Abstract
Two cases of blastomatous tumors of the respiratory tract are presented. The first is a pulmonary blastoma of an 81-year-old man, diagnosed as adenocarcinoma by cytologic examination, the cells being exfoliated from the large carcinomatous component. The patient died 1 year after manifestation of the symptoms. The second case is a tumor that developed in the nasopharynx of a 62-year-old man. This is the first reported case of a nasopharyngeal blastoma that presented a histology comparable to that seen in the pulmonary tumor. The presence of a hamartomatous benign mesenchymal component raises histogenetic considerations as to whether this was an independent part of an otherwise malignant tumor or whether it was induced by the malignant growth. Following incomplete surgical treatment and postoperative radiation, no recurrence was observed during the next 8 months.
