Pulmonary blastoma: cytopathologic and histopathologic findings.

A case of pulmonary blastoma has been presented with a description of the pulmonary cytology and review of the literature. Recognition of the two cell patterns of the tumor, carcinomatous and sarcomatous elements, in the cytologic specimen may lead one to the correct diagnosis of a mixed tumor. Ferruginous bodies and microliths were also associated in this case.
