Pulmonary endodermal tumor resembling fetal lung. Report of a case with immunohistochemical studies.
A tumor of a 12-year-old boy was studied immunohistochemically by utilizing an extensive battery of antisera against active amines and peptides. The tumor contained argyrophilic cells and resembled fetal lung. The positive immunoreaction in tumor cells for active amines and peptides further supports the probable derivation of the tumor from bronchopulmonary endocrine cells.
