Tumoral calcinosis while undergoing continuous ambulatory peritoneal dialysis: A case report

Automatic peritoneal dialysis to prevent ectopic calcification

Abstract

We report a case of tumoral calcinosis of the left knee joint, both shoulders and the fingers of the right hand as a result of hyperphosphatemia in a 26-year-old male on continuous ambulatory peritoneal dialysis (CAPD) for 6 years. Several conservative treatments failed to reduce the level of serum phosphorus, and tumorectomy of both shoulders and the fingers was performed for pain control. Automatic peritoneal dialysis (continuous ambulatory peritoneal dialysis plus nightly intermittent peritoneal dialysis) was performed to prevent ectopic calcification. The patient's clinical course following automatic peritoneal dialysis was uneventful, and during the 15-month follow-up period there was no evidence of recurrence. We believe that automatic peritoneal dialysis combined with diettherapy can enhance the efficiency of dialysis and prevent the recurrence of ectopic calcification.
