Tumoral calcinosis is an uncommon and severe complication of hemodialysis therapy. The most important pathogenic factor involved in uremic tumoral calcinosis is an increase in calcium-phosphorus product, not necessarily related to hyperparathyroidism. We report here a patient on hemodialysis who presented with increasing multifocal and uncommon sites of massive calcifications. The patient was examined, and a diagnosis of uremic tumor calcinosis was made. The patient was treated with the noncalcemic phosphate binder sevelamer, a strict diet, multiple hemodialysis sessions per week, and a low calcium dialysate, with improvement on biological findings a decrease in the volume of some tumors on his fingers and a global stable disease. Some nodes in hands and feet disappeared; in other sites, their diameter was reduced, and the largest nodule decreased from 5- to 2-cm diameter.
