The pleural membrane consisting of pleural mesothelial cells and its underlying connective tissue layers play a critical role in immunological responses in both local and systemic diseases. The pleura, because of its intimate proximity to the lung, is positioned to respond to inflammatory changes in the lung parenchyma. Importantly, several systemic diseases have a predilection for expression o...
Tumors of the pleura may be primary or secondary. Primary tumors are exceedingly rare while secondary tumors are not uncommon. The most important and only primary malignancy of the pleura is the mesothelioma. In the 19th century the term, “tubercle-like lymphadenoma,”6 was used to describe this tumor. Later the name, “endothelioma,”7 was proposed for this malignancy because it was ascribed to a...
Perhaps as much because of the confusing character of the clinical phenomena, as of the rather striking appearances revealed after death, supposed primary malignant tumors of the pleurae have consistently appealed to medical writers as worthy of study and report. Further stimulus to investigation of this somewhat peculiar group has been furnished by the clearly apparent wide diversity of concep...
Lung Pulmonary nodules are commonly observed in patients with cancer as well as in patients with no known malignancy particularly in heavy smokers. Most of these nodules are small (less than 8 mm). Even in cancer patients a large proportion of these small nodules are benign [1]. The likelihood of malignancy depends on individual aspects (cancer type, grading, staging, molecular markers etc.), n...
Systemic and pulmonary diseases that affect the pleura are usually characterised by accumulation of fluid in the pleural cavity or by fibrous healing of damaged mesothelium. Some of the reactive changes in the mesothelial cells and fibroblasts concerned in these processes may closely mimic neoplasia and must be distinguished from metastatic carcinoma and malignant mesothelioma. Before we consid...
The T lymphocyte-mediated immune response to Mycobacterium tuberculosis infection in the parietal pleura of patients with tuberculous pleurisy is unknown. The aim of this study was to investigate the immune response in the parietal pleura of tuberculous pleurisy compared with nonspecific pleuritis. We have measured the numbers of inflammatory cells particularly T-cell subsets (Th1/Th2/Th17/Treg...
The cytological examination of the evacuated pleural fluid is very important in diagnosis and differential etiology effusion syndrome. Assessment effectiveness using diagnostic method a routine way was conducted within frames given study. Materials 320 patients with have been studied. In cases malignant tumors pleurisies were seen 8.1% patients, tuberculous pleurisy confirmed 26.9% cases. Pleur...
