ABSTRACT
BACKGROUND: We describe an unusual presentation of lichen sclerosus in a postmenarchal, virginal girl. CASE: A 14-year-old girl first presented with acute urinary retention due to labial agglutination and developed bilateral tubo-ovarian abscesses in 10 days of the conservative management period. Abscesses were treated with antibiotherapy and percutaneous drainage; simple division of the labial agglutination and vulvar biopsies were performed with a preliminary diagnosis of lichen sclerosus. Postoperative follow-up with antibiotherapy and clobetasol propionate 0.05% ointment was uneventful. SUMMARY AND CONCLUSION: Lichen sclerosus should be considered in cases of labial agglutination with atypical presentations. Finally, this case reminds us that pelvic inflammatory disease and tubo-ovarian abscess must be kept in mind even in virginal adolescents, especially in the presence of obstructive lesions of the genital tract.
