Aim: Although thyroid nodules located in isthmus were less frequent, papillary thyroid cancer in this location was reported to be more aggressive in some studies. Our aim was to evaluate hormonal, ultrasonographic, and cytopathologic features of nodules located in isthmus (isthmic nodules).Material and methods: Data of patients who underwent thyroidectomy between 2006–2014 were reviewed retrospectively. Hormonal, ultrasonographic, and cytopathologic...

Aim: It has been reported that thyrotrophin receptor antibody (TRAb) is associated with frequency and aggressiveness of thyroid cancer in patients with Graves disease (GD). However, there is not any data regarding the effects of TRAb on cytology and histopathology results of patients with nodular GD. Thus, the aim of the present study is to evaluate the effects of TRAb on cytology and histopathology results in patients with nodular or multinodular thyroid disease on the basis ...

Introduction: Hepatic dysfunction in hyperthyroidism may occur due to high thyroid hormones, medications or associated autoimmune liver disease. Autoimmune hepatitis or primary biliary cirrhosis (PBC) has rarely been reported in Graves’ disease. We report a patient presenting with pruritus and diagnosed as accompanying PBC and Graves’ disease.Case: A 50 years old female patient applied with progressive pruritus for at least 4 months. Laboratory...

Aim: Atypia/follicular lesion of undetermined significance(AUS/FLUS) is a category of thyroid cytology with features that are neither definitely benign or malignant. We aimed to determine whether specific cytologic or architectural features are associated with malignancy in AUS/FLUS category of Bethesda system according to subgroups.Methods: The specimens of patients who underwent surgery with preoperative thyroid fine neeedle aspiration (FNA) biopsies o...

Introduction: Although malignancy rate is low in thyroid nodules with nondiagnostic (ND) cytology, it is reported as higher in persistent ND nodules. We aimed to determine the role of ultrasonography (US) features and Thyroid Imaging Reporting and Data System (TIRADS) in the prediction of malignancy in patients with persistent ND cytology.Methods: 246 patients who underwent thyroidectomy with an indication of at least two ND cytologies were included in t...

Introduction: Recently, it has been suggested that thyrotropin (TSH) concentration can be used as a marker for prediction of thyroid malignancy. However, the association between the cytology results and TSH levels is not clear. In this study, we aimed to investigate the relationship between TSH levels and Bethesda categories and determine the role of TSH levels in prediction of malignancy in patients with different Bethesda categories.Methods: The data o...

Introduction: Incidental thyroid carcinoma (ITC) in patients operated on for a benign disease is frequent. ITC characteristics in patients operated for malign disease, but not sampled by fine needle aspiration (FNA) or seen in ultrasonography, is unknown. We aimed to compare ITC with nonincidental ITC (NITC) in this study.Material and method: Retrospective analyses of 918 individual patients who were operated for benign and malign thyroid disease in our ...

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: In this study, we aimed to evaluate impact of multifocality, tumor number and total tumor diameter on clinicopathological features of PTC.Methods: Medical records of 912 patients who underwent thyroidectomy and diagnosed with PTC were reviewed retrospectively. Patients were grouped into 4 according to number of tumoral foci; N1 (1 focus), N2 (2 foci), N3 (3 foci) and N4 (≥ 4 foci). The diameter of the largest tumor was considered as t...

Introduction: In this study, we aimed to evaluate the usefulness of ratio of primary tumor diameter to total tumor diameter as a new parameter for the differentiation of agressive and favorable papillary thyroid microcarcinomas (PTMC).Methods: The diameter of the largest tumor focus was taken as the primary tumour diameter (PTD). For multifocal tumors, total tumor diameter (TTD) was calculated as the sum of the maximal diameter of each lesion. A ratio wa...
