What is Polyembryoma?
Polyembryoma is a type of tumor that develops from the cells of the gonads (testes in men or ovaries in women). Such tumors are called germ cell tumors.
What is Dysgerminoma ovary?
(DIS-jer-mih-NOH-muh) A type of cancer that begins in germ cells in females. Germ cells are cells that form sperm in males or eggs in females. Dysgerminomas occur most often in the ovaries, but they may also occur in other areas of the body, including the central nervous system.
Can dysgerminoma be benign?
Dysgerminoma: This is the most common type of malignant ovarian germ cell tumor. Mature teratoma (dermoid cyst or ovarian cyst): This is the most common type of benign ovarian germ cell tumor. These noncancerous tumors usually grow in teenage girls and young women.
What is a Gonadectomy?
Laparoscopic gonadectomy is an operation to remove the gonads. These are the organs that develop into either ovaries or testes, or even a combination of both. Normally there are two gonads, one on either side. They can be found inside the abdomen or in the groin.
Is Gonadoblastoma a germ cell tumor?
Gonadoblastoma. Gonadoblastoma is a mixed germ cell tumor with undifferentiated cells and is most frequently observed in female children, 1/3 of whom are younger than 15 years of age. This tumor was first described by Scully (20).
Is yolk sac tumors curable?
Yolk sac tumors can be cured if treated in the early stages. Patients need to be able to do self-examination and need to be educated about the successful management of the early disease.
Is dysgerminoma malignant?
Dysgerminoma: This is the most common type of malignant ovarian germ cell tumor.
What is seminoma and nonseminoma?
Seminomas are very sensitive to radiation therapy. Nonseminoma: This more common type of testicular cancer tends to grow more quickly than seminomas. Nonseminoma tumors are often made up of more than one type of cell, and are identified according to these different cell types: Choriocarcinoma (rare) Embryonal carcinoma.
What is the tumor marker for dysgerminoma?
The standard workup for suspected dysgerminomas includes the following tumor markers: Lactate dehydrogenase (LDH) Beta-human chorionic gonadotropin (beta-hCG) Alpha-fetoprotein (AFP)
What is prophylactic Gonadectomy?
Prophylactic gonadectomy has been recommended in complete androgen insensitivity syndrome (CAIS) because of an increased risk for the development of malignant germ cell tumors in the intra-abdominal gonads. No reliable screening parameters are available to detect early (pre-)malignant changes.
What is testicular feminization syndrome?
Testicular feminization. Androgen insensitivity syndrome (AIS) is when a person who is genetically male (who has one X and one Y chromosome) is resistant to male hormones (called androgens). As a result, the person has some of the physical traits of a woman, but the genetic makeup of a man.
What is Arrhenoblastoma?
Listen to pronunciation. (uh-REE-noh-blas-TOH-muh) A rare type of ovarian tumor in which the tumor cells secrete a male sex hormone. This may cause virilization (the appearance of male physical characteristics in females).
