case_images: Congo red staining highlighted mainly arteriolar and arterial amyloid deposits with few deposits in the mesangium (Figure 1A), and apple-green birefringence of these deposits was noted under polarized light (Figure 1B). The deposits stained strongly with anti-SAA antibody (Figure 1C) but not with anti-kappa and anti-lambda antiserum (not shown).
