ABSTRACT Introduction Though fine needle aspiration cytology (FNAC) for thyroid is acclaimed as a gold standard before going for intervention, there are some limitations with respect to tissue availability, technique, skill of performer, etc. So, a cross-sectional study was conducted to determine the accuracy of FNAC in diagnosis of thyroid swelling and to assess the correlation between preoperative cytopathological diagnosis and postoperative histopathological diagnosis. Materials and methods Data collected from records in the time period of 3 years, i.e., from August 2012 to August 2015, were evaluated and analyzed. Results A total number of 93 cases were included in the study of which majority were females with frequency of 84.94%, most of the incidence of thyroid swellings occur in the age group of 40 to 50 years. Overall mismatch between histopathological examination and FNAC was 43 out of 93 and of which 7 were major and 36 were minor mismatch. Sensitivity of patients having malignancy with positive FNAC is 82.35% from the study and specificity of patients with nonmalignant thyroid disease and positive cytology is 95.18%. Conclusion It was observed that FNAC is a reliable, safe, and accurate method as a first line of evaluation in thyroid swelling before the surgery. Fine needle aspiration cytology is more sensitive in detecting thyroid gland malignancy but still correlation is always necessary and therefore, histopathological analysis still remains essential for final diagnosis.

BACKGROUND Most of the thyroid swellings are non-neoplastic and with normal thyroid hormone. So, it doesn't require any surgical excision, even though the thyroid swelling is an indication for surgical excision. The present study was done to evaluate the accuracy of fine needle aspiration cytology (FNAC) for the thyroid swellings and correlate it with the histopathological findings. METHODS This is a prospective study. A total of 47 cases were studied. Fine needle aspiration cytology was done, slides were made and studied. Histopathological examination of the corresponding 47 cases was also done and correlated with FNAC findings. Sensitivity, specificity and accuracy were calculated. RESULTS Age of the patients varied from 20 - 69 yrs. Most of them were in the age group of 30 - 39 years and 50 - 59 years. The ratio of male to female was 1:4.9. Swelling of the neck was the most common presentation in most of the patients. On FNAC 33 (70.2 %) cases were diagnosed as colloid nodular goitre, 04 (8.5 %) as autoimmune thyroiditis, 08 (17.0 %) as follicular neoplasm, 01 (2.1 %) as suspicious of malignancy, 01 (2.1 %) as papillary carcinoma. On histopathological examination 25 (53.2 %) cases were diagnosed as colloid nodular goitre, 01 (2.1 %) as fibrous thyroiditis, 01 (2.1 %) as Graves’ disease, 07 (14.9 %) as Hashimoto’s’ thyroiditis, 06 (12.8 %) as follicular adenoma, 01 (2.1 %) as follicular carcinoma, 04 (8.5 %) as papillary carcinoma and 02 (4.2 %) as NIFTP (noninvasive follicular thyroid neoplasm with papillary like nuclear features). The overall sensitivity was 69.2 %, specificity was 97.0 % and accuracy was 89.3 %. CONCLUSIONS FNAC is a minimally invasive, highly accurate and cost-effective procedure. FNAC helps the clinician to diagnose malignant lesions with confidence. It has high rates of specificity and accuracy but comparatively has less sensitivity. However, it is very important for the management of patients with thyroid swelling. KEYWORDS Fine Needle Aspiration, Prospective Study, Sensitivity, Specificity, Thyroid Swelling

Background: Thyroid swelling is a common disease in India. It is very important to differentiate malignant thyroid swellings from benign swellings for definitive planning of appropriate surgery and relevant patient counselling. The present study is undertaken to analyse the pattern of thyroid disease in patients coming to Department of General Surgery and to evaluate the accuracy of thyroid FNA and its correlation with histopathological examination following thyroid surgery, thereby its role in the preoperative diagnosis of thyroid swellings.Methods: A total of 114 thyroid patients were evaluated for a period of one year. The demographic data, clinical features were documented. FNAC was done in 77 patients and results were correlated with 47post operative histopathology reports and diagnostic accuracy of preoperative Fine needle aspiration cytology (FNAC) was evaluated.Results: Age of the patients ranged from 14-70 years. Females were higher than males. Most patients presented with Multinodular goitre and most were in euthyroid state. Sensitivity of FNA was found to be 67% and Specificity was found to be 100%: Accuracy was found to be 93.6% in present study. Positive predictive value was found to be 100%. Negative predictive value (NPV) was found to be 92.7%.Conclusions: Fine needle aspiration cytology has essential role in the evaluation of thyroid patients. We wish to stress the importance of doing multiple aspirations at different sites and usage of USG guidance for representative areas of suspected pathology. The diagnostic accuracy can be improved when combined with advanced imaging techniques.

