Light micrograph of a liver needle biopsy in an haemochromatosis showing brown iron deposits in the hepatocytes. Haemochromatosis is a genetic (autosomal recessive) iron disorder, which results in increased iron absorption from intestine and excess iron storage in several organs, mostly the liver. The excess iron storage causes liver injury and periportal fibrosis, leading, finally, to a micronodular pattern of cirrhosis.
