However, the diagnosis and treatment of this kind of progression are still difficult for pediatricians and pediatric oncologists due to the small absolute number of PM RMS patients, which makes it impossible to accumulate sufficient clinical experience, as well as due to the absence of a pathognomonic clinical picture and a standardized specific therapy. The article describes 3 clinical cases of LC during PM RMS and provides an overview of existing literature focusing on this problem. Parents patients agreed to use personal data in research and publications.</p></abstract><trans-abstract xml:lang="ru"><p>Развитие лептоменингеального канцероматоза (ЛМК) – достаточно частое событие при рабдомиосаркоме параменингеальной локализации (РМС ПМ). Однако диагностика и лечение данного вида прогрессирования до сих пор представляют трудности для педиатров и детских онкологов, что связано с малым абсолютным числом больных с РМС ПМ, не позволяющим накопить достаточный клинический опыт, отсутствием патогномоничной клинической картины и стандартизованной специфической терапии. В статье представлены описания трех клинических случаев развития ЛМК при РМС ПМ и обзор литературы, посвященный этой проблеме. Родители пациентов дали согласие на использование информации в научных исследованиях и публикациях.</p></trans-abstract><kwd-group xml:lang="en"><kwd>leptomeningeal carcinomatosis</kwd><kwd>a disseminated lesion of the meninges</kwd><kwd>parameningeal rhabdomyosarcoma</kwd><kwd>head and neck tumors</kwd><kwd>children</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>лептоменингеальный канцероматоз</kwd><kwd>диссеминированное поражение мозговых оболочек</kwd><kwd>рабдомиосаркома параменингеальной локализации</kwd><kwd>опухоли головы и шеи</kwd><kwd>дети</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">1.
