[Systemic calciphylaxis and acquired perforating disease in a uremic patient].

Abstract

We show the case of a patient suffering from a chronic renal failure in hemodialysis. He had a ischemic necrosis that was quickly progressive in his fingers and toes. It was necessary to amputate them. Diffuse vascular calcifications were recorded so radiologically than pathologically. PTH and phosphocalcic product were raised. Parathyroidectomy was practised with a quick initial improvement but immediately new distal ischemic lesions and keratotic papules with histologic perforation, that became necrosed, appeared in his buttocks and inferior extremities. The coexistence of acquired perforating disease and calciphylaxis in uremic patients has not been reported until now.
