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:
  • 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
