AbstractCalciphylaxis is a rare condition of induced systemic hypersensitivity in which tissues respond to appropriate challenging agents with a sudden local calcification. It is characterized by acute calcium deposition in the medial layer of small and intermediate dermal vasculature that can lead to epidermal ischemia, ulceration, and necrosis. Calciphylaxis typically occurs in patients with end-stage renal disease who are undergoing dialysis and who have secondary hyperparathyroidism. Even in this population the incidence is less than 1%. The cause of calciphylaxis is unknown. However, it has been suggested that deficiencies of protein C and protein S may play a role in the pathophysiology of this disorder. Our patient is the fourth with cirrhosis to be reported to have developed calciphylaxis and adds further evidence that low levels of these anticoagulant factors may be an important etiologic factor for development of calciphylaxis. This report should alert the clinician that calciphylaxis occurs in patients with cirrhosis and should stimulate further research concerning the possible role of protein C and protein S deficiency in calciphylaxis.
