Fibrinous Inflammation

• Fibrinous exudation occurs in more severe endothelial injury.
  • Injury results in the escape of fibrinogen, which is converted to fibrin.
• The fibrin formed appears as a yellowish coagulation on the surface of or within a tissue.
  • Common in the lungs and on serous surfaces.
• In hollow organs the fluid may coagulate to form casts of the lumen.

• Fibrin will peel off from the underlying tissue without causing damage to it.
