Coexistence of primary Crohn's disease and carcinoid tumor isolated to the appendix. A case report.

A patient is described in whom isolated Crohn's disease of the appendix was present simultaneously with isolated carcinoid tumor of the appendix. Appendectomy was the primary therapy and no recurrence of either disease has been discovered after four years of follow-up. We believe this to be the first case of its type to be reported. Crohn's disease of the appendix, carcinoid tumors of the appendix and the occurrence of gastrointestinal tumors in conjunction with Crohn's disease are all briefly discussed.
