Introduction: The predictors of malignancy are important for decision of appropriate management in nodules with atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS). Our aim was to determine the ultrasonographical, clinical and biochemical predictors of malignancy in these patients.Methods: A total of 427 patients with Bethesda Category III (AUS/FLUS) thyroid nodules were included in this retrospective study. We d...

Background: Fine needle aspiration biopsy (FNAB) has proven to be the most valuable diagnostic procedure for preoperative discrimination of benign and malignant nodules. Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) has standardized reporting and cytomorphological criteria in aspiration smears. In this study, we aimed to determine malignancy rates in nodules with different cytology results and diagnostic value of TBSRTC for variants of papillary thyroid carcinom...

Introduction: Papillary thyroid carcinoma(PTC) and medullary thyroid carcinoma(MTC) have always been considered different tumors. Concomitant presence of MTC and PTC in the same patient is a rare clinical event.Case report: A 43 year-old woman admitted with fatigue, a serum thyrotropin of 4.6 uIU/ml and a 15×11 mm thyroid nodule in right lobe detected in another center. Fine needle aspiration(FNA) of the nodule was consistent with MTC. In family his...
