Area of Science:

  • Cytopathology
  • Electron Microscopy
  • Diagnostic Imaging

Background:

  • Scanning Electron Microscopy (SEM) offers high-resolution surface imaging.
  • Body fluid cytology is crucial for diagnosing various diseases.
  • Traditional light microscopy has limitations in visualizing fine cellular structures.

Purpose of the Study:

  • To evaluate the utility of SEM for cytopathological diagnosis of body fluid specimens.
  • To determine the feasibility and diagnostic accuracy of SEM in routine laboratory settings.
  • To explore SEM's role in differentiating challenging cell types.

Main Methods:

  • Body fluid specimens were examined using Scanning Electron Microscopy (SEM).
  • Specimens were refrigerated for up to 72 hours to assess stability.
  • Diagnostic accuracy was compared with light microscopy findings.

Main Results:

  • SEM examination is technically straightforward and can be completed within hours.
  • Refrigeration up to 72 hours did not significantly alter cell structures for SEM analysis.
  • SEM effectively distinguished between reactive mesothelial cells and adenocarcinoma, and between lymphoid cells and small cell carcinoma.

Conclusions:

  • SEM is a valuable, rapid technique for cytopathological analysis of body fluids.
  • It enhances the understanding of cellular morphology and aids in accurate diagnosis.
  • SEM can serve as a critical component of quality assurance in cytodiagnostic laboratories.
