Abstract:
Malignant mesenchymomas are rare soft tissue tumors of mesenchymal origin. We report a case of pleural localization with liposarcomatous, leiomyosarcomatous and osteocartilaginous elements. The treatment associated surgical resection, chemotherapy and radiotherapy. Sixteen months after the diagnosis a metastatic retroperitoneal sarcoma with osteosarcomatous differentiation appeared without any sign of thoracic recurrence. A surgical resection was performed, but a rapid retroperitoneal recurrence led to death.

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.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
