Carcinosarcomas of the lung are rare biphasic tumors. This paper presents two cases of carcinosarcoma of the lung. Computed tomography of the thorax demonstrated atelectasis and a mass lesion obliterating the middle lobe bronchus and proximal part of the lower lobe bronchus in the first case. Bronchoscopic examination revealed a necrotic mass lesion obliterating the middle lobe bronchus. Computed tomography of the thorax showed left hilar mass and atelectasis of left upper lobe in the second case. Fiberoptic bronchoscopy demonstrated a mass lesion in the proximity of left upper lobe. The pathological diagnosis of bronchoscopic biopsy materials was reported as squamous cell carcinoma in both cases. Right inferior bilobectomy was performed in the first case. The tumor was composed of adenocarcinoma component and a malignant mesenchimal element. Left lobectomy superior was performed in the second case. Tumor was composed of squamous cell carcinoma, osteosarcoma and fibrosarcoma components in this case.
