Repeated occurrence of skin necrosis twice following coumarin intake and subsequently during decrease of vitamin K dependent coagulation factors associated with cholestasis.
A female patient is described who developed skin and subcutaneous fat necrosis on two occasions after intake of acenocoumarol. Several months later identical skin changes occurred during an episode of cholestasis associated with a prolongation of the prothrombin time to an extent comparable with therapeutic anticoagulation; intake of oral anticoagulants could be excluded. This association gives new insights in the pathogenetic mechanisms responsible for the so-called coumarin necrosis and indicates that it may be not due to drug toxicity or allergy.
