We presented the family and medical history of the child complaints, orthopedic/local status, and the results of radiological methods and emphasized difficulties of nosologic identification and differential diagnosis of the bone destructive process at the stage before biopsy and surgery. Macroscopic findings during surgery were identified, and the amount of resection of the affected bone was determined. A detailed description of the results of pathological and morphological (macro- and microscopic) studies is given, which could confirm the tumor process. Late results with the absence of oncological re-occurrence (7 years) and good anatomical and functional results from orthopedic surgery are shown.</p></abstract><trans-abstract xml:lang="ru"><p>В статье отражен опыт диагностики и хирургического лечения хондромиксоидной фибромы проксимального метадиафиза бедренной кости больших размеров у ребенка первого десятилетия жизни. Подробно представлены анамнез заболевания с детализацией жалоб ребенка, ортопедический/локальный статусы, результаты лучевых методов исследования, подчеркивающие трудности нозологической идентификации и дифференциальной диагностики костно-деструктивного процесса на добиопсийном/дооперационном этапе. Запротоколированы макроскопические находки во время оперативного вмешательства, определившие объем резекции пораженного отдела кости. Дано подробное описание результатов патоморфологического (макро- и микроскопического) исследования, позволившего верифицировать опухолевый процесс. Продемонстрированы отдаленные (семилетний) безрецидивный онкологический и хороший анатомо-функциональный результаты ортопедохирургического лечения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>children</kwd><kwd>chondromyxoid fibroma</kwd><kwd>diagnosis and treatment</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>фиброма хондромиксоидная</kwd><kwd>диагностика</kwd><kwd>лечение</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Fletcher CD, Unni KK, Mertens F.
