}} Germ cell tumours are neoplasmsderived from germ cells. In females, germ cell tumours account for 30% of ovarian tumours, but only 1 to 3% of ovarian cancersin North America. In younger women germ cell lesions are more common, thus in patients under the age of 21, 60% of ovarian tumours are of the germ cell type, and up to one-third are malignant. In males, germ cell tumours occur typically after puberty and are malignant (testicular cancer). Germ cell tumours may develop outside of the gonads.
