The localization of CMN in aesthetically significant areas causes a decline in child self-esteem and causes concern for his parents. Surgical excision of skin areas with CMN is associated with an increased risk of cosmetic side effects and is often followed by long-term stress conditions after the invasive intervention.</p> <p><bold>Aim of the study.</bold> To evaluate the efficacy of the CMN removal in infants, children and adolescents with the dual-wavelengths copper vapor laser (CVL) radiation.</p> <p><bold>Patients and Methods.</bold> Medium-sized (up to 9 cm) single CMN was treated in nine fair-skinned patients: seven girls and two boys, aged from 2 months to 16 years. The procedures were carried out at an average CVL power of 0.6—1.0 W, with a power ratio of 3:2 at 511 nm and 578 nm wavelengths, and an exposure time of 0.2—0.3 s. Light spot diameter — 1 mm. The treatment was carried out during 2—10 sessions with an interval of 1—2 months between sessions.</p> <p><bold>Results.</bold> In children and adolescents, the treatment of CMN with CVL dual-wavelengths radiation made it possible to achieve significant clarification of the involved area without hypertrophic scars. The duration of the healing of the irradiated area lasted 2—3 weeks. Side effects were manifested with subtle skin atrophy.</p> <p><bold>Conclusion.</bold> The high efficacy of CVL removal of medium-sized CMN in infants and children using the dual-wavelengths CVL radiation without pronounced side effects allows introducing such an approach in the clinical practice of pediatric dermatologists and cosmetologists.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Абстракт.</bold> Врожденные меланоцитарные невусы (ВМН) выявляются при рождении или вскоре после рождения у 1% новорожденных. Локализация ВМН в эстетически значимых зонах становится причиной снижения самооценки ребенка и вызывает беспокойство его родителей. Хирургическое иссечение участков кожи с ВМН связано с повышенным риском косметических побочных эффектов и нередко приводит к развитию длительных стрессовых состояний у детей после оперативного лечения.</p> <p><bold>Цель исследования.</bold> Оценить эффективность лечения ВМН у детей и подростков двухволновым излучением лазера на парах меди (ЛПМ).</p> <p><bold>Методы.</bold> Лечение ВМН среднего размера (до 9 см) было проведено у девяти светлокожих пациентов: у семи девочек и двух мальчиков, в возрасте от 2 месяцев до 16 лет. Процедуры проводили при средней мощности ЛПМ 0,6—1,0 Вт, при соотношении мощности излучений 3:2 на длинах волн 511 нм и 578 нм, экспозиции — 0,2—0,3 с. Диаметр светового пятна — 1 мм. Лечение проводилось за 2—10 сеансов с интервалом 1—2 месяца между сеансами.</p> <p><bold>Результаты.</bold> У детей и подростков лечение ВМН двухволновым излучением ЛПМ позволило добиться существенного осветления в области патологического очага, без формирования гипертрофических рубцов. Продолжительность заживления кожи в области лазерного воздействия составила 2—3 недели. Побочные эффекты были выражены малозаметной атрофией кожи.</p> <p><bold>Вывод.</bold> Высокая эффективность лазерного лечения малых ВМН в эстетически значимых зонах у детей с помощью двухволнового излучения лазера на парах меди при отсутствии выраженных побочных эффектов в виде рубцов или поствоспалительной гиперпигментации позволяет использовать этот метод в клинической практике детских дерматологов и косметологов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>copper vapor laser</kwd><kwd>pigmented skin defects</kwd><kwd>congenital melanocytic nevi</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>лазер на парах меди</kwd><kwd>лечение пигментных дефектов кожи</kwd><kwd>врожденные меланоцитарные невусы</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Sandsmark M., Eskeland G., Ogaard A.R., Abyholm F., Clausen O.P.
