What is the appropriate treatment for asymptomatic lichen planus present on the tongue?

In the case of asymptomatic lichen planus on the tongue, the appropriate treatment involves the use of corticosteroids. Lichen planus is a chronic inflammatory condition that can affect the skin and mucous membranes, including the oral cavity. Although the lesions may be asymptomatic, corticosteroids are often used as they help reduce inflammation, control any potential progression of the condition, and mitigate the risk of secondary complications.

Corticosteroids can be particularly effective because they act by suppressing the immune response that contributes to the inflammatory process in lichen planus. This is important, especially if there is a potential for the condition to become symptomatic or lead to discomfort.

In contrast, observation and no treatment could be applicable in cases where the condition truly remains asymptomatic and does not interfere with the patient's quality of life. However, in many instances, a proactive approach with corticosteroids is preferred due to the unpredictability of lichen planus.

Antibiotics are inappropriate for treating lichen planus, as this condition is not caused by a bacterial infection. Similarly, topical antihistamines, which might be used for allergic conditions or itching, do not address the underlying inflammation associated with lichen planus and therefore would not be a suitable treatment choice in
