Tumoral calcinosis in the neck.
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.
