A Case of Parathyroid Carcinoma with Systemic Calcification / 영남의대학술지

ABSTRACT

Hyperparathyroidism due to parathyroid cancer is rare. It is difficult to diagnose preoperatively but there should be an increased index of suspicion in those parathyroid Patient with palpable neck masses, profound hypercalcemia(greater than 14mg/dl), made increase of the parathyroid hormone level to greater than twice normal, and significant metabolic complications. In parathyroid cancer, systemic calcinosis is an extremely rare manifestation. The most common metastatic calcification site is lung and the other involved site is stomach, liver, skin and heart. After resection of parathyroid tumor, this systemic calcinosis is self-limiting. We experienced a patient with primary hyperparathyroidsm, presented with metastatic calcification in the lung and stomach disappeared by successful parathyroidectomy.
