The fragments of palmar aponeurosis from 27 patients with Dupuytren’s contracture were examined. Paraffin sections stained with hematoxylin-eosin and Periodic Schiff-Methenamine Silver were digitized using AxioScope.A1 microscope (Carl Zeiss Micro Imaging GmbH, Germany). For examination in JSM-840 scanning electron microscope (Jeol, Japan), the samples were dehydrated after fixation, soaked in camphene, dried, and silver sprayed in the IB-6 ionizer (Eiko, Japan). <bold>Results</bold>. In paraffin sections stained with methenamine-silver, the signs of mycotic microbiota were detected only in 2 (7.4%) of 27 patients, and with the use scanning electron microscopy — in 16 patients (59%). The morphological phenotypes and ultrastructure of intercellular contacts of yeast-like fungi were similar to Candida albicans. In all cases, the budding cells were detected. The destruction of the connective tissue of the palmar aponeurosis was observed in the form of loosening, stratification, and cavities formation (the zones of lysis). <bold>Conclusion</bold>. The scanning electron microscopy allowed to evaluate the ultrastructure of fungal cells and their interaction with surrounding tissues in the surgical material from the patients with Dupuytren’s contracture. A higher percentage of detection of fungal invasion compared to the Periodic Schiff-Methenamine staining was associated with a higher resolution and the ability of a larger area of tissue samples analysis.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования</bold> — определить возможности световой и сканирующей электронной микроскопии (СЭМ) в обнаружении грибов в операционном материале от пациентов с контрактурой Дюпюитрена. <bold>Материал и методы</bold>. Исследовали фрагменты ладонного апоневроза от 27 пациентов с контрактурой Дюпюитрена. Для исследования в СЭМ JSM-840 (Jeol, Япония) образцы после фиксации обезвоживали, пропитывали в камфене, высушивали, напыляли серебром в ионном напылителе IB-6 (Eiko, Япония). Парафиновые срезы, окрашенные гематоксилином и эозином и метенамин-серебром P.A.S.M. оцифровывали с помощью микроскопа AxioScope.A1 (Carl Zeiss Micro Imaging GmbH, Германия). <bold>Результаты</bold>. При окрашивании парафиновых срезов метенамин-серебром P.A.S.M. признаки микотической микрофлоры выявлены только у двух (7,4%) из 27 пациентов, а с применением метода СЭМ — у 16 пациентов (59%). Морфологические фенотипы и ультраструктура межклеточных контактов дрожжеподобных грибов сходны с <italic>Candida albicans</italic>. Во всех случаях обнаружены почкующиеся клетки. Деструкция соединительной ткани ладонного апоневроза проявлялась в виде разрыхления, расслоения и формирования полостей — зон лизиса. <bold>Заключение</bold>. Метод СЭМ позволил оценить ультраструктуру клеток грибов и их взаимодействие с окружающими тканями в операционном материале от пациентов с контрактурой Дюпюитрена. Более высокий процент выявления грибковой инвазии по сравнению с методом P.A.S.M. связан с более высокой разрешающей способностью и возможностью анализа большей площади тканевых образцов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Dupuytren’s contracture</kwd><kwd>scanning electron microscopy</kwd><kwd>mycoses</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>контрактура Дюпюитрена</kwd><kwd>сканирующая электронная микроскопия</kwd><kwd>микозы</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ng M., Thakkar D., Southam L., Werker P., Ophoff R., Becker K., Nothnagel M. et al.
