Course Outline

  1. Types and Mechanisms of Cell Injury
  2. Reversible Parenchymal Changes
  3. Intracellular Water and Protein Accumulation
  4. Mesenchymal Mucoid Edema
  5. Fibrinoid Swelling

1. Types and Mechanisms of Cell Injury

★ Must-know

  • Cell injury may be reversible, irreversible, programmed, or residual, and its consequences include degeneration, cell death by necrosis, apoptosis, subcellular injury, intracellular accumulation of proteins, fats and carbohydrates, gangrene, and pathological calcification.

  • The principal mechanisms of cell injury are ischemia and hypoxia, free-radical injury, toxic injury, and immune-mediated injury.

Further detail

  • The listed mesenchymal changes are mucoid or chromotropic edema, fibrinoid swelling, hyalinosis, amyloidosis, mucinous changes, fatty infiltration, and extracellular pigment accumulation.

2. Reversible Parenchymal Changes

★ Must-know

  • Reversible parenchymal changes include intracellular accumulation of water, proteins, fats, carbohydrates, and pigments.

  • Intracellular water accumulation includes cell swelling, hydropic changes, and vacuolar changes.
