Teratomas are a type of gonadal tumour occurring both in the ovaries and the testes. Derived from multipotent cells, they contain tissue from all three germ layers and exhibit a wide range of differentiation.
Types:
Note that about 40% of teratomas occur mixed with seminomas.
The vast majority secrete human chorionic gonadotropin and/or alpha-feto protein which can be measured in the serum and used as a tumour marker. They are less radiosensitive than seminomas.
