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 tumor is a very rare variant of gestational trophoblastic disease which differs histologically and immunocytochemically from gestational choriocarcinoma. The English language literature includes only 74 reported cases. Seventeen patients have been managed at Charing Cross Hospital with this diagnosis. The median follow-up is 4.6 years, and the 5-year overall surviva...

BACKGROUND Finding a tumor marker to predict the aggressive behavior of molar pregnancy in early stages has yet been a topic for studies. OBJECTIVES In this survey we planned to study patients with molar pregnancy to 1) assess the p53 and c-erbB-2 expression in trophoblastic tissue, 2) to study the relationship between their expression intensity and progression of a molar pregnancy to gestati...

Invasive mole also known as chorioadenoma destruens comprises about 15 % of all gestational trophoblastic neoplasia [1]. It is a trophoblastic tumor characterized by myometrial invasion by direct extension or through venous channels. The most common presenting symptom is vaginal bleeding (97 %) [2]. The diagnosis is usually suggested after a hydatidiform mole is removed and bhCG remains elevate...

The hydatiform mole is a gestational trophoblastic disease caused by abnormal gametogenesis and fertilization. The incidence is rare in our country. It seems to be encourage by poor nutrition in beta carotene, consanguinity, to early or to old maternal age, abortion history, endocrine problems, dysfunctions of genital organs, genital disorders. It is frequent between the 11th and 25th week of p...

Among 2,968 women and girls exposed to crocidolite (blue asbestos) at Wittenoom, three cases of choriocarcinoma and three cases of hydatidiform mole have been identified (crude incidence rate of 9.9 per 1000 women and 1.7 per 1000 deliveries for choriocarcinoma and hydatidiform mole, respectively). The women with choriocarcinoma were resident at Wittenoom at the time of disease development, whe...

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 ...
