A comprehensive examination involving a neurologist, dermatologist, and rheumatologist was conducted to establish the diagnosis and select the optimal therapy. Significant clinical improvement in the patient's condition is demonstrated against the background of pregabalin therapy. The importance of a multidisciplinary approach and the difficulty of diagnosis due to the lack of specific examination methods and insufficient awareness of doctors about this disease are emphasized. The described case demonstrates the need for a personalized approach to managing patients with erythromelalgia to improve their quality of life.</p></abstract><trans-abstract xml:lang="ru"><p>В статье представлен клинический случай вторичной эритромелалгии у коморбидной пациентки с антифосфолипидным синдромом, сопровождающейся жгучей болью, гиперемией и отеком нижних конечностей. Представлено комплексное обследование пациентки с привлечением невролога, дерматолога и ревматолога для установки диагноза и подбора оптимальной терапии. Продемонстрировано значимое клиническое улучшение состояния пациентки на фоне терапии прегабалином. Подчеркивается важность мультидисциплинарного подхода и трудность диагностики, обусловленные отсутствием специфических методов обследования и недостаточной осведомленностью врачей о таком заболевании. Описанный случай демонстрирует необходимость персонализированного подхода к ведению пациентов с эритромелалгией для улучшения качества их жизни.</p></trans-abstract><kwd-group xml:lang="en"><kwd>erythromelalgia</kwd><kwd>antiphospholipid syndrome</kwd><kwd>Mitchell syndrome</kwd><kwd>acrocyanosis</kwd><kwd>burning pain</kwd><kwd>SCN9A gene mutations</kwd><kwd>Nav1.7 sodium channels</kwd><kwd>comorbid patient</kwd><kwd>clinical case</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эритромелалгия</kwd><kwd>антифосфолипидный синдром</kwd><kwd>синдром Митчелла</kwd><kwd>акроцианоз</kwd><kwd>жгучая боль</kwd><kwd>мутации в гене SCN9A</kwd><kwd>натриевые каналы Nav1.7</kwd><kwd>коморбидный пациент</kwd><kwd>клинический случай</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Tang Z, Chen Z, Tang B, Jiang H.
