Чаще всего в клинической практике встречаются классические варианты заболевания, не вызывающие трудностей в их верификации. Но у части пациентов присутствуют признаки, характерные для разных заболеваний соединительной ткани. Такое сочетание признаков получило название смешанного заболевания соединительной ткани, или «перекрестного синдрома» (Overlap-синдром). Полиорганный характер клинической картины заболевания представляет диагностическую трудность для клинициста и приводит к поздней постановке диагноза, малоэффективной терапии, инвалидизации пациента. В статье представлен клинический случай смешанного заболевания соединительной ткани у пациента среднего возраста. Проведен анализ литературных источников, клинических данных, результатов лабораторных исследований.</p></abstract><trans-abstract xml:lang="en"><p>   Systemic connective tissue diseases are a heterogeneous group of diseases with unclear etiology, the pathogenesis of which is represented by an autoimmune process, a heterogeneous clinical picture and a variable course. Classical variants of the disease that do not cause difficulties in their verification are most common in clinical practice. But some patients have signs characteristic of various connective tissue diseases. This combination of symptoms is called mixed connective tissue disease or “cross syndrome” (Overlap-syndrome). The multi-organ nature of the clinical picture of the disease presents a diagnostic difficulty for the clinician and leads to late diagnosis, ineffective therapy, and disability of the patient. The article presents a clinical case of mixed connective tissue disease in a middle-aged patient. An analysis of literary sources, clinical data, and laboratory results was carried out.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>смешанное заболевание соединительной ткани</kwd><kwd>клинический случай</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mixed connective tissue disease</kwd><kwd>clinical case</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено без спонсорской поддержки</funding-statement><funding-statement xml:lang="en">The study was conducted without sponsorship</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Бубневич Т.Е., Зарянкина А.И., Ивкин С.С.
