract
Paraneoplastic vasculitis is a part of secondary vasculitis, the hematological neoplasm, such as lymphoma or myelodysplastic syndrome, which is most frequently observed. However, in multiple myeloma, cutaneous vasculitis is a rare complication, particularly as an initial clinical symptom. We report one case where a purplish reticulated patch on the lower extremity and an ear lobe skin necrotic change developed in a rheumatoid arthritis patient. He was diagnosed with multiple myeloma and cutaneous vasculitis.
