Congestion
19 December 2005Definition: 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.

hypertrophy
3 June 2003Definition: 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 2005Caseous 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 (...)