INTRODUCTION: The study is an attempt to evaluate the sensitivity, specificity, positive predictive value, negative predictive value, p Value and complications of CT guided thoracic interventions fine needle aspiration cytology and core biopsy which are used for diagnosing benign and malignant thoracic lesions. MATERIAL AND METHODS: Study included 102 Patients (87 males and 15 females) with age group ranged from 15 to 87 years.A total of 143 CT guided interventions (84 FNAC’s and 59 core biopsies) were performed in 102 patients. The tissue obtained was sent to the laboratory for histopathological and cytological analysis for a final diagnosis which would contribute to patient management. RESULTS: All( 59) core biopsies were successful in procuring adequate tissue for histopathological analysis and the yield of core biopsies was 100% .However out of 84 FNAC’s only 4 were unsuccessful in procuring adequate tissue with a failure rate of 4.8%. Post procedural biopsy complications were only three (2.1%) which were small pneumothorax. There were 75 malignant lesions and 23 benign lesions based on cytology and histopathology (4 were excluded due to inadequate sample). There was good agreement between benign and malignant lesions diagnosed on CT and that diagnosed by pathology. The most common benign and malignant lesions were granulomatous lesion and squamous cell carcinoma. CONCLUSION: Percutaneous CT guided interventions like core biopsy and fine needle aspirations cytology are simple minimal invasive procedures with good patient acceptance and low morbidity and almost negligible mortality. CT guided interventions should be performed early for diagnosis of thoracic lesions.

Cysticercosis is a systemic parasitic disease caused by the larval form of cestodeT. solium. It has a worldwide distribution and is potentially harmful with variable clinical manifestations. The patient most commonly presents with subcutaneous and muscle involvement in the form of nodular lesions. The other most commonly involved sites include eye, brain, bladder wall, and heart. Cysticercosis can be diagnosed on serology, and radiologically but confirmatory diagnosis is based on histopathological examination of the involved tissue biopsy specimen. Fine needle aspiration cytology is a useful low-cost outpatient procedure tool for preoperative diagnosis of cysticercosis and is absolutely essential for diagnosis of the parasitic lesions in a peripheral hospital, one like ours.

ABSTRACT Extramedullary noncutaneous plasmacytoma (ENP) is a myeloproliferative disorder of plasma cells that rarely affects cats. This paper describes an ENP case revealed by fine needle aspiration cytology (FNAC) of the mass in the skeletal muscle of an 8-month-old, male, mixed breed cat, which had a nodule in the left hind limb. The rapid immunoassay test confirmed the presence of feline leukemia virus (FeLV). The animal necropsy macroscopically showed the nodule came from the semimembranosus muscle. Histopathological examination ratified the cytological findings. Thus, this paper alerts to the existence of plasmacytoma located in the skeletal muscle of feline species. FNAC is a quick and efficient method for diagnosis of ENP.

Purpose Sentinel node (SN) status is the most important prognostic factor for overall survival (OS) for patients with stage I/II melanoma, and the role of the SN procedure as a staging procedure has long been established. However, a less invasive procedure, such as ultrasound (US) -guided fine-needle aspiration cytology (FNAC), would be preferred. The aim of this study was to evaluate the accuracy of US-guided FNAC and compare the results with histology after SN surgery was performed in all patients. Patients and Methods Four hundred consecutive patients who underwent lymphoscintigraphy subsequently underwent a US examination before the SN procedure. When the US examination showed a suspicious or malignant pattern, patients underwent an FNAC. Median Breslow thickness was 1.8 mm; mean follow-up was 42 months (range, 4 to 82 months). We considered the US-guided FNAC positive if either US and/or FNAC were positive. If US was suggestive of abnormality, but FNAC was negative, the US-guided FNAC was considered negative. Results US-guided FNAC identified 51 (65%) of 79 SN metastases. Specificity was 99% (317 of 321), with a positive predictive value of 93% and negative predictive value of 92%. SN-positive identification rate by US-guided FNAC increased from 40% in stage pT1a/b disease to 79% in stage pT4a/b disease. US-guided FNAC detected SN tumors more than 1.0 mm in 86% of cases, SN tumors of 0.1 to 1.0 mm in 46% of cases, and SN tumors less than 0.1 mm in 23% of cases. Estimated 5-year OS rates were 92% for patients with negative US-guided FNAC results and 51% for patients with positive results. Conclusion US-guided FNAC of SNs is highly accurate. Up to 65% of the patients with SN-positive results in our institution could have been spared an SN procedure.

Introduction: Fine needle aspiration cytology is considered as the gold standard for the diagnosis of thyroid nodules. This study aimed to evaluate and compare the accuracy of fine-needle aspiration cytology in the diagnosis of thyroid lesion by comparing it with the corresponding histopathologic diagnosis after thyroidectomy. Methods: This is a retrospective study conducted over five years at a teaching hospital in Kathmandu. Eighty-nine cases of FNAC of thyroid nodule with subsequent histopathological reports were reviewed. The corresponding reports were compared and the accuracy of FNAC diagnosis was evaluated. Results: 87% of the cases were females and the majority of cases were in the age group 41 to 50 years. Among 89 cases, 55 were reported as benign on cytology and 34 were reported as malignant. On histopathological examination, out of 55 cases diagnosed as benign on cytology, 47 cases were diagnosed as benign whereas eight cases were diagnosed as malignant. HPE of 34 cases diagnosed as malignant on cytology showed that 29 were malignant and five were benign. The false-positive rate was 9.6% and the false-negative rate was 21.6%. The sensitivity was 78.3% and specificity was 90.3%. The positive predictive value and negative predictive value were 85.2% and 85.4% respectively. The accuracy of FNAC in differentiating benign from malignant thyroid lesions was 85.3%. Conclusions: The findings of this study showed that FNAC is a sensitive method for the diagnosis of a solid thyroid lesion
