case_images: A renal biopsy revealed a pauci-immune necrotizing and crescentic glomerulonephritis (Figure 1) suggestive of MPO-ANCA-associated nephritis.
case_images: Photomicrographs from autopsy. (a) Liver (40x) with focal necrosis and microabscesses. (b) Liver (100x) with normal bile ducts without inflammation. Inset (400x): phagocytosis of blood cells by Kupffer cells. (c) Bone marrow (40x) displays appropriate cellularity for age with a slight reactive shift. Inset (400x): hemophagocytosis in the bone marrow. (d) Spleen (40x) with sinusoidal expansion by macrophages with abundant hemophagocytosis (inset: 400x).
