Acral gangrene as a presentation of non-uremic calciphylaxis

Abstract

We are describing a case of 55-year-old obese female with significant history of uncontrolled rheumatoid arthritis, who recently had decreased her immune-suppression medications. She presented with extensive acral gangrene involving multiple fingers and toes. Clinical picture and laboratory findings were suggestive of vasculitis; however, skin biopsy established diagnosis of calciphylaxis, in settings of normal kidney function. Patient was treated with sodium thiosulfate with gradual improvement in her skin lesions.
