Cutaneous lichen amyloidosis is a form of primary localized cutaneous amyloidosis. This is a rare condition with comparable incidence rates in males and females. Cutaneous amyloidosis affects the psychological state and quality of life due to its chronic course, severe subjective discomfort, and limited efficacy of existing therapeutic options. Cutaneous amyloidosis is frequently associated with chronic pruritus, the most bothersome subjective symptom that causes irritable mood and sleep disorders, as well as secondary hyperpigmentation, which enhances esthetic discomfort and psychological stress, especially in young women. The low treatment efficacy is associated with the nature of this condition and the mechanisms of amyloid deposition in the skin. Localized amyloidosis is easier to treat than generalized amyloidosis. Quinolines, dimercaprol, aromatic retinoids, topical glucocorticoids, topical calcineurin inhibitors, and other commonly prescribed drugs are not always effective. Laser dermabrasion (ablative and non-ablative) with mechanical removal or destruction of amyloid deposits in the skin is a promising therapeutic option in cutaneous amyloidosis. In this clinical case of primary cutaneous lichen amyloidosis, a CO<sub>2</sub> laser was used as additional therapy with favorable outcomes, including a reduction in skin rash and discoloration.</p> <p>Given the growing interest in laser therapy for various dermatoses, it is relevant to explore and apply selective laser photothermolysis in the treatment of cutaneous amyloidosis to transform the therapy of metabolic skin diseases.</p></abstract><trans-abstract xml:lang="ru"><p>Амилоидоз кожи ― заболевание, возникающее вследствие нарушения белкового обмена, вызванного образованием и внеклеточным отложением в коже специфического белково-полисахаридного комплекса ― амилоида. Лихеноидный амилоидоз кожи является одной из форм первичного локализованного амилоидоза кожи. Дерматоз встречается редко и одинаково поражает лиц обоего пола. Влияние кожного амилоидоза на психологический статус и качество жизни пациентов обусловлено его хроническим течением, выраженным субъективным дискомфортом и ограниченной эффективностью лечения. Кожный амилоидоз часто сопровождается хроническим зудом, который является доминирующим субъективным симптомом, вызывающим значительное беспокойство, раздражительность и нарушения сна, а также развитием вторичной гиперпигментации, что усугубляет эстетический дискомфорт и усиливает психологический стресс, особенно у молодых женщин. Причины низкой эффективности лечения связаны с природой заболевания и механизмом отложения амилоида в коже. Ограниченные формы амилоидоза в сравнении с генерализованными легче поддаются лечению и коррекции. Назначение препаратов хинолинового ряда, димеркапрола, ароматических ретиноидов, топических глюкокортикоидов, топических ингибиторов кальциневрина и других препаратов не всегда даёт желаемый результат. Перспективным методом лечения амилоидоза кожи является лазерная дермабразия (аблятивная и неаблятивная), связанная с механическим удалением или деструкцией амилоидных отложений в коже. В представленном нами клиническом случае первичного лихеноидного амилоидоза кожи в качестве дополнительного метода лечения показано применение CO<sub>2</sub>-аблятивного лазера с выраженным положительным эффектом в виде уменьшения количества высыпных элементов и пигментации.</p> <p>В связи с ростом интереса к лазерным методам терапии дерматозов различного генеза считаем важным изучение и применение селективного лазерного фототермолиза в лечении кожного амилоидоза, что, возможно, поможет разработать новый подход к терапии кожных заболеваний, связанных с нарушением обмена веществ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>lichen amyloidosis</kwd><kwd>cutaneous amyloidosis</kwd><kwd>СО2 laser</kwd><kwd>laser therapy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>амилоидный лихен</kwd><kwd>кожный амилоидоз</kwd><kwd>аблятивный СО2-лазер</kwd><kwd>лазерная терапия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Mikheev GN, Krasnoselskikh TV, Yastrebov VV, et al.
