What is the primary characteristic of geographic tongue?

1. Presence of lesions

2. Change in skin color

3. Abscess formation

4. Altered taste sensation

The correct answer is: Presence of lesions

The primary characteristic of geographic tongue is the presence of lesions. This condition, also known as benign migratory glossitis, is identified by patches on the surface of the tongue that appear smooth and often have a red, inflamed border. These lesions can change in appearance and location over time, giving the tongue a "geographic" look, which is where the name comes from. The lesions are typically painless but may be associated with a burning sensation in some individuals. While change in skin color can be associated with geographic tongue, it is not the defining characteristic. The lesions predominantly highlight the condition's presentation. Abscess formation is not typical of geographic tongue, as it does not usually involve infectious processes. Altered taste sensation may occur but is not a primary feature of the condition itself. Understanding these aspects aids in correctly identifying and discussing geographic tongue in clinical settings.
