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...

Gestational trophoblastic disease (GTD) is a spectrum of cellular proliferations arising from the placental villous trophoblasts encompassing four main clinicopathologic forms : hydatidiform mole (complete and partial), invasive mole, choriocarcinoma and placental site trophoblastic tumor (PSTT). Placental site trophoblasic tumours (PSTT) are rare and usually diagnosed after dilatation and cure...

Epithelioid trophoblastic tumor (ETT) is a rare trophoblastic tumor originating from chorionic-type intermediate trophoblasts (ITs). It is usually associated with a prior gestational event. We present a 44-year-old woman who had unusual pregnancy related history. The patient received her second spontaneous abortion at the age of 25 years and had suffered from choriocarcinoma in left board ligam...

Gestational trophoblastic disease (GTD) is a group of conditions that originate from the abnormal hyperproliferation of trophoblastic cells, which derive from the trophectoderm, the outer layer of the blastocyst that would normally develop into the placenta during pregnancy. GTDs encompass hydatidiform mole (HM) (complete and partial), invasive mole, gestational choriocarcinoma, placental-site ...

Gestational trophoblastic neoplasms are a group of fetal trophoblastic tumors including choriocarcinomas, epithelioid trophoblastic tumors (ETTs), and placental site trophoblastic tumors (PSTTs). Mixed gestational trophoblastic neoplasms are extremely rare. The existence of mixed gestational trophoblastic neoplasms that were composed of choriocarcinoma and/or PSTT and/or ETT was also reported. ...

Placental site trophoblastic tumor (PSTT) is a rare type of gestational trophoblastic neoplasia (GTN). It is rising from the abnormal proliferation of intermediate trophoblastic cells with occasional multinuclear giant cells, with the potential for local invasion and metastasis. For its untypical and changeable clinical characteristics, the diagnosis and management are still poorly understood. ...

background: gestational trophoblastic neoplasia (gtn) is a curable disease thatinvolves the development of malignant tumor in the woman after a normal or molarpregnancy. the position of surgery in gtn is not properly specified and is changingdue to new chemotherapy protocols. however, the role of surgery is highlighted inchemotherapy-resistant gtn. other indications of surgery in trophoblastic ...
