Abstract:
Tumoral calcinosis is a periarticular calcific lesion and rare complication in patients with maintenance hemodialysis. The pathogenesis of tumoral calcinosis is poorly understood but may be due to elevated serum phosphorus, a high calcium phosphorus (Ca x P) product or secondary hyperparathyroidism in hemodialysis patients. A 30-year-old man presented with pain and palpable mass of left shoulder. He had been on maintenance hemodialysis with high flux dialyzer for 10 years. Laboratory finding showed hyperphosphatemia and elevated intact PTH concentration. A shoulder X-ray and CT scan demonstrated a massive calcification. Following partial resection, pain was relieved. Here we report a case of tumoral calcinosis of shoulder in a hemodialysis patient with untreated hyperphosphatemia and secondary hyperparathyroidism.
