Detection and management of parathyroid tumors

Hyperparathyroidism is due to enlargement of one or more parathyroid glands and is most often treated by surgical resection. Recent advances have taken place in regard to preoperative localization and refinement of surgical technique. The underlying mechanisms of parathyroid tumorigenesis are just beginning to be unraveled. The management of asymptomatic hyperparathyroidism remains controversial, although a liberal approach to surgery has become more widely accepted.
