BackgroundVulvar lichen sclerosus is a chronic and incurable disease that causes various unpleasant symptoms and serious consequences.ObjectiveThe purpose of the study was to assess the effectiveness of photodynamic therapy in the treatment of vulvar lichen sclerosus.MethodsParticipants in the study included 102 female patients aged 19–85 suffer from vulvar lichen sclerosus. The patients underwent photodynamic therapy (PDT). In the course of PDT the 5% 5- aminolevulinic acid was used in gel form. The affected areas were irradiated with a halogenic lamp PhotoDyn 501 (590–760nm) during a 10-min radiation treatment. The treatment was repeated weekly for 10 weeks.ResultPDT has brought about a good therapeutic effect (complete or partial clinical remission), with 87.25% improvement rate in patients suffering from lichen sclerosus. The greatest vulvoscopic response was observed in the reduction of subepithelial ecchymoses and teleangiectasia (78.95%), and the reduction of erosions and fissures (70.97%). A partial remission of lichenification with hyperkeratosis was observed in 51.61% of cases. The least response was observed in the atrophic lesions reduction (improvement in 37.36% of cases).ConclusionOur patients suffering from vulvar lichen sclerosus demonstrated positive responses to photodynamic therapy and the treatment was well tolerated. Photodynamic therapy used to treat lichen sclerosus yields excellent cosmetic results.
