A retrospective cohort study was conducted. The authors analyzed LS incidence in girls aged 0 to 18 years, the data provided by two pediatric gynecological department, which in different years served all RB girls with gynecological pathology. A comparison of indicators recorded during the two equal and comparable time periods was carried out: the first 9 years of operation (from 1996 to 2004) at the Department of Pediatric Gynecology of the Clinical Hospital of Emergency Medical Care, Ufa and the first 9 years of operation (from 2015 to 2023) at the Gynecological Department of the Republican Children's Clinical Hospital, Ufa.</p></sec><sec><title>Results</title><p>Results. Lichen sclerosus in RB girls can be attributed to orphan disease, since its incidence rate over the past 9 years comprised 0.46 ‰. Over the 19-year follow-up (2004–2023), the accumulated LS incidence in RB girls aged 0 to 18 years increased from 0.22 to 0.46 ‰, and in Ufa – from 0.35 to 0.65 ‰.</p></sec><sec><title>Conclusion</title><p>Conclusion. In recent years, a significant increase in LS incidence in girls has been observed in the RB. Most LS patients are in the prepubertal childhood period.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель: изучить особенности эпидемиологии склерозирующего лихена (СЛ) у девочек Республики Башкортостан (РБ).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведено ретроспективное когортное исследование. По данным двух детских гинекологических отделений, которые в разные годы обслуживали всех девочек РБ с гинекологической патологией, проведен анализ заболеваемости СЛ девочек в возрасте от 0 до 18 лет. Выполнено сравнение показателей двух равных и сопоставимых периодов времени: первые 9 лет работы (с 1996 по 2004 гг.) отделения детской гинекологии ГБУЗ РБ «Клиническая больница скорой медицинской помощи» (КБСМП, Уфа) и первые 9 лет работы (с 2015 по 2023 гг.) гинекологического отделения ГБУЗ РДКБ (Уфа).</p></sec><sec><title>Результаты</title><p>Результаты. Склерозирующий лихен у девочек в РБ можно отнести к орфанному заболеванию, так как частота заболеваемости его за последние 9 лет составила 0,46 ‰. За 19 лет (с 2004 по 2023 гг.) накопленная заболеваемость СЛ девочек в РБ в возрасте от 0 до 18 лет увеличилась с 0,22 до 0,46 ‰, а в городе Уфа – с 0,35 до 0,65 ‰.</p></sec><sec><title>Заключение</title><p>Заключение. В последние годы в РБ отмечается значительный рост заболеваемости девочек СЛ. Большинство пациенток со СЛ находятся в препубертатном периоде детства.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>склерозирующий лихен вульвы</kwd><kwd>СЛ</kwd><kwd>девочки</kwd><kwd>заболеваемость</kwd><kwd>эпидемиология</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vulvar lichen sclerosus</kwd><kwd>LS</kwd><kwd>girls</kwd><kwd>morbidity</kwd><kwd>epidemiology</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">van der Meijden W.I., Boffa M.J., Ter Harmsel B. et al. 2021 European guideline for the management of vulval conditions.
