BACKGROUND Choriocarcinoma of the ovary is rare. This tumor can arise from gestational tissue or pure germ cells of the ovary, the former results in gestational choriocarcinoma. The clinical characteristics and histology of both tumor types are identical, differentiation of these tumors is necessary for effective treatment. One strategy for the differentiation of these tumors types is to identi...

The kinesin protein Kif7 has been recognized as an integral component of hedgehog signalling. Aberrant activation of hedgehog signalling has been implicated in many human solid tumours. Gestational trophoblastic disease includes frankly malignant choriocarcinoma and potentially malignant hydatidiform mole. Here we investigated the hedgehog signalling components expression profiles in gestationa...

Tumours of the fallopian tube are much less common than the corresponding ovarian neoplasms; however, histologically the same surface epithelial-stromal tumour subtypes are recognized. Sex cord-stromal and germ cell tumours are rare. H y d a t i d i f o rm moles and gestational choriocarcinoma are uncommon complications of tubal ectopic pregnancy. The wolffian adnexal tumour is also infrequent ...

Paper electrophoresis of the oligosaccharide fraction obtained by hydrazinolysis of human chorionic gonadotropin (HCG), which was purified from the urine of two patients with invasive mole, gave fractionation patterns different from those of normal and hydatidiform mole HCGs. Structural study of the oligosaccharides in each fraction revealed that the triantennary complex-type asparagine-linked ...

Received 7 August 2005 Accepted 5 March 2006 The placenta is unique amongst normal tissues in transcribing numerous different human endogenous retroviruses at high levels. In this study, RT-PCR and immunohistochemistry were used to investigate the expression of syncytin in human trophoblast. Syncytin transcripts were found in first-trimester trophoblast cells with both villous and extravillous ...

Background: Choriocarcinoma is a rare highly malignant trophoblastic neoplasm. It can be preceded by any form of gestation including a complete or a partial mole, miscarriage and normal pregnancy. Simultaneous intraplacental choriocarcinoma involving both mother and infant is extremely rare. Hepatomegaly, anemia, elevated ßHCG is the diagnostic triad. Here we report a 6 weeks old Afghan girl in...

Choriocarcinoma is the most aggressive, malignant form of gestational trophoblastic disease and has varying incidence, increasing in patients older than 40 years. It usually develops after a malignant alteration in a molar pregnancy, but rarely after an abortion or normal or ectopic pregnancies. The most common localization is the uterus, but it can also be found rarely in the ovaries, fallopia...

Intraplacental choriocarcinoma is a rare malignant tumor diagnosed after an abortion, an ectopic pregnancy, or a term or preterm pregnancy or following the diagnosis of a hydatidiform mole. During pregnancy, it may be more common than reported, as most patients are asymptomatic and placental choriocarcinomas are usually inconspicuous macroscopically and are often mistaken for an infarct. Based ...
