ABSTRACT
Patients with end-stage renal disease often demonstrate retarded healing of surgical wounds, but the basis for spontaneous wound formation in these patients is less well understood. We report our experience with four patients with a unique clinical entity previously described as the uremic gangrene syndrome (also known as calciphylaxis) that involves spontaneously forming and insidiously progressive wounds of the skin and soft tissue in uremic patients with hyperparathyroidism. The importance of recognizing this phenomenon relates to the potential benefit to wound-healing efforts resulting from subtotal parathyroidectomy and adjustment of serum calcium and phosphate levels when severe hyperparathyroidism is present. Disrupted parathyroid homeostasis as a mechanism for soft-tissue ischemia and subsequent infarction is supported by wound biopsies demonstrating microarterial calcification. As experts in factors resulting in refractory wounds, plastic surgeons need be aware of this peculiar vulnerability for spontaneously forming wounds in uremic patients. Clinical and laboratory findings, success with wound treatment in four patients, and currently popular pathophysiologic mechanisms are discussed.
