One of the rather rare variants of follicular lymphoma is pediatric follicular lymphoma. This variant, despite the name, is diagnosed not only in children, but also among young adults. Pediatric follicular lymphoma is characterized by early (I, II) stages, the absence or weak BCL2 expression, and the predominant absence of t(14;18)(q32;q21) translocation. Treatment tactics vary widely from radical surgical tumor resection with subsequent follow-up to chemoimmunotherapy with rituximab.</p><p>This article presents a clinical case of advanced pediatric follicular lymphoma (stage III) in a 5-year-old patient. Using a combined treatment approach (surgery followed by immunochemotherapy) allowed to achieve a complete metabolic response which lasts more than a year.</p></abstract><trans-abstract xml:lang="ru"><p>Фолликулярная лимфома является одной из наиболее часто встречающихся неходжкинских лимфом у взрослых. Одним из достаточно редких вариантов фолликулярной лимфомы является фолликулярная лимфома педиатрического типа. Данный вариант, несмотря на название, диагностируется не только у детей, но и среди молодых взрослых. Для фолликулярной лимфомы педиатрического типа свойственны ранние (I, II) стадии, отсутствие или слабая экспрессия BCL2, преимущественное отсутствие транслокации t(14;18)(q32;q21). Тактика лечения широко варьирует от радикального хирургического удаления опухоли с последующим наблюдением до химиоиммунотерапии с ритуксимабом.</p><p>В настоящей статье приводится клиническое наблюдение распространенной фолликулярной лимфомы педиатрического типа (III стадия) у больного 5 лет. С использованием комбинированного подхода к лечению (проведение операции с последующей иммунохимиотерапией) удалось достичь полного метаболического ответа, который сохраняется больше года.</p></trans-abstract><kwd-group xml:lang="en"><kwd>follicular lymphoma</kwd><kwd>pediatric type follicular lymphoma</kwd><kwd>oncology</kwd><kwd>hematology</kwd><kwd>diagnosis</kwd><kwd>treatment</kwd><kwd>immunochemotherapy</kwd><kwd>surgery</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>фолликулярная лимфома</kwd><kwd>фолликулярная лимфома педиатрического типа</kwd><kwd>онкология</kwd><kwd>гематология</kwd><kwd>диагностика</kwd><kwd>лечение</kwd><kwd>иммунохимиотерапия</kwd><kwd>хирургия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Rudreshaa A.H., Goyal S., Lokanatha D. et al.
