[Carcinoid of the duodenum in neurofibromatosis].

The authors described a very rare case of duodenal carcinoid in neurofibrimatosis in a 53-year-old patient who was treated by local excision of the tumour. In the discussion they draw attention to the possible development of carcinoid in neurofibromatosis as a manifestation of systemic affection of neuroectodermal tissues.
