Solitary fibrous tumor of the pleura is a rare and usually benign primary neoplasm arising from mesenchymal cells of the submesothelial tissue. We present here the case of a patient diagnosed with CD34-positive advanced malignant solitary fibrous tumor of the pleura whose disease failed to respond to combination cytotoxic chemotherapy agents, but demonstrated a prompt near-complete response to ...

Solitary fibrous tumour (SFT) of the pleura is a rare, usually benign primary tumour of the pleura. Spectrum of presentation can vary from an incidental finding on chest radiograph done for some other purpose, features of compression of surrounding structures to symptoms resulting from the tumour per se. We report a case of a female who presented with complaints of cough and chest pain in whom ...

Tight control of the volume and composition of the pleural liquid is necessary to ensure an efficient mechanical coupling between lung and chest wall. Liquid enters the pleural space through the parietal pleura down a net filtering pressure gradient. Liquid removal is provided by an absorptive pressure gradient through the visceral pleura, by lymphatic drainage through the stomas of the parieta...

Desmoid tumors are rare soft tissue tumors considered to have locally infiltrative features without distant metastasis until now. Although they are most commonly intraabdominal, very few cases have extra-abdominal locations. The origin of intrathoracic desmoid tumors is predominantly the chest wall with occasional involvement of pleura. True intrathoracic primary desmoid tumors with no involvem...

Two case histories are described of pleural and anterior mediastinal fibrosis presenting as a continuous fibrotic process with thick parietal pleural plaques extending from one pleura to the contralateral pleura through the retrosternal area, and with retroperitoneal fibrosis. Follow-up over 4 years in one case demonstrated rapid progression of disease, with pleural fibrosis preceding retroster...

A 52-year-old man was admitted to our hospital in June 2008 presenting abnormal tumor lesions along the left pleura on chest X-ray. The needle-biopsied specimen of the left pleura proved the biphasic type of malignant mesothelioma. However, he complained of acute abdominal pain 7 days after the diagnosis. Chest X-ray revealed free air below the right diaphragm. Emergency surgery revealed a 4-cm...

A 60-year-old man had noted exertional dyspnea and left anterior chest pain. A chest roentgenogram showed the presence of a giant mass and computed tomography (CT) of the chest confirmed the mass with an inhomogeneous density in the left hemithorax. A transthoracic TruCut needle biopsy of the mass showed benign fibrous tissue. The patient underwent a thoracotomy. A tumor arose from the visceral...

During an 18-year period, 501 cases of thoracic complications of amebic abscess of the liver were studied; 175 had inflammatory reactions of thoracic structures (165 with pleural effusions and pneumonitis, ten with pericardifis) and 326 ruptured through the diaphragm (175 into the airways, 106 into the pleural cavity, 5 into the pericardium, 39 into the airways and pleura, and 1 into the pleura...

The mesothelial surface of the visceral pleura of the Wistar rat was viewed at high resolution by scanning electron microscopy (SEM). The pleural surface showed exquisite linear arrangements made up of bulging mesothelial cells. They were organized in irregular circles that often presented anastomotic junctures. This arrangement of pleural mesothelial cells mimics the organization of subpleural...
