Molar pregnancy is an abnormal growth of trophoblastic tissue in the uterus. It can be either complete or partial. In moles, development fetus absent, while partial moles contain gestational sac. Choriocarcinoma a malignant form that arise from molar tissue. Hydatiform mole and choriocarcinoma are rare complicated diseases with numerous pathological conditions lead to significant kidney damage....

Choriocarcinoma is a malignant gestational trophoblastic neoplasia (GTN) and one of the curable types of gynecological cancer. However, 10% of choriocarcinoma patients have a poor prognosis, particularly when they have metastasis, apart from pulmonary metastasis, or do not go into remission by the second chemotherapeutic regimen. We herein present the case of a 36-year-old patient who had chori...

The propensity of choriocarcinoma to metastasize to lungs, liver and brain is well known. Though theoretically metastases are possible to anywhere in the body, renal metastases are rare. A 56 year old Malay woman who had total abdominal hysterectomy in 1985 for molar pregnancy presented with haemoptysis and dyspnea in 1990. Examination showed she had choriocarcinoma with pulmonary and renal met...

Abstract Introduction: Maxillary canines commonly have an ectopic eruption. This study aimed to assess the factors related to the ectopic maxillary permanent canines. Materials and Methods:This was a descriptive cross-sectional study of 1357 panoramic radiographs from patients 8 to 13 years old. The radiography was excluded if the patient had any developmental disease or if the panoramic im...

The case history is presented of a patient which illustrates both the diagnostic difficulties of an extremely rare tumour (choriocarcinoma of the lung) and its associated haemorrhagic metastases ("choriocarcinoma syndrome"). (Thorax 1994;49:523-524) Department of Pneumology I Durieu P H Guillaud

This case demonstrates a rare event of retained invasive placenta masquerading as choriocarcinoma. The patient presented with heavy vaginal bleeding following vaginal delivery complicated by retained products of conception. Ultrasound and computed tomography demonstrated a vascular endometrial mass, invading the uterine wall and raising suspicion for choriocarcinoma. Hysterectomy revealed retai...

The human placenta arises from the zygote through single cell intermediates called cytotrophoblasts that in turn give rise to a syncytium. In culture, mononucleated cytotrophoblasts exhibit little, if any, cell division but are converted to ~ultinucleated cells. Choriocarcinoma, the malignant tumor of placenta trophoblast, comprises a mixed population of dividing cellular intermediates that res...

Brain-derived neurotrophic factor (BDNF) acts through its cognate receptor tyrosine kinase-B (TrkB) to regulate diverse physiological functions in reproductive and other tissues. In normal and malignant trophoblastic cells, the BDNF/TrkB signaling promotes cell growth. Due to the highly malignant nature of choriocarcinoma, we investigated possible involvement of this system in choriocarcinoma c...

A unique electrophoretic form of lactate dehydrogenase (LDH-Z), formerly observed in a choriocarcinoma cell line (JEG-3) and first-trimester placenta, has been shown to be the same as that produced in hydatidiform mole and term placenta. We have also observed LDH-Z in second-trimester placenta, choriocarcinoma metastasized to the liver, and five of five additional independently derived (from di...
