title: [Local cutaneous necrosis after injection of interferon beta].
abstract: BACKGROUND
  Skin necrosis at the site of interferon injections is unusual. With beta-interferon, it has been observed with high doses ranging from 90 to 180 millions daily.
  
  
  METHODS
  Is reported a case of abdominal skin necrosis following 6 months treatment with beta-interferon injections, 9 millions 3 times a week, in a 56 years-old man with chronic type C hepatitis. Histological analysis showed fibrin thrombosis of deep dermal vessels. There was no coagulation abnormality.
  
  
  CONCLUSIONS
  The mechanisms of the interferon induced skin necrosis are discussed.
