[A rare clinical manifestation of intestinal carcinoid conditioning mesenteric vascular insufficiency (author's transl)]. / Una rara manifestazione clinica del carcinoide intestinale condizionante insufficienza vascolare mesenterica.

The Authors after having paid considerable attention on the contemporary existence of numerous carcinoid tumours of the intestine and of other abdominal organs, as well as on the frequent multicentricity exhibited by the very same at the level of the last tract of the ileum, explain this by considering the recent research performed on the APUD cells and on the cells of the diffuse endocrine system (DES) of the intestine. They present a carcinoid case, where it is understood that the product of secretion of the same, still not completely identified in its structure and mode of action, produces an arterial vascular alteration even at considerable distance from the tumour, hence bringing about an intestinal ischemic symptomatology which they hypothesize is the case for all the cells of the intestinal diffuse endocrine system, a type of self-regulatory feed-back hormonal system.
