Abstract:
Intrathoracic liposarcoma can occur in the lung, mediastinum, pleura, and chest wall, and tends to remain clinically silent until becoming large enough to displace adjacent structures. Treatment usually includes sufficient surgical resection followed when necessary by adjuvant chemoradiotherapy. We report a case of an uncommon presentation of a rapidly growing pleural liposarcoma, the diagnosis of which may have been obscured by coexisting thoracic trauma with suspected extrapleural hematoma.

Pleural Effusion II: Symptoms and Management
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
Clinical Manifestations:
Rapidly Varying Flow
RACE - Rapid Amplification of cDNA Ends
