To investigate the signs of neoplastic transformation of the epithelium in the foci of ovarian endometriosis (OE). Material and methods. Histological and immunohistochemical examinations were used to study 78 and 35 OE cases, respectively, and 8 adenocarcinomas. Anti-Ki-67, anti-Bcl-2, anti-p53, and anti-hepatocyte nuclear factor-1ß (HNF-1ß) antibodies were employed. Results. The epithelium of endometrioid cyst walls showed papillary syncytial changes (39.7%), metaplasia with clear cytoplasm cells (15.4%), and epithelial atypia with a low-to-relatively low Ki-67 and Bcl-2 expression and with a low p53 expression (41.0%). The expression of HNF-1ß in the foci with and without atypia was revealed in 94.7 and 56.3% of cases, respectively; it was detected only in clear cell adenocarcinomas. Conclusion. HNF-1ß hyperexpression suggests the adaptive nature and histogenetic relationship of OE to clear cell tumors of the ovary.</p></abstract><trans-abstract xml:lang="ru"><p>Цель исследования. Изучить признаки неопластической трансформации эпителия очагов эндометриоза яичников (ЭЯ). Материал и методы. Гистологическим и иммуногистохимическим методами изучено 78 и 35 наблюдений ЭЯ, соответственно, и 8 аденокарцином. Использовали антитела к белку Ki-67, ВсІ-2, р53, ядерному фактору гепатоцитов-Іbеtа (HNF-1ß). Результаты исследования. В эпителии стенок эндометриоидных кист определялись синцитиальные папиллярные изменения (39,7%), метаплазия с клетками типа «сапожного гвоздя с большой шляпкой» (15,4%), в 41,0% случаев - атипия эпителия с колебанием экспрессии Ki-67 и Bcl-2 от низкой до относительно высокой, с низкой экспрессией р53. Экспрессия HNF-1ß в очагах без атипии выявлена в 56,3% случаев, а в очагах с фокусами атипии - в 94,7% и обнаружена только в светлоклеточных аденокарциномах. Заключение. Гиперэкспрессия HNF-1ß позволяет предположить адаптационный характер и гистогенетическую связь ЭЯ со светлоклеточными опухолями яичников.</p></trans-abstract><kwd-group xml:lang="en"><kwd>ovarian endometriosis</kwd><kwd>epithelial atypia of ovarian endometriosis</kwd><kwd>anti-hepatocyte nuclear factor-1ß (HNF-1ß)</kwd><kwd>clear cell adenocarcinoma of the ovary</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эндометриоз яичников</kwd><kwd>атипия эпителия эндометриоза яичников</kwd><kwd>ядерный фактор гепатоцитов-1Ьеґа (HNF-1ß)</kwd><kwd>светлоклеточная аденокарцинома яичников</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Jiang Q.Y., Wu R.J.
