By presenting this case, we aimed to review the treatment and diagnosis, approach to PSTT.<br />A 31-year-old (G2P1A1L1) patient had abnormal vaginal bleeding. Serum ß-HCG was 5.82 mIU/ml and the transvaginal USG detected a polypoid mass in uterine cavity. Probe curettage was performed. Histopathologic specimens were confirmed as PSTT. No metastasis was detected. A total abdominal hysterectomy was performed.<br />PSTT is a rare tumor. In contrast to other trophoblastic tumors, PSTT produces a small amount of ß-HCG and it is relatively insensitive to chemotherapy. Adjuvant chemotherapy is suggested to follow surgical treatment in the cases with metastasis.</p>}, number={3}, journal={Gynecology Obstetrics & Reproductive Medicine}, author={Tunç, Senem Yaman and Ağaçayak, Elif and İçen, Mehmet Sait and Başaranoğlu, Serdar and Evsen, Mehmet Sıddık and Avcı, Yahya and Urakcı, Zuhat and Gül, Talip}, year={2016}, month={Dec.}, pages={171–173} }
