We report an autopsy case of extremely immature newborn totally covered with fetal membrane. The infant was a female, 32 cm in length, 662 g in weight, accompanied with the intact umbilical cord and placenta. No remarkable pathological findings for disease or anomalies were observed. Floating tests of the lungs and gastro-intestinal tract were completely negative. In histological examination, the alveoli in the lungs were partially slightly open, filled with amniotic fluid. Pulmonary surfactant was negative immunohistochemically. No evidence was found to confirm a live-born. It was diagnosed that the immaturity has caused the delayed rupture of the fetal membrane and the death during the delivery.
