Tissue sampling
- Autopsy
- Liver biopsy. For a percutaneous liver biopsy, it is recommended to use a Birmingham gauge 16 or wider cutting needle, and obtaining a length of 20–25 mm of liver tissue. The presence of 10–12 portal tracts within the specimen is considered sufficient for reliable analysis, ensuring that architectural relationships between structures are maintained.[1]
Gross processing in autopsy
Make consecutive liver slices, such as in the sagittal or coronal plane.
Basic gross examination
- Inspect the color and texture of the surfaces, including external and cut surfaces. Potential pathologies:
-
Diffuse areas of pallor in cirrhosis, see Cirrhosis
-
Pale macronodules of cirrhosis, see Cirrhosis
-
Nutmeg texture of congestive hepatopathy
-
Liver metastases

- Look for any focal change in the liver volume, mainly any tumor.
- Determine liver weight.
Gross report
- Weight
- Color and texture of cut surfaces
- Any focal change
