Abstract:
:This article has presented information concerning the ultrastructural features and, to a lesser degree, the immunohistochemical characteristics of lung neoplasms. Electron microscopy and immunohistochemistry are useful techniques for diagnosing and understanding common and rare lung tumors. Electron microscopy is particularly helpful in accurately diagnosing undifferentiated lung tumors such as large-cell undifferentiated and small-cell undifferentiated carcinomas. Ultrastructural studies of lung tumors have also aided in overall understanding of the histogenesis of these tumors. Electron microscopy and immunohistochemistry are techniques that can be applied to tiny specimens, including those obtained via fine-needle aspiration biopsy, and to cells obtained from pleural fluid. An intelligent use of electron microscopy and immunohistochemistry aids in the diagnosis and understanding of lung neoplasms.
