To date, about 40 cases of this pathology have been described in international literature. Solitary fibrous tumors are asymptomatic for a long time and are usually an incidental radiological examination. To differentiate a solitary fibrous tumor from other mesenchymal neoplasms, it is necessary to conduct an immunohistochemical study to determine STAT6 expression. The main and most effective method of treatment is surgery. In this article we present a unique clinical case of a patient with synchronous tumors: malignant solitary fibrous tumor of the prostate (risk of metastasis (WHO 2020) intermediate); prostate cancer stage II (pT2N0M0R0, Gleason 6 (3 + 3)).</p></abstract><trans-abstract xml:lang="ru"><p>Солитарная фиброзная опухоль предстательной железы является крайне редким новообразованием мезенхимальной природы. На сегодняшний день в мировой литературе описано около 40 случаев данной патологии. Солитарная фиброзная опухоль длительное время протекает бессимптомно и зачастую является случайной находкой при проведении рентгенологического обследования. Для дифференциальной диагностики солитарной фиброзной опухоли с другими мезенхимальными новообразованиями обязательно проведение иммуногистохимического исследования с определением экспрессии STAT6. Основным и наиболее эффективным методом лечения является хирургический. В статье представлен уникальный клинический случай первично-множественных синхронных злокачественных опухолей: солитарной фиброзной опухоли предстательной железы (риск метастазирования по классификации Всемирной организации здравоохранения (2020) промежуточный) и рака предстательной железы II стадии (pT2N0M0R0, сумма баллов по шкале Глисона 6 (3 + 3)).</p></trans-abstract><kwd-group xml:lang="en"><kwd>solitary fibrous tumor</kwd><kwd>prostate cancer</kwd><kwd>STAT6</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>солитарная фиброзная опухоль</kwd><kwd>рак предстательной железы</kwd><kwd>STAT6</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Marcal L.P., Surabhi V.R., Ramani N.S. et al.
