Background: Localized skin lesions of the genito-anal region such as in lichen sclerosus et atrophicus or in lichen planus are a burden for many patients, and therapeutic efforts, including therapies with potentially hazardous side-effects, are often unsatisfactory. Recently, PUVA bath photochemotherapy has been proven highly effective in the treatment of various inflammatory skin diseases, including localized scleroderma. Another form of topical PUVA therapy, 8-methoxypsoralen-containing cream or gel preparations, has been proven to be as effective as PUVA bath therapy for palmoplantar dermatoses. Objective: We evaluated the clinical effects of PUVA cream photochemotherapy in patients with genital lesions of inflammatory skin diseases. Methods: Twelve patients with lichen sclerosus et atrophicus, lichen planus, vulvar eczema and pruritus vulvae were included in the study. PUVA cream therapy was performed up to 4 times a week. Results: PUVA cream photochemotherapy induced a significant clinical improvement of genital lesions in most patients, as revealed by clinical examination. Clinical improvement (reduction in size of lesions of erythema, and/or of pruritus) was achieved in most patients after 10–20 treatments and was reduced in patients that had only received 5–15 treatments. Cumulative doses ranged between 4.5 and 180 J/cm2; all patients tolerated PUVA cream phototherapy well without any side-effects. Conclusion: PUVA cream phototherapy represents a highly effective therapy that should be further investigated as an alternative treatment for patients with genital lesions of inflammatory skin diseases.
