Pulmonary blastoma (PB) is a relatively rare intratho-racic neoplasm that is composed of immature malignant epithelial and/or mesenchymal tissues whose features may resemble early embryological lung tissues [1,2]. They have been divided into three subgroups - classic biphasic pulmonary blastoma (BPB), well-differentiated fetal adenocarcinoma (WDFA) and pleuropulmonary blastoma (PPB) [2,3], among which BPB is the most common subtype and its prognosis is fairly poor, especially in case of accompanying local infiltration or distant metastasis. There have been several case reports about BPB with distant metastasis to brain, lung, kidney, even to pancrea. Here we reported a case of biphasic pulmonary blastoma with metastasis to adjacent rib.
