Diagnosing malignant cells in serous effusions, often from ovarian or breast cancer, is challenging. Ancillary methods like immunocytochemistry and molecular techniques improve diagnostic accuracy for better patient management.

Area of Science:

  • Cytopathology
  • Oncology
  • Diagnostic Pathology

Context:

  • Malignant cells in serous effusions are frequently associated with advanced ovarian and breast carcinomas, carrying a poor prognosis.
  • Distinguishing malignant cells from reactive mesothelial cells in effusion specimens presents a significant diagnostic challenge.

Purpose:

  • To review and highlight ancillary diagnostic methods for identifying malignant cells in serous effusions.
  • To emphasize the role of immunocytochemistry and molecular techniques in improving diagnostic accuracy.

Summary:

  • Several ancillary techniques, including histochemistry, immunocytochemistry, flow cytometry, electron microscopy, and molecular biology, can assist in the morphological diagnosis of effusion specimens.
  • Immunocytochemistry is widely employed, utilizing epithelial and mesothelial markers. While electron microscopy is the gold standard, its availability is limited. Molecular techniques offer potential for enhanced accuracy and primary tumor origin determination.
