Familial occurrence of malignant carcinoid is rare (about 3%). Authors describe occurrence of the malignant carcinoid in two brothers. In the older one the diagnosis was estimated in 1991. He had multiple intestinal carcinoid tumor with multiple liver metastases histological type III by Soga classification. Patient is intermittently treated with somatostatin analogue--lanreotid and with interferon alfa. By this therapy the disease is stabile.
