Comparison of acinar and lobular concepts of the microanatomical units of the liver. image The acinar concept explains better the pathophysiology of the liver. Cells in acinar zone 3, being the most remote from the vascular supply in the hilum of the acinus, are consequently the most vulnerable to injury. Death of liver cells in zone 3 results in the observed necrosis bridging between portal tracts and central veins in severe liver injury. image Lobular units are, however, often easier to perceive in histological sections.

Patterns of liver cell death and their clinicopathological significance. Death of the liver cells immediately surrounding central veins denotes cardiac failure, some other impediment to venous drainage, or some toxic cause (e.g. paracetamol overdose). Bridging necrosis (in acinar zone 3) is a feature of severe hepatitis. Interface hepatitis is death of liver cells at the margin of the portal tracts; this is a feature of chronic hepatitis due to a variety of causes. Apoptotic death of single cells is typical of acute viral hepatitis.
