Coexisting carcinoid tumor and Crohn's disease

Abstract

Several malignancies have been described occurring simultaneously with regional enteritis. Only four examples of coexistent carcinoid and Crohn's disease have been described worldwide. In this report, two new cases of simultaneous Crohn's disease and carcinoid tumor, diagnosed and treated within a single month, are presented. In one instance, a segment of terminal ileum contained regional enteritis, carcinoid tumor, and a small focus of adenocarcinoma.
