In autopsy, make consecutive liver slices, such as in the sagittal or coronal plane.
Cirrhosis is characterized by pale areas. Categorize into either of the following: (1) micronodular, (2) macronodular, or (3) mixed:
- Micronodular or diffuse cirrhosis (uniform nodules less than 3 mm in diameter).[notes 2]
- Macronodular cirrhosis (irregular nodules with a variation greater than 3 mm in diameter).
- Mixed cirrhosis (when features of both micronodular and macronodular cirrhosis are present): Usually micronodular cirrhosis progresses into macronodular cirrhosis over time.
- Diagnosing cirrhosis. The diagnosis of cirrhosis by biopsy requires the presence of fibrosis and nodules.
- Assessing the degree of inflammation (grade) and fibrosis (stage) of the disease.
No fibrosis, but mild zone 3 steatosis, in which collagen fibres (pink–red, arrow) are confined to portal tracts (P) (van Gieson's stain)
Histopathology of steatohepatitis with mild fibrosis in the form of fibrous expansion (van Gieson's stain)
Histopathology of steatohepatitis with moderate fibrosis, with thin fibrous bridges (van Gieson's stain)
Histopathology of steatohepatitis with established cirrhosis, with thick bands of fibrosis (van Gieson's stain)
Trichrome stain, showing cirrhosis as a nodular texture surrounded by fibrosis (wherein collagen is stained blue).

- Micronodular or diffuse cirrhosis can be due to alcohol, hemochromatosis, hepatic venous outflow obstruction, chronic biliary obstruction, jejunoileal bypass, and Indian childhood cirrhosis.
