Oral Hairy Leukoplakia most commonly occurs in which patient population?

• A. Immunocompromised patients (e.g., HIV, post-transplant, chronic steroids, chemotherapy)
• B. Healthy adults
• C. Children
• D. Elderly with zinc deficiency

Answer: (A)

Oral hairy leukoplakia reflects a reactivation of Epstein-Barr virus in the setting of impaired cell-mediated immunity. It tends to appear as a white, corrugated patch on the lateral tongue that cannot be rubbed off, and this pattern is most commonly seen in people with significant immunosuppression. The strongest association is with HIV infection and AIDS, where the condition is often considered AIDS-defining. Immunosuppressed patients from other causes—such as after organ transplantation or while on chronic steroids or chemotherapy—also show this lesion because their immune surveillance is reduced, allowing EBV-driven changes in the oral mucosa. In contrast, healthy adults, children, or people with zinc deficiency do not have the same strong association with EBV-driven oral lesions, so they are not the typical population in which this finding is expected. Recognizing this link is important because it should prompt consideration of underlying immunosuppression (for example, HIV testing) when the lesion is observed.
