However in cytologic specimens in which invasion per se cannot be assessed malignant mesothelioma is difficult to diagnose with certainty. Pleural fluid characteristics of 26 patients diagnosed with malignant mesothelioma over an 18 year period were reviewed and compared with those of patients with effusions due to other malignancies.

Mesothelial cells are found in variable numbers in most effusions but their presence at greater than 5 of total nucleated cells makes a diagnosis of tb less likely. Both non malignant and malignant causes of effusion can be identified by the relatively non invasive technique of pleural fluid cytology with this basis the present study on cytology of pleural fluids was taken up.
