Gestational trophoblastic tumor (GTT) most commonly follows a molar pregnancy. In fact, it can occur following gestational events such as induced or spontaneous abortion, ectopic pregnancy, and term pregnancy. In this study, we present the case of a patient with ectopic pregnancy who was treated with a single dose of methotrexate (MTX). The maximum titer of beta subunit of human chorionic gonad...

The objective of this study was to evaluate the distribution of choriocarcinoma-like human chorionic gonadotrophin (HCG) isoforms during first trimester pregnancy and their relationship with in-vitro HCG bioactivity. This was done by means of a retrospective analysis of patients' sera with first trimester normal intrauterine and abnormal (ectopic) pregnancies. Serum samples were obtained from 3...

Gestational trophoblastic diseases (GTD) are a heterogenous group of disorders that arise from trophoblastic epithelium. They can follow molar pregnancy (50%), abortions (25%), normal pregnancy (22.5%), and ectopic pregnancy (2.5%) [Robert JK, Lora HE, Brigitte MR (ed) Blaustein Pathology of the Female Genital Tract 6th edn (Springer) pp. 1101-7]. Occurrence of choriocarcinoma following normal ...

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 phenotypes and also in the JAR and JEG-3 chor...

Haemoperitoneum in women of reproductive age usually suggests either ruptured ectopic pregnancy or ruptured ovarian cysts. Metastatic choriocarcinoma is considered the least common cause of haemoperitoneum in women of childbearing age. We report a rare case of pancreatic and hepatic metastasis of choriocarcinoma in a young, 30-year-old female who had delivered 10 months prior at term gestation ...

Choriocarcinoma of the ovary is a rare and highly malignant germ cell tumor. There are three ways in which an ovarian choriocarcinoma can arise: as a primary gestational choriocarcinoma that results from an ectopic ovarian pregnancy, as a metastatic choriocarcinoma that arises from a gestational choriocarcinoma, and as a germ cell tumor with differentiation into trophoblastic structures. Ovaria...

Structural analysis of the sugar chains of human chorionic gonadotropin (hCG) has revealed that abnormal biantennary structures appear specifically on hCG in the urine of choriocarcinoma patients. However, the enzymatic and molecular mechanisms of the biosynthesis of abnormal biantennary sugar chains have not yet been elucidated. In this report, the enzyme activities and the expression levels o...
