[Carcinoïd heart disease: clinical, light and electron microscopic study (author's transl)]

The authors report a clinical and pathological case of carcinoïd heart disease in a 70-years old man. The primary carcinoïd tumor was ileal with both hepatic and neighbouring lymph node metastases. The clinical history was dominated by a typical carcinoïd syndrom biologically confirmed and accompanied by a tricuspid insufficiency. An autopsy permitted to described with precision the topography and extent of the cardiac affection. The originality of this work is due to the ultrastructural study which has rarely been done. This study permitted us to make some clinical histopathological, histogenetic and pathogenetic comments.
