[Primary hyperparathyroidism. 50 personal cases]

On the basis of a study of a series of 50 personal cases, the results of which are reported, and of a series of 2800 cases from the literature, the authors describe certain radiological and clinical aspects of primary hyperparathyroidism and the conditions under which this disease may appear. They emphasize the value of the different laboratory investigations for determining disturbances in phosphorus-calcium metabolism and of the study of bone histology, particularly the quantitative study of iliac bone biopsies. They discuss the various aspects of their methods of surgical treatment (pre-operative location of the tumour, surgical problems, early and later sequelae) and finally describe the indications for surgery.
