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 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

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.
  • Finding the most probable differential diagnoses that cause the cirrhosis (or correlating with a previously established diagnosis).
Correlate by information in the referral/requisition form, and preferably look in medical records as well.

Example report

  • Histologic features consistent with liver cirrhosis.
  • See comment.
Comment

Sections show core needle biopsy of liver parenchyma with distortion of the normal lobular architecture. There is prominent periportal fibrosis and bridging fibrosis with secondary formation of small regenerative nodules as highlighted by trichrome stain. The portal triads demonstrate chronic inflammatory cell infiltration mainly composed of lymphocytes. Spillage of lymphocytes beyond the limiting plate is also noted, focally. Iron stain demonstrates no increased iron deposits within hepatocytes. There is no histologic evidence of neoplastic disease. The histologic changes in this biopsy are consistent with the established micronodular liver cirrhosis,, consistent with clinically known alcoholic liver cirrhosis. Clinical correlation is advised.

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.
