A rare lung tumor composed of contiguous foci of classical blastoma and carcinosarcoma with transitional features is described. Based on these observations and a review of the literature, we propose that pulmonary carcinosarcomas are composed of a heterogeneous population of tumors. This case supports the concept that blastomas are a distinctive subtype of carcinosarcomas. An unusual feature in the clinical presentation was the expectoration of an endobronchial portion of tumor.
描述了一种罕见的肺肿瘤，由具有过渡特征的经典母细胞瘤和癌肉瘤的相邻病灶组成。基于这些观察结果并结合文献复习，我们提出肺肉瘤样癌由异质性肿瘤群体组成。该病例支持母细胞瘤是癌肉瘤一种独特亚型的概念。临床表现中的一个不寻常特征是咳出肿瘤的支气管内部分。
