Genitourinary organs are an exceedingly rare location of the Ewing’s sarcoma. There are still no widely accepted treatment protocols for such patients. We report a rare case of Ewing’s sarcoma of the ureter in a 68-year-old man who was admitted to the Cancer Research Institute, Tomsk National Research Medical Center. He was suspected of having a bladder tumor. After completing his treatment course which included surgery and adjuvant chemotherapy, the patient demonstrated no signs of local recurrence or metastasis for a long time.</p></abstract><trans-abstract xml:lang="ru"><p>Cаркома Юинга – высокоагрессивная злокачественная опухоль, часто поражающая кости скелета. Органы мочеполовой системы относятся к наиболее редким экстраоссальным локализациям саркомы Юинга. На сегодняшний день нет общепринятых рекомендаций по лечению пациентов с данной патологией. В настоящей статье представлен клинический случай диагностики и лечения саркомы Юинга мочеточника у мужчины 68 лет, который поступил в НИИ онкологии Томского национального исследовательского медицинского центра с подозрением на опухоль мочевого пузыря. После завершенного комбинированного лечения, включившего хирургию и адъювантную химиотерапию, пациент длительное время остается без признаков местного рецидива и метастазирования.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Ewing’s sarcoma</kwd><kwd>primitive neuroectodermal tumor</kwd><kwd>ureter</kwd><kwd>surgery</kwd><kwd>chemotherapy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>саркома Юинга</kwd><kwd>примитивная нейроэктодермальная опухоль</kwd><kwd>мочеточник</kwd><kwd>хирургическое лечение</kwd><kwd>химиотерапия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Hart MN, Earle KM.
