Two cases of a rare parathyroid adenoma associated with a nonmedullary carcinoma of the thyroid are presented. The indication for surgery was primarily hyperparathyroidism in one case and a thyroid nodule in the other. The additional lesions in both cases were incidental findings. The incidence of nonmedullary carcinoma of the thyroid among patients with parathyroid adenomata is reported as 4.5%, an incidence manyfold higher than that in the general population. It thus seems justified that a patient undergoing surgery for either parathyroid or thyroid disease should be evaluated pre- and intraoperatively for abnormalities of the adjacent gland or glands.
