Answer

The hallmark of acute hepatitis B is liver cell death. Scattered within the lobule are small, individual clusters of dying hepatocytes in apoptosis. (When the nucleus is extruded, it is an eosinophilic, or Councilman, body). Many of the surviving hepatocytes show hydropic swelling known as ballooning degeneration. Lymphocytes diffusely infiltrate the lobule, with macrophages and neutrophils seen occasionally.
