Because they originate from neuroendocrine cells, they are capable of secreting vasoactive substances, notably serotonin, kinin peptides, and histamine. If these substances reach the systemic circulation in sufficient quantity, they may produce the “carcinoid syndrome” which has important ramifications to the anesthesiologist.
