•Histologic morphology is frequently equivocal for PSTTs.•Histology combined with immunohistochemical staining was necessary to make the diagnosis.•PSTT confined to the uterus was successfully treated with surgery alone.

Here we report a case of a placental site trophoblastic tumor in a 36 year old Chinese woman, 31 months following a prior normal pregnancy. Her clinical presentation and ultrasound findings were uncharacteristic; and the final definitive diagnosis was established based on histological examination in conjunction with immunohistochemistry studies and a normal beta human chorionic gonadotropin lev...

Introduction: Gestational trophoblastic disease (GTD) includes hydatiform mole, choriocarcinoma, placental site tumor, and epithelial tumor. Also, molar pregnancy can happen as an ectopic pregnancy. The coincidence of these complicated pregnancies seems to occur extremely rarely. Case presentation: Here, we presented a 26-year-old woman, nulli gravida with the first presentation intrauterine co...

The patient presented initially with abdominal pain with, fever, bleeding and pelvic mass on ultrasonography leading to the wrong diagnosis abscess. Dilation curettage were performed pathological examination confirmed diagnosis. Therefore, she underwent hysterectomy. Four years after surgery, is still di...

Introduction: Placental teratoma is an uncommon, non-trophoblastic benign tumor. Since the first description of this type tumor by Morvilli in 1925, only a few cases abnormality have been diagnosed and reported. Case presentation: We describe here 35-year-old pregnant woman admitted for elective cesarean section. The placenta membranes were delivered spontaneously. After delivering placenta, ma...

Chorangiocarcinoma is an extremely rare primary placental neoplasm, with only five cases reported in the literature (Table 1). Some researchers considered it as a bona fide chorangiocarcinoma, but most cases described a chorangioma with abnormal trophoblastic proliferation. In spite of atypia in cytology, marked mitosis and tumor necrosis, chorangiocarcinoma was always reported benign. No metas...

BACKGROUND: Placental site trophoblastic tumor (PSTT) is a rare and unique form of gestational trophoblastic disease (GTD). This tumor represents a neoplastic transformation of intermediate trophoblastic cells. We document a case of long term remission in a patient with metastatic PSTT. CASE PRESENTAION: A 27-year-old patient with metastatic PSTT was treated with combination therapy (chemothera...
