Tumoral calcinosis manifests soft-tissue calcification, usually near major joints. It variably includes hyperphosphatemia, elevated 1,25-dihydroxycalciferol, and an affected sibling. Serum calcium, alkaline phosphatase, and parathyroid hormone are normal. Tumoral calcinosis of the head and neck is very rare, but this diagnosis should be considered when x-ray film of a poorly defined mass shows irregular soft-tissue calcification.

Tumoral calcinosis involves formation of periarticular calcified soft tissue masses. Experimental evidence suggests a metabolic etiology with dietary restriction of calcium and phosphorus as beneficial therapy. We prospectively monitored serum levels of calcium, phosphorous, alkaline phosphatase, and erythrocyte sedimentation rate (ESR) while successfully treating a patient with tumoral calcinosis. The values were compared with changes on serial radiographic and radionuclide bone and gallium images. Our work suggests using serial serum phosphate levels and the ESR as the most sensitive indications of progress in dietary treatment of tumoral calcinosis.

Tumoral calcinosis is a rare disorder of mineral metabolism among adolescents and young adults characterized by deposition of calcific masses around large joints. It is less commonly reported in pediatric population and commonly mistaken for bone tumors. Typical lab parameters include hyperphosphatemia with normal levels of serum calcium, parathyroid hormone (PTH) and alkaline phosphatase. A ten-year-old boy with typical features of tumoral calcinosis is presented.
