Lichen planus is a common chronic inflammatory disease that affects the skin and mucous membranes (especially the oral and genital mucosa) and whose aetiology is unknown. Initially, topical salves, gels or mouthwashes containing corticosteroids are used for treatment. For localized, chronic ulcerative oral lichen planus lesions (OLP), an intralesional application of corticosteroids can be used, which can sometimes be repeated two to three times at intervals of just under a month.
This case report shows that intralesional injection of triamcinolone is an effective treatment for refractory cases of OLP. Long-term and regular monitoring is required.
