[Vulvovaginal complaints, dyspareunia and oral mucosa abnormalities: erosive lichen planus].

Three women, aged 46, 48 and 73 years respectively, suffered from erosive genital lichen planus. Vulvar irritation, dyspareunia and vaginal discharge are the prominent signs of this disease. Lichen planus is an inflammatory dermatosis, which can involve skin and oral and genital mucosa. Diagnosis and treatment are difficult. Prolonged local application of a corticosteroid cream, e.g. clobetasol, is usually warranted. Narrowing of the vagina and painful mucosal lesions often prevent sexual intercourse. The combination of oral and genital complaints can help in the diagnosis of lichen planus. Strict follow-up is necessary because of the possible malignant degeneration of the disease.
