Doctor's Notes on Childhood Extracranial Germ Cell Tumors

Childhood extracranial germ cell tumors form from germ cells in parts of the body other than the brain. A germ cell forms as a fetus develops and later becomes sperm in the testicles or eggs in the ovaries. Sometimes while the fetus is forming, germ cells travel to parts of the body where they should not be and grow into a germ cell tumor that may form before or after birth. The three types of extracranial germ cell tumors are:
