BACKGROUND Neck swellings are one of the most common presenting complaints of patients in all age groups. Aetiology of neck swelling has various causes congenital or acquired, cystic, inflammatory or neoplastic and vascular. Our aim was to study the diagnostic efficacy of fine needle aspiration cytology (FNAC) in neck swellings. METHODS A systematic search on the database of PubMed, Google Scholar and Academia for studies on diagnosing neck swellings by FNAC where histopathological diagnosis is considered gold standard was done and reviewed. The keywords used for searching were FNAC, neck swellings, diagnostic efficacy of FNAC. RESULTS Fine needle aspiration cytological study was considered as the first line investigation for patients presenting with neck swellings and its sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy has been reported. CONCLUSIONS FNAC is easy to perform with almost nil complications and excludes the need for a biopsy which is more complex with complications like infection and haemorrhage. FNAC in neck swellings should be considered as a complementary investigation for histopathological studies, but never a substitute.

AbstractBackgroundRoutine application of fine needle aspiration cytology (FNAC) has decreased unnecessary referral of thyroid nodules for surgical treatment and has also increased the cancer rates found in surgery materials. Success of thyroid FNAC depends on skilled aspiration, skilled cytological interpretation and rational analysis of cytological and clinical data. The aim of this study was to determine the diagnostic accuracy rates of thyroid FNAC results obtained in our institution.MethodsThe data from FNAC and thyroidectomy reports of patients presenting with goiter and who had been evaluated from 1st January 2014 to 1st March 2018 were used. There were 149 patients in total who had undergone thyroidectomy following FNAC. The Bethesda System for Reporting Thyroid Cytology was used in all cytological diagnoses.ResultsThe sensitivity of thyroid FNAC for malignant cases was 57.89%, specificity was 88.10%, false-positive rate was 11.90%, false-negative rate was 42.11%, positive predictive value was 52.38%, negative predictive value was 90.24% and accuracy rate was 82.52%. “Focus number” variable was detected as the factor that affected the accurate prediction of FNAC and thyroidectomy results by the pathologist.ConclusionsThis study showed that there was a moderate conformity between thyroid FNAC and thyroidectomy cyto-histopathological diagnosis in malignant cases. As two or more nodules have a negative effect on the physician’s diagnosis of malignant nodules, we think that a more sensitive approach is needed in the determination of these cases. Sampling defects may affect this non-matching.

Introduction: Fine Needle Aspiration Cytology (FNAC) and Cell Block are very commonly used initial tests for triaging thyroid lesions and play a pivotal role in deciding subsequent clinical management of thyroid nodules. In most cases, after excision, the diagnosis remains unchanged, but at times discordance does occur when benign lesions are reported on FNAC and cell blocks are found to be malignant on final histopathology and vice-versa. Aim: To assess the diagnostic efficacy of both FNAC and Cell Block technique in the evaluation of thyroid lesions by comparing their respective results with final histopathological diagnosis (after excision) in case of malignancies and clinico- radiological follow-up in benign cases. Materials and Methods: An observational hospital-based study was conducted in the Department of Pathology in a Tertiary Care Teaching Institute from 1st November, 2016 to 31st October, 2017. A total of 100 cases of thyroid masses were subjected to both FNAC and Cell Block and the diagnostic efficacy of both the techniques was assessed using MedCalc Statistical Software. Results: Mean age of the patients was 42.75±15.75 years with a range of 12-75 years. Females constituted 88% of the sample with male to female ratio of 1:7.3. 88% lesions were benign, 8% were malignant and 4% suspicious of malignancy on conventional smears in comparison to cell block which showed 90% benign, 8% malignant and 2% suspicious lesions. The validity of FNAC in terms of sensitivity, specificity, Positive Predictive Value (PPV), Negative Predictive Value (NPV) and accuracy was found to be 100%, 95.65%, 66.67%, 100.00% and 96.00% respectively, whereas for cell blocks these statistics were 100%, 97.83%, 80%, 100% and 98% respectively. Conclusion: Cell block improved the overall diagnostic accuracy of FNAC when used as an adjunct leading to 100% diagnostic yield. The results of this study also establish that FNAC and Cell blocks are sensitive, specific, and accurate as preliminary diagnostic tests for evaluation of patients with thyroid swellings. Moreover, their combined use can reduce the diagnostic errors and to improve the overall reporting efficacy. It is thus advised to perform cell block for each case of FNAC in thyroid lesions.

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.

