What is the characteristic presentation of Oral Hairy Leukoplakia?

• A. Painless white plaque on lateral tongue borders or buccal mucosa that can be scraped off.
• B. Painless white plaque on lateral tongue borders or buccal mucosa that cannot be scraped off.
• C. Red, painful ulcer on the tongue.
• D. Pigmented patch on gingiva that bleeds easily

Answer: (B)

Oral Hairy Leukoplakia presents as a painless white plaque on the lateral borders of the tongue (often with a corrugated, “hairy” surface) that cannot be rubbed off with gentle scraping. This non-scrapable, white lesion is a hallmark, and it typically occurs in immunocompromised individuals, especially those with HIV/AIDS, due to EBV-driven epithelial changes. The inability to remove the lesion with scraping helps distinguish it from candidal infections, which present as white plaques that can be wiped away. In other words, the key features are a painless white plaque on the lateral tongue that cannot be scraped off, often in an immunocompromised patient. Red, painful ulcers or pigmented gingival patches do not fit this presentation.
