Материалы и методы. Был проведён ретроспективный анализ и пересмотрены колонобиоптаты у 257 пациентов с воспалительными заболеваниями кишечника. Пациенты проходили лечение в клиниках Сеченовского университета в период с 2018 по 2023 годы. Возраст пациентов варьировал от 19 до 63 лет. Во всех случаях диагноз был установлен на основании комплекса клинико-лабораторных и инструментальных методов диагностики. У всех пациентов при проведении колоноскопии были получены множественные биоптаты. Обработка материала биопсий проводилась по общепринятой методике. Результаты. В ходе проведённого анализа нетрадиционная дисплазия была диагностирована у 5 пациентов, что составило 1,95% случаев за более чем 6-летний период. В двух случаях имела место гипермуцинозная дисплазия у пациентов 35 и 43 лет с язвенным колитом и длительностью заболевания 12 и 9 лет соответственно, у двух пациентов 40 и 30 лет была диагностирована дисплазия клеток крипт. Анамнез язвенного колита у этих пациентов составил 5 и 10 лет соответственно. У одной пациентки 51 года, страдавшей болезнью Крона более 15 лет, в восходящей кишке была диагностирована дисплазия, подобная зубчатому поражению. Дополнительно была проведена объективизация диагноза дисплазии с помощью иммуногистохимического исследования с использованием антител к ТР53 (clone DO-7 Leica RTU, Германия). Позитивное окрашивание ядер опухолевых клеток свидетельствовало в пользу мутации в гене ТР53. Тотальное воспалительное поражение толстой кишки имело место в 2-х из 5-ти случаев, в одном из случаев язвенного колите имело место сочетание с первичным склерозирующим холангитом. Заключение. До появления последних классификаций дисплазии при воспалительных заболеваний кишечника нами крайне редко диагностировалась дисплазия в биоптатах от пациентов с воспалительными заболеваниями кишечника. Теперь мы понимаем, что спектр потенциальных неопластических поражений-предшественников колоректального рака у пациентов с воспалительными заболеваниями кишечника намного шире, и это понимание может гарантировать, что клинически важные, но редкие поражения не будут не диагностированы. Будущие исследования их естественного течения могут в конечном итоге определить, что некоторые поражения более важны с клинической точки зрения, чем другие.</p></abstract><trans-abstract xml:lang="en"><p>Purpose: To provide a morphological characterization of dysplasia occurring against the background of inflammatory bowel disease (IBD), considering the new classification of dysplasia. Materials and methods. A retrospective analysis was conducted, and biopsies were reviewed from 257 patients with IBD treated at Sechenov University clinics from 2018 to 2023. Patients' ages ranged from 19 to 63 years. Diagnosis was based on a combination of clinical, laboratory, and instrumental methods. Multiple biopsies were taken during colonoscopy, processed using standard metods. Results. Non-traditional dysplasia was diagnosed in 5 patients, accounting for 1.95% of cases over a 6-year period. Two cases involved hypermucinous dysplasia in patients aged 35 and 43 with ulcerative colitis, with disease durations of 12 and 9 years, respectively. crypt cell atypia/dysplasia was diagnosed in two patients aged 40 and 30, with ulcerative colitis durations of 5 and 10 years, respectively. In a 51- year-old patient with Crohn's disease for over 15 years, dysplasia resembling a dentate lesion was found in the ascending intestine. Dysplasia diagnosis was confirmed using immunohistochemical (IHC) staining with TP53 antibodies (clone DO-7 Leica RTU, Germany), showing positive staining of tumor cell nuclei, indicating TP53 gene mutation. Two out of five cases exhibited total colon involvement in inflammatory process, and one ulcerative colitis case was combined with primary sclerosing cholangitis. Conclusion. Before the appearance of the latest classifications of dysplasia in IBD, we rarely diagnosed dysplasia in biopsies from IBD patients. We now understand that the spectrum of potential neoplastic precursor lesions of colorectal cancer in IBD patients is much wider and this understanding can ensure that clinically important but rare lesions will not be undiagnosed. Future studies of their natural course may eventually determine that some lesions are more clinically important than others.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дисплазия</kwd><kwd>колоректальная карцинома</kwd><kwd>ассоциированная с колитом</kwd><kwd>р53</kwd><kwd>воспалительные заболевания кишечника</kwd><kwd>морфологическая диагностика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dysplasia</kwd><kwd>colorectal carcinoma associated with colitis</kwd><kwd>p53</kwd><kwd>inflammatory bowel disease</kwd><kwd>IBD</kwd><kwd>morphological diagnosis</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">Magro F., Langner C., Driessen A., Ensari A., Geboes K., Mantzaris G.J.
