Clinical findings
Fever, malaise, myalgia, weight loss, and autoimmunity, including antineutrophil cytoplasmic antibodies (p-ANCA). Skin lesions occur in 30 to 50%, usually presenting as purpura due to leukocytoclastic vasculitis, less commonly as nodules involving the vessels of the dermis and subcutaneous fat and ulcers. The kidney shows rapidly progressive focal and segmental glomerulonephritis.

DiffDx
