Cytology, particularly fine needle aspiration (FNA) biopsy, is now a powerful diagnostic tool. Ancillary techniques like electron microscopy (EM) and immunohistochemistry (IHC) enhance diagnostic precision for challenging cases.

Area of Science:

  • Pathology
  • Oncology
  • Diagnostic Cytology

Background:

  • Cytology has evolved from a screening method to a crucial diagnostic technique.
  • The integration of fine needle aspiration (FNA) biopsy has significantly advanced cytological diagnostics.
  • Ancillary techniques are essential for refining diagnoses in complex cases.

Purpose of the Study:

  • To highlight the utility of ancillary techniques, specifically electron microscopy (EM) and immunohistochemistry (IHC), in cytological diagnosis.
  • To demonstrate how EM and IHC can improve diagnostic accuracy when used with routine cytology.
  • To address common diagnostic challenges using a combination of cytology, EM, and IHC.

Main Methods:

  • Review of diagnostic dilemmas where cytology, EM, and IHC were applied.

  • Application of routine cytological examination (FNA, body cavity fluid cytology).
  • Integration of advanced techniques: electron microscopy (EM) and immunohistochemistry (IHC).

    • Main Results:

    • EM and IHC refine and increase the precision of diagnoses when coupled with routine cytology.
    • The study provides solutions for differentiating challenging differential diagnoses.
    • Specific diagnostic problems addressed include mesothelioma vs. adenocarcinoma, neuroendocrine neoplasms, melanoma vs. carcinoma vs. sarcoma, hepatocellular carcinoma vs. adenocarcinoma, and unknown primary adenocarcinomas.

    Conclusions:

    • Cytology, augmented by EM and IHC, is indispensable for precise diagnosis.
    • These ancillary techniques are vital for resolving complex diagnostic ambiguities in surgical pathology.
    • The combined approach offers a robust strategy for accurate cancer diagnosis and subtyping.
