        <p>Введение. Первичное кожное CD4+ лимфопролиферативное заболевание из мелких и средних клеток (ПК CD4+ Т-ЛПЗ из мелких/средних клеток) – новая нозологическая единица, выделенная в классификации ВОЗ 2017 года. Цель исследования – охарактеризовать морфологические и иммуногистохимические признаки ПК CD4+ Т-ЛПЗ из мелких/средних клеток. Материалы и методы. В исследовании изучено 28 биоптатов кожи пациентов с ПК CD4+ Т-ЛПЗ из мелких и средних клеток (13 мужчин и 15 женщин). На срезах с парафиновых блоков были проведены гистологические и иммуногистохимические исследования. Результаты. При проведении гистологического исследования характер роста инфильтрата кожи был представлен нодулярным, очагово-диффузным, диффузным типом. В каждом случае определялась выраженная лимфоидная инфильтрация Т-клетками с иммунофенотипом фолликулярных Т-хелперов (Tfh-иммунофенотип), количество В-клеток варьировало. Заключение. ПК CD4+ Т-ЛПЗ из мелких и средних клеток – редкое заболевание, которое требует дальнейшего изучения для определения критериев диагностики и лечения.</p>

        <p>Introduction. Primary cutaneous CD4+ lymphoproliferative disorder of small and medium cells (PC CD4+ T-LPD small/medium cell) is a new entity identified in the WHO classification published in 2017. The aim of the research was to characterize morphological and immunohistochemical features of PC CD4+ T-LPD small/medium cell. Materials and methods. The study examined 28 skin biopsies from 13 males and 15 females with PC CD4+ T-LPD small/medium cell using histological and immunohistochemical methods.  Results. We detected growth pattern to be of nodular, focal–diffuse, and diffuse types. Each case was characterized by significant T-cell lymphoid infiltration with an immunophenotype of follicular T-helper cells (Tfh-immunophenotype), the number of B-cells varying. Conclusion. PC CD4+ T-LPD from small and medium cells is a rare disease that requires further study to determine the criteria for diagnosis and treatment. Keywords: primary cutaneous CD4+ small/medium T-cell lymphoproliferative disorder, T follicular helper cells, immunophenotype</p>
