Since the patient did not improve, a neck exploration was done, and an adenomatous enlargement of one of the parathyroids was found and removed. The patient steadily improved.1The demonstration that a serious metabolic disorder of bone could be surgically corrected stimulated a widespread interest in the early diagnosis of primary hyperparathyroidism which has continued to the present. Metabolic bone disease of the osteitis fibrosa variety, nephrolithiasis or nephrocalcinosis, or a combination of these manifestations, have been the clinical hallmarks of primary hyperparathyroidism.In 1957 St. Goar called attention to the frequency with which gastrointestinal symptoms
