Abstract :

<p>&nbsp;Objective: The present study was conducted to evaluate the diagnostic efficacy of percutaneous fine needle aspiration cytology (FNAC) in various lung lesions, predominantly those suspicious of being malignant. Material and Method: Over a period of 20 months, percutaneous FNAC was performed in sixty patients presenting with respiratory symptoms with localized lung lesions clinically, which were confirmed radiologically. Results: Male preponderance was observed in this study with M: F ratio of 5.67:1. The most common lesion was Primary epithelial lung malignancy found in this study which constituted 78.9% of the lesions. Among malignant lesions, adenocarcinoma was the most common (44%) followed by squamous cell carcinoma (31.1%).The cytological yield of FNAC was 95.0%. Material in three cases was inadequate for interpretation. In females most common lung malignancy was adenocarcinoma. &nbsp;In Smokers commonest lung malignancy was poorly differentiated large cell carcinoma followed by small cell and squamous cell carcinoma while least common was adenocarcinoma. Sensitivity for diagnosing small cell and non-small carcinoma was 100% and 89.5% respectively. Specificity was 100% for each. Conclusion: Percutaneous transthoracic FNAC is a quite safe, simple and reliable procedure in the diagnosis of lung lesions with a high degree of accuracy, sensitivity and specificity. FNAC should be used frequently to shorten the diagnostic interval and prompt therapy for persistent lung lesions.&nbsp;</p>
