Abstract:
Sarcomatoid carcinoma (SC) is a rare primary malignant tumor, which seldom occurs in the lung, let alone as synchronous primary lung sarcomatous carcinoma and lung squamous cell carcinoma. We present a case of a 65-year-old Chinese man with a three-month history of cough and expectoration. The diagnosis was a combination of poorly differentiated synchronous central type primary lung sarcomatous carcinoma and lung squamous cell carcinoma with approximately 50% proportion of each, and the TNM classification was pT2aN1M0, at least AJCC Stage IIA. The purpose of the case report is to present the imaging, pathologic features, and treatment.
