PSTTs occur in women of childbearing age and most of them have strong desire to preserve fertility. PSSTs are tumors with unpredictable biological behavior, high chemo-resistance and possibly fatal outcome in case of metastatic disease.</p><p>Hysterectomy is the primary treatment of choice in early disease.

Заболевание развивается у женщин репродуктивного возраста, большинство из которых на момент постановки диагноза нуждаются в сохранении фертильности. ТОПЛ характеризуется непредсказуемым биологическим поведением, малочувствительна к химиотерапии и характеризуется неблагоприятным прогнозом при диссеминации заболевания. При ранней стадии заболевания лечение начинают с хирургического этапа в объеме гистерэктомии. Мы представляем редкое клиническое наблюдение органосохраняющего лечения пациентки с ТОПЛ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>placental site trophoblastic tumor</kwd><kwd>fertility sparing treatment</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>опухоль плацентарного ложа</kwd><kwd>органосохраняющее лечение</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Kurman R.J., Scully R.E., Norris H.J.
