Electron microscopy in surgical pathology: a selective review.

A E Seymour, D W Henderson

    Pathology
    |January 1, 1981
    PubMed
    Summary

    Electron microscopy (EM) reveals ultrastructural details invisible to light microscopy, aiding histomorphological diagnosis. This technique is invaluable for diagnosing neoplasms and is now a routine tool in surgical pathology.

    Area of Science:

    • Pathology
    • Histology
    • Electron Microscopy

    Background:

    • Light microscopy has limitations in visualizing fine cellular structures.
    • Certain histomorphological features are only discernible at higher magnifications.
    • Accurate diagnosis of some lesions remains challenging with conventional light microscopy.

    Purpose of the Study:

    • To highlight the utility of electron microscopy (EM) in histomorphological diagnosis.
    • To review characteristic ultrastructural features of neoplastic cells.
    • To discuss specific applications of EM in surgical pathology.

    Main Methods:

    • Review of literature on electron microscopy applications in pathology.
    • Description of ultrastructural features visible with EM.
    • Case examples illustrating diagnostic value of EM.

    Main Results:

    • EM detects nuclear/cytoplasmic contours, intercellular junctions, and intracellular components.
    • These ultrastructural findings enable specific diagnoses in ambiguous lesions.
    • EM is particularly effective for neoplasm diagnosis.

    Conclusions:

    • Electron microscopy significantly enhances diagnostic accuracy in surgical pathology.
    • It provides critical information for classifying lesions not precisely defined by light microscopy.
    • EM is an established, routine diagnostic technique, not a specialized procedure.
