Painful cutaneous lesions, renal failure and urgent parathyroidectomy.

Abstract

We describe two patients with end stage renal failure who presented with painful skin lesions, which rapidly progressed to become necrotic and gangrenous. The diagnosis was calciphylaxis, a rare disorder due to calcification and luminal fibrosis of small and medium sized cutaneous and systemic vessels. Both patients had tertiary hyperparathyroidism. An urgent parathyroidectomy was performed on one patient, which relieved her symptoms; the other required local surgery but refused parathyroidectomy and died.
