Abstract:
Two cases of rapidly progressive glomerulonephritis (RPGN) with skin vasculitis-associated anti-neutrophil cytoplasmic antibody (ANCA) are examined. Both cases showed purpura on the lower legs on admission and subsequently revealed renal or pulmonary vasculitis. One case responded positively to oral prednisolone alone, but the other case showed high ANCA titer and renal—pulmonary vasculitis. We discuss the diversity of clinical symptoms and the titer of antibody-associated vasculitis.
