Ozturk Feyza Yener , Canat M Masum , Erol R Selvinaz , Karatas Savas , Kuzu Idris , Altuntas Yuksel

Thyroidectomy is the definitive treatment for toxic multinodular goiter (TXMNG). Surgery should be performed when the patient is euthyroid which decreases perioperative cardiac risks. Plasmapheresis is a procedure that removes the thyroid hormones from the circulation. It is an alternative method in case of resistance or contraindications to anti thyroid drugs. Role of plasmapheresis in the treatment of TXMNG is not fully determined in the literature. We report a case with TXM...

Introduction: Atypical parathyroid tumour (APT) is a rare cause of primary hyperparathyroidism (PHPT) with a frequency of 1.2-1.3%. APT is a lesion with suspicious clinical and histological features of malignancy which does not completely respect the World Health Organization (WHO) criteria for diagnosis of Parathyroid Carcinoma (PC). There is a well-known association with PHT and medullary thyroid carcinoma for multiple endocrine neoplasia. However, concurrence of thyroid pap...
