Sacrococcygeal teratoma. Sacrococcygeal teratoma (SCT) is a type of tumor known as a teratoma that develops at the base of the coccyx (tailbone) and is thought to be derived from the primitive streak. Sacrococcygeal teratomas are benign 75% of the time, malignant 12% of the time, and the remainder are considered immature teratomas that share benign and malignant features.
The sacrum is the triangular bone at the base of the spine that joins the pelvic bones. The coccyx (tailbone) is the last bone of the sacrum that hangs down in a point like a small tail. Symptoms include swelling and some bleeding under the skin.
