  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 (...)

• lymphoepithelial sialadenitis
  5 November 2007

  LESA, myoepithelial sialadenitis, MESA, salivary benign lymphoepithelial lesion,
  Definition: LESA is found in virtually all patients with Sjögren’s syndrome but may occur without Sjogren’s syndrome. It is associated with lymphoid infiltration of salivary gland tissue, producing atrophy and destruction of the acini.
  Myoepithelial sialadenitis of the salivary gland is associated with an increased risk of lymphoma, but criteria that predict its development have not been clearly defined. (...)
