LV myocardium from the same patient shown in Figure 1, with findings consistent with a metabolic storage disease. A. Clusters of myocytes with vacuolated sarcoplasm (stained red) embedded in an area of scar (stained blue) x100. B. At lower power, similar area of myocardium shows subepicardial distribution of scarring and vacuolated myocytes x40. C. High power photomicrograph showing a large empty myocyte surrounded by smaller vesicles in an area of replacement fibrosis x40. D. Small focal scars (stained blue) surrounded by viable myocardium x40. All photomicrographs stained with Masson’s trichrome.
