Согласно данным научной литературы, частота распространения рака желудка (РЖ) составляет не более чем 0,05 % среди всех случаев ЗНО ЖКТ у детей. В отечественной и зарубежной литературе описаны лишь единичные случаи РЖ у детей и подростков в возрасте от 10 до 18 лет. Клинические проявления заболевания, как и у пациентов в возрасте старше 18 лет, носят неспецифический характер – боли в эпигастрии, снижение аппетита, потеря массы тела, асцит, анемия, мелена и др. В связи с этим постановка диагноза происходит на поздних стадиях болезни и, следовательно, характеризуется неблагоприятным прогнозом. Перстневидноклеточный РЖ (ПКРЖ) является редким гистологическим подтипом аденокарциномы и встречается, как правило, у людей в возрасте от 20 до 40 лет. В данной работе представлен редкий случай развития ПКРЖ у ребенка 14 лет.</p></abstract><trans-abstract xml:lang="en"><p>Malignant neoplasms (MNP) of the gastrointestinal tract in children are extremely rare and account for 1.2 % of all MNP. According to world literature, the incidence of gastric cancer is no more than 0.05 % of all cases of MNP of the gastrointestinal tract in children. In national and foreign literature, only isolated cases of stomach cancer in children and adolescents aged 10 to 18 years are described. Clinical manifestations of the disease, as in patients over the age of 18, are non-specific – epigastric pain, loss of appetite, weight loss, ascites, anemia, melena and others. In this regard, the diagnosis occurs at the late stages of the disease and, therefore, is characterized by an unfavorable prognosis. Gastric signet ring cell carcinoma (SRCC) is an uncommon histologic subtype of adenocarcinoma and usually occurs in people aged 20 to 40 years. We would like to report an extremely rare case of SRCC in a 14-year-old child.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>перстневидноклеточный рак</kwd><kwd>рак желудка</kwd><kwd>детская онкология</kwd><kwd>эндоскопическая диагностика</kwd><kwd>эндосонографическое исследование</kwd><kwd>рентгенологическая диагностика</kwd><kwd>лечение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ring cell carcinoma</kwd><kwd>gastric cancer</kwd><kwd>pediatric oncology</kwd><kwd>endoscopic diagnostics</kwd><kwd>endosonographic examination</kwd><kwd>radiological diagnostics</kwd><kwd>treatment</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">Brecht I.B., Graf N., Schweinitz D.V., Fruhwald M.C., Bielack S.S., Schneider D.T.
