A case of carcinoid tumour of the small intestine has been reported, which caused hormone producing multiple hepatic metastases. The 45 year old man had flush syndrome several times a day, that was caused by a carcinoid tumour originated from the jejunum. After the operation of the primary tumour he was treated by Sandostatin (Sandoz, Basel), which significantly reduced the symptoms and slowed down the progression. The neural elements containing substance P, neuropeptide Y, vasoactive intestinal polypeptide, serotonin, dopamine-beta-hydroxylase and somatostatin, which are thought to cause the symptoms, were investigated in the small intestine and the liver metastasis by an immunocytochemical method. It seems to be an interesting observation, that a large number of neuropeptide Y immunoreactive nerve fibers and some substance P and vasoactive intestinal polypeptide immunoreactive nerve processes and cell bodies were observed however, no trace of somatostatin and serotonin immunoreactive nerve elements could be detected in the hepatic metastasis. That can be a novel addition to the possible aetiology of the carcinoid syndrome and to the way how the somatostatin treatment acts.
