The incidence of thyroid cancer in young adults is rising. Differentiated carcinoma (ie, papillary, follicular, and their variants) and medullary thyroid carcinoma (MTC) represent the two most common subtypes, with differing etiologies, prognoses, and management strategies. Ultrasound (US)-guided fine needle aspiration (FNA) is the best initial test for evaluating a nodule or mass suspicious fo...
INTRODUCTION Thyroid swelling is common problem among South Asian women. Although benign nodules far outnumber cancerous lesions, the risk of malignancy needs to be evaluated preoperatively for which fine needle aspiration cytology (FNAC) is widely used. Bethesda system for reporting thyroid cytopathology (BSRTC) was introduced to streamline the reporting of thyroid aspirates. We aimed to evalu...
introduction although thyroid nodules are usually benign, malignancy must always be ruled out. many efforts have been made to find. malignant nodules and reduce the number of unnecessary operations. in this study, our aim was to examine, after the more extensive use of fine needle aspiration (fna), whether the incidence of cancer finding has been increased. materials and methods we studied retr...
PURPOSE To analyze which sonographic features of thyroid nodules with macrocalcifications were predictable of thyroid malignancy. MATERIALS AND METHODS We reviewed sonographic findings of 854 macrocalcified thyroid nodules in patients who underwent fine needle aspiration biopsy between December 2009 and January 2011. There were 171 non-diagnostic aspirations, 34 nodules with category 3, 4, 5 ...
Background: Thyroid nodules are common problems encountered in our routine practice. Fine needle aspiration cytology (FNAC) is the most accurate and cost-effective method for evaluating thyroid nodules. It procedure of choice identifying patients who require surgical excision. Methods: This a retrospective single-center observational study Salmaniya Medical Complex, tertiary care center, Kingdo...
OBJECTIVE The objective of this retrospective study was to develop and validate a simple diagnostic prediction model by using ultrasound (US) features of thyroid nodules obtained from multicenter retrospective data. MATERIALS AND METHODS Patient data were collected from 20 different institutions and the data included 2000 thyroid nodules from 1796 patients. For developing a diagnostic predict...
hbme-l is an antimesothelial monoclonal antibody that recognizes an unknown antigen on microvilli of mesothelial cells. the antibody is only relatively specific for mesothelium and is used in the differential diagnosis of mesothelioma and adenocarcinoma within the context of an appropriate immuno-histochemical panel. hbme-l has also been reported to strongly and uniformly stain papillary and fo...
BACKGROUND The Hounsfield unit (HU) ratio of thyroid nodules was assessed compared to the contralateral thyroid lobe on noncontrast computed tomography (CT) to stratify further the risk of malignancy in thyroid incidentalomas found on 18F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography/CT (PET/CT). METHODS This retrospective analysis included 82 patients who had thyroid incidental...
BACKGROUND Thyroid cancer rates are on the rise worldwide with over 5000 new cases estimated in Canada in 2012. The American Thyroid Association recommends the use of fine-needle aspiration biopsy (FNA) in the workup of thyroid nodules. Studies show that thyroid FNA accuracy may vary based on interpretation by cytopathologists in academic versus community centres. To date, there has been no lit...
