Calciphylaxis: Beating the Odds.

Calciphylaxis is an obliterative vasculopathy characterized by ischemic cutaneous necrosis secondary to the calcification of small- and medium-caliber blood vessels. This condition poses a significant therapeutic challenge and is often associated with poor outcomes. We report the case of a 59-year-old man who had been on renal replacement therapy for 28 years and presented with a painful necrotic ulcer on his left leg, which progressively worsened over three weeks. A skin biopsy confirmed the diagnosis of calciphylaxis. The treatment approach included intensified hemodialysis, optimization of mineral and bone disorder management, treatment of secondary bacterial infection, intravenous sodium thiosulfate infusion, chemical and surgical debridement, and partial-thickness skin grafting. This comprehensive strategy resulted in complete wound healing within three months. This case highlights the importance of early diagnosis and a multidisciplinary approach in managing calciphylaxis, a rare condition associated with a highly unfavorable prognosis.
