In 1898 Bryant and White reported features of the condition that was later described as calciphylaxis by Selye in 1961 because of a pathophysiologic resemblance to anaphylaxis [1,2]. Calciphylaxis (or calcific uraemic arteriolopathy) is characterized by medial calcification of small arterioles, intimal proliferation, fibrosis and thrombosis resulting in ischaemia, necrosis and superinfection of the skin and subcutis. When renal function is normal, calciphylaxis has been reported infrequently, associated with conditions such as primary hyperparathyroidism [3]. However, amongst patients with chronic kidney disease (CKD) on dialysis, the annual incidence has been estimated at 1–4%, with an apparent increase over the past decades that may reflect the increased use of calcium-based phosphate binders [4,5]. For patients on dialysis, mortality rates are increased 8-fold if calciphylaxis develops [6]. The mortality of non-ulcerating types is
