Massive thymic hemorrhage in a neonate: an entity revisited

The authors describe a case of early neonatal death of a full-term infant who had respiratory distress and anemia after fetal distress during labor. Postmortem examination disclosed mediastinal compression by a large fresh hemorrhage into the left lobe of the thymus. Massive thymic hemorrhage is an extremely rare but sometimes lethal occurrence; it may represent a manifestation of early-onset hemorrhagic disease of the newborn.
