Primary hyperparathyroidism (PHPT) is mostly due to a benign parathyroid tumor (99%). Some have parathyroid ‘atypical adenomas’, rare tumors with histological features of parathyroid cancer (PC) (fibrous trabeculae, thick fibrous bands, mitotic figures in parenchymal cells), without local invasion or metastasis. We evaluated 20 patients with histological diagnosis of atypical adenomas. Patients were 13 women and seven males (mean age: 55±13 yrs). Nineteen patien...

The 4th International Workshop for the management of asymptomatic PHPT included the presence of hypercalciuria (dUCa> 400 mg/day) and increased stone risk by biochemical stone risk profile as criteria for surgery. Our aim was to evaluate the complete stone risk profile in 176 consecutive patients with asymptomatic PHPT. We recorded clinical and biochemical data, including 24 hours urinary measurements of the following parameters: volume and pH, creatinine, calcium, magnesi...
