Lobular Necrosis
H&E in this case of neonatal hemochromatosis shows lobular necrosis and collapse of the hepatocellular cords with residual hepatocytes and bile ductules.

Perl Iron Stain
Perl iron stain in this case of neonatal hemochromatosis shows marked iron deposition image within the hepatocytes.
