title: [Purpura following bithermotest in cryoglobulinemia].
abstract: Purpura is provoked when the affected area is warmed up to 40 degrees C by means of an infrared lamp in cryoglobulinemia after exposition to cold with consecutive urticaria. For this way of causing purpura in two steps, we suggest the designation "bithermo-test".
