[Carcinoid tumors, carcinoid syndromes and related tumors (104 cases)]

One hundred and four consecutive cases of carcinoid among 194 APUD-omas (cerebral and gynecological tumours expected) are presented. Localization is as follows: bronchopulmonary (21%), duodenum (5,5%), small intestine (19%), Meckel's diverticulum (5,5%), appendix (39%), colorectal (5,5%), other (4,5%). Average age at diagnosis is very different for each localization of carcinoid tumour, as is prognosis: in our material, 33% of cases had an infiltrative tumour, 17% had lymph nodes metastases and 16% hepatic metastases. All 15 patients with carcinoidosis died but their survival varied considerably in length (from a few weeks to 21 years after the beginning of carcinoidosis). In addition, 3 patients presented with the Zollinger-Ellison syndrome, 2 of them having an atypical or probable form of the MEN I syndrome.
