title: Warfarin necrosis.
abstract: Skin and subcutaneous tissue necrosis is a rare complication of warfarin therapy. Although the incidence is low, with increased use of warfarin family physicians need to be aware of this potentially catastrophic event. This article reviews the history of warfarin necrosis and discusses its clinical presentation. The histologic findings with necrosed lesions are described, with emphasis on the possible pathogenesis of this disorder. Treatment options based on existing clinical experience as outlined in the literature are discussed.
