Его причиной могут быть автономные нарушения и другие патологические состояния. В большей части случаев это идиопатическое расстройство с доброкачественным течением. Тем не менее СА может быть проявлением серьезных заболеваний, а также осложнением хирургических вмешательств на шейном и верхнегрудном уровнях позвоночника. Представлены описание случая идиопатического СА и краткий обзор литературы.</p></abstract><trans-abstract xml:lang="en"><p>Harlequin syndrome (HA) is a rare pathology. It is manifested by isolated unilateral facial flushing (less often the face and limb), sometimes with concomitant hyperhidrosis and Horner’s syndrome. In most cases, this is an idiopathic condition with a benign course. However, HA can be a manifestation of serious diseases, as well as a complication of surgical interventions at the cervical and upper thoracic levels. We present clinical case of a female patient with Harlequin syndrome as well as a short review of scientific literature.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>синдром Арлекина</kwd><kwd>автономная нервная система</kwd><kwd>симпатическая система</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Harlequin syndrome</kwd><kwd>autonomic nervous system</kwd><kwd>sympathetic system</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">Белопасов В.В., Губанова М.В., Белопасова А.В.
