title: [Metastatic calcification simulating a sacral tumor in a patient on periodic dialysis].
abstract: Renal osteodystrophy is usually a prominent feature in patients undergoing chronic hemodialysis. Metastatic calcifications are a frequent finding when secondary hyperparathyroidism is associated. We present a patient with a sacral soft tissue calcification resembling a malignant tumour.
