[Crohn's disease of small bowel manifested by obstructive carcinoma].

In ulcerative colitis the incidence of adenocarcinoma of the small bowel is higher than in the general population. More than 100 cases of carcinoma of the small bowel have been reported in patients with Crohn's disease of the same segment. However, obstructive carcinoma of the small bowel as the first manifestation of Crohn's disease has seldom been reported. We present such a case in which the first manifestation of otherwise silent Crohn's disease was intestinal obstruction by adenocarcinoma of the same segment.
