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. ...

early recognition of gestational trophoblastic neoplasm (gtn) will maximize the chances of cure with chemotherapy but some patients present with many different symptoms months or even years after the causative pregnancy making diagnosis difficult. clinicians should be aware of the possibility of gtn in any reproductive age woman with bizarre central nervous system, gastrointestinal, pulmonary s...

Gestational trophoblastic neoplasms are malignant lesions that arise from placental villous and extravillous trophoblast. Four clinicopathologic conditions make up this entity: invasive mole (IM), choriocarcinoma (CCA), placental-site trophoblastic tumor (PSTT), and epithelioid trophoblastic tumor (ETT). IM and CCA, which make up the majority of these tumors, are highly responsive to chemothera...

Placental site trophoblastic tumour (PSTT) is a rare form of trophoblastic disease accounting for < 2% of all gestational trophoblastic neoplasms. Most of the cases follow a normal pregnancy and a small number have a preceeding molar pregnancy or spontaneous abortion. It can occur as early as several weeks or as late as 15 years after normal delivery, molar pregnancy or abortion. Excessive inte...

A discussion of the classification of tro­ phoblastic neoplasms with clinical scien­ tists is of importance, for the work of those who direct pathology, biochemistry, en­ docrine and hematology laboratories is essential in the diagnosis and manage­ m ent of these neoplasms. Proper therapy requires the correct histopathologic diag­ nosis, monitoring of marrow, renal and marrow function and, m os...

From the published data, the present mini-review attempts to answer two fundamental questions about the gestational trophoblastic neoplasms. In addition, it extrapolates the findings to other cancers that produce small amounts of hCG and how a novel therapies could be developed.

An epithelioid trophoblastic tumor (ETT) is a form of gestational trophoblastic neoplasms that arise from trophoblasts. The tumor generally occurs in women of reproductive age and has a characteristic growth pattern and immunohistochemical profile. We present an extremely rare case of a primary ETT occurring in the lungs with an adenocarcinoma in the contralateral lung as synchronous double pri...
