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...

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.

Gestational trophoblastic neoplasms (GTNs) are a rare group of neoplastic diseases composed of choriocarcinomas, placental site trophoblastic tumors (PSTTs) and epithelioid trophoblastic tumors (ETTs). Since these tumors are derivatives of fetal trophoblastic tissue, approximately 50% of GTN cases are expected to originate from a male conceptus and carry a Y-chromosomal complement according to ...

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...

Molar pregnancy is a gestational trophoblastic disease that belongs to the category of precancerous lesions. On the other end of the spectrum are gestational trophoblastic neoplasms such as invasive mole, choriocarcinoma, placental site trophoblastic tumor and epithelioid trophoblastic tumor, which are considered malignant tumors. Based on defined histopathological criteria, molar pregnancy is ...

Gestational trophoblastic neoplasms (GTN) are proliferative degenerative disorders of placental elements and include complete or partial mole (90%), invasivemole (5-8%), choriocarcinoma (1-2%) and placental site tumor (1-2%). Chorioadenoma destruens is a trophoblastic tumor, characterized by myometrial invasion through direct extension or via venous channels. We present a case of invasive mole ...

Objective: To investigate clinicopathological characteristics of unusual gestational trophoblastic neoplasms (GTNs) that are difficult to be clearly classified. Methods: We retrospectively reviewed 455 GTNs treated and found three unusual cases. We investigated the morphology and immunostains of all three cases. Results: The three patients aged 25-42 years, the interval from the last gestation ...

Epithelioid trophoblastic tumor (ETT) is a rare gestational trophoblastic neoplasm composed of intermediate trophoblasts. Most cases of ETT are reported in women of reproductive age following a prior gestation within 2 weeks to 30 years. ETT is extremely rare in postmenopausal women. It is commonly misdiagnosed as a poorly differentiated carcinoma or another type of gestational trophoblastic tu...

UNLABELLED Placental site nodules (PSNs) and epithelioid trophoblastic tumors (ETTs) respectively represent non-neoplastic and neoplastic lesions of chorionic-type intermediate trophoblasts (ITs). Many patients with a PSN have a history of a cesarean section (CS) or therapeutic abortion. Recent evidence shows that a PSN may progress to an ETT. Herein, we describe a coexisting ETT and placental ...
