Core Tip

Core tip: Tumoral calcinosis, a very rare disease entity, occurred in the described patient with end-stage renal disease due to disturbed calcium phosphate metabolism and insufficient quality of continuous ambulatory peritoneal dialysis. Complete remission was achieved by modification of the medical treatment and by switching to hemodialysis, which improved the dialysis quality. In general, to recuperate severe tumoral calcinosis, the treatment must be selected based on an understanding of the clinical background and the quality of the renal replacement therapy regime. In conclusion, this case report will significantly contribute to the reader’s understanding of tumoral calcinosis pathogenesis and treatment in patients with end-stage renal disease.
