Tumoral calcinosis of the foot.

Abstract

Tumoral calcinosis is characterized by periarticular deposition of calcium phosphate, usually in the setting of normocalcemia and hyperphosphatemia. The term tumoral calcinosis can be used to describe lesions with periarticular deposition of calcium phosphate resulting either from a primary disorder or a secondary disorder, such as renal failure with associated secondary hyperparathyroidism. Treatment entails phosphate deprivation, control of any primary disease processes such as secondary hyperparathyroidism, and resection for recalcitrant symptoms. We present a case of tumoral calcinosis involving the foot which required resection and ultimately hyperparathyroidectomy.
