Description

<p>A case of Crohn's disease complicated with simultaneous double cancers of the small bowel is reported. The patient is a 66-year-old man who had suffered from Crohn's disease for 20 years. He underwent surgery to identify the source of repeated episodes of intestinal obstruction. Two short segments of strictures and proximal dilatations were found in the distal ileum. Therefore, we performed an en bloc resection of the two stenotic sections instead of strictureplasty. Histological examination of the resected specimen revealed not only Crohn's disease but also a well-differentiated adenocarcinoma within each of the two strictures. One had invaded to the muscular layer and the other to the subserosal layer. In cases of Crohn's disease with longstanding stenosis, the probability of carcinoma should be considered.</p>
