As a child, she was diagnosed with herpetiform dermatitis on the base of a clinical picture and histological data. After the period of puberty, when in addition to skin blistering a lesion of the oral mucosa, dystrophy and absence of nail plates, contracture of the 2 fingers of the hands arose, the diagnosis was changed to dystrophic congenital bullous epidermolysis, which did not contradict with re-histological examination of the skin. In order to clarify the diagnosis, another biopsy of the leg skin was performed in 2016. The light microscopy data corresponded to the herpetiform dermatitis or vesicular form of the bullous pemphigoid, the acquired bullous epidermolysis was not also excluded. Indirect RIF allowed to reject the diagnosis of herpetiform dermatitis. The possibility of bullous pemphigoid developing on the background of preexisting congenital bullous epidermolysis was investigated by immunofluorescence mapping with antibodies to 13 structural proteins of the dermo-epidermal junction. Expression of all the studied proteins corresponded to that of healthy individuals, which conflicted with the diagnosis of congenital bullous epidermolysis. Additional immunofluorescence study of the sites of spontaneous cleavage of the biopsy specimen, as well as of n- and u-patterns in the structure of the luminescence line, made possible to exclude the bullous pemphigoid. So, the use of a complex of immunomorphological methods helped to establish the correct diagnosis.</p></abstract><trans-abstract xml:lang="ru"><p>В детстве на основании клинической картины и данных гистологического исследования ей был поставлен диагноз герпетиформного дерматита. После периода полового созревания, когда помимо кожных пузырных высыпаний возникли поражение слизистой оболочки полости рта, дистрофия и отсутствие ногтевых пластин, контрактура II пальцев кистей, диагноз был изменен в пользу дистрофического врожденного буллезного эпидермолиза, чему не противоречили данные повторного гистологического исследования кожи. С целью уточнения диагноза в 2016 г. была проведена еще одна биопсия кожи голени. Данные световой микроскопии соответствовали герпетиформному дерматиту или везикулезной форме буллезного пемфигоида, не исключался также приобретенный буллезный эпидермолиз. Непрямая реакция иммунофлюоресценции позволила отвергнуть диагноз герпетиформного дерматита. Возможность развития буллезного пемфигоида на фоне предсуществующего врожденного буллезного эпидермолиза была исследована методом иммунофлюоресцентного картирования с антителами к 13 структурным белкам дермоэпидермального соединения. Экспрессия всех исследованных белков соответствовала таковой у здоровых лиц, что противоречило диагнозу врожденного буллезного эпидермолиза. Дополнительное иммунофлюоресцентное изучение участков спонтанного расщепления биоптата, а также n- и u-паттернов в структуре линии свечения позволило исключить буллезный пемфигоид. Таким образом, использование комплекса иммуноморфологических методик помогло установить правильный диагноз.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>приобретенный буллезный эпидермолиз</kwd><kwd>непрямая реакция иммунофлюоресценции</kwd><kwd>иммунофлюоресцентное картирование</kwd><kwd>acquired bullous epidermolysis</kwd><kwd>indirect reaction of immune fluorescence</kwd><kwd>immune fluorescence mapping</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Baum S., Sakka N., Artsi O. et al.
