  • Warfarin is a widely used anticoagulant.
  • Skin and subcutaneous tissue necrosis is a rare but severe adverse effect of warfarin therapy.
  • Increased warfarin use necessitates physician awareness of this complication.

Purpose of the Study:

  • To review the history and clinical presentation of warfarin-induced skin necrosis.
  • To describe the histologic findings and discuss the pathogenesis.
  • To outline treatment options based on current literature.

Main Methods:

Main Results:

  • Warfarin-induced skin necrosis is characterized by specific clinical and histologic features.
  • The pathogenesis involves a paradoxical hypercoagulable state.
  • Treatment strategies vary but aim to manage the necrotic lesions and discontinue warfarin.

Conclusions:

  • Warfarin-induced skin necrosis, though rare, requires prompt recognition and management.
  • Understanding its pathogenesis is crucial for effective treatment.
  • Physicians should be vigilant for this complication in patients on warfarin therapy.
