Parathyroid Tumors
Key Points
Parathyroid tumors secreteparathyroid hormone(PTH) causing hyperparathyroidism and hypercalcemia. Parathyroid adenomas are most often isolated solitary adenomas but sometimes occur with other endocrine tumors as part of a multiple endocrine neoplasia syndrome. Parathyroid cancers cause hyperparathyroidism and hypercalcemia that is often more severe than with adenomas. Surgical resection is often curative for both parathyroid adenoma and carcinoma.
