Roaa S Alsolaimani MD FRCPC

Abstract: Tumoral calcinosis is a rare disease characterized by calcium deposition in different peri-articular soft tissue regions. It is classified into three categories Primary normo-phosphatemic tumoral calcinosis, Primary hyper-phosphatemic tumoral calcinosis and secondary tumoral calcinosis. The primary types mainly manifest in childhood or adolescence as painless, firm, masses around the joints that may lead to joint function limitations specially when large in size. We report an unusual late presentation of primary tumoral calcinosis in a 67-year-old lady. Treatment with one dose of Zolendronic acid seemed to stop disease progression.
