Overview

Cirrhosis occurs due to long term liver injury which causes an imbalance between matrix production and degradation. Early disruption of the normal hepatic matrix results in its replacement by scar tissue, which in turn has deleterious effects on cell function.

Pathophysiology

  • Cirrhosis is often preceded by hepatitis and fatty liver (steatosis). If the cause is removed at this stage, the changes are still fully reversible.
  • The pathological hallmark of cirrhosis is the development of scar tissue that replaces normal parenchyma, blocking the portal flow of blood through the organ and disturbing normal function. The development of fibrosis requires several months, or even years, of ongoing injury.
  • The fibrous tissue bands (septa) separate hepatocyte nodules, which eventually replace the entire liver architecture, leading to decreased blood flow throughout.
  • The spleen becomes congested, which leads to hypersplenism and increased sequestration of platelets.
  • Portal hypertension is responsible for the most severe complications of cirrhosis.

Genetics

  • Certain TERT (Telomerase reverese transcriptase)gene variants resulting in reduced telomerase activity has been found to be a risk factor for sporadic cirrhosis[6]
  • An uncharacterized nucleolar protein, NOL11, has a role in the pathogenesis of North American Indian childhood cirrhosis[7]
  • Loss of interaction between the C-terminus of Utp4/cirhin and other SSU processome proteins may cause North American Indian childhood cirrhosis[8]

Gross Pathology

Macroscopically, the liver may initially be enlarged, but with progression of the disease, it becomes smaller. Its surface is irregular, the consistency is firm, and the color is often yellow (if associates steatosis). Depending on the size of the nodules there are three macroscopic types: micronodular, macronodular and mixed cirrhosis.

  • In the micronodular form (Laennec's cirrhosis or portal cirrhosis) regenerating nodules are under 3 mm.
  • In macronodular cirrhosis (post-necrotic cirrhosis), the nodules are larger than 3 mm.
  • The mixed cirrhosis consists of a variety of nodules with different sizes.

Gross Pathology

Cirrhosis

On gross pathology there are two types of cirrhosis:

Macronodular cirrhosis[30]

Splenomegaly

On gross pathology, diffuse enlargement and congestion of the spleen are characteristic findings of splenomegaly.

Esophageal Varices

On gross pathology, prominent, congested, and tortoise veins in the lower parts of esophagus are characteristic findings of esophageal varices.

Microscopic Pathology

Microscopically, cirrhosis is characterized by regeneration nodules surrounded by fibrous septa. In these nodules, regenerating hepatocytes are disorderly disposed. Portal tracts, central veins and the radial pattern of hepatocytes are absent. Fibrous septa are important and may present inflammatory infiltrate (lymphocytes, macrophages). If it is a secondary biliary cirrhosis, biliary ducts are damaged, proliferated or distended - bile stasis. These dilated ducts contain inspissated bile which appears as bile casts or bile thrombi (brown-green, amorphous). Bile retention may be found also in the parenchyma, as the so called "bile lakes".[33]
