In 1927, Dr. William J. Mayo1 discovered the first functioning metatastic islet-cell carcinoma, and one year later Roscoe Graham2 removed the first benign functioning adenoma. Since that time between 400 and 500 case reports of islet-cell tumors have appeared in the literature. By 1950, Howard, Moss, and Quarrie3 had collected 398 cases, and, by 1952, Whipple4 reported a personal collection of 34 patients. For the average surgeon, however, this entity will remain a rarity, particularly the malignant tumor, as only about 10% of islet-cell tumors are frankly malignant and about half of these will have functioning metatastases.
The control of the hypoglycemia in such situations not amenable to surgery presents a challenge to the surgeon. We wish herewith to report our experience with one such patient.
