Warfarin-induced skin necrosis following heparin-induced thrombocytopenia.

Anticoagulants, such as heparin and warfarin, are commonly used in the treatment and prevention of thromboembolic events.

However, the risk of WISN may be increased with the initiation of warfarin in the setting of heparin-induced thrombocytopenia and thrombosis syndrome (HITT).
