The exfoliative cytologic description of a pulmonary blastoma is reported. The debated histogenesis of these tumors is briefly reviewed. A review of all case reports recording cytopathology findings indicates that these rare tumors yield diagnostic cells in only a minority of cases. In the present case, as in previous reports, only the epithelial component (carcinoma) was recognized prior to the histopathologic diagnosis. The stromal cells were less numerous and not as conspicuous as the epithelial cells. The diagnosis of pulmonary blastoma should be considered whenever nonsquamous carcinomatous cells plus a separate population of smaller malignant cells are seen in a pulmonary cytology specimen.
本文报道了肺母细胞瘤的脱落细胞学特征。简要回顾了这些肿瘤存在争议的组织发生学。对所有记录细胞病理学结果的病例报告进行回顾表明，这些罕见肿瘤仅在少数病例中产生可诊断的细胞。在本病例中，与既往报告一样，在组织病理学诊断之前仅识别出上皮成分（癌）。间质细胞数量较少，不如上皮细胞明显。当在肺细胞学标本中见到非鳞状癌细胞加上另一群较小的恶性细胞时，应考虑肺母细胞瘤的诊断。
