Sacrococcygeal teratomas, tumours formed from different types of tissue, that can form, are thought to be related to primitive streak remnants, which ordinarily disappear.

Together with the posterior, and intercornual sacrococcygeal ligaments, they stabilize the sacrococcygeal symphysis, i . e . the joint between the sacrum and the coccyx.

18.
Add to that number sacrococcygeal teratomas diagnosed later in life, and teratomas in other locales, and the incidence approaches ten thousand new diagnoses of teratoma per year.
