[Sclerodermic renal crisis: case report].

Sclerodermic renal crisis is defined as a severe arterial hypertension or rapidly progressive glomerulonephritis in a sclerodermic patient, associated with anuria due to no other cause but systemic sclerodermia. It constitutes a rare and dangerous complication. The renal prognosis can be effectively improved by converting enzyme inhibitors, allowing a better arterial hypertension control. However, the associated mortality remains high, a follow up must be instaured in order to prevent the apparition of renal lesions in all sclerodermic patients. We report a case of rapidly progressive renal failure with hypertension in a patient with no previous problems, which preceded the development of scleroderma diffuse cutaneous form. The biopsy showed a microangiopathy in the context of scleroderma renal crisis. The evolution was marked by the presence of chronic renal insufficiency which necessitated the dialysing start.
