Cirrhosis of the liver:

Gross processing

In autopsy, make consecutive liver slices, such as in the sagittal or coronal plane.

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 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.

Microscopic evaluation

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.
