File:IPLab6Amyloid6.jpg|This is a low-power photomicrograph of liver tissue stained with Congo red (orange color in slide). Congo red reacts with amyloid and gives it an orange color (arrows).
File:IPLab6Amyloid7.jpg|This is a high-power view of liver tissue stained with Congo red. The orange amyloid material (arrows) is seen clearly between liver parenchymal cells.
File:IPLab6Amyloid8.jpg|This is a photomicrograph of Congo-red-stained liver tissue viewed with partially polarized light. Although not well demonstrated in this image, Congo-red-stained amyloid viewed through polarized light should give off a classic “apple green” birefringence (arrows). File:IPLab6Amyloid8b.jpg|The amyloid in this Congo-red-stained liver tissue demonstrates the classic “apple green” birefringence when viewed through polarized light.
File:IPLab6Amyloid9.jpg|This is a gross photograph of kidney from this case. Note the pale yellow material within the cortex (arrows). This is indicative of amyloid within the cortex and the glomeruli. Also note that there are multiple red spots in the cortex. These represent congested glomeruli due to the vascular compromise produced by the amyloid.
File:IPLab6Amyloid10.jpg|This photomicrograph of kidney demonstrates the amyloid deposits (arrows) within glomeruli.
