| Teratomas belong to a class of tumors which result from abnormal development of [[pluripotent]] cells: [[germ cell]]s and [[embryo|embryonal cells]]. Teratomas of embryonal origin are [[congenital disorder|congenital]]; teratomas of germ cell origin may or may not be congenital (this is not known). | | Teratomas result from a complication in the body’s growth process, involving the way that body cells differentiate and specialize.Teratomas arise in body’s germ cells, which are produced very early in the development of the fetus.Some of these primitive germ cells become our sperm- and egg-producing cells. But germ cells can also be found elsewhere in the body, especially in the region of the tailbone and the mediastinum (a membrane separating the lungs). |
