Improved hypercalcemia after debulking of uremic tumoral calcinosis in a parathyroidectomized patient.

Abstract

Uremic Tumoral Calcinosis (UTC) is a rare complication of chronic kidney disease on dialysis, characterized by large periarticular calcification. Among some cases, hypercalcemia with no conventional etiologies has been reported. We present a case of UTC in which hypercalcemia occurred after parathyroidectomy and introduction of low-calcium containing dialysate. Work-up of hypercalcemia did not reveal any conventional etiology, but hypercalcemia resolved after debulking of the tumor. This change in serum calcium gives us an insight into the mechanism of hypercalcemia, occasionally seen among cases with UTC.
