There have been few documents for histopathological examination on congenital esophageal atresia. Recent increasing number of reports in which there is coexistence of congenital esophageal stenosis due to tracheobronchial remnants and esophageal atresia has led to the histopathological study of the anomaly. The specimens from 6 babies not operated upon were studied. Microscopic examination showed seromucous glands, resembling tracheo-bronchial glands, in the muscle coat of the fistula in five of the six specimens examined. In three of the specimens, fragments of cartilage were identified. The transition from the fistula to normal esophagus occured at a variable distance from the tracheo-bronchial end - from 1 to 24mm.
