Q. A 2-week old male neonate is brought to an emergency clinic established in a homeless shelter. He was delivered at the camp without any medical intervention. His mother reports that he has been fussy, refusing to feed, and has had multiple episodes of vomiting. Over the last 2 days, she noticed that he has been having bloody stools. On examination, the infant is lethargic, pale, and has multiple bruises and petechiae on his body. His abdomen is distended and there are signs of peritoneal irritation. Lab findings show prolonged PT and aPTT with normal bleeding time. What is the underlying pathophysiology leading to this presentation?
