Ischemic ulcers due to compromised microcirculation of the lower limbs cause painful ulcers that pose a challenge for the correct diagnosis and treatment. Livedoid vasculopathy, calciphylaxis, and Martorell's hypertensive ischemic ulcer are part of this group and present some similarities due to microvascular occlusive impairment. They are often misdiagnosed as inflammatory ulcers such as pyoderma gangrenosum and vasculitis.

Calciphylaxis is a rare and serious disorder characterized by vascular calcification and occlusion of the microvessels in the dermis, subcutaneous adipose tissue, visceral organs, and musculature. Studies have suggested that the major risk factors for developing calciphylaxis are chronic kidney disease and secondary hyperparathyroidism. Its diagnosis is clinical, and the treatment includes a multidisciplinary approach, although there are no clinical protocols based on randomized clinical trials.

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.

Calciphylaxis is a rare but potentially life-threatening disease that is not yet completely understood. It occurs mainly in patients with chronic kidney disease termed calcific uremic arteriolopathy (CUA) but also affects patients with normal renal function. Although this disease's pathogenesis is unclear, it is associated with the dysregulation of calcium and phosphate and subsequent calcification of peripheral arterioles.
