ТЗА составляют не более 5 % от всех полипов толстой кишки. В отечественных работах данному гистологическому варианту посвящено сравнительно небольшое количество исследований, в то же время некоторые аспекты морфологической диагностики ТЗА до сих пор остаются не раскрытыми.</p><sec><title>Цель</title><p>Цель: провести клинико-морфологический анализ случаев ТЗА.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование было рассмотрено 57 случаев ТЗА, диагностированных в период с 2021 по 2023 год. В обнаруженных за данный период случаях был проведён анализ результатов гистологического и эндоскопического исследований.</p></sec><sec><title>Результаты</title><p>Результаты. Возраст пациентов варьировал от 44 до 78 лет и составил в среднем 61,7 года. Соотношение мужчин и женщин – 1:1,8. Большинство ТЗА были обнаружены в прямой (n = 28) и сигмовидной (n = 20) кишках. В восьми случаях опухоль локализовалась в нисходящем отделе и селезеночном изгибе ободочной кишки. В одном наблюдении опухоль была обнаружена в слепой кишке. Размеры полипов варьировали от 0,5 до 3,5 см. В 22 случаях в состав полипа, помимо ТЗА, входили тубуло-ворсинчатые аденомы (16 случаев) и гиперпластические полипы (6 случаев). В пяти случаях в материале ТЗА были выявлены очаги высокодифференцированной аденокарциномы.</p></sec><sec><title>Заключение</title><p>Заключение. ТЗА имеет характерные морфологические особенности с зубчатым экзофитным характером роста, цитоплазматической эозинофилией и наличием эктопических крипт. Из-за трудностей морфологической диагностики ТЗА в ряде случаев остаются недиагностированными. В то же время в виду повышенного злокачественного потенциала, ТЗА требуют особой настороженности со стороны патологов и клиницистов.</p></sec></abstract><trans-abstract xml:lang="en"><p>Traditional serrated adenomas (TSAs) are extremely rare polyps from the group of serrated polyps of the colon. TSAs is no more than 5 % of all colon polyps. A relatively small number of studies have been devoted to this histological variant, at the same time, some aspects of the morphological diagnosis of TSA still remain undisclosed. Purpose: to conduct a clinical and morphological analysis of cases of TSAs.</p><sec><title>Materials and methods</title><p>Materials and methods. The study included 57 cases of TSAs diagnosed in the period from 2021 to 2023. In the cases detected during this period, the results of histological and endoscopic studies were analyzed.</p></sec><sec><title>Results</title><p>Results. The age of patients ranged from 44 to 78 years and averaged 61.7 years. The ratio of men and women is 1:1.8. Most TSAs were found in the rectum (n = 28) and sigmoid colon (n = 20). In 8 cases, the tumor was localized in the descending part and the splenic flexure of the colon. In 1 observation, a tumor was found in the cecum. The sizes of the polyps ranged from 0.5 cm to 3.5 cm. In 22 cases, the composition of the polyp included tubulovillous adenomas (16 cases) and hyperplastic polyps (6 cases) in addition to TSAs. In 5 cases, foci of highly differentiated adenocarcinoma were detected in the TSAs material.</p></sec><sec><title>Conclusion</title><p>Conclusion. TSAs has characteristic morphological features with a serrated exophytic growth pattern, cytoplasmic eosinophilia and the presence of ectopic crypts. Due to the difficulties of morphological diagnosis, TSAs in some cases remains undiagnosed. At the same time, due to the increased malignant potential, TSAs requires special vigilance on the part of pathologists and clinicians.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>традиционная зубчатая аденома</kwd><kwd>зубчатые полипы</kwd><kwd>клинико-морфологические характеристики</kwd><kwd>малигнизация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>traditional serrated adenoma</kwd><kwd>serrated polyps</kwd><kwd>clinical and morphological characteristics</kwd><kwd>malignancy</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">Nagtegaal I.D., Odze R.D., Klimstra D., Paradis V., Rugge M., Schirmacher P.
