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.
肉瘤样癌（SC）是一种罕见的原发性恶性肿瘤，很少发生于肺部，更罕见的是同时发生原发性肺肉瘤样癌和肺鳞状细胞癌。我们报告一例65岁中国男性患者，有3个月的咳嗽咳痰病史。诊断为低分化同步中央型原发性肺肉瘤样癌和肺鳞状细胞癌，二者比例各约50%，TNM分期为pT2aN1M0，至少为美国癌症联合委员会（AJCC）IIA期。本病例报告的目的是展示其影像学、病理学特征及治疗情况。
