Purple digit syndrome and warfarin-induced skin necrosis.
Warfarin is used extensively in clinical practice for numerous indications. It is generally safe. Bleeding is the major risk of warfarin; several uncommon adverse skin manifestations may also be associated with its use. These range from ecchymoses and purpura, haemorrhagic necrosis and maculopapular vesicular urticarial eruptions to cutaneous necrosis, purple digit syndrome and warfarin-induced skin necrosis. Early recognition and diagnosis of these adverse reactions are important to avoid morbidity and possible mortality. All health professionals should be aware of these complications.
