ABSTRACT

Selected neoplastic markers (NSE, gastrin, CEA, calcitonin, keratin) were studied in pulmonary specimens from 5 patients with bronchial carcinoid, 20--with small cell lung cancer (SCLC), and 2 with solid tumors. In patients with carcinoid and SCLC NSE and gastrin markers were found--characteristic for neuroendocrine neoplasia. The author discuss the usefulness of immunohistochemistry in differential diagnostics of pulmonary malignancy.
