Cutaneous vasculitis as a presenting manifestation of acute myeloid leukemia.

One of the rare causes of secondary vasculitides is malignancy. Hematological malignancies produce secondary vasculitis more frequently than solid malignancies. Here in we report a case of acute myeloid leukemia presenting with anti-neutrophil cytoplasmic antibody-positive vasculitis. This case highlights the importance of looking for underlying malignancies, especially leukemias in patients presenting with features of systemic vasculitides.
