title: Pauci-immune extracapillary glomerulonephritis and atheromatous embolization.
abstract: Renal atheroembolic disease presents several multisystemic signs and symptoms that may resemble the clinical signs of vasculitis. A few cases of renal atheroembolism associated with antineutrophil cytoplasmic antibodies (ANCA) have been described. We report the first case, to our knowledge, of a patient with cholesterol microemboli who also developed extracapillary glomerulonephritis in the presence of perinuclear ANCA (p-ANCA) with anti-myeloperoxidase ANCA. The patient had long-term follow-up of renal function after treatment with prednisone and cyclophosphamide.
