title: Case Report of Calciphylaxis Secondary to Calcium and Vitamin D3Supplementation.
abstract: BACKGROUND
  Calciphylaxis is a rare disorder that is very unusual outside the setting of end-stage kidney disease.
  
  
  METHODS
  A 64-year-old woman with normal renal function presented with painful leg ulcers. She had previously received 300 000 IU of vitamin D3followed by daily calcium and vitamin D3supplementation. A skin biopsy was consistent with calciphylaxis, and she was treated with sodium thiosulphate infusions and wound debridement.
  
  
  CONCLUSIONS
  Calcium and vitamin D3supplements are widely prescribed. We report a case of calciphylaxis triggered by calcium and vitamin D3supplementation in a patient with none of the typical risk factors. Our patient had an excellent response to treatment with sodium thiosulphate.
