This is the first case report of 18 trisomy syndrome in Korea. Case 1： A 2. 3kg weight premature female infant have born at 36 weeks of gestation at Severane Hospital. No specific history was obtainable except polyhydramnios in antenatal period. On physical examination soon after birth shows small eyes, low set ears, micrognathia, short sternum, bilaterally abducted index fingers flexed upon the third fingers with poor Moro reflex, Polydactylism have been found by hand bone X-ray. The infant had expired at 47 hours after birth due to respiratory failure. On autopsy interventricular septal defect, diaphragmatic hernia, and Meckefs diverticulum had been found. Case 2: six weeks old female infant admitted to Severance Hospital due to respiratory difficulty and perioral cyanosis. The mother had experienced several spontaneous abortions and family history rev- ealed hermaphroditism in one uncle. Physical examination shows small eyes, micrognathia, low set ears, tshort sternum, grade BI / V systolic murmur at apex and abducted index fingers flexed upon the third fingers bilaterally.
