<p><strong>Background: </strong>Palpable neck swelling is a common clinical manifestation in otolaryngology. Rapid, inexpensive and simple method of examination for the diagnosis of such superficial masses is fine needle aspiration cytology (FNAC). Objectives were to evaluate the usage of fine needle aspiration cytology as a first-line tool for diagnosis, accuracy compared with histopathology.</p><p><strong>Method</strong>: A hospital based prospective cross sectional was conducted by taking 65 patients with neck swelling presentation thyroid swelling were highest in number followed by lymph node and salivary, in which female were 43 (66.15%) and male were 22 (33.85%), the age group ranged from 6 to 75 years in ear, nose, throat (ENT) OPD of Manipal teaching hospital between 15<sup>th </sup>November 2015 to 15<sup>th</sup> May 2017. FNAC along with histopathological examination (HPE) were done and compared. For data analysis SPSS 20 version was used. The sensitivity, specificity and accuracy rates were calculated. The Cohen’s Kappa statistical test was employed.</p><p><strong>Results</strong><strong>: </strong>The overall sensitivity and specificity of FNAC was 90.76% and 98.075% respectively in determining the various pathologies. The diagnostic accuracy of FNAC in comparison to histopathology was 92.25%. This study showed almost perfect correlation (measure of agreement) between FNAC and final histopathology diagnosis of neck swellings from Cohen’s Kappa test.</p><p><strong>Conclusions: </strong>FNAC is a safe, simple and rapid method with a high sensitivity and specificity that can be done in diagnosing wide range of neck swellings.</p>

The present study aimed to compare the diagnostic accuracy between conventional smear (CS) and liquid-based preparation (LBP) in endoscopic ultrasonography-fine needle aspiration cytology (EUS-FNAC) of pancreatic lesions. Using 31 eligible studies, the diagnostic accuracy of cytologic examination in CS and LBP was evaluated through a conventional meta-analysis and diagnostic test accuracy review. Overall concordance rates were 82.8% (95% confidence interval [CI], 79.8–85.5%) and 94.0% (95% CI, 84.4–97.8%) in CS and LBP, respectively. CS with rapid on-site evaluation (ROSE) showed a higher concordance rate than CS without ROSE. In CS, the pooled sensitivity and specificity were 89.8% (95% CI, 85.2–93.1%) and 95.0% (95% CI, 90.0–97.6%), respectively. The diagnostic odds ratio (OR) and area under curve (AUC) of the summary receiver operating characteristic (SROC) curve were 90.32 (95% CI, 43.85–147.11) and 0.945, respectively. In LBP, the pooled sensitivity and specificity were 80.9% (95% CI, 69.7–88.7%) and 99.9% (95% CI, 1.5–100.0%), respectively. The diagnostic OR and AUC of the SROC curve were 57.21 (95% CI, 23.61–138.64) and 0.939, respectively. Higher concordance rates were found in CS with ROSE and LBP in EUS-FNAC of pancreatic lesions. Regardless of the cytologic preparation method, EUS-FNAC is a useful and accurate diagnostic tool for pancreatic lesions.

Background: A wide variety of benign and malignant tumours originate in the salivary glands and insufficient tumour cells make their diagnosis difficult in some patients. The aim of this study was to evaluate the efficacy of fine-needle aspiration cytology in the diagnosis of salivary gland lesions and to correlate cytological findings with histopathology. Materials and Methods: This was a prospective study done from September 2002 to May 2004. Fine needle aspiration cytology was performed in 58 patients with clinically significant salivary gland masses. Results: Fine needle aspiration cytology categorized 67.24% of the salivary gland lesions as neoplastic and 32.76% as non-neoplastic lesions. Amongst the neoplastic lesions, 76.9% were benign and 23.1% were malignant cases. Histopathological examination revealed that 81.05% of the cases were benign and 18.95% were malignant. Fine needle aspiration cytology had a sensitivity, specificity and diagnostic accuracy of 81.82%, 100% and 96.55%, respectively. The positive predictive value and negative predictive value was 100% and 95.9%, respectively. Conclusion: Fine needle aspiration of the salivary gland is a safe and reliable technique in the primary diagnosis of salivary gland lesions. Although, limitations are encountered while predicting specific lesions on cytology, especially when dealing with cystic and some malignant lesions, this study has shown that fine needle aspiration cytology has a high sensitivity, specificity and diagnostic accuracy in diagnosing salivary gland lesions.

Multiparametric Ultrasound

Aims: To evaluate the pre-surgical diagnostic value of Multiparametric Ultrasound (MPUS) and Fine Needle Aspiration Cytology (FNAC) in differentiating parotid gland tumors, comparing the results with histology. Materials and methods:The study enrolled 84 patients with parotid gland lesions surgically treated in a single tertiary center and evaluated by MPUS. Each patient underwent FNAC. Histological examination was considered the gold standard. Results: Histology identified 62 benign tumors and 22 malignancies. In the differential diagnosis between malignant and benign lesions, B-mode Ultrasound (US), Color-Doppler US, Contrast-Enhanced US (CEUS), Elastography (USE) and FNAC showed the following values of sensitivity: 82%, 81%, 86%, 77%, 73% respectively; specificity: 97%, 61%, 95%, 71%, 97% respectively; PPV: 90%, 43%, 86%, 50%, 89% respectively; NPV: 93%, 90%, 95%, 88%, 91% respectively; and accuracy: 89%, 71%, 90%, 78%, 84% re-spectively. Conclusions: CEUS proved to be a valid and accurate method for identifying malignant tumors of parotid gland; the combination of B-mode US with CEUS showed similar diagnostic accuracy, but better sensitivity than CEUS taken alone. USE did not improve the diagnostic performance of the B-mode US, alone or in association with CEUS; however, it revealed the highest diagnostic accuracy in the differentiation between benign lesions. FNAC demonstrated lower values in comparison with CEUS and with USE. Therefore, according to our study, MPUS could be proposed as a valid alternative to FNAC.

Thyroid Lesions

More than 50% of the world’s population has at least a thyroid nodule. Detail clinical examination and radiology may help in diagnosing thyroid lesions but the management depends upon the cytopathological diagnosis. Optimum use of fine needle aspiration cytology (FNAC) and better understanding of cytomorphological characteristic of thyroid lesions by using Bethesda system, triaging of patients who are to be treated medically or surgically is more accurate. The objective of this present study is cytopathological evaluation of thyroid lesions based on Bethesda System in patients attending Birat Medical College and Teaching Hospital. The objective was also to correlate the cytological findings with histopathological findings where ever possible. A total of 104 patients with thyroid lesions underwent fine needle aspiration cytology in a period of a year (September 1, 2019 to August 31, 2020). Cytological features were evaluated and classified according to the Bethesda system. Histopathological features were evaluated and correlated wherever available. Among 104 patients with thyroid lesions 93 were female and 11 were male. Four cases turned out to be non diagnostic, 85 benign, three Atypia of undetermined significance, three Suspicious for follicular neoplasm and eight Suspicious of malignancy and one Malignant according to Bethesda system. Histopathology specimen was received in 31 patients out of whom 20 (64.5%) patients were reported as colloid nodule, two follicular adenoma, one Hurthle cell adenoma, six papillary carcinoma and two follicular carcinoma. Medullary carcinoma and anaplastic carcinoma were not seen in the patients evaluated. Specificity and sensitivity of fine needle aspiration cytology was 94.7% and 88.9% respectively. Thus reporting thyroid lesions FNAC with Bethesda system allow a more specific cytological diagnosis.
