Цель: обратить внимание специалистов на возможность чистой негестационной хориокарциномы яичников имитировать внематочную яичниковую беременность. Представлена история болезни пациентки с диагностированной негестационной формой хориокарциномы яичника, имитировавшей внематочную беременность, зафиксированная в 3 гинекологическом отделении ГБУЗ Республики Мордовия «РКБ №4» (г. Саранск). Наше клиническое наблюдение дополняет уже известные знания по поводу этого редкого заболевания и, таким образом, мы надеемся, что полученная информация будет являться дополнительным поводом для повышения уровня медицинской настороженности в плане диагностики данного заболевания.</p></abstract><trans-abstract xml:lang="en"><p>Non-gestational ovarian choriocarcinoma is an exceptionally rare malignant germ cell tumor characterized by a particularly aggressive course, difficult diagnosis, and the inability to predict outcomes at the early stages of the disease. Objective: To draw the attention to the possibility of pure non-gestational ovarian choriocarcinoma mimicking an ectopic ovarian pregnancy. We present the case history of a patient with diagnosed non-gestational ovarian choriocarcinoma mimicking ectopic pregnancy, recorded in the 3rd gynecological department of the State Budgetary Healthcare Institution of the Republic of Mordovia "Republican Clinical Hospital № 4" (Saransk). Our clinical observation adds to the already known information about this rare disease and, thus, we hope that the information provided will be an additional reason to increase the level of medical vigilance in terms of diagnosis of this disease.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гинекология</kwd><kwd>онкология</kwd><kwd>трофобластическая болезнь</kwd><kwd>опухоль яичников</kwd><kwd>хориокарцинома</kwd><kwd>негестационная хориокарцинома яичников</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gynecology</kwd><kwd>oncology</kwd><kwd>trophoblastic disease</kwd><kwd>ovarian tumor</kwd><kwd>choriocarcinoma</kwd><kwd>non-gestational ovarian choriocarcinoma</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Гинекология.