<b><i>Objectives:</i></b> To determine the role and efficacy of fine needle aspiration cytology (FNAC) and cell block in diagnosis of jaw lesions and compare the agreement between FNAC and cell block to predict the diagnosis. <b><i>Method:</i></b> The sample comprised 51 cases, including 12 odontogenic keratocysts (OKCs), 8 ameloblastomas, 22 radicular cysts, 7 dentigerous cysts, and 1 each of intraosseous mucoepidermoid carcinoma (MEC) and adenomatoid odontogenic tumor (AOT). FNAC samples remaining after hematoxylin and eosin (H&amp;E)-stained cytosmear diagnosis were centrifuged at 3,000 rpm for 10 min. The supernatant was discarded and sediment mixed with 2–3 mL alcohol and filtered. To this, 10% formalin was added, filtered, taken for routine processing, and stained with H&amp;E. The result of FNAC smear and cell block was compared with histopathological diagnosis. <b><i>Results:</i></b> On cytological examination of the smears, 7 OKCs and 22 radicular cysts were diagnosed, whereas ameloblastomas, AOT, intraosseous MEC, and dentigerous cysts were not. This gave an agreement of 56.8% with the biopsy reports. Cell block sections stained with H&amp;E of 12 OKCs, 22 radicular cysts, 1 MEC, and 3 cases of ameloblastoma offered a diagnosis in accordance with the biopsies giving an agreement of 74.5%, while dentigerous cyst and AOT failed to do so. In comparison with FNAC, additionally 5 cases of OKC and 1 of MEC could be detected, and in ameloblastoma, out of 8 cases, only 3 yielded a concordant diagnosis through the cell block technique. <b><i>Conclusion:</i></b> In comparison with FNAC, the architectural pattern and the morphology of the cells were better preserved by the cell block technique. This substantiates that cell block could be used as an ancillary technique to aid in definitive diagnosis of head and neck swellings.

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

Background: Ovarian lesions are quite common among females of all age groups. Ovarian cancers account for 6% of female malignancy. Ultrasonography (USG) can help in proper identification and categorization of these lesions. Fine Needle Aspiration Cytology (FNAC) under USG guidance can be an effective modality for early diagnosis of ovarian masses. Aims And Objectives: To evaluate the role of USG guided FNAC over ovarian space occupying lesions (SOLs) for proper categorization into non-neoplastic, benign & malignant variants and to identify possible underlying causes of cytological misdiagnosis, if any, in comparison to histopathological diagnosis. Materials and Methods: FNAC under USG guidance were performed over one hundred and sixteen cases with radiologically proved ovarian SOLs during a period of five years. Aspirated materials were interpreted as non- neoplastic, benign or malignant lesions. Histopathological study was possible in 47 of these cases. Results: Out of 116 aspirations, non-neoplastic, benign and malignant diagnosis were given in 51, 42 & 23 cases, respectively. During histopathological correlation 41 out of 47 cases (87.2%) show exact cytohistological parity. Rest six cases with cytological misdiagnosis were discussed in detail. Conclusion: USG guided FNAC can effectively diagnose ovarian lesions in more than 87% cases. Scrutiny about failed diagnosis will help to improve accuracy in future.

ABSTRACT Fine needle aspiration cytology (FNAC) is considered as the gold standard diagnostic test for the diagnosis of thyroid nodules. It is a cost-effective procedure that provides specific diagnosis rapidly with minimal complications. It plays an important role in the determination of treatment- patients with suspected malignancy diagnosis can be subjected to surgery. On the other hand it can decrease the rate of unnecessary surgeries. Aims: The aim of this study was to evaluate and compare the correlation, accuracy of fine needle aspirational cytology (FNAC) in the diagnosis of thyroid lesions with the final histopathologic diagnosis in the surgical specimens. Materials and Methods: In our study we have performed a retrospective analysis of a case series of patients who were admitted to the Department of Endocrine, General and Oncological Surgery of Hospital of M. Kopernik in Łodź (Poland) between May 2016 and December 2017 and underwent FNAC with subsequent surgery. Cytological diagnosis was classified into six Bethesda categories. Results: On cytological examination 1070/1262 were reported as benign, 49 malignant and 143 suspicious. On histopathological examination, 956/1070 cases were confirmed as benign but there were 114 discordant cases. Among the other cases histopathology diagnosis of malignancy matched in 45/49 and 128/143 cases.The sensitivity and specificity were 60,28% and 98,05% respectively. False positive rate was 1.95% and false negative rate was 39.72%. The positive predictive value was 90.1% and negative predictive value was 89.35%. Accuracy of FNA in differentiating benign from malignant thyroid lesions was 89,46%. Conclusions: Fine needle aspiration cytology is a simple, cost-effective and popular procedure for the diagnosis of thyroid cancer. It is recommended as the first line investigation for the diagnosis of thyroid lessions.
