Clinico-Pathological Perspectives on Potentially Malignant and Malignant Lesions of the Oral Cavity: A Comprehensive Review

Abstract

Background: Oral potentially malignant disorders (OPMDs) and oral malignancies contribute significantly to global morbidity, especially in regions with high tobacco and areca nut use. Early detection and accurate clinico-pathological assessment are crucial for improving outcomes.

Aim: To comprehensively review the epidemiology, etiopathogenesis, clinical features, histopathological characteristics, diagnostic advancements, and management approaches of OPMDs and oral malignancies.

Methods: Relevant literature on clinical presentation, pathological evaluation, molecular alterations, and diagnostic innovations in oral cavity lesions was critically examined to highlight current understanding and evolving concepts.

Results: OPMDs such as leukoplakia, erythroplakia, oral submucous fibrosis, and lichen planus show variable malignant transformation potential influenced by lifestyle habits, genetic factors, and environmental exposures. Histopathology remains the gold standard for assessing dysplasia and malignancy, while emerging techniques—such as optical imaging, cytopathological adjuncts, biomarkers, and artificial intelligence—offer promise for early detection. Effective management requires a multidisciplinary approach combining risk assessment, clinical monitoring, and timely intervention.

Conclusion: Strengthening clinico-pathological correlation, improving early detection strategies, and integrating advanced diagnostic tools are essential for reducing the burden of oral cancer. Preventive measures, public health awareness, and personalised management approaches can significantly enhance patient outcomes.
