Honey, is your son a flat wart? Verruca plana is usually a self-limiting disease. Therefore, the focus of treatment is to speed up the alleviation of symptoms and control itching.
Local corticosteroids are the first-line treatment for local lichen planus. Local corticosteroids are often used as an adjuvant therapy for systemic therapy or phototherapy.
Local corticosteroids - Although local corticosteroids are the main treatment for patients with local lichen planus, the efficacy of these drugs has not been evaluated in clinical trials. Based on the recommendation of clinical experience and the relative safety of this therapy, local corticosteroids are used as first-line treatment.
Local lichen planus of the trunk and extremities is usually treated with topical corticosteroids (e.g., 0.05% betamethasone dipropionate, 0.05% difluoroacetate) cream or ointment (twice a day). Because topical corticosteroid-induced skin atrophy is most likely to occur on the rubbed or facial skin, the use of moderate or inefficient corticosteroid cream or ointment is preferred in the treatment of lesions in these areas. Therapeutic effects should be evaluated after 2-3 weeks of treatment.
However, there is a risk of skin atrophy and this side effect should be closely observed and followed up.
Intrathermal injection of corticosteroids - topical corticosteroids for hypertrophic lesions of lichen planus may be less effective than for typical skin lesions. Clinical experience has shown that intradermal corticosteroid injection can benefit patients with hypertrophic lichen planus. Triamcinolone acetonide with a concentration of 2.5-10 mg/mL is usually given to treat the disease. The dosage should be able to make hypertrophic lesions white or at least infiltrate hypertrophic lesions. Corticosteroids should be avoided to the greatest extent from spreading to the surrounding normal skin. We limited the total dose of triamcinolone acetonide to no more than 40 mg per treatment. After 4-6 weeks, the injection can be repeated.
