Abstract
Primary sarcoma of the lung and/or pleural cavity is a rare finding accounting for <0.5% of all thoracic malignancies. Histologically, mesothelioma predominates in this subcategory of neoplasms; its relationship to asbestos exposure and cigarette smoking is well documented. Other tumor types include fibrosarcoma, malignant fibrous histiocytoma, angiosarcoma, leiomyosarcoma, synovial sarcoma, and Ewing sarcoma. Standard evaluation with bronchoscopy and radiographically guided biopsy are frequently nondiagnostic and require open biopsy to provide an adequate tissue sample.
