If you look carefully you may be able to
find ongoing spotty necrosis. The arrow indicates an acidophilic

You may be puzzled to note that
many of the hepatocytes within the center of the regenerative
nodules are shrunken and more eosinophilic. These centrally located
hepatocytes have undergone ischemic necrosis. You will recall from
your syllabus that the fibrosis and regenerative nodules of
cirrhosis destroy the hepatic architecture and disrupt blood flow
through the liver. Often the hepatocytes at the center of the
regenerative nodules are only marginally supplied with blood. Should
the patient suffer a hypotensive episode, as typically occurs from
bleeding esophageal varices, the centers of the regenerative nodules
will infarct.

demarcation between the peripherally located, viable (V) hepatocytes
and the more centrally located, necrotic (N) hepatocytes. |
