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.
Coccydynia is a medical term meaning pain in the coccyx or tailbone area, usually brought on by sitting too abruptly.occydynia may also be caused by sitting improperly thereby straining the coccyx. Rarely, coccydynia is due to the undiagnosed presence of a sacrococcygeal teratoma or other tumor in the vicinity of the coccyx. In these cases, appropriate treatment usually involves surgery and/or chemotherapy.
