Summary
Crushing artifacts in histology are common and can mislead surgical pathologists, especially on small biopsies. Recognizing these bluish, indistinct clusters prevents misdiagnosis and adverse clinical outcomes.
Area of Science:
- Histopathology
- Surgical Pathology
- Diagnostic Challenges
Background:
- Crushing artifacts are frequent findings in histological sections.
- These artifacts pose a significant challenge for surgical pathologists, particularly with small biopsy specimens.
- Microscopically, they manifest as unidentifiable bluish cellular clusters.
Purpose of the Study:
- To present examples of crushing artifacts.
- To highlight diagnostic clues for avoiding overinterpretation.
- To emphasize the clinical implications of misinterpreting these artifacts.
Main Methods:
- Review of reported cases of crushing artifacts.
- Presentation of personally observed examples.
- Analysis of diagnostic features to differentiate artifacts from true pathology.
Main Results:
- Demonstration of characteristic bluish, acellular clusters.
- Identification of key features to distinguish crushing artifacts from neoplastic or inflammatory processes.
- Illustrative examples showcasing potential diagnostic pitfalls.
Conclusions:
- Crushing artifacts require careful evaluation to prevent misdiagnosis.
- Awareness of diagnostic clues can mitigate overinterpretation.
- Accurate identification of artifacts is crucial for appropriate patient management and avoiding unnecessary treatments.
