  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 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 (...)
