title: [Crohn disease in univitelline twins].
abstract: Authors report two homozygotic twins with Crohn's disease. Symptoms appeared at the ages of 11 and 13 and consisted mainly diarrhea accompanied by general signs of disease. Contrast X-Ray studies revealed in both ileo-cecal locations. In one of the patients there was an esophageal inflammation as well. In view of the obscure origin of Crohn's disease they consider interesting to report this familial observation in order to support genetic explanation.
