• hypertrophy
  3 June 2003

  Definition: Hypertrophy refers to an increase in the size of cells, resulting in an increase in the size of the organ.
  Pathogenesis
  The hypertrophied organ has no new cells, just larger cells. The increased size of the cells is due not to cellular swelling but to the synthesis of more structural components.
  Cells capable of division may respond to stress by undergoing both hyperplasia and hypertrophy, whereas in nondividing cells (e.g., myocardial fibers), hypertrophy occurs.

• Congestion
  19 December 2005

  Definition: Congestion is a passive process resulting from impaired outflow from a tissue. It may occur systemically, as in cardiac failure, or it may be local, resulting from an isolated venous obstruction. The tissue has a blue-red color (cyanosis), particularly as worsening congestion leads to accumulation of deoxygenated hemoglobin in the affected tissues.

• Ulcers
  18 March 2007

  Definition: An ulcer is a local defect, or excavation, of the surface of an organ or tissue that is produced by the sloughing (shedding) of inflammatory necrotic tissue. Ulcers can occur only when tissue necrosis and resultant inflammation exist on or near a surface.
  During the acute stage, there is intense polymorphonuclear infiltration and vascular dilation in the margins of the defect. With chronicity, the margins and base of the ulcer develop fibroblastic proliferation, scarring, and (...)
