    Diagnoses of skin lesions can be made quickly and accurately using unstained tissue sections and negative image patterns. This method allows for early checks on section orientation and pathology identification, improving slide quality and diagnostic speed.

    Area of Science:

    • Histopathology
    • Dermatopathology
    • Microscopy

    Background:

    • Historically, pathologists diagnosed conditions using unstained tissue sections.
    • Modern histopathology relies heavily on stained slides for diagnosis.

    Purpose of the Study:

    • To evaluate the utility of unstained paraffin-embedded skin sections for rapid and accurate dermatopathological diagnosis.
    • To explore the advantages of negative image patterns in diagnosing skin lesions.

    Main Methods:

    • Low-power scanning microscopy of fresh, wet, paraffin-embedded skin sections.
    • Utilizing negative image patterns for diagnostic assessment.

    Main Results:

    • Unstained sections allow for early checks on section orientation, completeness, and identification of pathological areas.
