Изолированное вовлечение легких наблюдается редко, при визуализации оно может имитировать злокачественное новообразование и представляет немалые трудности при диагностике. В приведенном клиническом наблюдении продемонстрирован случай изолированного IgG4-АЗ легких у 16-летнего подростка со случайно обнаруженными двусторонними узловыми изменениями на рентгенограмме органов грудной клетки при отсутствии симптомов. В связи с подозрением на злокачественную природу выявленных изменений у пациента выполнены хирургические вмешательства, при этом уровень IgG4 в сыворотке крови был в пределах нормы. Гистологически выявлена значительная лимфоплазмоцитарная инфильтрация с образованием лимфоидных фолликулов, перибронхиальный фиброз, облитерация сосудов. По результатам иммуногистохимического исследования показана инфильтрация интерстиция IgG4-позитивными плазматическими клетками. На основании приведенного клинического наблюдения сделан вывод, что при дифференциальной диагностике и обнаружении нодулярных образований на момент постановки диагноза изолированное IgG4-АЗ легких необходимо рассматривать даже при отсутствии клинических симптомов со стороны других органов.</p></abstract><trans-abstract xml:lang="en"><p>Immunoglobulin G4-related disease is a recently recognized systemic immune-mediated condition characterized by lymphoplasmacytic infiltrate in various organs with IgG4 positive plasma cells. Isolated lung involvement is rare, difficult to diagnose and can mimic primary lung malignancy on imaging. We report the case of an isolated IgG4-related interstitial lung disease in a 16-year-old asymptomatic male adolescent with incidentally found bilateral nodular lesions by chest radiograph. The patient underwent surgical interventions for assumption of malignancy. Serum IgG4 levels was normal. Нistological examination revealed significant lymphoplasmacytic infiltrate with lymphoid follicle formation, peribronchial fibrosis, vascular obliteration. Prominent interstitial IgG4 positive plasma cell infiltrate was identified by immunohistochemistry. Isolated IgG4-related lung disease should be taken into account as a possible differential diagnosis of mass-forming lesions, even when no other organ manifestation is clinically apparent at the time of diagnosis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>иммуноглобулин G4-ассоциированное заболевание легких</kwd><kwd>иммуноглобулин-G4-позитивные плазмоклеточные инфильтраты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>IgG4-related lung disease</kwd><kwd>IgG4 positive plasma cell infiltrates</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">Sedhom R., Sedhom D., Strair R.
