Neonatal primary hyperparathyroidism: total parathyroidectomy with autotransplantation of cryopreserved parathyroid tissue.

Primary neonatal hyperparathyroidism is a life threatening disease because of severe hypercalcemia. The best therapy is early total parathyroidectomy which requires permanent replacement therapy. We describe the first case treated by total parathyroidectomy and late autotransplantation of cryopreserved parathyroid tissue. Twenty months after transplantation, serum calcium and phosphate levels are normal in the absence of any supplementary treatment.
