[Primary hyperparathyroidism].

For thirty years, primary hyperparathyroidism is recognized as a frequent endocrine disease which is, most often, "non symptomatic" that is without nephrolithiasis or osteitis fibrosa cystica. Our knowledge in the pathophysiology has greatly grown and diagnosis of primary hyperparathyroidism is frequently easy. The only curative treatment is surgery and the indications have been codified by several consensus conferences.
