Vascular calcification in chronic renal failure and dialysis patients is well-documented and generally considered to be a consequence of decreased phosphorus excretion, secondary hyperparathyroidism, and increased calcium-phosphorus product. Following renal transplantation or parathyroidectomy, gradual resolution of metastatic calcification in the affected areas occurs. The case presented documents the consequence of secondary hyperparathyroidism with calcification of mammary vessels leading to severe breast pain with resolution of the pain and vessel calcification after renal transplantation.
