Tumoral calcinosis in hemodialysis patients. A review of three cases.

Soft tissue calcification are common in chronic hemodialysis patients and often affect the periarticular tissues, where they occasionally form tumoral masses. In a retrospective study of 254 hemodialysis patients we identified three such cases. Affected sites were the wrist, shoulder, and chest wall. None of the patients had secondary hyperparathyroidism. A discussion is provided of the roentgenographic and clinical features of tumoral calcinosis, of current pathogenic hypotheses, and of available treatments.
