ЗООПН с дивергентной (гетерологичной) дифференцировкой с наличием рабдоидного компонента крайне редка, составляет 5 % всех ЗООПН, которые составляет примерно 2 % всех сарком мягких тканей. Подгруппа опухолей, в которых злокачественные шванновские клетки сосуществуют со злокачественными рабдомиобластами, называется злокачественной тритон опухолью (ЗТО) [<xref ref-type="bibr" rid="cit10">10</xref>]. В большинстве опубликованных клинических наблюдениях, малигнизация тритон-опухоли встречается в голове, шее, конечностях и туловище [<xref ref-type="bibr" rid="cit15">15</xref>]. Ограниченные сообщения о ЗТО доступны в нейроонкологической литературе и чаще всего описывается как малигнизация тритон-опухоли в виде спорадической формы на фоне нейрофиброматоза 1 типа (НФ1). Описан редкий клинический случай хирургического лечения ЗТО, спинномозгового корешка Th5 у женщины 61 года. </p></abstract><trans-abstract xml:lang="en"><p>Malignant newt tumor (MNT) is a highly aggressive malignant neoplasm classified as a variant of malignant peripheral nerve sheath tumor (MPNT) with rhabdomyoblast differentiation. MDRF with divergent (heterologous) differentiation with the presence of a rhabdoid component is extremely rare, accounting for 5 % of all MRRF, which accounts for approximately 2 % of all soft tissue sarcomas. A subgroup of tumors in which malignant Schwann cells coexist with malignant rhabdomyoblasts is called malignant newt tumor (MNT) [<xref ref-type="bibr" rid="cit10">10</xref>]. In most published clinical observations, newt tumor malignancy occurs in the head, neck, limbs, and trunk [<xref ref-type="bibr" rid="cit15">15</xref>]. Limited reports of OST are available in the neurooncological literature and are most commonly described as sporadic newt tumor malignancy in the setting of neurofibromatosis type 1 (NF1). A rare clinical case of surgical treatment of OST, Th5 spinal root in a 61-year-old woman is described. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>злокачественная опухоль периферического нерва</kwd><kwd>злокачественная тритон опухоль</kwd><kwd>хирургическое лечение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>malignant peripheral nerve tumor</kwd><kwd>malignant newt tumor</kwd><kwd>surgical treatment</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">AlAli BM, Amr SS.
