According to the literature, the follicular form of sarcoidosis is extremely rare, several isolated cases are described in foreign literature, there are no publications in the russian literature. A 30-year-old female patient came to the clinic of the Military Medical Academy with a skin rash of the upper extremities, trunk and neck that lasted for one year. Anamnesis: repeated use of topical corticosteroids for the treatment with a temporary positive effect. The skin process was represented by common follicular papules; a histological examination of one of the elements revealed granulomas of the sarcoid type, which were located perifolliculary, mainly around the infundibular sections of the hair follicles. The rash resolved after a course of external corticosteroid therapy. The clinical case described by us illustrates the need for histological examination to verify the diagnosis.</p></abstract><trans-abstract xml:lang="ru"><p>Статья посвящена редкому варианту саркоидоза кожи — так называемому фолликулярному саркоидозу. Согласно данным литературы, фолликулярная форма саркоидоза встречается крайне редко, в зарубежной литературе описано несколько единичных случаев, в отечественной литературе публикации отсутствуют. Пациентка в возрасте 30 лет обратилась в клинику Военно-медицинской академии с высыпаниями на коже верхних конечностей, туловища и шеи, существующими в течение одного года. Из анамнеза: неоднократное использование для лечения топических кортикостероидов с временным положительным эффектом. Процесс на коже был представлен распространенными фолликулярными папулами; при гистологическом исследовании одного из элементов были выявлены гранулемы саркоидного типа, которые располагались перифолликулярно, преимущественно вокруг инфундибулярных отделов волосяных фолликулов. Высыпания разрешились после проведения курса наружной кортикостероидной терапии. Описанный нами клинический случай иллюстрирует необходимость проведения гистологического исследования для верификации диагноза.</p></trans-abstract><kwd-group xml:lang="en"><kwd>sarcoidosis</kwd><kwd>follicular papules</kwd><kwd>follicular form</kwd><kwd>sarcoid granuloma</kwd><kwd>case report</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>саркоидоз</kwd><kwd>фолликулярные папулы</kwd><kwd>фолликулярная форма</kwd><kwd>саркоидная гранулема</kwd><kwd>клинический случай</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Seo KS, Yeum JS, Suh JC, Na GY.
