Embryonal carcinoma: A malignant germ cell tumor that occurs most often in the testes and accounts for about 40% of testicular tumors. Under the microscope, these tumors may resemble tissues of early embryos.

embryonal carcinoma
Embryonal carcinoma cells are malignant cells that are usually mixed with other types of germ cell tumors. They occur most often in the testes. These types of cells have the ability to spread to other parts of the body.

The histologic types of germ cell tumors include GERMINOMA, TERATOMA (mature, immature, and with malignant transformation), YOLK SAC TUMOR, EMBRYONAL CARCINOMA, and CHORIOCARCINOMA. No WHO histologic grades are available for these types of tumors.

The most common types of testicular cancers are seminomas and nonseminomas (teratoma, choriocarcinoma, embryonal carcinoma, or yolk sac tumor), which develop from the cells. Each type grows, spreads, and is treated differently.

A stromal tumor is a rare type of testicular tumor. Such tumors are usually not cancerous. The two main types of stromal tumors are Leydig cell tumors and Sertoli cell tumors.

Nonseminomas are a group of cancers that sometimes occur in combination, including choriocarcinoma, embryonal carcinoma, and yolk sac tumors. Nonseminomas arise from more mature, specialized germ cells and tend to be more aggressive than seminomas.

Nonseminoma. This group of cancers includes choriocarcinoma, embryonal carcinoma, teratoma and yolk sac tumors. These types of cancer tend to develop earlier in life than seminomas, usually occurring in men between their late teens and early 40s.

Nonseminomas can be further classified as embryonal carcinomas, malignant teratomas, endodermal sinus tumors, choriocarcinomas or mixed germ cell tumors. The specific type of germ cell tumor influences both treatment and prognosis.

Nonseminomas are actually a group of cancers and comprise 60 percent of cases. They include choriocarcinoma, embryonal carcinoma, teratoma, and yolk sac tumors.

Elevated alpha-fetoprotein levels are also found in certain ovarian and teratocarcinoma or embryonal carcinoma of the testis. Elevated alpha-fetoprotein levels are not found in other histologies of testicular cancer. Normal range: Adults: <15 ng/ml.

During surgery, there is about a 45% chance that only scar tissue will be found, a 45% chance there will be teratoma, and about a 10% chance of some other type of germ cell tumor (for example, embryonal carcinoma, seminoma, yolk sac tumor, ...

Nonseminomas include embryonal carcinoma, teratoma, choriocarcinoma, and yolk sac tumor.

Thus, these tumors often are "mixed," that is, they are made up of more than one tumor type. Typical components include choriocarcinoma, embryonal carcinoma, immature teratoma, and yolk sac tumors.

Nonseminoma (non-sem-i-NO-ma): A classification of testicular cancers that arise in specialized sex cells called germ cells. Nonseminomas include embryonal carcinoma, teratoma, choriocarcinoma, and yolk sac tumor.

α-Fetoprotein, a normal product of fetal liver cells, is also present in the sera of patients with primary hepatoma, nonseminomatous germ cell tumors, and, frequently, ovarian or testicular embryonal carcinoma.

non-seminoma A group of testicular cancers that begin in the germ cells (cells that give rise to sperm). Nonseminomas are identified by the type of cell in which they begin and include embryonal carcinoma, teratoma, ...

Seminomas may be one of three types: classic, anaplastic, or spermatocytic. Types of nonseminomas include choriocarcinoma, embryonal carcinoma, teratoma, and yolk sac tumors. Testicular tumors may contain both seminoma and nonseminoma cells.

Seminomas start in the cells that make sperm. Nonseminomas are a group of cancers that include choriocarcinoma, embryonal carcinoma, teratoma, and yolk sac tumors. A testicular cancer may have a combination of both types.

A group of testicular cancers that begin in the germ cells (cells that give rise to sperm). Nonseminomas are identified by the type of cell in which they begin and include embryonal carcinoma, teratoma, choriocarcinoma, and yolk sac carcinoma.

Nonseminomas are identified by the type of cell in which they begin and include embryonal carcinoma, teratoma, choriocarcinoma, and yolk sac carcinoma.
