An autopsy of a six-hour-old term neonate, who died during surgery for repair of a left diaphragmatic hernia, revealed an infantile hemangioendothelioma type I arising in a heterotopic lobe of liver in the left thorax. The upper pole of the tumor was attached by fibrovascular tissue to the lower lobe of the left hypoplastic lung. A pedicle attached to the lower pole of the heterotopic liver pierced through the diaphragm to the left lobe of the normal liver. This case is an example of an unusual association of congenital malformation and putative neoplasm.

Times of first stool passage were studied in 171 infants who weighed less than 1,500 g at birth. Delayed passage (greater than 48 hours) was noted in 20.4% of this group. Significant differences were noted between the delayed and nondelayed groups for gestational age, presence of severe respiratory distress syndrome, and the time of the first enteral feeding. In very low birth weight infants, delay in the passage of the first stool is a common occurrence. This delay is probably due to physiologic immaturity of the motor mechanisms of the gut, lack of triggering effect of enteral feeds on gut hormones, and the presence of severe respiratory distress syndrome, which may singly or in concert adversely affect gastrointestinal motility.
