Abstract
Calciphylaxis is a rare and potentially fatal condition involving chronic, nonhealing wounds caused by microvascular calcification. There is currently no approved treatment for calciphylaxis, contributing to its devastating impacts on quality of life. In this case series, the authors highlight instances of potentially misdiagnosed calciphylaxis in a cohort of patients and emphasize the importance of accurate diagnosis through multidisciplinary management approaches.The authors report on three patients treated at a large tertiary academic center between March 2021 and March 2023. Consent was obtained from all patients, including for the use of patient images. The first and second patients, a 75-year-old man and 62-year-old woman, respectively, both underwent an extensive course of local wound care as well as sodium thiosulfate therapy. The third patient, a 61-year-old woman, was treated with a combination of medication adjustments, lymphedema therapy, pulse lavage treatment, and cadaveric skin substitute. Tissue biopsy was also obtained in two of the three subjects to aid in the diagnosis of calciphylaxis. Unfortunately, these procedures lead to diagnostic challenges and misadventures, highlighting the risks associated with biopsy of calciphylaxis.This case series demonstrates how correctly diagnosing calciphylaxis relies heavily on providers maintaining a high index of clinical suspicion based on patient history, presentation, and risk factors. The primary goals of treatment for calciphylaxis include appropriate wound care, management of infection and pain, and close monitoring.
