A 24-year-old patient was revealed a 44 × 25 × 50 mm volumetric formation of the left side of the tongue spreading to the contralateral side and bottom of the oral cavity. The patient denied injuries or chronic autoimmune diseases. Additional studies did not reveal failure of other organs or systems. Histological conclusion: malignant spindle-polymorphic cell neoplasm with myxomatosis, perineal growth, muscle fiber infiltration and their death. An immunohistochemistry revealed expression of vimentin, CD34, S100; Ki-67 – 30 % in tumor cells. He was diagnosed with T3N0M0 fibrosarcoma of the tongue. Subtotal resection of the tongue with simultaneous microsurgical plasty via re-activated radiation autograft was performed. According to morphological study of the removed tissues, he was finally diagnosed with an aggressive inflammatory myofibroblastic tumor of the tongue. Observation period at the time of writing was 15 months. The patient eats solid food, sound pronunciation is restored in full. There are no signs of relapse or metastasis.<bold>Conclusion</bold>. Diagnostics of an inflammatory myofibroblastic tumor of the oral cavity is complex and depends on clinical and morphological features of a particular tumor. We need reliable criteria to differentiate aggressive forms of inflammatory myofibroblastic tumor of the tongue from non-aggressive ones to choose treatment. The main difficulties arise in determining the resection volume and predicting relapse or metastasis.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель работы</bold> – представить редкий клинический случай агрессивного варианта миофибробластической опухоли языка. <bold>Клиническое наблюдение</bold>. У пациента 24 лет выявлено объемное образование левой половины языка размерами 44 × 25 × 50 мм с распространением на контралатеральную сторону и дно полости рта. Пациент отрицал травмы или хронические заболевания аутоиммунной природы. Дополнительные исследования не выявили поражения других органов и систем. Гистологическое заключение: злокачественное веретено-полиморфно-клеточное новообразование с участками миксоматоза, перинеальным ростом, инфильтрацией мышечных волокон и их гибелью. При иммуногистохимическом исследовании в клетках опухоли обнаружили экспрессию виментина, CD34, S100; Ki-67 – 30 %. Был установлен клинический диагноз фибросаркомы языка Т3N0M0. Выполнена субтотальная резекция языка с одномоментной микрохирургической пластикой реиннервированным лучевым аутотрансплантатом. По результатам морфологического исследования удаленных тканей поставлен заключительный диагноз агрессивной воспалительной миофибробластической опухоли языка. Период наблюдения на момент написания статьи составил 15 мес. Пациент питается твердой пищей, функция звукопроизношения восстановлена в полном объеме. Признаки рецидива и метастазирования отсутствуют.<bold>Заключение</bold>. Диагностика воспалительной миофибробластической опухоли полости рта сложна и зависит от клинико-морфологических особенностей конкретной опухоли. Установление надежных критериев дифференцирования агрессивных и неагрессивных форм воспалительной миофибробластической опухоли языка необходимо для выбора метода лечения. Основные трудности возникают при определении объема резекции и прогнозировании рецидива или метастазирования.</p></trans-abstract><kwd-group xml:lang="en"><kwd>inflammatory myofibroblastic tumor</kwd><kwd>ALK</kwd><kwd>oral cavity</kwd><kwd>tumor of the tongue</kwd><kwd>soft tissue neoplasia</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>воспалительная миофибробластическая опухоль</kwd><kwd>ALK</kwd><kwd>полость рта</kwd><kwd>опухоль языка</kwd><kwd>неоплазии мягких тканей</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">Мaskin S.S., Karsanov A.M.
