title: [An unusual late manifestation of hemorrhage caused by vitamin K deficiency].
abstract: After an uneventful pregnancy and birth at home without vitamin K-prophylaxis, a 13-day-old breast-fed newborn showed an unexplained swelling of his right elbow and avoided movement of his right arm. One week later a swelling of his left thigh and hip with extensive hematoma led to the diagnosis of vitamin K-deficiency. The initial symptoms can be interpreted as an unusual primary manifestation of late hemorrhagic disease caused by vitamin K-deficiency.
