Liver haemochromatosis. Light micrograph of a section through the liver of a patient with haemochromatosis, a genetic disorder that leads to excessive amounts of iron (dark red) accumulating in body tissues. Tissues that can be affected include the liver, pancreas skin and brain. Excess iron in the liver can damage its cells causing scarring (cirrhosis) and ultimately liver failure. Treatment is with venesection, the regular removal of blood, which also removes some iron, making the body use stored iron to produce red blood cells. Stained with haematoxylin and eosin. Magnification: x140 when printed at 10 centimetres wide.
