[Pulmonary blastoma--a rare malignant lung tumor]

Pulmonary blastoma is a rare non-small-cell lung cancer. In a statistically significant proportion of cases it is combined with cystic lung disease in children. The biphasic pulmonary blastoma and the well-differentiated fetal adenocarcinoma are the most frequent manifestations of pulmonary blastoma. If metastatic disease is ruled out, surgical therapy should be guided by the principles for radical therapy of NSCLC. There are no sufficient recommendations yet for therapy of stage IIIb and IV (UICC 1997) disease.
