  This is a gross photograph of section of heart tissue from this case. The tissue was firm and had a waxy texture. If you use your imagination you can see pale yellow areas within this tissue which represent the amyloid deposits.

• 

  This is a low power photomicrograph of the heart tissue from this case. At this magnification the structure looks relatively normal.

• 

  This is a higher-power photomicrograph of the heart tissue from this case. Note the amyloid deposition throughout the myocardium (1) as well as deposition in the wall of the blood vessel (2).

• 

  This is a higher-power photomicrograph of extracellular amyloid (1) and deposition of amyloid in the vessel wall (2).

• 

  This is a special stain for amyloid (Luxol PAS) demonstrating the amyloid (1) and fibrosis (2) in the myocardium. The amyloid is darker purple/magenta and tends to be more amorphous. The fibrosis is pink and more fibrillar.
