What is a distinguishing feature of white sponge nevus compared to other conditions?

White sponge nevus is characterized by a distinctive feature where the lesions tend to become more prominent during adolescence. This is significant because the condition is often associated with genetic factors, specifically mutations in the keratin genes, which can become more apparent as a person goes through puberty and the changes in the body that accompany adolescence.

The lesions are typically bilateral and symmetrical, presenting as white, spongy plaques in the oral cavity, particularly in areas like the buccal mucosa (the inner lining of the cheeks). The visibility of the lesions can increase during this developmental stage, making it a key aspect in diagnosing the condition. This tendency for prominence at this age distinguishes white sponge nevus from other conditions that may also present with oral lesions but do not have this hallmark feature of becoming more apparent during adolescence.

In contrast, other features mentioned in the options do not accurately relate to white sponge nevus. For example, the lesions do not disappear with stretching, they are not associated with tobacco use, and they are not infectious. Understanding these characteristics is crucial for recognizing and differentiating white sponge nevus from other oral lesions or conditions.
