  • Germ cells are the cells that develop in the embryo and become they make up the reproductive system in males and females.
  • After the development of germ cells, they follow the body midline path and descend into the pelvis as ovarian cells or into the scrotal sac as testicular cells.
  • Th ovaries and testes are called gonads and many ovarian and testicular tumors have germ cell origin.
  • The pathophysiology of germ cell tumors is different based on the classification of germ cell tumors
  • Each of the distinct entities of germ cell tumor has a different pathogenesis
  • Germ cell tumors are classified as;
    • Gonadal
      • seminoma
      • Dysgerminoma
      • Germinoma
    • Extragonadal
      • Embryonic
        • Mature/Immature teratoma
      • Extraembryonic
        • Chorio carcinoma/Yolk sac tumor
