Pulmonary carcinosarcon!as are rare malignant tumors consisting of an admixture of epithelial and mas- enchymal elements of the type ordinarily seen in malignancies of adults. Compared with all pulmonary neoplasms it occurs with a frequency of 0.3% and has a strong association with smoking. Carcinosarcomas be divided into two clinicopathologic groups based on the locution of the lung: a solid parenchymal type and a central or endobronchial lesion Noninvasive diagnostic tests have a rather low yield in detecting carcinosarcoma. The most frequent metastatic sites are hilar and mediastinal Lymph nodes. Surgical resection is both diagnostic and the initial treatment. The prognosis is poor and average postoperative survival is 9 months. We report one case of pulmonary carcinosarcoma demonstrated by immunohlstochemical staining in a 61 year old male patient with a review of literatures.
