title: Crohn's disease of the duodenum complicated by adenocarcinoma.
abstract: Patients with Crohn's disease of the small bowel or the colon are at risk for development of cancer within their chronically inflamed intestinal loops. We present here the first reported case of malignant degeneration of duodenal mucosa involved by Crohn's disease. The clinical observations as well as radiographic and endoscopic features of this unusual complication are described.
