This review highlights the advantages and limitations of diagnostic methods used to verify autoimmune bullous dermatoses and presents the sensitivity and specificity data for an immunohistochemical assay and its potential use as an alternative diagnostic method to verify a suspected pemphigus vulgaris.</p></abstract><trans-abstract xml:lang="ru"><p>Применяемые в настоящее время методы диагностики вульгарной пузырчатки основываются на понимании иммунологических механизмов, опосредующих развитие заболевания, где ведущая роль отводится продукции аутоантител, нацеленных на структурные белки эпителиальной ткани и подлежащей базальной мембраны. В обзоре освещены преимущества и недостатки методов диагностики, используемых для верификации аутоиммунных буллезных дерматозов, приведены данные о чувствительности и специфичности иммуногистохимического метода исследования и перспективы применения в качестве альтернативного метода диагностики при подозрении на вульгарную пузырчатку.</p></trans-abstract><kwd-group xml:lang="en"><kwd>pemphigus</kwd><kwd>immunohistochemical assay</kwd><kwd>direct immunofluorescence reaction</kwd><kwd>enzyme-linked immunosorbent assay</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>пузырчатка</kwd><kwd>иммуногистохимическое исследование</kwd><kwd>реакция прямой иммунофлюоресценции</kwd><kwd>иммуноферментный анализ</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The manuscript was prepared and published as part of the fulfillment of the state task of the State Research Center of Dermatovenereology and Cosmetology of the Ministry of Health of the Russian Federation No. 056-00013-26-00.</funding-statement><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания ФГБУ «ГНЦДК» Минздрава России № 056-00013-26-00.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Egami S, Yamagami J, Amagai M.
