The preoperative positive cytologic and histologic findings in ten cases of pulmonary blastoma are presented and compared with the results from the literature. In eight of our ten cases a preoperative diagnosis of cancer was possible, and in six of them a review of the material disclosed a biphasic feature. A pulmonary blastoma may be suggested when the preoperative microscopic specimens show immature tumor cells of tumor tissue with biphasic differentiation.
