Summary
Histopathology and cytopathology images can mimic infectious agents, leading to misdiagnosis. This review details these "false pathogens" and diagnostic pitfalls to improve accuracy and patient care.
Area of Science:
- Medical Mycology
- Parasitology
- Bacteriology
- Virology
- Histopathology
- Cytopathology
Background:
- Microscopic examination in histopathology and cytopathology frequently reveals structures resembling infectious agents.
- Misidentification of these non-pathogenic entities can lead to incorrect diagnoses and inappropriate, potentially toxic treatments.
Purpose of the Study:
- To review and illustrate
Main Methods:
- Morphological analysis of common false pathogens.
- Review of diagnostic pitfalls in identifying these entities.
- Discussion of contamination issues.
Main Results:
- Detailed descriptions of exogenous and endogenous agents that mimic mycotic agents, parasites, bacteria, and viruses.
- Identification of key morphological features to differentiate true pathogens from artifacts.
- Outline of common diagnostic errors and challenges.
Conclusions:
- Accurate differentiation of false pathogens from true infectious agents is crucial for appropriate patient management.
- Awareness of these mimics and diagnostic pitfalls can prevent unnecessary or harmful treatments.
- Proper sample handling and interpretation are essential to avoid contamination-related errors.
