Light micrograph of a liver biopsy stained with Perls' Prussian blue method showing iron deposits (blue). In hereditary haemochromatosis the iron deposits are not homogeneous, leaving some iron-free areas (right and left border of image). In haemochromatosis, excessive iron is deposited in hepatocytes and characteristically concentrated in the cytoplasm around bile canaliculi.
