Abstract
Calciphylaxis, medically referred to as calcemic uremic arteriolopathy, stands as a rare and life-threatening dermatological condition that frequently emerges as a complication of chronic kidney disease (CKD), primarily affecting patients with end-stage renal disease (ESRD), who are typically undergoing dialysis. This condition is characterized by the development of cutaneous ischemic infarcts, originating from blood vessel obstructions within the subcutaneous fat and dermis. It is imperative to recognize that calciphylaxis is associated with an alarmingly high mortality rate, with more than 50% of afflicted individuals succumbing within a year, often due to complications like sepsis. Intriguingly, there have been relatively few documented instances of calcemic uremic arteriolopathy occurring in non-ESRD patients. In this paper, we undertake an extensive examination of calciphylaxis, delving into its pathophysiology, diverse clinical presentation, and the array of treatment modalities available. To illustrate these facets, we present a case report featuring a man afflicted with calciphylaxis in the setting of acute kidney injury (AKI), thus providing valuable insights into the atypical condition of this already rare disease. Given the scarcity of literature pertaining to calciphylaxis in patients with AKI, this case study aims to contribute valuable insight into potential factors underlying calcemic uremic arteriolopathy.
