Актуальность исследования обусловлена редкостью лихеноидного питириаза и ограниченным числом научных работ, посвященных описанию дерматоскопической картины заболевания. С одной стороны, изучение характерных дерматоскопических паттернов позволило бы врачу предположить диагноз, с другой – оптимизировать клиническую диагностику заболевания во всех возрастных периодах, в том числе при отсутствии возможности проведения патоморфологического исследования. Цель. Провести анализ дерматоскопических паттернов у пациентов с разными клиническими типами лихеноидного питириаза. Материалы и методы. В исследование были включены 60 пациентов (медианный возраст – Ме 13 [7; 19] лет) с диагнозом «острый лихеноидный и вариолиформный питириаз» (ОЛП) и «хронический лихеноидный питириаз» (ХЛП), находившихся под наблюдением в ГБУЗ «Московский научно-практический центр дерматовенерологии и косметологии Департамента здравоохранения г. Москвы» с 2022 по 2024 г. Все пациенты имели фототип кожи I или II. Исследование высыпаний проводилось методом дерматоскопии с 20-кратным увеличением. У пациентов с распространенным кожным процессом оценивали не менее двух элементов для учета всех возможных дерматоскопических паттернов. При описании паттернов была использована соответствующая терминология, основанная на консенсусном документе Международного общества дерматоскопии. Результаты. При ОЛП точечные сосуды визуализировались в 100,0% случаев у всех обследованных. Линейные и/или клубочковые сосуды обнаруживались у 60,0% пациентов. Частота выявления очаговых точечных сосудов и сосудов в виде клубочков была статистически значимой (р &lt; 0,01) при ОЛП, тогда как при ХЛП статистически значимой (р &lt; 0,01) была частота выявления линейных сосудов. Наличие светло-коричневых и желтоватых бесструктурных областей достоверно (р &lt; 0,001) указывает на ХЛП, в то время как мишеневидные элементы более характерны для ОЛП. Заключение. Дерматоскопия – это простой, неинвазивный и информативный диагностический метод, который при обнаружении характерных дерматоскопических признаков может быть полезен для диагностики и определения тактики ведения пациентов с лихеноидным питириазом до получения заключения гистологического исследования.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. The relevance of this study is determined by the rarity of pityriasis lichenoides and the limited number of scientific publications describing the dermatoscopic presentation of the disease. On the one hand, identification of characteristic dermatoscopic patterns would enable clinicians to establish a presumptive diagnosis; on the other hand, it would optimize clinical diagnosis across all age groups, including cases where histopathological examination is not feasible. Aim. To analyze dermatoscopic patterns in patients with different clinical subtypes of pityriasis lichenoides. Materials and methods. The study included 60 patients (median age 13 [7; 19] years) diagnosed with pityriasis lichenoides et varioliformis acuta (PLEVA) and pityriasis lichenoides chronica (PLC), who were under observation at the Moscow Scientific and Practical Center of Dermatovenereology and Cosmetology of Moscow Health Department from 2022 to 2024. All patients had Fitzpatrick skin phototype I or II. Dermatoscopic examination of the lesions was performed using 20-fold magnification. In patients with widespread skin involvement, at least two lesions were evaluated to account for all possible dermatoscopic patterns. Pattern descriptions followed the standardized terminology based on the consensus document of the International Dermoscopy Society. Results. In PLEVA, dotted vessels were visualized in 100.0% of all examined cases. Linear and/or glomerular vessels were detected in 60.0% of patients. The frequency of focal dotted vessels and glomerular vessels was statistically significant (p &lt; 0.01) in PLEVA, whereas in PLC, the frequency of linear vessels was statistically significant (p &lt; 0.01). The presence of light brown and yellowish structureless areas reliably (p &lt; 0.001) indicates PLC, while targetoid lesions are more characteristic of PLEVA. Conclusion. Dermoscopy is a simple, non-invasive, and informative diagnostic method that, upon detection of characteristic dermatoscopic features, can be useful for diagnosis and determining management strategies in patients with pityriasis lichenoides prior to obtaining histopathological confirmation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дерматоскопия</kwd><kwd>неинвазивная диагностика</kwd><kwd>питириаз лихеноидный хронический</kwd><kwd>острый лихеноидный и вариолиформный питириаз</kwd><kwd>дети</kwd><kwd>взрослые</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dermoscopy</kwd><kwd>non-invasive diagnostics</kwd><kwd>pityriasis lichenoides chronica</kwd><kwd>pityriasis lichenoides et varioliformis acuta</kwd><kwd>children</kwd><kwd>adults</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">Ankad BS, Beergouder SL.
