title: Parathyroid carcinoma in a dialysis patient.
abstract: A 75-year-old woman who had been receiving dialysis for 3 years and had a long history of chronic renal failure attributable to reflux nephropathy was investigated for progressive hypercalcemia in the context of very high intact parathormone (iPTH) levels. Imaging showed two functional parathyroid glands in the neck. At parathyroidectomy, four variously enlarged parathyroid glands were found and completely resected, without autotransplantation. The histology of one of the glands showed invasive parathyroid carcinoma. Parathyroid carcinoma is a very rare condition, with only 16 previous cases involving dialysis patients described in the literature. We review the literature to draw together presentational and therapeutic information on the management of this problem in the setting of renal replacement therapy.
