Гистиоцитоз из клеток Лангерганса (ГКЛ) — редкое клональное заболевание, характеризующееся инфильтрацией органов клетками CD1a+/CD207+. Лёгочный вариант встречается преимущественно у взрослых курильщиков и часто маскируется под ХОБЛ или интерстициальные заболевания легких.Цель. Продемонстрировать клинический случай ГКЛ с мультисистемным поражением (легкие, кости черепа, гипофиз), дебютировавшим респираторными симптомами, и показать сложности его дифференциальной диагностики в амбулаторной практике.Материалы и методы. Проведен ретроспективный анализ клинико-лабораторных данных пациентки 48 лет, включая результаты спирометрии, КТ ОГК, МРТ головного мозга и видеоторакоскопической биопсии легкого.Результаты. У пациентки с длительным стажем курения диагностирована ХОБЛ без эффекта от базисной терапии. При углубленном обследовании выявлены кистозная перестройка легочной ткани, несахарный диабет и выпадение зубов. Диагноз верифицирован морфологически при ВАТС-биопсии. На фоне иммуносупрессивной терапии отмечена стабилизация процесса.Заключение. Латентное течение и отсутствие патогномоничных признаков ГКЛ требуют высокой онкологической настороженности. «Золотым стандартом» диагностики остается хирургическая биопсия легкого. Своевременное начало патогенетической терапии обеспечивает благоприятный прогноз.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Langerhans Cell Histiocytosis (LCH) is a rare clonal disorder characterized by the infiltration of organs with CD1a+/CD207+ cells. The pulmonary variant predominantly affects adult smokers and often mimics COPD or interstitial lung diseases.Aim. To demonstrate a clinical case of multisystem LCH (lungs, skull bones, pituitary gland) presenting with respiratory symptoms and to highlight the difficulties of its differential diagnosis in outpatient practice.Materials and Methods. A retrospective analysis of clinical and laboratory data from a 48-year-old female patient was performed, including spirometry, chest CT, brain MRI, and video-assisted thoracoscopic lung biopsy results.Results. In a patient with a long history of smoking, COPD was diagnosed without effect from basic therapy. Further examination revealed cystic restructuring of lung tissue, diabetes insipidus, and tooth loss. The diagnosis was morphologically verified via VATS biopsy. Stabilization of the process was achieved under immunosuppressive therapy.Conclusion. The latent course and lack of pathognomonic signs of LCH require high oncological vigilance. Surgical lung biopsy remains the "gold standard" for diagnosis. Timely initiation of pathogenetic therapy ensures a favorable prognosis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гистиоцитоз из клеток Лангерганса</kwd><kwd>лёгочный гистиоцитоз</kwd><kwd>несахарный диабет</kwd><kwd>биопсия лёгкого</kwd><kwd>дифференциальная диагностика</kwd><kwd>взрослые</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Langerhans Cell Histiocytosis</kwd><kwd>Pulmonary histiocytosis</kwd><kwd>Diabetes insipidus</kwd><kwd>Lung</kwd><kwd>Differential diagnosis</kwd><kwd>Adult</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Cormac McCarthy, Beatriz Lara Gallego, Bruce C Trapnell, et al.
