Introduction: Calciphylaxis is a condition which involves ectopic deposition of calcium in arterioles of various organ systems. Here, we present a rare case of mammographic calcifications in a patient on long-standing renal dialysis.
Case: This is a 57-year-old female who presented to breast clinic with unilateral severe pain and lumpiness of her breast. On mammography, calcifications were identified which were associated with focal lesions on ultrasound. An image-guided core biopsy showed numerous foci of histological calcification within a large area of fat necrosis. The location within arterioles was confirmed by CD31 immunohistochemistry. The diagnosis of fat necrosis with benign calcifications due to mammary calciphylaxis was made.
Conclusion: The hallmark of calciphylaxis is the deposition of calcium within small- to medium-sized vessel walls. This leads to ischaemia and necrosis of tissue. In the breast, only a few cases were reported in which patients presented with a necrotic lesion resembling carcinoma. These are reviewed in this report.

Article Synopsis
- Calciphylaxis is a rare and severe condition that causes blood vessel calcification, leading to tissue death, often appearing in areas with more body fat like the abdomen and breasts.
- An elderly woman with end-stage kidney disease experienced severe breast pain and nodules, leading to a diagnosis of calciphylaxis through clinical assessments and imaging.
- After standard treatments failed, glucocorticoids were used effectively, showing significant improvement, but she experienced a relapse after three months, requiring treatment again.

Aluminium, the third most abundant element in the earth's crust, was long considered virtually innocuous to humans but has gained importance in the recent past. Aluminium is ubiquitous in the environment, with various sources of exposure like cosmetics, the food industry, occupational industries, the medical field, transport and electronics. Aluminium finds its utility in various aspects of dermatology as an effective haemostatic agent, anti-perspirant and astringent.

Calciphylaxis is a rare condition characterised by painful necroses due to microvascular calcifications. It primarily affects individuals with end-stage renal disease and affected calcium-phosphate metabolism. This is a case report of a 55-year-old woman with end-stage renal disease who developed a necrotic ulcer at the breast due to calciphylaxis.

Calciphylaxis, also called calcific uremic arteriolopathy, is a rare benign cutaneous manifestation. Although little is known about its pathogenesis, it is thought to be a result of vascular wall calcification leading to soft tissue necrosis, and it is usually encountered in patients with end-stage kidney disease (ESKD) on long-term renal dialysis. Breast calciphylaxis is a rare entity that may present as a breast mass or necrotic ulcers, and it is common for it to be initially mistaken for a malignant breast pathology.

Introduction: Calcific uremic arteriolopathy is a life-threatening cutaneous condition in patients with chronic kidney disease. Often, clinical diagnosis is accompanied by histopathologic evaluations demonstrating vascular calcium deposits. We aimed to investigate the presence of cutaneous calcifications in non-lesional tissue in patients with chronic kidney disease, and the relation to systemic vascular calcification.
