[Hormonally active pancreatic tumors (apudomas). A review]

Hormonally active pancreas tumours have ceased to be rare cases, and by means of up-to-date methods they are now more frequently diagnosed than they used to be in the past. An account, based on the authors' own experience, is given in this paper of diagnostic and surgical problems relating to the various hormone-producing tumours of the pancreas. Particular reference is made to the treatment of malignant apudomata and to new concepts which have resulted from the introduction of H2 receptor blockers.
