title: Primary hyperparathyroidism and breast cancer.
abstract: Three cases demonstrating the coexistence of primary hyperparathyroidism and breast carcinoma with the disappearance of hypercalcemia following removal of parathyroid adenomas are presented. In these cases, the patients had the typical diagnostic findings of primary hyperparathyroidism. Reluctance to perform neck explorations in such patients does not appear warranted.
