title: [Primary hyperparathyroidism in patient with thyroid papillary cancer--case report].
abstract: Patient with primary hyperparathyroidism and papillary thyroid cancer was presented. The female patient, 45 years old, because of papillary thyroid cancer was treated in the typical way by total strumectomy with lymphadenectomy following by 1131 therapy and L-thyroxine suppressive therapy. After 9 years, during one of control routine examinations, the serum levels of calcium and parathormone were increased (Ca2+: 1.449 mmol/l; Ca: 2.91 mmol/l; PTH: 256 pg/ml). Primary hyperparathyroidism was diagnosed and the patient underwent the surgery in the anterior cervical region with removal of parathyroid adenoma, histopathologically confirmed. Serum PTH level together with calcium levels decreased into the normal range. The coexistence of primary hyperparathyroidism and thyroid non-medullary cancer was already reported, but in this case the time of the onset was delayed. Due to the fact that patients after the treatment of thyroid non-medullary cancer, especially after of the neck radiation or radioactive iodine therapy, are more exposed to develop hyperparathyroidism, complete and wide examinations, even many years after treatment of thyroid cancer, are needed.
