• 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 (...)

• salivary mucocele
  4 April 2005

  mucocele; labial mucocele
  Definition: Mucoceles and mucous retention cysts most often involve the minor salivary glands of the lower lip, buccal mucosa, and floor of the mouth.
  Mucoceles lack an epithelial lining and are therefore not true cysts.
  They are thought to result from ductal obstruction or trauma and represent accumulation and extravasation of mucus into adjacent tissues.
