[Pulmonary blastoma]. / Blastoma pulmonar.

Pulmonary blastoma is a rare primary lung tumor with poor prognosis that commonly presents at a younger age than the non-small cell lung cancer. Classically they are large, symptomatic tumors with lymph nodal metastasis and carry poor prognosis. Pathological examination revealed features suggesting a biphasic tumor with mesenchymal and epithelial components. Over 200 cases have been reported so far worldwide since the first description of the tumor in 1945. Authors present a case of pulmonary blastoma with literature revision.
