*Eosinophilic dull/hazy, somewhat irregular cytoplasm.
{{Main|Ground glass hepatocyte}}
**Ground glass<ref>URL: [http://en.wikipedia.org/wiki/Ground_glass http://en.wikipedia.org/wiki/Ground_glass]. Accessed on: 7 June 2010.</ref> = 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.<ref>URL: [http://www.healthsystem.virginia.edu/internet/radiology/educ/groundglass.cfm http://www.healthsystem.virginia.edu/internet/radiology/educ/groundglass.cfm]. Accessed on: 7 June 2010.</ref>
*Usually suggests '''chronic''' [[HBV]] infection.
**Pattern NOT seen in acute HBV.
**Caused by virion particles.
 
DDx:
*Pseudo-Lafora bodies in patients on disulfiram (anatabuse) - rare.
 
====Classification====
*GGHs are not routinely classified.
 
Notes:
*Several different types of GGHs are recognized.<ref name=pmid14633616>Wang HC, Wu HC, Chen CF, Fausto N, Lei HY, Su IJ. Different types of ground glass hepatocytes in chronic hepatitis B virus infection contain specific pre-S mutants that may induce endoplasmic reticulum stress. Am J Pathol. 2003 Dec;163(6):2441-9.

*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<ref name=pmid19719772>Pre-S2 deletion mutants of hepatitis B virus could have an important role in hepatocarcinogenesis in Asian children.
