[Calciphylaxis in chronic renal failure: 3 cases].

BACKGROUND: Calciphylaxis is a small vessel disease responsible for vascular calcification and skin necrosis. It occurs in association with chronic renal failure and has a poor prognosis. BUT: Report new cases. We report 3 cases of calciphylaxis occurred in patients with chronic renal failure secondary to interstitial nephritis in 1 case, diabetic nephropathy in 1 case and thrombotic microangiopathy in 1 case. CASES: They were 2 females an 1 man aged of 44, 3 years meanly. Hyperphosphoremia and hyperparathyroidism were the essential risk factors. All patients died by sepsis. This course was precipitating by corticotherapy in 2 cases. CONCLUSION: Early recognition and treatment of risk factors is mandatory to reduce mortality in uremic patients with calciphylaxis.
