Parathyroid carcinoma: location of pelvic metastases by parathyroid hormone assay.
A metastasis from a functioning parathyroid carcinoma was located by PTH radioimmunoassay and selective venous catheterization. The site of the metastasis, verified at autopsy, was in the right side of the pelvis. This is the most distant reported location for metastatic parathyroid carcinoma. The patient's plasma immunoreactive PTH rose more than twofold in response to induced hypocalcemia. This suggests that relative hypocalcemia, induced therapeutically in such patients, may result in a higher chronic level of PTH secretion.
