Clinical Summary:
This 65 year old man presented with recurrent hyperparathyroidism. He had had a parathyroid “adenoma” removed in 1985 and was subsequently well. In 2012 hypercalcemia was noted. He had no symptoms although he was a poor historian and was mentally challenged. At exploration a 14 gram mass was removed from the left upper neck. Additional parathyroid was removed and a portion of the large gland was implanted in his left arm. Postoperatively his calcium and PTH levels normalized. The patient has several first degree relatives with parathyroid and pancreatic tumors. Clinically the family is diagnosed with MEN I (Wermer syndrome).
Pertinent Laboratory Data:
Serum calcium range about 13 mg/dl; PTH over 1000 units.
