Normocalcemic Primary Hyperparathyroidism

Normocalcemic Primary Hyperparathyroidism (NC-PHPT) is a clinical entity characterized by normal serum calcium and persistently elevated parathyroid (PTH) levels. These patients have no obvious causes for secondary hyperparathyroidism such as vitamin D deficiency and renal insufficiency [1,2-16,17]. None of the patients had clear evidence of gastrointestinal disease. Although the entity NC-PHPT...

Normocalcemic primary hyperparathyroidism.

Primary hyperparathyroidism, a common endocrine disorder, is traditionally defined by hypercalcemia and elevated levels of parathyroid hormone (PTH). A newer presentation of primary hyperparathyroidism has been described over the past decade, in which PTH is elevated but serum calcium is consistently normal, in the absence of secondary causes of hyperparathyroidism, such as renal disease or vit...

Normocalcemic Primary Hyperparathyroidism

Normocalcemic primary hyperparathyroidism is a new entity which possibly represents a fruste form of the classic clinically symptomatic disease and which has generated a considerable scientific interest in the last decade. Its official recognition is just as recent as in 2008, when an international conference took place for clarifying its nature and relevance (Bilezikian et al., 2009). Its true...

Mediastinal parathyroid adenoma causing primary hyperparathyroidism.

An ectopically placed parathyroid adenoma in the anterior mediastinum is a rare cause of persistent or recurrent primary hyperparathyroidism (PHPT) and is recognized as an important cause of failed primary neck exploration. We encountered 3 such cases amongst 70 surgically treated patients with PHPT (4.3%) over a 20-year period. In 2 cases, the offending adenoma could be removed at first explor...
