title: Complete resolution of tumoral calcinosis after renal transplantation.
abstract: A 41-year-old male receiving hemodialysis for 10 years was referred to our hospital for multiple masses progressively growing in multiple joints and buttocks, which were diagnosed as giant tumoral calcinosis (TC) by radiographic findings. He had been hypercalcemic and hyperphosphatemic with high doses of vitamin D for chronic kidney disease-mineral and bone disorder. We then stopped vitamin D to manage the hypercalcemia and hyperphosphatemia; however, the TC did not regress after 1.5 years, thus the patient underwent renal transplantation. Subsequently, the TC gradually but almost completely disappeared over the next 1.5 years. A renal transplantation was thus found to be useful for the successful treatment of TC.
