(68,69) Natatani et al (68) found mutations in exon 3 of the [beta]-catenin gene in 3 of 4 blastomas, but not in 5 carcinosarcomas with a high-grade fetal adenocarcinoma component.
The carcinoma component is most often squamous cell carcinoma, followed by adenocarcinoma, adenocarcinoma mixed with squamous cell carcinoma, and finally, large cell carcinoma, whereas the sarcoma component is most commonly rhabdomyosarcoma, followed by osteosarcoma mixed with chondrosarcoma, and osteosarcoma alone (Figure 2, E).7 The final subtype, pulmonary blastoma, is a biphasic tumor composed of a primitive epithelial component resembling well-differentiated, fetal adenocarcinoma and a primitive mesenchymal stroma that may contain rhabdomyosarcoma, osteosarcoma, or chondrosarcoma (Figure 2, F).
