Materials and Methods: Two years prospective study was done on 360 specimens of pleural effusions and were analysed. Centrifuged smears were stained and studied with clinical correlation. Results: Out of 360, 342(95%) were non neoplastic and 18(5%) were neoplastic effusions. Commonest malignancy was Adenocarcinoma. Conclusion:Non-neoplastic lesions were common in the study.
