Tumoral calcinosis causing bone erosion in a renal dialysis patient.

Tumoral calcinosis is a rare disorder manifest by large calcific periarticular masses. Associated bone destruction has been described previously only once. The radiographic and computed tomographic (CT) findings of bone erosion in a case of tumoral calcinosis in a renal dialysis patient are presented. Although the presence of bone destruction may suggest a neoplasm, it does not exclude the diagnosis of tumoral calcinosis.
