    Progesterone receptor expression in fibromuscular dysplasia: A report of two unusual cases
    (BAYCINAR MEDICAL PUBL-BAYCINAR TIBBI YAYINCILIK, 2019-01-01) Erkan, Murat; Canberk, Sule; Onenerk, Mine; Sayman, Elif; Gunes, Pembegul; Orhan, Gokcen
    Fibromuscular dysplasia is rarely biopsied. Progesterone receptor expression in myofibroblastic cells is useful for the histopathological evaluation in difficult-to-diagnose cases. Herein, we report two unusual cases of fibromuscular dysplasia in which progesterone receptor expression was shown in vessel sections.

    Avoidance of unnecessary fine-needle aspiration with the use of the Thyroid Imaging Reporting Data System classification and strain elastography based on The Bethesda System for Reporting Thyroid Cytopathology
    (SPANDIDOS PUBL LTD, 2016-01-01) Erkan, Murat; Canberk, Sule; Kilicoglu, Gamze Z.; Onenerk, Mine; Uludokumaci, Atay; Gunes, Pembegul; Atasoy, Tugba
    Thyroid fine-needle aspiration (FNA) biopsy has been widely accepted as an accurate and cost-effective tool in the management of thyroid nodules. To avoid unnecessary FNAs and provide appropriate management, patient evaluation should be based on a multidisciplinary approach. For this purpose, the Thyroid Imaging Reporting and Data System (TI-RADS) and strain elastography (SE) were proposed as tools for the risk assessment of malignancy in thyroid nodules. The aim of the present study was to analyze the utility of TI-RADS system and SE, along with FNA, and prospectively evaluate 369 consecutive patients referred for FNA of a thyroid nodule. TI-RADS was tested against The Bethesda System for Reporting Thyroid Cytopathology to determine whether there was an agreement between the two classification systems

    A Different Perspective on Evaluating the Malignancy Rate of the Non-Diagnostic Category of the Bethesda System for Reporting Thyroid Cytopathology: A Single Institute Experience and Review of the Literature

    Objective To determine the malignancy rate in the non-diagnostic (ND) category of the Bethesda System for Reporting Thyroid Cytopathology (BSRTC) based on a different approach in relation to histopathology diagnoses. Study Design All ND fine needle aspirations (FNAs) that were performed under ultrasound guidance by an interventional radiologist with rapid on-site evaluation were included in the study. Slides were reevaluated to identify the cause of inadequacy as ``qualitative{''} or ``quantitative.{''} The malignancy rate of the ND category was assessed. Nodule/patient characteristics were compared between benign and malignant cases within the study cohort. Results The study cohort consisted of 192 ND aspirations. Overall there were 156 (81.3\%) women and 36 (18.7\%) men with a mean age of 50.6 years (range 24-82 years). The malignancy rate was 4.7\%. None of the nodules (size, consistency, and number) or patient characteristics (gender and age) were found to be predictive of malignancy. Conclusion The malignancy rate of the ND category was high when compared to BSRTC predictions, but at the low end of the reported malignancy rates in the literature. Our results revealed that cyto-histopathologic correlation and method of malignancy rate estimation could have an effect on a wide range of reported malignancy rates. Furthermore, patient/nodule dependent factors were not statistically found to be predictive of malignancy.
