Abstract

Objective To study the clinicopathologic characteristics of sarcomatoid carcinoma of the lung.Methods Clinicopathologic characteristics and immunohistochemical results of 42 cases with sarcoma- toid carcinoma of the lung were analyzed.Results Forty-two cases were pathologically proved to be spindle cell carcinoma,1 cases;giant cell carcinoma,1 case;carcinosarcoma,4 cases;pleomorphic carcinoma,36 cases.The tumors were composed of both carcinomatous and sarcomatous elements.Immunohistochemistry showed that CK was positive in 24 of 24 cases,EMA was positive in 18 of 20 cases,Vim was positive in 25 of 25 cases.Eighteen cases were survival One-year survival rate was 61.2 %,with mean survival 13.3 months. Conclusion Diagnosis of sarcomatoid carcinoma of the lung depends on pathologic and immunohistochemical results.
