A tongue lesion diagnosed as lichen planus is asymptomatic. What is the recommended treatment?

• A. Antifungal
• B. Corticosteroids
• C. Antibacterial
• D. Chlorhexidine rinse

Answer: (B)

The management of asymptomatic lichen planus, particularly when it involves the oral cavity, typically involves the use of corticosteroids. Corticosteroids are effective anti-inflammatory agents that can help to reduce inflammation and promote healing in cases of lichen planus. While some patients may not express symptoms, treatment is often pursued to prevent potential complications or worsening of the condition, especially considering that lichen planus can be linked with an increased risk of squamous cell carcinoma in oral mucosal lesions.

Corticosteroids can be administered in various forms, including topical preparations, which are particularly useful in localized lesions. They help manage the immune response that is responsible for the tissue damage seen in lichen planus. Therefore, choosing corticosteroids as a treatment option is consistent with the standard approach to managing this condition.

Other treatments listed, such as antifungals, antibacterials, or chlorhexidine rinses, do not target the underlying immune-mediated pathology of lichen planus and would not be appropriate choices for this diagnosis.
