Ground glass hepatocytes. H&E stain. (WC)

The ground glass hepatocyte, abbreviated GGH, is a histologic finding that is seen in medical liver pathology and usually suggest a chronic hepatitis B infection.

General

  • Usually suggests chronic HBV infection.
    • Pattern NOT seen in acute HBV.
    • Caused by virion particles.

Classification

  • GGHs are not routinely classified.

Notes:

  • Several different types of GGHs are recognized.[1]

Classification:[2]

  • Type I ground glass hepatocytes (GGHs).
    • Weak Pre-S2 positive immunostaining; morphology: GGHs scattered singly.
  • Type II GGHs.
    • Pre-S2 negative immunostaining; morphology: GGHs in clusters.

There is some suggestion that type II GGHs predispose to HCC, based on data in children[3] and based on an animal model.[4]

Microscopic

Features:

  • Eosinophilic dull/hazy, somewhat irregular cytoplasm.
    • Ground glass[5] = glass with a rough/flat finish; glass that is translucent and has a matte finish.
      • The term is frequently used in radiology to describe hazy radiodense areas in the lung.[6]

DDx:

  • Pseudo-Lafora bodies in patients on disulfiram (anatabuse) - rare.
