Prior to his published case reports, these tumors were thought to be benign carcinomas, but Oberndorfer presented six patients with multifocal, pea-sized tumors of the ileum that appeared malignant on histologic examination.1 He named the disease “karzinoide” (carcinoma-like) to more accurately classify their clinical behavior. Today, the term “carcinoid tumor” provokes controversy among those who prefer more specific oncologic terminology for the disease, but it persists as an etymologic honorarium to the man who pioneered the field.2
