Visceral yolk sac-derived tumors

The International Journal of Developmental Biology, 1993
Externalization of the visceral yolk sac, after fetectomy, induces the development of extra-embryonal fetal tumors in rodents. These tumors are either benign teratomas that appear 3 to 4 weeks after the displacement of the yolk sac or malignant tumors, i.e. yolk sac carcinomas. The latter appear 4 to 8 months after the surgery.
