Cirrhosis represents an “end-stage liver” - the final, irreversible result of diffuse hepatic disease, involving architectural disruption of the entire liver. Underlying chronic injury leads to loss of hepatic tissue with replacement [[Liver Fibrosis|fibrosis]]. Nodular regeneration occurs within regions of hepatic tissue in between fibrous tissue bands, giving rise to the characteristic multinodular gross appearance of this condition.

Overall, the liver is smaller than normal and firm to cut, firmness is due to the presence of fibrous tissue. It is pale, sometimes yellow in colour.

Cirrhosis is usually the end result of multiple pathological processes, in particular cell death and active inflammation with fibrosis. Regardless of the original underlying aetiology, however, the end-stage liver can no longer perform its functions, and is therefore associated with clinical manifestations of [[Liver Failure|hepatic failure]].

==Pathology==
  −
===Gross===
  −
The liver is smaller than normal and firm to cut, firmness is due to the presence of fibrous tissue. It is pale, sometimes yellow in colour and contains a regenerating nodule that can be small and even in size with the liver having a finely granular appearance, or much larger, uneven in size, and the liver surface is deeply fissured and irregular.

  −
===Microscopically===
  −
The liver exhibits all 3 responses to injury:
  −
*nodular regeneration of the parenchyma - haphazard regeneration of liver cells forming islands of new cells surrounded by condensed portal areas
  −
*fibrosis - early cases show areas of [[Liver Fibrosis|fibrosis]] connecting two or more portal triads, later cases have prominent laying down of cartilage.
  −
*biliary hyperplasia
