==Classification==
- Childhood Extracranial Germ Cell Tumors classification
- 1. GCTs arise from primordial germ cells, which migrate during embryogenesis from the yolk sac through the mesentery to the gonads.[4,5] Childhood extracranial GCTs can be divided into the following two types:
- Gonadal.
- Extragonadal.
- 2. Most childhood extragonadal GCTs arise in midline sites (i.e., sacrococcygeal, mediastinal, and retroperitoneal); the midline location may represent aberrant embryonic migration of the primordial germ cells.
- Childhood extracranial GCTs are broadly classified as the following:
- Mature teratomas.
- Immature teratomas.
- Malignant GCTs.
- GCTs comprise a variety of histologic diagnoses and can also be divided into the following histologic types:
- Germinoma.
- Germinoma.
- Dysgerminoma (ovary).
- Seminoma (testis).
- Nongerminoma.
- Teratoma (mature and immature).
- Yolk sac tumor (endodermal sinus tumor).
- Choriocarcinoma.
- Embryonal carcinoma.
- Gonadoblastoma.
- Mixed GCT
