Background: Fine-needle aspiration cytology (FNAC) of thyroid is a rapid diagnostic test for thyroid nodules. The Bethesda system classifies thyroid FNAC into six categories. Each category is linked to a malignancy risk and has recommended clinical management. The aim of this study was to analyze the thyroid cytology smears by Bethesda system and to assess the frequency of various categories and to correlate it previous published studies. Category wise management is also discussed in detail.Methods: A total of 388 thyroid FNAC samples were examined from January 2017 to June 2018 in the Department of Pathology, in Medanta- The Medicity Gurugram.Results: A total of 388 cases were reported according to Bethesda system of reporting. Categories were as follows: I (14.69%), II (61.85%), III (11.34%), IV (2.57%), V (2.660%), VI (4.91%) nodules.Conclusions: The Bethesda System for reporting thyroid cytopathology proved to be an excellent reporting system and it puts clinician and the cytopathologist on the same page and easier to communicate regarding diagnosis.

BACKGROUND The Bethesda system of reporting thyroid cytopathology is an outstanding and systematic approach of reporting thyroid cytology samples, thereby reducing the communication gap between cytopathologist and clinician, leading to a better patient care approach. We aim to study the thyroid fine needle aspiration (FNA) using the Bethesda system and evaluate its accuracy taking histopathology as gold standard. METHODS This was a descriptive study including 200 consecutive cases which came to our cytology department between January 2014 and December 2014. All thyroid fine needle aspiration cytology (FNAC) were categorised as per the Bethesda system and followed up with corresponding histopathology. RESULTS Out of the 200 cases, adequacy criteria was met in 196 (98 %) cases. 176 (88 %) cases fell in the benign category, 4 (2 %) cases were inadequate samples, 8 (4 %) showed features of follicular neoplasm / suspicious of follicular neoplasm and 12 (6 %) were malignant lesions. Histopathology follow up was available for all cases. Statistical analysis showed a specificity of 100 % (high), sensitivity of 40 % (low). Positive predictive value was 100 %, negative predictive value was 90.4 %. Accuracy rate was 91 %. CONCLUSIONS Interpreting the thyroid FNAC results using Bethesda system allowed a superior interlaboratory agreement leading to improved clinical management. KEYWORDS Thyroid, Cytology, Bethesda

Background: Fine needle aspiration cytology (FNAC) is very simple, rapid, cost effective diagnostic test to evaluate thyroid swelling. The Bethesda system for reporting thyroid cytopathology gives guidelines which remains the same while reporting the thyroid FNAC. There are six diagnostic categories of lesions: (I) Non-diagnostic/Unsatisfactory, (II) Benign, (III) Atypical follicular lesion of undetermined significance (AFLUS), (IV) Suspicious for follicular neoplasm (SFN), (V) Suspicious for malignancy (SM), (VI) Malignant.Methods: The study was carried out in Department of Pathology, Government Medical College affiliated with a Government hospital, Gujarat. It includes 150 patients, coming to the outpatient departments with a complaint of thyroid swelling from January 2017 to December 2017. The patients age ranges from 7 years to 75 years (Male-20, Female-130). The procedure was done with the patient in a supine position without a pillow. Patients were instructed not to speak or swallow during the procedure to avoid movement of the gland. The reporting was done with the current Bethesda nomenclature.Results: There were 150 cases of thyroid FNAC, 3 cases (2 %) were non-diagnostic (TBS-I), 133 cases (88.7 %) were benign (TBS-II), 6 cases (4 %) were atypical follicular lesion of undetermined significance (AFLUS) (TBS-III), 5 cases (3.4 %) were suspicious for follicular neoplasm (TBS-IV), 2 cases (1.3 %) were suspicious for malignancy (TBS-V), and 1 case (0.6 %) was malignancy (TBS-VI).Conclusions: The Bethesda system is very useful standardized system for reporting thyroid cytopathology, improving communication between cyto-pathologists and clinicians, inter-laboratory agreement, leading to more consistent management approaches.

Background: Thyroid lump is a common clinical problem in Nepal. The risk of malignancy has to be judged prior to surgery for which fine needle aspiration cytology is widely used. To bring the uniform reporting of thyroid aspirates, the Bethesda system for reporting thyroid cytopathology (TBSRTC) was introduced in 2007. This study was done to evaluate the various cytomorphological patterns of thyroid aspirate and to correlate the Bethesda system with final histopathology report.Materials and Methods: Fine needle aspiration were performed and were evaluated as per TBSRTC criteria. Fine needle aspiration cytology report were compared with biopsy specimen whenever possible.   Result: A total of 386 cases were studied. The sensitivity, specificity, positive predictive value, negative predictive value and overall accuracy of TBSRTC were 75.2%, 98.2%, 90.0%, 94.7% and 94.03% respectively. Conclusion: Use of TBSRTC in reporting thyroid cytopathology has a greater accuracy; however, benign cases need regular follow up as there are false negative cases.

Thyroid Lesions

Background: Fine Needle Aspiration Cytology (FNAC) of thyroid gland is the most common preoperative investigation for diagnosis of thyroid lesions. Though various tests like thyroid profile, ultrasonography and radionuclide scan are available, they are used as adjuvant diagnostic modalities. FNAC is simple, easy to perform, non-invasive and cost-effective procedure. Primary aim is to study the spectrum of various thyroid lesions on FNAC. Also, the study is aimed to categorise the thyroid lesions according to the Bethesda system for Reporting Thyroid Cytopathology (2017).Methods: This is a retrospective observational study carried out in the pathology department at tertiary care academic institute for a period of three years. FNAC was done in a patient with thyroid swelling by non-aspiration technique. Slides were prepared, fixed in 95% ethyl alcohol and processed with routine stains.Results: Out of 210 cases, 150 cases (71.42%) were benign lesions, 15 cases (7.14%) were Follicular neoplasm/Suspicious for follicular neoplasm, 14(6.66%) cases were reported as Atypia of undetermined significance, 13 cases (6.19%) were Unsatisfactory/Nondiagnostic, 11 cases (5.2%) were malignant and 7 cases (3.3%) were suspicious for malignancy.Conclusions: FNAC is the most effective tool for the diagnosis of thyroid lesions. The Bethesda system is used to categorise the thyroid lesions and helps in better communication between clinicians and pathologists for the best surgical and medical management. The number of benign cases were higher and the number of cases in the category of suspicious for malignancy were lower with female preponderance.
