    Histological analysis of leukoplakia revealed significant epithelial and connective tissue changes. These alterations, including hyperplasia and dysplasia, suggest a potential correlation in lesion development.

    Area of Science:

    • Oral Pathology
    • Dermatopathology
    • Oncology

    Background:

    • Leukoplakia is a potentially malignant oral disorder.
    • Understanding its histological features is crucial for risk assessment.
    • Epithelial and connective tissue changes may influence progression.

    Purpose of the Study:

    • To characterize histological alterations in leukoplakia.
    • To investigate correlations between epithelial and connective tissue changes.
    • To identify potential markers for leukoplakia progression.

    Main Methods:

    • Histological analysis of 100 leukoplakia patient samples.
    • Evaluation of epithelial changes: keratinization patterns, hyperplasia, dysplasia.
    • Assessment of connective tissue: inflammatory cell infiltration.

    Main Results:

    • Parakeratosis (39%), orthokeratosis (24%), and mixed (34%) keratinization observed.
    • Epithelial hyperplasia was the most common finding (81%).
    • Epithelial dysplasia present in 27% of cases; increased inflammation correlated with hyperplasia, parakeratosis, and dysplasia.

    Conclusions:

    • Histological findings indicate a relationship between epithelial and connective tissue alterations in leukoplakia.
    • Hyperplasia, parakeratosis, and dysplasia are associated with increased inflammation.
    • These correlations may offer insights into leukoplakia pathogenesis and progression.
