The pulmonary sarcomatoid carcinoma is a rare malignant tumor, which is composed of an admixture of carcinomatous and sarcomatous components, and accounts for 0.3% of all pulmonary neoplasms. Clinicopathological features are often related to anatomical location: central endobronchial type and peripheral parenchymal type. Noninvasive diagnostic test had a low yield in detection sarcomatoid carcinoma. Metastasis to the regional lymph nodes and to distant organ is common. The prognosis is poor and the median survival is about 15 months. We report two cases of pulmonary sarcomatoid carcinoma with review of literatures.

Pulmonary carcinosarcoma(Sarcomatoid carcinoma of the lung) is a rare pulmonary malignancy, which is defined as having an admixture of both carcinomatous and sarcomatous components. Pulmonary carcinosarcoma occurs most frequently in males between 50 and 80 years of age. It predominantly affects the upper lobe and/or the principal bronchi, and is associated with a history of smoking. Here, we report a case of pulmonary carcinosarcoma with a left lobe atelectasis due to an endobronchial mass in a 56-year-old male. After a left pneumonectomy, the pathologic stage was IIb ($T_3N_0M_0$). Four months later, an abdominal mass was observed and exploratory laparotomy revealed metastases of the pulmonary carcinosarcoma to the pelvic cavity.
