a. (Left) H&E. Higher power shot. Eosinophilic amorphous material separating myocytes with angulation of myocytes consistent with amyloidosis. b. (Right) Trichrome stain. Collagen around blood vessel (lower right corner) is blue, material surrounding myocytes is grey characteristic of amyloid. Interstitial material exhibited apple-green birefringence under polarized light with Congo red staining. (Not shown)
