Choriocarcinoma

Choriocarcinoma is a rare, highly malignant form of germ cell tumor. It is a form of cancer that develops in the tissue that normally forms the placenta. It usually starts in the cells that form the chorion, which is a layer of the placenta that helps protect and nourish the fetus during pregnancy. Choriocarcinoma can spread rapidly and spread to other parts of the body. It is most likely to spread to the lungs, liver, brain, and bones, although it can spread to other organs. Symptoms of choriocarcinoma include: • Abnormal vaginal bleeding • Abdominal or pelvic pain • Rapid weight loss • Swelling of the abdomen • Unusual fatigue • Fever • Nausea or vomiting Diagnosis of choriocarcinoma is usually made through a combination of imaging tests such as ultrasound, CT scan, MRI, and a biopsy. Treatment typically involves chemotherapy, radiation therapy, and/or surgery. In some cases, it may be possible to remove the tumor with surgery alone.
