Question: 1 / 400

What is a characteristic feature of hairy leukoplakia?

A white, rough patch on the lateral border of the tongue

Hairy leukoplakia is characterized by a white, rough patch that typically appears on the lateral borders of the tongue. This condition is commonly associated with the Epstein-Barr virus, particularly in immunocompromised individuals, such as those with HIV/AIDS. The white patches result from an accumulation of keratin and usually indicate an opportunistic infection rather than a primary lesion.

The involvement of the lateral borders of the tongue is significant, as it helps differentiate hairy leukoplakia from other oral lesions that may appear elsewhere in the mouth. The rough texture contributes to its distinctive appearance, making it a notable feature in clinical diagnosis. Other conditions or lesions might be present in the oral cavity, but the specific characteristics of hairy leukoplakia, particularly its location and texture, are key indicators for identification.
