[Oral treatment of vulvar dystrophy with an aromatic retinoid, etretinate].
Twenty patients with vulvar dystrophy (19 Lichen sclerosus, 1 Lichen ruber planus) were treated for 3 months with etretinate (Tigason) with an initial dose 0.54 mg/kg/day, maintenance dosage 0.26 mg/kg/day. All the patients had been unsuccessfully treated previously with topical oestrogen and corticosteroids. The therapeutic effect of etretinate on the subjective and objective symptoms of the disease was excellent. In most of the patients the pruritus and burning symptoms diminished within 2 weeks of treatment, and after 3 months the grade of symptoms was lower in 95% of cases. Clinically, a decrease in severity was achieved in 93% of cases among the group with severe vulvar dystrophy. The therapeutic effect of etretinate is strongly anti-inflammatory and it has a powerful effect on the epidermal tissues. According to the latest studies, etretinate also has a strong immuno-modifying effect on the epidermal cells. The secondary inflammatory changes, such as excoriatia, fissures and superinfections disappeared. In the histopathological follow-up hyperkeratosis in the stroma diminished and the inflamed cells and connective tissue normalised after 3 months of treatment. Side effects included cheilitis, dryness of mucous membranes and slight loss of hair. It must be taken into account that etretinate may cause liquid metabolism disturbances, particularly among risk factor patients (diabetes, obesity etc.). In our experience the best results to date in the treatment of vulvar dystrophy can be achieved with etretinate. Due to the teratogenic effect of etretinate, a reliable method of contraception must be used by fertile women of childbearing age.
