Placental site trophoblastic tumor (PSTT) is a highly rare form of gestational trophoblastic diseases that arise from intermediate trophoblastic cells. By presenting this case, we aimed to review the treatment and diagnosis, approach to PSTT. 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 c...
