• acute hepatitis
  30 May 2003

  Microscopy
  The essential components of the acute phase of hepatitis are:
  inflammatory-cell infiltration
  hepatocellular damage
  cholestasis
  Kupffer-cell activation
  endotheliitis
  bile-duct damage
  ductular reaction
  hepatocellular regeneration
  hepatocellular damage
  Hepatocellular damage range from minor degrees of cell swelling to cell death. They are accompanied by the inflammatory infiltration described below, reflecting the important role of cellular immunity in the (...)

• follicular gastritis
  11 November 2005

  Digital case
  HPC:311 : Follicular gastritis and active chronic gastritis, non-atrophical, Helicobacter pylori-associated
  Definition: Chronic gastritis in which there are large numbers of prominent lymphoid follicles in addition to the mononuclear infiltrate. Because H. pylori infection is also regularly present, it is considered the underlying cause of follicular gastritis.

• focal active colitis
  18 December 2003

  This inflammatory pattern is associated with bacterial (Campylobacter, Salmonella, Shigella, E. cati, Yersinia) and viral infections or drug-induced injury.
  Other clinical associations include irritable bowel syndrome and inflammatory bowel disease, particularly Crohn’s disease.
  In the absence clinical colitis, these changes often remain unexplained and could be related to bowel preparation.
