Pulmonary blastoma. Preoperative cytologic and histologic findings.
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.
