What is Oral Leukoplakia?

Oral leukoplakia is a clinical term defining a white plaque on oral mucosa that cannot be characterized as another defined lesion and is considered a potentially malignant disorder.

Major risk factors are tobacco (smoked and smokeless), areca nut, alcohol and possibly human papillomavirus. Lateral tongue, floor of mouth and ventral tongue lesions carry higher transformation risk.

Diagnosis requires biopsy to grade epithelial dysplasia. Proliferative verrucous leukoplakia (PVL) is a high-risk subtype with multifocal involvement and substantial malignant transformation.

Symptoms

Persistent white patch on oral mucosa

Patch cannot be wiped off

Roughness or asymptomatic surface

Mixed red and white areas (erythroleukoplakia) — higher risk

Multifocal patches (PVL pattern)

Recurrence after removal

Risk Factors

Smoking and chewing tobacco

Areca nut/betel quid use

Heavy alcohol intake

Chronic mucosal irritation (sharp teeth, ill-fitting prostheses)

Human papillomavirus infection

Older age and male sex

When to See a Doctor?

White oral patch persisting more than 2 weeks
Mixed red-white lesion or ulceration
Lesion on lateral/ventral tongue or floor of mouth
Increase in size, induration or pain
History of head and neck cancer

Treatment Methods

Cessation of tobacco, areca nut and alcohol
