title: Primary hyperparathyroidism with triple cancers consisting of renal cell carcinoma, nasopharynx carcinoma and thyroid carcinoma.
abstract: The first case of primary hyperparathyroidism associated with renal cell carcinoma, nasopharynx carcinoma and thyroid carcinoma is reported. Selective venous sampling with radioimmunoassays for parathyroid hormone was helpful in the differentiation of primary hyperparathyroidism from hypercalcemia associated with malignancy.
