Which marker is most useful for detection of gestational trophoblastic disease?
The β-hCG level is used to diagnose gestational trophoblastic disease, a rare neoplastic complication of pregnancy.
How is GTD diagnosed?
Doctors can often be fairly certain of a diagnosis of GTD based on symptoms, blood test results7, and imaging tests, but the diagnosis is often made after a procedure called a D&C (dilation and curettage) in patients with abnormal bleeding. The cells from the tissue removed during the D&C are viewed under a microscope.
What is Rauber cell?
‘Cells of Rauber’ are trophoblast cells that are in contact with the inner mass of blastocyst. The blastocyst is a structure formed in the stages of easy development of mammals. If it possesses an inner mass and cell which forms an embryo. The outer layer of blastocyst consists of cells that are known as trophoblast.
What do you need to know about gestational trophoblastic disease?
1 Gestational trophoblastic disease is the name given to a group of tumors that form during abnormal pregnancies. 2 GTD is rare, affecting about one in every 1,000 pregnant women in the U.S. 3 While some GTD tumors are malignant (cancerous) or have the potential to turn cancerous, the majority are benign (noncancerous).
What are the different types of trophoblastic disease?
Gestational trophoblastic disease (GTD) is a general term that includes different types of disease: Complete HM. Partial HM. Invasive moles. Choriocarcinomas. Placental-site trophoblastic tumors (PSTT; very rare). Epithelioid trophoblastic tumors (ETT; even more rare).
How are the trophoblast cells affected in GTD?
The trophoblast helps the embryo implant itself to the uterine wall. These cells also form a large part of the tissue that make up the placenta — the organ that supplies nutrients to a developing fetus. In GTD, there are abnormal changes in the trophoblast cells that cause tumors to develop.
Where does a placental-site trophoblastic tumor ( pstt ) form?
Placental-site trophoblastic tumors. A placental-site trophoblastic tumor (PSTT) is a rare type of gestational trophoblastic neoplasia that forms where the placenta attaches to the uterus. The tumor forms from trophoblast cells and spreads into the muscle of the uterus and into blood vessels.
