[Idiopathic cyclic edema in Klinefelter syndrome (author's transl)].

After a minor abdominal traumatism, M. B., 53 years of age, presents a sudden and acute edematous syndrome. Cardiac, renal, hepatic, nutritional and thyroid etiologies ares rapidly eliminated. A cavography and lymphography reveal the integrity of the drainage pathways. The idiopatic cyclic edematous syndrome is therefore evoked by few clinical details (diurnal weight gain, diurnal oliguria...). Exploration of the renin - angiotensin - aldosterone system, the Landis test and the marked radioactive serum albumin test attest to the exaggeration of capillary permeability. Likewise, it was discovered in this patient, a Klinefelter syndrome which was, until now, unknown. This case poses interesting pathogenic problems since the idiopathic cyclic edematous syndrome is a predominantly feminine disease. Only a few cases were described in the masculine sex and, to our knowledge, this syndrome has never been associated with Klinefelter syndrome.
