In this connection, the “postulate” in the diagnosis and treatment of ACC should be a multidisciplinary approach in centers with experience in adrenal surgery and pathomorphology. The presented own clinical observations of patients with ACC diagnosed during a multiple revision of histological slides and repeated immunohistochemistry including recurrent tumor, illustrates the complexity of differential diagnosis and shows the need for further study of the subcellular mechanisms of adrenocortical oncogenesis underlying its clinical picture, morphology, and expression of valuable specific markers.</p></abstract><trans-abstract xml:lang="ru"><p>Трудности дифференциальной диагностики адренокортикального рака обусловлены его гетерогенным клинико-биологическим поведением, в основе которого лежит сложный гистогенез и молекулярно-генетический ландшафт адренокортикальных клеток. В связи с чем в диагностике и лечении адренокортикального рака важен мультидисциплинарный подход в центрах с опытом хирургии надпочечников и патоморфологических исследований. Приведенные собственные клинические наблюдения пациентов с диагнозом адренокортикального рака, диагностированным при многократном пересмотре гистологических препаратов и повторной иммуногистохимии, в том числе рецидивной опухоли, иллюстрируют сложности дифференциальной диагностики и показывают необходимость дальнейшего изучения субклеточных механизмов адренокортикального онкогенеза, лежащих в основе его клиники, морфологии и экспрессии ценных специфических маркеров.</p></trans-abstract><kwd-group xml:lang="en"><kwd>adrenocortical cancer</kwd><kwd>differential diagnosis</kwd><kwd>pathomorphology</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>адренокортикальный рак</kwd><kwd>дифференциальная диагностика</kwd><kwd>патоморфология</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Chandrasekar T., Goldberg H., Klaassen Z. et al.
