Pulmonary blastoma is one of the least common primary malignant tumors of the lung. There is considerable controversy as to its exact histogenesis; it is uncertain if it arises from a single cell or if it is a mixed tumor arising from two different cell lines. We report three patients with pulmonary blastomas, describing in detail their radiological, cytological, and histopathological features.
