[Familial reno-vascular hypertension (author's transl)].

The authors report a case of hypertension due to dysplasia of the renal arteries in a young man, and found the same disease in siblings. Two sisters and one brother also had renal hypertension, whereas the other relatives were unaffected. Two similar cases found in the world literature, did not permit the authors to determine the cause of this disease. This case is reported in order to stimulate research and the discovery of new cases.
