da fuq??? wth teeth and hair??? Teratomas are made up of a variety of parenchymal cell types representing more than 1 germ layer and often all 3. Arising from totipotential cells, these tumors typically are midline or paraxial.[3] The most common location is sacrococcygeal (57%). Because they arise from totipotential cells, they are encountered commonly in the gonads (29%). By far, the most common gonadal location is the ovary, although they also occur somewhat less frequently in the testes. Cystic teratomas occasionally occur in sequestered midline embryonic cell rests and can be mediastinal (7%), retroperitoneal (4%), cervical (3%), and intracranial (3%).[4] Cells differentiate along various germ lines, essentially recapitulating any tissue of the body. Examples include hair, teeth, fat, skin, muscle, and endocrine tissue.
