На вскрытии обнаружено опухолевое образование, распространяющееся из стенки тощей кишки в область брыжейки, с метастазами в мезентериальные лимфоузлы. Диагностирована медуллярная карцинома тощей кишки с позитивной экспрессией EMA, PanCK, виментина, PDL-1, мозаичной неинтенсивной экспрессией CEA, MUC-5AC, CDX2, CD117, CA19-9, кальретинина, CD10, SATB2 и негативной реакцией на CD3, CD8, CD20, CD30, CD34, CD45, CD56, хромогранин, CK7, CK20, ALK, десмин. Индекс пролиферативной активности высокий: Ki-67 &gt; 80 %. Кроме того, при гистологическом исследовании стенки кишки была диагностирована интестинальная лимфангиэктазия, в результате которой развился синдром мальабсорбции.</p></sec><sec><title>Заключение</title><p>Заключение. Уникальность данного клинико-морфологического случая заключается в сочетании медуллярного рака тощей кишки с метастазами в мезентериальные лимфатические узлы с фоновой лимфангиэктазией кишечника, сопровождающейся развитием синдрома мальабсорбции.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim: to present a clinical and morphological observation of an extremely rare combination of medullary carcinoma of the jejunum and intestinal lymphangiectasia in a 33-year-old patient with clinical features of malabsorption syndrome over the 10 years.</p></sec><sec><title>Key points</title><p>Key points. An autopsy revealed a tumor formation spreading from the wall of the jejunum to the mesentery, with metastases to the mesenteric lymph nodes. The medullary carcinoma with positive expression of СD117, DOG1, EMA, PanCK, PDL-1, vimentin, mosaic non-intense expression of CA19-9, calretinin, CD10, CDX2, CEA, MUC-5AC, SATB2, and negative reaction to ALK, CD3, CD8, CD20, CD30, CD31, CD34, CD45, CD56, chromogranin, CK7, CK20, desmin. The proliferative index was high: Ki-67 &gt; 80 %. Moreover, during the histological examination of the intestinal wall, intestinal lymphangiectasia complicated by the malabsorption syndrome was revealed.</p></sec><sec><title>Conclusion</title><p>Conclusion. The uniqueness of this clinical and morphological case is in the combination of medullary carcinoma of the jejunum metastasized to the mesenteric lymph nodes with the underlying intestinal lymphangiectasia accompanied by the development of malabsorption syndrome.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>тонкокишечная медуллярная карцинома</kwd><kwd>медуллярная карцинома</kwd><kwd>интестинальная лимфангиэктазия</kwd><kwd>синдром мальабсорбции</kwd><kwd>иммуногистохимическое исследование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>small bowel medullary carcinoma</kwd><kwd>medullary carcinoma</kwd><kwd>intestinal lymphangiectasia</kwd><kwd>malabsorption syndrome</kwd><kwd>immunohistochemical analysis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена при финансовой поддержке Министерства науки и высшего образования Российской Федерации в рамках государственной поддержки создания и развития Научных центров мирового уровня «Цифровой биодизайн и персонализированное здравоохранение» № 075-15-2022-304.</funding-statement><funding-statement xml:lang="en">the work was carried out with financial support from the Ministry of Science and Higher Education of the Russian Federation within the framework of state support for the creation and development of world-class Scientific Centers “Digital Biodesign and Personalized Healthcare” No. 075-15-2022-304.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Gonzalez H.H., Sidhu S., Eisner T.
