Epithelial hyperplastic lesions--a challenging topic in laryngology

Area of Science:

• Laryngology
• Histopathology
• Oncology

Background:

• Accurate diagnosis, treatment, and prognosis of laryngeal mucosal pathologies rely on detailed histological examination of epithelial changes.
• Epithelial hyperplastic lesions of the larynx (EHLL) are classified based on their potential progression to laryngeal cancer.
• Current classification systems face challenges due to inconsistent terminology and discrepancies between histomorphological features and biological behavior.

Purpose of the Study:

• To address the complexities in classifying and managing epithelial hyperplastic lesions of the larynx.
• To clarify the prognostic significance of surface keratosis in laryngeal pathology.
• To propose a more appropriate term for lesions with malignant potential, emphasizing clinical vigilance.

Main Methods:

• Review of histopathological criteria for epithelial hyperplastic lesions of the larynx.
• Analysis of the progression patterns from benign EHLL to carcinoma.
• Evaluation of the prognostic significance of specific histological features, including surface keratosis.

Main Results:

• Surface keratosis in laryngeal pathology does not hold independent prognostic significance.
• A proposed shift in terminology from 'precancerosis' to 'risky epithelium' is suggested.
• The term 'risky epithelium' serves as a clinical warning for close patient monitoring rather than a definitive prediction of lesion evolution.

Conclusions:

• Histological assessment of EHLL is crucial for patient management and prognosis.
• The term 'risky epithelium' is recommended to replace 'precancerosis' for lesions requiring heightened clinical attention.
• Early detection and appropriate treatment of EHLL are vital given the advancements in understanding and managing laryngeal cancer.
