title: [Kasabach-Merritt syndrome of the leg associated with osteolysis or Gorham sign].
abstract: BACKGROUND
  Kasabach-Merritt syndrome and Gorham's sign are two uncommon and severe, sometimes life-threatening, complications in infants with vascular lesions. Their association has been described in rare cases.
  
  
  METHODS
  An infant with a vast congenital angiomatous lesion including an extensive lymphatic component, developed active regional osteolysis then suddenly suffered disseminated intravascular coagulation of the leg. Medical treatment was unsatisfactory. After unsuccessful use of low molecular weight heparin, pentoxifyllin and alpha interferon, amputation of the leg was required to avoid a fatal outcome.
  
  
  CONCLUSIONS
  Kasabach-Merritt syndrome does not develop on classic immature hemangiomas, despite some contradictory statements in the literature. In our case, a complex tumor developed in association with a lymphatic malformation. The association of Kasabach-Merritt syndrome with osteolysis (Gorham's sign) does not appear to be fortuitous. Therapeutic management of these severe complications is difficult and requires case by case analysis.
