• cholestasis
  4 June 2003

  Definition: In morphological terms, cholestasis is the presence of visible bile in tissue sections. It is also known as bilirubinostasis because the main component seen by light microscopy is bilirubin.
  Bile is rarely seen in normal liver, and then only in minute amounts; cholestasis should therefore be regarded as pathological.
  The location of the bile varies. The commonest is in dilated bile canaliculi between hepatocytes. This canalicular form of cholestasis, sometimes called acute (...)

  HPC:311 : Follicular gastritis and active chronic gastritis, non-atrophical, Helicobacter pylori-associated
  HPC:328 : Lymphocytic gastritis
  Definition: Lymphocytic gastritis is a chronic gastritis characterized by lymphocytosis of foveolar and surface epithelium.
  Lymphocytic gastritis affects 0.83% to 4.5% of individuals,mainly middle-aged and elderly men.
  The disorder complicates various diseases, including celiac disease,
  helicobacter pylori infections, Crohn disease, (...)

  Definition: LIP is a form of ’idiopathic’ interstitial pneumonia.
  Lymphocytic interstitial pneumonia (LIP) is a lymphoproliferative disorder characterized by dense interstitial accumulation of lymphocytes and plasma cells.

• 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 (...)

• gastric mucosal atrophy
  7 March 2005

  Definition: Atrophy means wasting, with resulting reduction in size or amount of an organ, tissue, or cell type.
  Atrophy of the stomach affects primarily the glands, which become sparse and small. In atrophy of the gastric corpus and fundus, parietal and chief cells disappear from the oxyntic glands, and the residual glands may undergo pseudopyloric metaplasia.
  Mucosal atrophy can be noted grossly, especially in advanced, diffuse atrophy of oxyntic mucosa in the fundus and corpus where (...)

  Definition: Rheumatoid nodule is composed of a core of densely eosinophilic fibrin and necrobiosis surrounded by a chronic inflammatory infiltrate.
