Definition / general

Diagnosis: incomplete cirrhosis (Ishak’s stage 5) vs. probable / definite cirrhosis (Ishak’s stage 6) (J Hepatol 1995;22:696)
Subclassification - micronodular ( < 3 mm) vs. macronodular ( ≥ 3 mm)
- Classically but not very clinically significant
- The former is more commonly associated with alcoholic liver disease, genetic hemochromatosis and Wilson disease, whereas the later is more frequently associated with viral hepatitis
- Micronodular cirrhosis and macronodular cirrhosis may be transformed in either way depending on disease activity (Arch Pathol Lab Med 2000;124:1599)
- Difficult to assess in liver biopsy specimen
Subclassification - Laennec fibrosis scoring system (J Hepatol 2011;55:1004)
- 4A - Mild cirrhosis; marked septation with rounded contours or visible nodules; most septa are thin (one broad spectum allowed)
- 4B - Moderate cirrhosis with at least two broad septa
- 4C - Severe cirrhosis with at least one very broad septum or many minute nodules
- Excellent interobserver agreement (kappa 0.83)
- Correlate with severity of portal hypertension, and Child-Pugh and MELD scores
Etiology
- Clinical, biochemical and serological correlation is essential
- Cryptogenic (idiopathic) cirrhosis accounts for 8 - 9% of liver transplants in the US; "burnt-out" NAFLD / NASH is a common cause of cryptogenic cirrhosis (Hepatology 2000;32:689)
