Pathogenesis

Etiology

Predisposing factors

General
  • May develop after subcutaneous injection.
  • May develop <7 days following surgery.

Pathophysiology

  • Inflammation of subcutaneous fat.
  • Damage to fat cells releases lipid into extracellular space.
  • Lipid is converted to fatty acids and these are potent inducers of inflammation.
  • Granulomatous reactions to fatty acids develop.
  • Can be sterile or associated with infection.

Timecourse

  • Weeks.
