Hyperphosphatemic Tumoral Calcinosis

Abstract

Tumoral calcinosis is a rare entity presenting with periarticular calcium deposits, leading to multiple swellings and biochemical hyperphosphatemia and normocalcemia. Skeletal scintigraphy in these cases is helpful by providing a whole-body survey and delineating the common multifocality of this entity. We present the case of a 16-year-old boy with multiple swellings around the knee and elbow joints, having developed over 4 years and diagnosed as tumor calcinosis.
