Necrosis cutánea: un desafío para el médico

Skin necrosis must be considered as a syndrome, because it is a clinical manifestation of different diseases. An early diagnosis is very important to choose the appropriate treatment. Therefore, its causes should be suspected and confirmed quickly. We report eleven patients with skin necrosis seen at our Department, caused by different etiologies: Warfarin-induced skin necrosis, loxoscelism, diabetic microangiopathy, ecthyma gangrenosum, disseminated intravascular coagulation, necrotizing vasculitis, paraneoplastic extensive necrotizing vasculitis, livedoid vasculopathy, necrotizing fasciitis, necrosis secondary to the use of vasoactive drugs and necrosis secondary to the use of cocaine. We also report the results of our literature review on the subject.
