Successful Treatment of Generalized Facial Verrucae Vulgaris with a Combination of Curettage and Photodynamic Therapy in an Adolescent: A Case Report

Verrucae vulgaris are highly contagious keratotic lesions occurring on the skin caused by human papillomavirus. Generally, verrucae vulgaris are harmless to the body, but when they occur in specific areas such as the face or soles of the feet, they can profoundly impact an individual's quality of life and necessitate therapeutic intervention. Although several pharmacological and physical topical treatments are available, the results are often unsatisfactory in terms of efficacy and cosmetic outcome. Verrucae which typically occur widely on the face are usually Verrucae Planae. When Verrucae vulgaris does occur, it usually presents as single or occasional multiple lesions, rather than covering almost the entire face. In immunocompromised situations, verruca vulgaris can exhibit rare proliferative behavior. In this report, we present a 17-year-old male adolescent who was successfully treated for generalized facial verrucae vulgaris by using a combination of curettage and photodynamic therapy (PDT). The patient's prolonged use of topical corticosteroids and tacrolimus ointment on the face for eczema over several years is believed to have led to a localized immunosuppressive state of the facial skin, which is considered a significant factor in the outbreak of verrucae vulgaris. Additionally, the patient has a history of acne and frequently scratched face. The appearance of the Koebner phenomenon following scratching is considered another potential reason. This treatment achieved complete resolution and improved the patient's pre-existing acne problem, resulting in a satisfactory cosmetic outcome without any notable adverse effects or recurrence during the follow-up period. This highlighted that pre-treatment with curettage before PDT enhanced the efficiency of verrucae vulgaris treatment and reduced the cost.
