We report a case of pulmonary carcinosarcoma. Surgery is required for this rare mixed type, biphasic tumor. It is generally considered to be a malignant formation issuing from a single cell line but with a two-way differentiation into epithelial and conjunctive components. There is a differentiation continuum between spindle-cell carcinomas (also called monophasic sarcomatoid carcinoma) and carcinosarcoma (or biphasic sarcomatoid carcinoma) leading to debate concerning the immunohistochemical and ultrastructural features.
我们报告一例肺肉瘤样癌。对于这种罕见的混合型双相肿瘤需要进行手术治疗。它通常被认为是源自单一细胞系的恶性肿瘤，但是具有向上皮和结缔组织成分双向分化的特性。在梭形细胞癌（也称为单相肉瘤样癌）和肉瘤样癌（或双相肉瘤样癌）之间存在分化连续体，这引发了关于免疫组织化学和超微结构特征的争论。
