[A case of primary hyperparathyroidism. Clinical contribution]

The authors discusses some clinical, laboratory and instrumental problems of a reported case of primary hyperparathyroidism caused by adenoma from the point of view of medical literature. Nethertheless the lack of the specificity of the clinical manifestations and the slowly progressive evolution of this disease, primary hyperparatiroidism must be suspected in the presence of his most common multifarious complications. The finding of hypercalcemia in these conditions and from screening procedures requests parathyroid functional tests and exclusion of other causes of which chiefly pseudohyperparathyroidism may be difficult to be differentiated. The early diagnosis and correction of the parathyroid lesion avoid further damage and regression of many preoperatory complications.
