Abstract
Tumoral calcinosis is a rare disease characterized by periarticular calcification, hyperphosphatemia and normocalcemia Two cases of tumoral calcinosis have been followed up and examined. The masses occur in highest frequency about the hips, elbows and shoulders, but the involvement of the hands and knee is uncommon. However, our cases had calcific tumors of the knees. Radiographically it has been defined by the presence of periarticular calcific deposits varying in size. One of the patients was found to have unusual diffuse soft tissue calcification of the lower extremities. This may suggest an underlying defect in phosphate metabolism.
