Oxyphil parathyroid adenoma associated with primary hyperparathyroidism and marked post-operative hungry bone

Abstract:
A rare case of functioning oxyphil parathyroid adenoma associated with primary hyperparathyroidism and marked hungry bone syndrome was revealed in a 29-year-old man with hypercalcemia and elevated circulating parathyroid hormone (PTH) level. A large parathyroid tumor weighing 8.4 g was resected and proved to be an oxyphil adenoma. Hypocalcemia was sustained after the operation, despite intensive calcium supplementation. During the postoperative 8 months, bone mineral density at the lumbar spine increased dramatically from 0.892 g/cm2 to 1.244 g/cm2, and whole body bone mineral content increased from 1,913.4 g to 2,419.2 g. This case gives insight to the reversibility of bone loss in this disorder.
