An early case of the Zollinger-Ellison syndrome produced by a carcinoid tumor of the duodenum.J Ark Med Soc. 1992 Aug; 89(3):124-5.JA
We have reported a case of Zollinger-Ellison Syndrome which proved to be due to a small carcinoid tumor of the wall of the duodenum. At the time that this was found, I could not find any such cases in the literature. In talking with Dr. Ellison personally, it was my impression that he was probably not aware of this syndrome. There are relatively few cases in the literature, and in a report by Dr. Van Heerden, et al from the Mayo Clinic, of 154 patients with carcinoid tumors of the GI tract, there were only two cases of the carcinoid tumor found the duodenum. One had a gastrin producing tumor 1 cm in diameter with positive nodes which was excised locally, and the patient was alive and well and not taking medication after 10 years. In this case, I think that serendipity played a great part, because I had no knowledge of the relation between the carcinoid tumor and the severe ulcer diathesis it produced.
