What is a common manifestation of benign migratory glossitis or geographic tongue?

Benign migratory glossitis, also known as geographic tongue, typically presents with loss of filiform papillae in irregularly outlined patches on the dorsal surface of the tongue. This condition is characterized by these smooth red areas, often bordered by white or yellowish lines. The atrophy of the filiform papillae gives these regions a distinctive appearance, which is a hallmark of this benign condition.

The loss of papillae is significant as it results in the characteristic smooth patches that can change locations and appear to "migrate," hence the name. They can also cause some discomfort or sensitivity to certain foods or spices but are generally considered harmless.

Other options present different features. Irregularly outlined areas of hyperkeratosis indicate a different type of tongue lesion, which is not typical of benign migratory glossitis. An irregularly outlined erythematous area of hypertrophic fungiform would suggest hypertrophy occurring in a different context, while furrows on the dorsal surface might refer to another condition such as tongue fissuring but not typically geographic tongue.
