Introduction: Parathyroid cancer (PC) is rare accounting for <1% of all presentations. Tumors that demonstrate these atypical features and do not fulfill criteria for carcinoma can be classified as atypical adenomas (APA). Herein we aimed to evaluate the clinical and biochemical features of the patients with an atypical parathyroid adenoma or carcinoma and compare it with benign parathyroid adenomas.Method: Twenty-eight patients who were operated for...

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: Differential diagnosis of a thyroid nodule is difficult if it is a follicular lesion. Follicular lesions include follicular adenoma (FA) or a malign neoplasm (follicular cancer (FC) or follicular variant of papillary thyroid carcinoma (FVPTC)). Cytology can’t separate benign from malignant condition in follicular lesions. Differential diagnosis is important because patients often undergo less than ideal interventions, such as a total thyroidectomy for a benign...

Introduction: Primary hyperparatyhyroidism (PHPT) is usually caused by single or multiple adenomas and cancer is rare accounting for <1% of all presentations. The presence of certain cytological and architectural features such as adherence to adjacent organs, a solid growth pattern, broad bands of fibrosis, cytological atypia, and an irregular growth contour do not indicate malignancy but are recognised as atypical features encountered more commonly in malignant than benig...

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...

Aim: We aimed to investigate the relation between preoperative serum thyrotrophin (TSH) and clinicopathological features in patients with papillary thyroid carcinoma (PTC) and microcarcinoma (PTMC).Methods: Patients who underwent thyroidectomy and diagnosed to have benign nodular disease or PTC/PTMC in our clinic were evaluated retrospectively. Patients with a previous history of thyroid surgery, patients using antithyroid medications or thyroid hormone ...
