Multiple parathyroid adenomas have been an unusual cause of primary hyperparathyroidism. Contralateral neck exploration might not be required if normal microscopic features are seen in the ipsilateral gland where an adenoma was found. We have treated four consecutive patients with multiple parathyroid adenomas and reemphasize the principle of thorough bilateral neck exploration. Excision of only the enlarged parathyroid glands was performed; subtotal parathyroidectomy has not been required.
