title: The coexistence of carcinoid tumor and Crohn's disease.
abstract: We report what we take to be the ninth case of an intestinal carcinoid tumor coexisting with Crohn's disease; we believe that it is also the first case of Crohn's disease in which the carcinoid tumor involved both the small and large bowel, as well as the appendix. The two lesions may be remarkably similar in their clinical presentation, gross appearances, and radiologic features. We suggest that the actual incidence of their coexistence may be greater than the few reports suggest.
