  Definition: Acute inflammation is a rapid response to an injurious agent that serves to deliver mediators of host defense-leukocytes and plasma proteins-to the site of injury.

  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. (...)

  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 (...)

• chronic inflammation
  1 June 2004

  Definition: Inflammation in which mononuclear leukocytes, including lymphocytes, plasma cells (plasmocytes), and macrophages (histiocytes) predominate.
  Occasional small lymphoid aggregates without germinal centers are to be expected, but presence of germinal centers is prima facie evidence of chronic inflammation.
  Prominent numbers of eosinophils and mast cells, and fibrocytes with fibrosis when there is tissue repair, are often included in the overall picture of chronic inflammation. (...)

• osteosclerosis
  12 December 2003

  Definition: An abnormal increase in the density of bone tissue.
  The condition occurs in a variety of disease states and is commonly associated with ischemia, chronic infection, and tumor formation.
  It also may be caused by faulty bone resorption as a result of some abnormality involving osteoclasts.
  Osteosclerosis is an increased bone density, visible on X-rays as an area of extreme whiteness. Localized osteosclerosis may be caused by a severe injury that compresses the bone, (...)
