Subcutaneous fat necrosis of the newborn is an uncommon disorder which is characterized by multiple erythematous subcutaneous nodules and plaques appearing in the first week to a month of life. The chief precipitating factors presumably concerned in this disease are obstetric trauma, anoxia and cold exposure. We observed a case of subcutaneous fat necrosis of the newborn in which intrauterine asphyxia and preeclampsia had occured.
