[Blastoma of the lung--a rare malignancy. Case report]

Pulmonary blastoma--so called because of its histological resemblance to fetal lung--is a rare malignant neoplasm, which tends to relapse locally and metastasize mainly in the first years, has a poor 5-year prognosis, and shows a potential radio-chemosensitivity. We report our findings and therapeutic approach in a case of a 64-year-old male.
