Calciphylaxis of the Breast: A Case Report and Literature Review

Calciphylaxis, or calcific uremic arteriolopathy, is a rare but particularly morbid condition involving systemic medial calcification of arterioles causing ischemia and subsequent tissue necrosis. Although most commonly occurring over the abdomen and proximal extremities, calciphylaxis can present on nearly any skin surface with a tendency toward areas of increased adiposity. We report a case of a 53-year-old female with end-stage renal disease who presented with bilateral palpable breast masses and overlying skin changes. Diagnostic mammography and percutaneous biopsy of the lesion facilitated the diagnosis of calciphylaxis and she was treated with medical therapy, local wound care, and eventual tissue extirpation. Due to the morbidity attributed to calciphylaxis and associated wound complications, surgical extirpation is at times unavoidable. Once malignancy has been excluded, we recommend nonoperative management with prompt referral to Nephrology for medical optimization, reserving surgical debridement for nonhealing wounds and superinfection.
