This is a gross photograph of liver (1) and pancreas (2) from this case of hemochromatosis. Note that both of these organs have a dark brown coloration.
-
This is a gross photograph of a cut section of liver from this case of hemochromatosis. Note that the liver is dark brown. Although hard to appreciate in a photograph, the tissue is also firm (cirrhotic).
-
This is a low-power micrograph of liver from this patient. Note the nodularity of the tissue (arrows).
-
This higher-power view of liver from this case demonstrates the nodules and the brown/black pigment within liver parenchymal cells (arrows).
-
This higher-power photomicrograph demonstrates the increased fibrosis in the periportal area (1) and the pigment accumulation (2).
-
This trichrome stain of liver section demonstrates the increased fibrous connective tissue in this liver. Note that the liver nodules (1) are surrounded by fibrous connective tissue (2).
-
This is a low-power view of liver section stained with Prussian blue. Prussian blue reacts with iron in the tissue to give a blue color.
-
This higher-power view of liver stained with Prussian blue demonstrates the marked accumulation of iron within the parenchymal cells (1) and in the Kupffer cells in the periportal area (2).
-
This is a gross picture of pancreas from this case. Note the brown discoloration of the tissue.
-
This is a histologic section of pancreas from this case. It is difficult to appreciate at this magnification, but there is brown pigment in the pancreatic acinar cells. Note the islets of Langerhans (1).
-
This is a histologic section of pancreas from this case stained for iron (Prussian blue). Note the accumulation of iron in the parenchymal cells (1). There is also iron in the pancreatic islets (2).
