Tumoral calcinosis of the foot with unusual presentation in an 11-year-old boy: a case report and review of literature.

Tumoral calcinosis is an uncommon disorder characterized by development of calcified masses within the soft tissues near the large joints such as the hip, elbow and shoulder and rarely occurs in the foot. We report the clinical, radiological and magnetic resonance imaging findings in a case of tumoral calcinosis of the foot observed in an 11-year-old boy which caused erosion of underlying bone and describe the surgical treatment and pathology results.
