[A case of primary pleural leiomyosarcoma].
A 70-year-old man was admitted to our hospital with complaints of chest pain and exertional dyspnea. Chest radiography and computed tomography (CT) revealed right pleural effusion and pleural thickening on admission. The pleural fluid was bloody. Microbiological and cytologic examinations of the fluid were negative. The chest CT revealed progress of pleural thickening after hospitalization. A thoracoscopic pleural biopsy was performed, and the histological finding of the excised specimen was leiomyosarcoma. Because no organ of origin of the leiomyosarcoma, other than the pleura, was detected, this case was diagnosed as a primary pleural leiomyosarcoma. It is thought that leiomyosarcoma originating from the pleura is rare.
