Inflammatory myofibroblastic tumor (IMT) is a rare form of children neoplasm, characterized by intermediate biological behavior. In case of this, pathological diagnostics and valid tumor prognosis are difficult to perform; practitioners are not familiar enough with this pathology. Aim - to get an idea of the tumor morphological features, approaches to differential diagnosis of IMT, spreading in pediatric oncopathology, based on a review of modern literature. Material and methods. The retrospective analysis of soft tissue tumors in children operated for the period from 2007 to 2017 in Samara City Children's Clinical Hospital №1 n.a. Ivanova N.N. was performed. Among 1344 tumors, 5 cases verified as were detected IMT Results. Own clinical observations with children’s sex and age, tumor localization and speed of development, results of surgical treatment, tumor description in gross and in histological specimens, results of additional methods used in differential diagnostics from sarcomas are presented. Conclusions. Taking into account the tendency of tumor recurrence, the conclusion of the importance of morphological study of margins of tumor resection is made.</p></abstract><trans-abstract xml:lang="ru"><p>Введение. Воспалительная миофибробластическая опухоль (ВМО) - редкий вид новообразований детского возраста, характеризующийся промежуточным биологическим поведением. В связи с этим патологоанатомическая диагностика и достоверное определение прогноза ВМО затруднительны, врачи недостаточно знакомы с данной патологией. Цель - получение представления о морфологических особенностях данной опухоли, распространенности в онкопатологии детского возраста, подходах к дифференциальной диагностике ВМО, основанное на обзоре современной литературы. Материал и методы. Был проведен ретроспективный анализ патологоанатомического материала мягкотканных опухолей у детей за период 2007-2017 г., оперированных в ГБУЗ СО «Самарская городская детская клиническая больница им. Н.Н. Ивановой». Из 1344 опухолей было выявлено 5 случаев, верифицированных как ВМО. Результаты. Представлены собственные клинические наблюдения ВМО с указанием пола и возраста детей, локализации, анамнестических сведений о скорости развития опухоли и результате хирургического лечения, описанием макроскопической и гистологической картины, результатов дополнительных методов исследования для дифференциальной диагностики ВМО. Выводы. Сделано заключение о важности морфологического исследования краев резекции опухоли, учитывая склонность к рецидивам.</p></trans-abstract><kwd-group xml:lang="en"><kwd>rare tumors in children</kwd><kwd>inflammatory myofibroblastic tumor</kwd><kwd>pseudotumor</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>редкие опухоли у детей</kwd><kwd>воспалительная миофибробластическая опухоль</kwd><kwd>псевдоопухоль</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Попко А.С., Локшин К.Л., Шестакова Л.А., Ширшов В.Н.
