Primary sarcomas of the lung: report of five cases and review of the literature

Primary pulmonary sarcomas of the lung are rare tumors with a low incidence. We reviewed the literature and analyzed 5 patients retrospectively. All clinical datas and therapeutic protocols were recorded. The required surgical procedure was lobectomy in 4 patients and diagnostic broncoscopy and mediastinoscopy in one patient. At histological examination; 2 carcinosarcoma, 1 undifferentiated pleomorphic sarcoma, 1 leiomyosarcoma and 1 synovial sarcoma diagnosed. Primary sarcomas of the lung cannot be differentieted from more common tumors of the lung tumors clinically. Early diagnosis and complete surgical resection is critical for prognosis.
