Introduction: Atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS) termed as Bethesda Category III constitute 15–30% of thyroid cytology. However, the risk of malignancy in this heterogenous category is estimated as 5–15%. The recent studies has been reported the malignancy rate in the wide range of 6–48%. This causes surgical approach variability between different centers. We aimed to evaluate the initial malignancy rate...

Introduction: Hyalinizing trabecular tumor is a very rare neoplasm of thyroid and can be misinterpreted as papillary or medullary cancer in fine needle aspiration biopsy (FNAB).Case report: Multinodular goiter was detected in a 65 years old woman using metformin and L-thyroxine for impaired blood glucose and Hashimoto thyroiditis, respectively. FNAB was performed in two nodules and reported as suspicious for malignancy and benign. She underwent total thy...

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: 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...

Atypical tumors were identified in 15% of pituitary adenomas, and they tended to be aggressive, invasive macroadenomas. WHO classification of atypical pituitary adenomas include; Ki-67 proliferative index >3%, excessive p53 immunoreactivity, and ≥ 2 mitotic figures per 10 high-powered fields. Pituitary carcinomas are extremely rare tumors with cerebrospinal or extracranial metastasis.Case: A 31 years old man with symptoms of stuffy nose and sno...
