The classical triad includes cutaneous fibrofolliculomas, spontaneous pneumothorax, and multiple renal tumors. However, the disease exhibits variable expressivity; renal manifestations may be the first and only symptom in young patients, leading to diagnostic difficulties and risk of suboptimal treatment. In cases of isolated renal involvement, BHDS diagnosis is often delayed. Reports in the Russian literature remain scarce.</p> <p>Aim. To present a clinical case of BHDS in a 35-year-old female patient presenting with bilateral multifocal renal tumors (oncocytoma and chromophobe renal cell carcinoma) and multiple pulmonary cysts, successfully managed with staged bilateral laparoscopic partial nephrectomy. This case illustrates a modern diagnostic algorithm, underlines the importance of multidisciplinary approach (radiology, morphology, genetics) and justifies the necessity of including BHDS in differential diagnosis of renal neoplasms in young patients.</p></abstract><trans-abstract xml:lang="ru"><p>Синдром Бирта–Хогга–Дюбе (Birt–Hogg–Dubé syndrome, BHDS) – редкое аутосомно-доминантное заболевание, обусловленное патогенными мутациями в гене-супрессоре опухолей <italic>FLCN</italic>. Классическая триада включает фиброфолликуломы кожи, спонтанный пневмоторакс и множественные опухоли почек. Заболевание отличается вариабельной экспрессивностью: почечные проявления могут быть первым и единственным симптомом у молодых пациентов, что приводит к диагностическим трудностям и риску неоптимального лечения. Диагностика BHDS при изолированном почечном поражении часто запаздывает. В отечественной литературе описания подобных случаев единичны.</p> <p>Целью публикации является представление клинического случая BHDS у 35-летней пациентки, манифестировавшего двусторонними мультифокальными опухолями почек (сочетание онкоцитомы и хромофобного почечно-клеточного рака) и множественными легочными кистами, потребовавшего двусторонней лапароскопической парциальной нефрэктомии. На примере данного наблюдения иллюстрируется современный диагностический алгоритм, подчеркивается важность междисциплинарного подхода (лучевая диагностика, патоморфология, генетика) и обосновывается необходимость включения BHDS в дифференциальный диагноз при выявлении почечных новообразований у молодых пациентов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Birt–Hogg–Dubé syndrome</kwd><kwd>FLCN</kwd><kwd>mutation</kwd><kwd>oncocytoma</kwd><kwd>chromophobe renal cell carcinoma</kwd><kwd>hereditary cancer syndromes</kwd><kwd>laparoscopic partial nephrectomy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>синдром Бирта–Хогга–Дюбе</kwd><kwd>FLCN</kwd><kwd>мутация</kwd><kwd>онкоцитома</kwd><kwd>хромофобный почечно-клеточный рак</kwd><kwd>наследственные опухолевые синдромы</kwd><kwd>лапароскопическая парциальная нефрэктомия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Nickerson M.L., Warren M.B., Toro J.R. et al.
