Light micrograph of fatty liver disease (steatosis) near the central vein (zone 3). This condition leads to the accumulation of triglyceride fats (seen as white spaces) in liver cells. The most common cause is heavy alcohol consumption, which disturbs normal fat metabolism. It can also be caused by toxins, diabetes and pregnancy. Steatosis is reversible by treating the underlying cause. This location of steatosis is more frequent in adult non-alcoholic fatty liver disease (NAFLD). The portal tract located in the bottom of the image shows inflammatory infiltrates and fibrosis. Stained with haematoxylin and eosin. Magnification: x90 when printed at 10 centimetres across.
