Рецидив рака желудка чаще всего возникает в течение 5 лет после радикальной операции, при этом 60–70 % рецидивов выявляются в течение первых двух лет и 4–5 % – через 5 лет. Рецидив рака желудка чаще всего наблюдается в печени и на поверхности брюшины, но может встречаться и в нетипичных отдаленных органах. Метастазирование любой первичной опухоли в скелетные мышцы встречается редко, с частотой от 0,03 до 0,16 %. В научной литературе описано очень мало случаев изолированного метастазирования рака желудка в скелетные мышцы, т.к. изолированный гематогенный метастаз из первичной опухоли желудка, минувший портальную и легочную систему, возникает редко.</p><p>Описание клинического случая. Представлено клиническое наблюдение 64-летнего пациента, у которого через 15 лет после гастрэктомии по поводу рака желудка (без периоперативной или адъювантной химиотерапии) развился изолированный солитарный метастаз в правой прямой мышце живота. Гистопатологическое исследование биоптата, полученного методом Tru-Cut под контролем УЗИ, подтвердило наличие аденокарциномы. По данным КТ грудной клетки, брюшной полости и малого таза, а также колоноскопии первичная синхронная опухоль не обнаружена. Выполнено широкое иссечение опухоли путем резекции брюшной стенки на всю толщину, с реконструкцией дефекта полипропиленовой сеткой.</p></sec><sec><title>Заключение</title><p>Заключение. Представленный клинический случай демонстрирует, что рак желудка может метастазировать в скелетные мышцы даже через 15 лет после гастрэктомии. Другими словами, обнаружение опухолей мягких тканей, развившихся у больных через 15 лет после радикальной операции по поводу рака желудка, не исключает возможности метахронного метастазирования первичной опухоли желудка.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Recurrence of gastric carcinoma most often occurs within 5 years after radical surgery, with 60–70 % of recurrence detected within first two years and 4–5 % after 5 years. The liver and peritoneum are the most common sites of gastric cancer recurrence, but it can also spread to other distant sites. Metastases to skeletal muscle from any primary tumor are rare, with a reported incidence ranging from 0.03 to 0.16 %. Isolated hematogenous metastasis bypassing the portal and pulmonary circulation from gastric primary is a rare event. Here we report a case of a patient who developed isolated solitary metastasis in the right rectus abdominis muscle 15 years after total gastrectomy (without perioperative or adjuvant chemotherapy) for gastric carcinoma.</p></sec><sec><title>Case presentation</title><p>Case presentation. A 64-year-old patient who had undergone gastrectomy for gastric cancer 15 years earlier presented with a tumor in the right rectus abdominis muscle. Histopathological examination of the ultrasound-guided Tru-Cut biopsy confirmed the presence of adenocarcinoma. A CT scan of the chest, abdomen, and pelvis, as well as a colonoscopy, revealed no synchronous primary tumor. Wide excision of the tumor was performed, including full-thickness abdominal wall resection, with reconstruction of the defect using polypropylene mesh.</p></sec><sec><title>Conclusion</title><p>Conclusion. Our case report demonstrates that gastric cancer metastases to skeletal muscle can occur even 15 years after a curative gastrectomy. In other words, the detection of soft tissue tumors developing in patients even 15 years after gastrectomy for gastric cancer does not rule out the possibility of metachronous metastasis from the primary gastric tumor.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак желудка</kwd><kwd>гастрэктомия</kwd><kwd>солитарный метастаз рака желудка в скелетные мышцы</kwd><kwd>резекция брюшной стенки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gastric carcinoma</kwd><kwd>gastrectomy</kwd><kwd>solitary metastasis from gastric carcinoma into skeletal muscles metastasis</kwd><kwd>abdominal wall resection</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Это исследование не потребовало дополнительного финансирования</funding-statement><funding-statement xml:lang="en">This study required no funding</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">Sung H., Ferlay J., Siegel R.L., Laversanne M., Soerjomataram I., Jemal A., Bray F.
