About half of people with cancer develop a pleural effusion when cancer grows in the pleural space it causes a malignant pleural effusion.

Malignant mesothelial cells in pleural fluid.

This has a large ddx. 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. However in cytologic specimens in which invasion per se cannot be assessed malignant mesothelioma is difficult to diagnose with certainty. Reactive mesothelial cells reactive mesothelial cells in pleural fluid reactive mesothelial cells are found when there is infection or inflammation present in a body cavity.

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.

This area is called the pleural space. Trauma with air in the pleural cavity. Mesothelial cells are observed with marked degenerative effects. Defects of sample preservation in a case of pleural mesothelioma.

Reactive pleural effusion showing mesothelial cells lymphocytes neutrophils and macrophages. This condition is a sign that the cancer has spread or metastasized to other areas of the body. A cluster of highly atypical mesothelial cells showing pleomorphic nuclei prominent nucleoli and slight nuclear molding. Negative for malignant cells.

The diagnostic significance of the cytologic study of the fluid may be attributable to the fact that the cell population present in the sediment is representative of a. Reactive mesothelial cells present in a background of abundant lymphocytes. Additional sampling should be considered within the clinical context. 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.
