Which statement is true regarding migratory glossitis (geographic tongue)?

Migratory glossitis, also known as geographic tongue, is characterized by the presence of irregular, smooth, red patches on the tongue that are surrounded by a whitish or yellow border. The condition tends to be benign and is often associated with other systemic conditions.

The correct choice highlights that individuals with psoriasis indeed show a higher prevalence of migratory glossitis. This connection is important because psoriasis is an autoimmune condition that affects the skin, and its associated changes can extend to the tongue, leading to variations in the normal mucosal tissue.

Additionally, there is a noted correlation between a fissured tongue and the occurrence of migratory glossitis. A fissured tongue, which presents with grooves or fissures on the dorsal surface, can coexist with geographic tongue. The two conditions may share common underlying factors such as genetics or immune dysfunction, leading to their co-occurrence.

In summary, both the relationship between psoriasis and migratory glossitis, as well as the association between a fissured tongue and migratory glossitis, supports the validity of the statements in the correct choice.
