Mesothelial Cells In Pleural Fluid Tuberculosis

Mesothelial cells in ascitic fluid mesothelial cells in ascitic fluid the associated tumor antigen 90k is known to possess properties similar. 625 and 1 416.

An Uncommon Cause Of Pleural Effusion European Respiratory Society

Pleural effusion may occur at any stage of active tuberculosis.

Mesothelial cells in pleural fluid tuberculosis. Eighty five samples of pleural fluid obtained from 76 patients with biopsy proven tuberculous pleurisy were examined cytologically. Numerous reactive mesothelial cells were present in only 12 of specimens examined. The suggestion that the presence of numerous often very reactive mesothelial cells in pleural aspirate makes the diagnosis of tuberculosis is unlikely confirmed mesothelial cells in pleural fluid.

1 the fluid is generally an exudate 2 characterized by a predominance of lymphocytes and a paucity or absence of mesothelial cells3 4 5 in fact it has been concluded that the presence of numerous mesothelial cells almost excludes a diagnosis of tuberculosis. Sensitivity of polymerase chain reaction to detect mycobacterium tuberculosis in pleural fluid varies from 40 to 80 percent and. We report three hiv infected patients with tuberculous pleural effusions in which mesothelial cells were found in significant numbers in the pleural fluid.

The culture of the pleural fluid grew m tuberculosis. 7 neutrophils 22 lymphocytes 60 macrophages and 10 mesothelial cells. Pleural fluid from patients with tuberculosis had cells with patterns 1 914.

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. The patient was treated with a combination of six anti tb medications and was started on an antiretroviral regimen. Both the visceral and parietal pleurae are lined with a single layer of flat mesothelial cells that have some similarity of epithelial.

In contrast the combination of histology and culture of pleural tissue obtained by pleural biopsy. 1 the pleura is a serous membrane that covers the lung parenchyma mediastinum diaphragm and rib cages and is divided into the visceral and parietal pleura. Population 1 plus cells of variable size and complexity probably corresponding to macrophages and mesothelial cells in fluid.

Tuberculous pleurisy is the most frequent extrapulmonary manifestation of tuberculosis. Pleural fluid cultures grow m tuberculosis in less than 65 of cases. This report concerns two cases of tuberculous pleural effusion in.

643 and 3 514. The scarcity of mesothelial cells is a well known characteristic of tuberculous pleural effusions. Numerous reactive mesothelial cells were present in only 12 of.

The cytology showed reactive mesothelial cells and the differential cell count was as follows. In contrast 653 of pleural fluid aspirates obtained from a control group of pati. 357 whereas most fluid secondary to cancer had cells with patterns 4 1016.

Eighty five samples of pleural fluid obtained from 76 patients with biopsy proven tuberculous pleurisy were examined cytologically. Actively dividing mesothelial cells can mimic an adenocarcinoma.
