Intestinal tumour arising from specialized cells with paracrine functions (APUD cells), also known as argentaffinoma. The primary tumour is commonly in the appendix, where it is clinically benign; hepatic secondaries may release large amounts of vasoactive amines such as serotonin to the systemic circulation.
