Fetal hemorrhage from umbilical cord hemangioma.

Hemangiomas of the umbilical cord are rare. In this case, an acute, massive fetal hemorrhage from a ruptured umbilical hemangioma occurred after spontaneous rupture of membranes. Ectopic small intestinal mucosa covered the proximal surface of the umbilical cord. Fetal anomalies included a patent vitellointestinal duct remnant and distal ileal atresia. Fetal hemorrhage appears to be another previously unreported and potentially life-threatening complication of umbilical hemangiomas.
