Germ cell tumours are neoplasms derived from germ cells. In females, germ cell tumours account for 30% of ovarian tumours, but only 1 to 3% of ovarian carcinomas in 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.




Benign
  • Mature teratoma- the most common variant is the dermoid cyst, or benign cystic teratoma, a common ovarian neoplasm, typically not cancerous.


Malignant
  • Immature teratoma

  • Dysgerminoma

  • Yolk sac tumour (Endodermal sinus tumor)

  • Embryonal carcinoma

  • Polyembryoma

  • Choriocarcinoma

  • Gonadoblastoma

  • Mixed lesions

The general approach to Histology|histologic classification is the same as for the testis.






  • Germ Cell Ovarian Cancer
