[Cutaneous symptoms of carcinoid tumours of the small bowel (author's transl)].

Cutaneous symptoms of carcinoid tumours are classified in 4 groups: --Acute type: flusch and vasomotor signs (the caracters of which are described). --Chronic type: telangiectasia, hyperpigmentation, sclerodermia-like, cutaneous maetastasis. --Rare type with non-diagnostic sign. --Types in association with other dermatological conditions either unrelated disease or with a likely related disease such as phacomatosis. Dermatological diagnosis is generally easy as cutaneous symptoms is concomitant with metastatic tumours and increased levels of serotonin and 5-H.I.A. The carcinoid syndrom may take place in the concept of the tumours of the A.P.U.D. system on clinical, embryological, histological and biochemical basis.
