Conn and Seltzer3 in 1955 presented an excellent review and etiologic classification of spontaneous hypoglycemia—organic and functional. Our report presents an additional interesting case of functioning islet-cell adenoma and emphasizes some important clinical and technical points in the surgery of this tumor.

The patient was a 29-year-old white housewife admitted to the Albert Einstein Medical Center, Southern Division, on July 25, 1958, complaining of "fainting spells" three months prior to admission. The first "attack" preceded breakfast after arising,
