2. Fig 1
Light microscopy of a renal biopsy specimen shows (A) mild mesangial cell proliferation with lobular formation and thrombi in the glomerular capillary lumen and (B) foam cell infiltration and double contour, as well as glomerular thrombi. ([A] Azan stain, [B] periodic acid–methenamine silver stain; [A, B] original magnification ×400.)
