Abstract
|
|
|
|
Rapidly progressive glomerulonephritis (RPGN) is a clinical syndrome involving abrupt or insidious onset of hematuria, proteinuria, and anemia, and rapidly progressive renal failure. Crescentic glomerulonephritis is a histopathological term for RPGN showing extensive extracapillary proliferation, i.e., crescent formation. There are three major immunopathological categories of crescentic glomerulonephritis: anti-glomerular basement membrane (anti-GBM) antibody disease, immune complex-mediated, and pauci-immune (anti-neutrophil cytoplasmic autoantibody [ANCA]-positive). A small minority of all patients with glomerulonephritis develop crescentic glomerulonephritis. Anti-GBM antibodies and ANCA rarely coexist. There have been a few reports of dual positive crescentic glomerulonephritis with anti-GBM antibodies and ANCA in Korea. Here, we describe the case of a 73-year-old woman showing RPGN clinically and crescentic glomerulonephritis pathologically with coexisting anti-GBM antibodies and myeloperoxidase-ANCA.
