Cirrhosis of the liver:

Gross processing in autopsy

Template:Gross processing of the liver

Gross examination

Cirrhosis is characterized by pale areas. Categorize into either of the following: (1) micronodular, (2) macronodular, or (3) mixed:[1]

Micronodular cirrhosis, with diffuse areas of pallor.
  • Micronodular or diffuse cirrhosis (uniform nodules less than 3 mm in diameter).[notes 1]
  • 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.

Microscopic evaluation

Trichrome stain, showing cirrhosis as a nodular texture surrounded by fibrosis (wherein collagen is stained blue).

Components:[1]

  • 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.

Notes

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