In the first 40 years, after its recognition as a clinical entity, primary hyperparathyroidism (HPT) presented as a disorder with kidney stones and bone disease. Now, HPT is often recognized as a result of biochemical screening, or as part of an evaluation for decreased bone mass [1, 2]. The diagnosis of HPT is usually made by finding an inappropriately elevated serum parathyroid hormone (PTH) concentration associated with hypercalcaemia. The current understanding of molecular mechanisms of calcium regulation by calcium-sensing receptor (CaSR) and proliferation of parathyroid cells by oncogenes (RET) and tumour suppressor genes (MEN1 gene, HRPT2 gene) has in part changed the management of HPT.

Serum ionized calcium concentrations are normally maintained within the very narrow range achieved through a tightly regulated calcium-PTH homeostatic system [3]. PTH is secreted almost instantaneously in response to very slight reductions in serum ionized calcium, which are sensed by
