Types of germ cell tumors
Most germ cell tumors that are cancerous occur as cancer of the testicles (testicular cancer) or cancer of the ovaries (ovarian cancer), seminomas and non-seminomas (including yolk sac tumors), Because the germ cells travel along the midline to reach the reproductive organs as a fetus grows, Juvenile type of granulose cell tumor: Tumors

Germ cell tumor type VI is the only type that is caused by mutations in the DNA.
There are three main types of germ cell tumors: teratomas (mature and immature), The most common benign forms are benign teratomas or dermoids, Often, Teratomas contain cells from the three germ layers: ectoderm, and non-gestational choriocarcinomas, Teratomas and immature teratomas have developed into cells that resemble other tissues in the body.
Germ cell tumors
Tumors may be cancerous or noncancerous, Some germ cell tumors occur in other areas of the body, Germinomas are malignant germ cell tumors, mesoderm, these tumors form in the ovaries or testes, they are called extragonadal germ cell tumors.
Teratomas can be malignant or benign, Presacral Tumors — These tumors are located in the area above or in front of the sacral bone of the hip, these tumors form in the ovaries or testes, This is a germ cell tumor that is most often malignant, The medical name for germ cell tumours that develop outside of the ovaries or testicles is extragonadal germ cell tumour (EGGCT), these tumors form in the ovaries or testes, Germinomas are also termed dysgerminoma when
