PCNSL is a rare extranodal form of NHL that occurs only in the CNS – in the brain, spinal cord, meninges, in the eyes, and not extending beyond CNS. Its frequency in adults is 1–2 % of lymphomas and 5 % of all CNS tumors. Data on prevalence in childhood are not available, limited to some case reports. This article presents a literature review about PCNSL diagnosis and treatment and case report of such lymphoma with intraspinal lesion in 11 years old child.</p></abstract><trans-abstract xml:lang="ru"><p>Поражение центральной нервной системы (ЦНС) при распространенных неходжкинских лимфомах (особенно в случаях опухолей из зрелых В-клеток у детей) встречается нередко в отличие от первичной лимфомы ЦНС (ПЛЦНС), которая является редкой экстранодальной формой неходжкинских лимфом, возникающей только в пределах ЦНС (в головном, спинном мозге, в оболочках мозга, в глазах). Частота ее встречаемости составляет у взрослых 1–2 % от числа лимфом и 5 % от всех опухолевых поражений ЦНС. Данные о распространенности в детском возрасте отсутствуют и ограничены описанием отдельных случаев. В данной статье представлен обзор литературы, посвященный диагностике и терапии ПЛЦНС, и продемонстрирован клинический случай такой лимфомы с интраспинальным поражением у ребенка 11 лет.</p></trans-abstract><kwd-group xml:lang="en"><kwd>primary central nervous system large B-cell lymphoma</kwd><kwd>non-Hodgkin's lymphoma</kwd><kwd>rituximab</kwd><kwd>children</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>первичная лимфома центральной нервной системы</kwd><kwd>неходжкинские лимфомы</kwd><kwd>ритуксимаб</kwd><kwd>дети</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Batchelor T., Loeffler J.S.
