A special form of BC is the hidden or occult form. Taking into account the analysis of methods for the diagnosis and treatment of occult BC, it is important that this form of the disease is detected at a later stage. It includes axillary lymphadenopathy and histologically appears to be a metastatic lesion of the lymph nodes from undetectable invasive BC.</p><p><bold>Materials and methods.</bold> We conducted a thorough analysis of domestic and foreign literature and described two clinical examples with authentic documentation of the results of the examination and treatment. The article describes in detail the schemes of drug treatment and descriptions of the results of morphological examination of the surgical material.</p><p><bold>Results.</bold> Given the complexity of the diagnostic stage, the clinical form of the course of diseases, the described clinical examples can be attributed specifically to the occult form of BC. An important and determining factor in treatment is the diagnostic stage using all possible methods, including positron emission tomography–computed tomography, breast magnetic resonance imaging and trepan-biopsy of regional lymph nodes, followed by the determination of the molecular biological subtype of the tumor.</p><p><bold>Conclusions.</bold> In this article, the presented data confirm the general statement about the uniqueness of this disease, which requires a more detailed and multidisciplinary approach at the stage of diagnosis and determination of treatment tactics.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> В настоящее время существует несколько форм рака молочной железы (РМЖ): узловая, диффузная, представленная отечно-инфильтративной, маститоподобной формой, а также рак Педжета. Особой же формой РМЖ является скрытая, или оккультная форма. С учетом проведенного анализа методов диагностики и лечения оккультного РМЖ важным является то, что данная форма заболевания выявляется уже на поздних стадиях. Она включает в себя подмышечную лимфаденопатию и гистологически представляется метастатическим поражением лимфатических узлов от неопределяемого инвазивного РМЖ.</p><p><bold>Материалы и методы.</bold> Нами был проведен тщательный анализ отечественной и зарубежной литературы и описаны 2 клинических примера с подлинной документацией по результатам проведенного обследования и лечения. В статье подробно описаны схемы проведенного лекарственного лечения и результаты морфологического исследования операционного материала.</p><p><bold>Результаты.</bold> Учитывая сложность диагностического этапа, клиническую форму течения заболеваний, описанные клинические примеры можно отнести именно к оккультной форме РМЖ. Важным и определяющим фактором в лечении является диагностический этап с применением всех возможных методов, включая позитронно-эмиссионную томографию, совмещенную с компьютерной томографией, магнитно-резонансную томографию молочных желез и трепанобиопсию регионарных лимфатических узлов с последующим определением молекулярно-биологического подтипа опухоли.</p><p><bold>Выводы.</bold> Представленные данные подтверждают всеобщее утверждение об уникальности данного заболевания, которое требует более детального и мультидисциплинарного подхода на этапе диагностики и определения тактики лечения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>occult breast cancer</kwd><kwd>immunohistochemical analysis</kwd><kwd>breast magnetic resonance imaging</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>оккультный рак молочной железы</kwd><kwd>иммуногистохимическое исследование</kwd><kwd>магнитнорезонансная томография молочных желез</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Terada M., Aachi Y., Sawaki M. et al.
