Extrauterine epithelioid trophoblastic tumors constitute an extremely rare gestational trophoblastic disease. We report the case of an extrauterine trophoblastic tumor that was incidentally detected in the left lung. Squamous cell carcinoma was suspected after microscopically examining the specimen obtained upon preoperative needle biopsy. After surgery, the tumor was confirmed by microscopic f...

an invasive mole is a rare form of gestational trophoblastic disease in which the molar tissue invades into the deep myometrium, cervical stroma, blood vessels or extrauterine sites. this report is of an invasive mole of spleen that has originated from an ectopic pregnancy, which was primarily though to be a choriocarcinoma.

( Obstet Gynecol . 2021;137:355–370) Gestational trophoblastic disease (GTD) refers to rare processes originating from the placenta that require timely and appropriate management. GTD includes partial or complete hydatidiform moles (HM), as well severe gestational neoplasia (GTN) related tumors. Obstetrician-gynecologists are more likely be involved in care of women with HM who have unclear dia...

placental site trophoblastic tumor (pstt) is a very rare variant of gestational trophoblastic tumor. it can occur after normal termination of pregnancy or spontaneous abortion and ectopic or molar pregnancy. there is a wide range of clinical manifestations from a benign condition to an aggressive disease with fatal outcome. one of the most important characteristics of pstt, unlike other forms o...

Gestational trophoblastic neoplasia (GTN) describes a heterogeneous group of interrelated lesions that arise from abnormal proliferation of placental trophoblasts. GTN lesions are histologically distinct, malignant lesions that include invasive hydatidiform mole, choriocarcinoma, placental site trophoblastic tumor (PSTT) and epithelioid trophoblastic tumor (ETT). GTN tumors are generally highly...

OBJECTIVES: Doppler ultrasonography can be used to assess neoangiogenesis, a characteristic feature of postmolar gestational trophoblastic neoplasia. However, there is limited information on whether uterine artery Doppler flow velocimetry parameters can predict gestational trophoblastic neoplasia following a complete hydatidiform mole. The purpose of this study was as follows: 1) to compare ute...

The reported incidence of gestational trophoblastic disease is 1-2:1000 pregnancies. The disease includes a) hydatidiform mole (partial and complete), b) invasive mole, c) choriocarcinoma and d) placental site trophoblastic tumors. Current management is based on several prognostic risk factors. We describe an interesting case of a 51-year–old woman who presented with abnormal vaginal bleeding a...

Gestational trophoblastic disease (GTD) is characterized by abnormal proliferation of pregnancy-associated trophoblastic tissue with malignant potential. GTD covers a spectrum of tumors and tumor-like conditions and may occur in a benign form as hydatiform mole or as malignancy in the form of invasive mole or choriocarcinoma. GTD has become a curable malignant disease since the introduction of ...

Gestational trophoblastic disease associated with ectopic pregnancy is a rare event and persistent trophoblastic disease is a well recognized complication of conservative surgical treatment for ectopic pregnancy but rarely secondary trophoblastic implantation may occur after salpingectomy. This is a case report of a rare and unusual presentation of persistent trophoblastic implantation followin...
