Tumoral Calcinosis of the Foot

Abstract

Tumoral calcinosis is a disorder characterized by deposits of calcium phosphate in the subcutaneous tissues near large joints. While often resembling a neoplasm, the soft tissue deposits of tumoral calcinosis are benign in nature. The deposits can, however, cause significant morbidity to patients due to tissue pressure or impingement. The focus of this case report will include the presentation, radiographic examinations, clinical course, and treatment of a 90-year-old female patient presenting for evaluation of a painful plantar right foot soft tissue mass associated with chronic renal failure and secondary hyperparathyroidism.

Level of Evidence: Therapeutic, Level IV
