• 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.

• caseous necrosis
  16 September 2005

  Caseous necrosis is a distinctive form of coagulative necrosis, is encountered most often in foci of tuberculous infection.
  The term caseous is derived from the cheesy white gross appearance of the area of necrosis.
  On microscopic examination, the necrotic focus appears as amorphous granular debris seemingly composed of fragmented, coagulated cells and amorphous granular debris enclosed within a distinctive inflammatory border known as a granulomatous reaction. Unlike coagulative (...)

  polyp. Adj. polypous, polypoid WKP
  Definition: A polyp is an abnormal growth of tissue projecting from a mucous membrane.
  If it is attached to the surface by a narrow elongated stalk, it is said to be pedunculated. If no stalk is present, it is said to be sessile.
  Polyps are commonly found in the colon, stomach, nose, ear, sinus(es), urinary bladder, and uterus.
  They may also occur elsewhere in the body where mucous membranes exist like the cervix, vocal folds, and small intestine. (...)

• 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.

  cutaneous congestion
  cerebral congestion
  visceral congestion
  renal congestion
