Развитие внесуставных (системных) проявлений РА ассоциируется с присутствием высоких концентраций ревматоидного фактора и антител к циклическому цитруллинированному пептиду. Особенностью течения РУ в легочной ткани является нередкое их возникновение при минимально выраженных воспалительных изменениях в суставах или ремиссии. В редких случаях РУ подвергаются распаду и нагноению, которые могут осложниться образованием небольших каверн, кровохарканьем, а при субплевральной локализации – пневмотораксом. Кроме того, имеются публикации о возможной связи образования и ускорения развития РУ с приемом иммуносупрессивных препаратов (метотрексата, тоцилизумаба, D-пеницилламина, солей золота, лефлуномида, инфликсимаба и других ингибиторов фактора некроза опухоли α) и о связи РУ легочной локализации с лечением метотрексатом. Представлено клиническое наблюдение больной с overlap-синдромом – сочетанием РА и системной склеродермии, с развитием РУ в легочной ткани в ранние сроки от начала заболевания, когда уже был достигнут целевой уровень активности РА (по DAS28). Атипичная конфигурация узла в легком потребовала дифференциально-диагностического поиска. Демонстрируются результаты визуализации РУ в легких и их динамика. Обсуждаются представленные данные.</p></abstract><trans-abstract xml:lang="en"><p>Rheumatoid nodules (RNs) are one of the most common extra-articular manifestations of rheumatoid arthritis (RA), but are rarely located in lung tissue. The development of extra-articular (systemic) manifestations of RA is associated with the high levels of rheumatoid factor and anticyclic citrullinated peptide antibodies. The specific features of the course of RNs in lung tissue are their frequent occurrence with minimally pronounced joint inflammatory changes or remission. In rare cases, RNs are prone to disintegration and suppuration, which may be complicated by the formation of small caverns, hemoptysis, and, if located subpleurally, pneumothorax. In addition, there are publications on the possible relationship of the formation of RNs and their accelerated development to the administration of immunosuppressive drugs (methotrexate, tocilizumab, D-penicillamine, gold salts, leflunomide, infliximab, and other TNF-α inhibitors) and on the association of pulmonary RNs with methotrexate treatment. The paper describes a clinical case of a female patient with RA-systemic sclerosis overlap syndrome and RN formation in lung tissue early at disease onset when the DAS28 target level for RA has been achieved. The atypical outline of a pulmonary nodule has required a differential diagnostic search. The results of imaging RNs in the lung and their dynamics are shown. The given data are discussed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ревматоидный артрит</kwd><kwd>overlap-синдром</kwd><kwd>системная склеродермия</kwd><kwd>внесуставные проявления</kwd><kwd>ревматоидные узелки</kwd><kwd>метотрексат</kwd><kwd>лефлуномид</kwd><kwd>сульфасалазин</kwd><kwd>узлы в легких</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rheumatoid arthritis</kwd><kwd>overlap syndrome</kwd><kwd>systemic sclerosis</kwd><kwd>extra-articular manifestations</kwd><kwd>rheumatoid nodules</kwd><kwd>methotrexate</kwd><kwd>leflunomide</kwd><kwd>sulfasalazine</kwd><kwd>pulmonary nodules</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">Turesson C, O'Fallon WM, Crowson CS, et al.
