Why is it called embryonal carcinoma?

What is an embryonal carcinoma?

Embryonal carcinoma is a type of testicular cancer, which is cancer that starts in the testicles, the male reproductive glands located in the scrotum. It most often develops in young and middle-aged men. It tends to grow rapidly and spread outside the testicle.

Is embryonal carcinoma rare?

Embryonal carcinoma is a rare type of nonseminomatous germ cell tumor occurring in the mediastinum of young males, as either a pure or a mixed form. It is often associated with teratoma (i.e. teratocarcinoma), choriocarcinoma, or seminoma.

Is embryonal carcinoma genetic?

Embryonal carcinoma was found to have a six-gene signature which was detected in 3 of 5 studies and included DNMT3B, DPPA4, GAL, GPC4, POU5F1, and TERF1. All six genes play important roles in embryonic development and pluri-potency, which is the evidence that embryonic carcinoma resembles inner cell mass.

What is the most aggressive testicular tumor?

A rapidly growing and aggressive tumor, which occurs in about 40 percent of nonseminomatous germ cell tumors. Yolk sac carcinoma. The most common type of testicular tumor in children, but it’s rare in adults.

How does embryonal carcinoma occur?

Embryonal carcinoma has cancer cells that usually mix with another type of germ cell tumor. For example, embryonal carcinoma cells could mix with a teratoma and make it cancer. Choriocarcinoma is a rare cancer that happens in the placenta. It can affect both the mother and baby.

Is germ cell tumor inherited?

The cause of germ cell tumors isn’t fully known. Some gene defects passed on from parents to children (inherited) may increase the risk for germ cell tumors. Some genetic syndromes can cause abnormal growth of the male and female reproductive systems.

What is the choriocarcinoma?

(KOR-ee-oh-KAR-sih-NOH-muh) A malignant, fast-growing tumor that develops from trophoblastic cells (cells that help an embryo attach to the uterus and help form the placenta). Almost all choriocarcinomas form in the uterus after fertilization of an egg by a sperm, but a small number form in a testis or an ovary.
