  • This is a low power photomicrograph of a section of liver. Even at this low magnification, areas of fibrosis can be appreciated.

  • This medium-power photomicrograph of liver shows an area of portal fibrosis and bile duct proliferation (arrows). Adjacent to this fibrotic portal region, hepatocytes are seen separated by dilated sinusoids. Throughout this section are found accumulations of yellow-brown bile pigment.

  • This high-power photomicrograph of fibrotic portal region demonstrates proliferation of the bile ducts (arrows).

  • This is a high-power photomicrograph of fibrotic portal region with several bile ducts that contain inspissated bile (arrows). Adjacent hepatocytes also contain bile pigments.

  • This is a medium-power photomicrograph of liver section stained with a trichrome stain to demonstrate the portal fibrosis. The fibrous connective tissue (collagen) stains blue.
