Germ cell tumors develop in the egg-producing cells of the ovary, and comprise about 5% of ovarian tumors.

What are choriocarcinomas the result of?

Choriocarcinomas result from genetic damage to a germ cell. Males with Klinefelter syndrome are especially likely to develop extragonadal germ cell tumors.


What is a mixed germ cell tumor?

Germ cell tumors are malignant (cancerous) or non-malignant (benign, non-cancerous) tumors that are comprised mostly of germ cells. Germ cells are the cells that develop in the embryo (fetus, or unborn baby) and become the cells that make up the reproductive system in males and females. These germ cells follow a midline path through the body after development and descend into the pelvis as ovarian cells or into the scrotal sac as testicular cells. Most ovarian tumors and testicular tumors are of germ cell origin. The ovaries and testes are called gonads. They are rare, as only about 2.4 children in one million will develop one of these tumors in a given year. Germ cell tumors account for 4 percent of all cancers in children and adolescents under the age of 20 years. Germ cell tumors can spread (metastasize) to other parts of the body. The most common sites for metastasis are the lungs, liver, lymph nodes, and central nervous system. Rarely, germ cell tumors can spread to the bone, bone marrow, and other organs. 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. When these cells are mixed with an otherwise benign type of tumor (mature teratoma), the presence of embryonal carcinoma cells will cause it to become malignant (cancerous).

What is tumor of the testicle medical term?

The medical term for a tumor of the testicle is "testicular tumor." These tumors can be classified into two main types: germ cell tumors, which originate from the reproductive cells, and non-germ cell tumors, which arise from other types of testicular tissue. Testicular tumors can be benign or malignant, with germ cell tumors being the most common and often affecting younger men. Early diagnosis and treatment are crucial for favorable outcomes.


What is the icd-9 code for germ cell carcinoma?

The ICD-9 code for germ cell carcinoma is 186. It's important to note that this code is used for malignant neoplasms of the testis, which includes germ cell tumors. For more specific types of germ cell tumors, additional codes may be applicable; however, 186 serves as the general classification for this type of cancer in the ICD-9 coding system.


In what cells do testicular cancer arise?

Testicular cancer primarily arises from germ cells, which are the cells responsible for producing sperm. The two main types of testicular germ cell tumors are seminomas and non-seminomas. Additionally, testicular cancer can also originate from other cell types, such as Leydig cells and Sertoli cells, but these are less common. Overall, germ cell tumors account for the majority of testicular cancer cases.

Most common type of testicular cancer in males over 15 and under 40?

Most cases (95 percent) of testicular cancer originate in undeveloped cells (germ cells) that produce sperm.These tumors, called germ cell tumors (GCTs), are most common in men between the ages of 20 and 40 and are curable more than 95 percent of the time. There are two main types of GCTs: seminomas and nonseminomas. A third type, called stromal tumors, develops in the supporting tissues of the testicle.Testicular cancer may also develop in the supportive, hormone-producing tissue of the testicles (stroma). This type accounts for 4 percent of testicular cancer in men and 20 percent of cases in boys.Types of stromal tumors include Leydig cell tumors and Sertoli cell tumors.

What is the medical term meaning germ or sex cell?

A gamete is the same thing as the sperm and the egg. It comes from the Greek word meaning spouse. When the two gametes get together, they form a zygote, which will develop into a new individual.
