1/7. Epithelioid angiosarcoma arising in the tuberculous pyothorax: report of an autopsy case.Chronic pyothorax associated with pulmonary tuberculosis was recently proposed to be one of the predisposing factors of angiosarcoma arising in the chest wall. Separately, several authors have reported pleural angiosarcoma that has a close resemblance to mesothelioma, the latter having no apparent association with a history of pyothorax. I present a detailed pathologic description of an autopsy case of thoracic angiosarcoma arising after long-standing tuberculous pyothorax, for the purpose of better illustrating this condition. In this case, the main tumor mass was situated on the soft tissue of the chest wall outside the rib girdle. On the pleuropulmonary tissue, tumor infiltration was grossly observable as a dark patch, 2 cm in diameter, on the outer surface of the wall of the pyothorax (pleural peel). Infiltration of the tumor was found in the soft tissue just outside of the peel and in the attached rib. However, the tumor was not found in the peel itself, nor was it found in the necrotic content of the pyothorax. This case suggests that angiosarcoma associated with pyothorax is not similar to primary pleural angiosarcoma and shows the rather ordinary feature of the tumor's arising in the soft tissue.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
2/7. Tuberculous empyema necessitatis in a man infected with the human immunodeficiency virus.empyema necessitatis is a collection of inflammatory tissue that ruptures spontaneously through a weakness in the chest wail into surrounding soft tissues. Although empyema necessitatis can be caused by a number of infectious agents, mycobacteria are the most frequently implicated. empyema was a much more common complication of pulmonary tuberculosis in the preantibiotic era than it is today. We describe a 22-year-old man with human immunodeficiency virus (hiv) infection who had tuberculous empyema necessitatis and was successfully treated with surgical debridement and antibiotic therapy.- - - - - - - - - - ranking = 0.33333333333333keywords = soft (Clic here for more details about this article) |
3/7. A case of pyothorax-associated lymphoma simulating empyema necessitatis.We describe a case of a diabetic man with a 40-year history of chronic tuberculous empyema presented with fever, chest pain and bulging soft tissue of the right chest wall. CT scan revealed a huge chest wall mass showing extensive necrosis with air-bubbles and destruction of the ribs. Decortication and extirpation of the chest wall mass were performed, and histopathologic examination confirmed diffused large cell type non-Hodgkin's lymphoma.- - - - - - - - - - ranking = 0.33333333333333keywords = soft (Clic here for more details about this article) |
4/7. Pyothorax-associated angiosarcoma of the pleura with metastasis to the brain.Pleural angiosarcoma is an extremely rare, highly malignant neoplasm. Chronic tuberculous pyothorax is one of the etiological factors associated with the development of pleural angiosarcoma. This report details a case of pleural angiosarcoma in a 70-year-old woman with a history of tuberculous pyothorax. Coagulated blood surrounded by thickened pleura in the right thorax and hematoma-like multiple metastases in the brain were noted on autopsy. The pleural lesion was presumed to be the primary site. Microscopic examination revealed rudimentary channels lined by plump neoplastic cells in the coagulated blood of the pleura and the brain. These neoplastic cells stained positive for endothelial markers. A literature review of English language journals revealed this to be the first patient described in detail who developed cerebral metastasis secondary to pleural angiosarcoma.- - - - - - - - - - ranking = 0.47676223520818keywords = neoplasm (Clic here for more details about this article) |
5/7. CT demonstration of empyema necessitatis.empyema necessitatis is a collection of fluid that has, by direct extension from the pleural cavity, penetrated the thoracic wall to form a mass in the extrapleural soft tissues of the chest wall. This is a rare condition and usually is associated with tuberculous effusion but may be associated with malignancy, blastomycosis, actinomycosis, and may even follow thoracentesis.- - - - - - - - - - ranking = 0.33333333333333keywords = soft (Clic here for more details about this article) |

7/7. Malignant lymphoma arising from chronic tuberculous empyema. A case report.We report on a case of malignant lymphoma in the chest wall, associated with chronic tuberculous empyema. CT and MR imaging showed a soft-tissue mass contiguous with the empyema and invading the chest wall. MR imaging demonstrated a difference in signal intensity between the mass and the empyema. The extent of the chest-wall lymphoma was optimally delineated on fat-suppressed contrast-enhanced MR images.- - - - - - - - - - ranking = 0.33333333333333keywords = soft (Clic here for more details about this article) |
