Which of the following is not classified as a white lesion?

Fordyce's granules are actually small, painless, pale yellow or white spots that occur on the mucosal tissue of the oral cavity, particularly on the inner lips and cheeks. However, they are not considered a white lesion in the same way other conditions, such as leukoplakia or lichen planus, are.

Leukoplakia, for instance, is a clinical term for a white patch that cannot be wiped off and may signify a precancerous condition, while lichen planus is an inflammatory condition that presents with lacy white striations. Smoker's keratosis, linked to long-term tobacco use, also presents as a white lesion due to keratin buildup. In contrast, Fordyce's granules are normal anatomical variations rather than pathological lesions, which is why they do not fit into the classification of white lesions.
