Case report of tumoral calcinosis in a peritoneal dialysis patient with tertiary hyperparathyroidism and systemic lupus erythematosus.

Tumoral calcinosis (TC) is a rare condition characterized by dystrophic calcinosis. TC in end stage kidney disease is associated with severe hyperparathyroidism. It is radiologically characterized by multilobulated cystic calcifications in periarticular regions without erosive arthropathy or osseus destruction. Secondary TC may necessitate medical or surgical parathyroidectomy for symptom control.
