Rare Presentation of Primary Hyperparathyroidism in a Young Woman.

Even though primary hyperparathyroidism (PHPT) is a common endocrine disorder, due to better and more regular screening, the usual presentation is only seen in less than 15% of cases of PHPT. The authors present the case of a young female patient with a previous medical history of depression and nephrolithiasis, with one year of bone pain, that had become progressively worse and disabling. In the initial work-up, several lytic bone lesions and moderate hypercalcemia were found, leading to admission of the patient in the Internal Medicine ward for investigation and treatment.
