It is most often localized in the pleura. Extrapleural lesions of the genitourinary system, including the prostate gland and especially the seminal vesicles, occur in anecdotal cases. There are no specific clinical manifestations of tumor localized in the prostate gland; it can mimic prostate adenoma with infravesical obstruction. With the localization of the tumor in the seminal vesicles, local symptoms are more common: hematuria, dysuria, and hemospermia. The basis of medical imaging is contrast-enhanced magnetic resonance imaging and combined positron emission and X-ray computed tomography with various tracers. To confirm the diagnosis, a biopsy followed by histological and immunohistochemical examination with determination of CD34 and STAT6 expression in the tumor tissue is required. The main therapy for a solitary fibrous tumor is surgical excision with a resection margin of 1–2 cm. The article presents a unique clinical case of a primary multiple synchronous solitary fibrous tumor of the prostate and seminal vesicle combined with prostate cancer. This is the first such case described in the available Russian and international literature. Timely diagnosis of these neoplasms enables a rational approach to personalized treatment.</p></abstract><trans-abstract xml:lang="ru"><p>Солитарная фиброзная опухоль – крайне редкое фибропластическое новообразование мезенхимальной природы, которое имеет неопределенный злокачественный потенциал с промежуточным биологическим поведением. Чаще всего локализуется в плевре. Экстраплевральные поражения мочеполовой системы, включая предстательную железу (ПЖ) и особенно семенные пузырьки, встречаются в единичных случаях. Специфические клинические проявления при локализации в ПЖ отсутствуют, может имитировать аденому ПЖ с явлениями инфравезикальной обструкции. При локализации опухоли в семенных пузырьках чаще наблюдались локальные симптомы: гематурия, дизурия, гемоспермия. Основа медицинской визуализации – магнитно-резонансная томография с контрастированием и комбинированная позитронно-эмиссионная и рентгеновская компьютерная томография с различными трейсерами. Для подтверждения диагноза необходима биопсия с последующим гистологическим и иммуногистохимическим исследованием с определением экспрессии в опухолевой ткани CD34 и STAT6. Основной метод лечения солитарной фиброзной опухоли – хирургический, в объеме иссечения с отступом края 1–2 см. В статье представлен уникальный клинический случай первичной множественности синхронных солитарных фиброзных опухолей ПЖ и семенного пузырька в сочетании с раком ПЖ. Такой случай в доступной отечественной и зарубежной литературе описан впервые. Своевременная диагностика этих новообразований позволяет выбрать рациональную тактику персонализированного лечения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>solitary fibrous tumor</kwd><kwd>prostate gland</kwd><kwd>seminal vesicle</kwd><kwd>prostate cancer</kwd><kwd>magnetic resonance imaging</kwd><kwd>immunohistochemistry</kwd><kwd>treatment</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>солитарная фиброзная опухоль</kwd><kwd>предстательная железа</kwd><kwd>семенной пузырек</kwd><kwd>рак предстательной железы</kwd><kwd>магнитно-резонансная томография</kwd><kwd>иммуногистохимия</kwd><kwd>лечение</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Klemperer P, Coleman B.R.
