ABSTRACT
A sacrococcygeal teratoma (SCT) is a neoplasm arising from the caudal end of the spine, usually protruding from the inferior end of the infant's spinal column and displacing the anus forward. These tumors have a female-to-male ratio of at least 3:1. A teratoma is a true tumour or neoplasm composed of multiple tissues of kinds foreign to the part in which it arises. The risk of malignancy depends on three factors: the site and the extent of the tumor and the age at diagnosis. Before routine antenatal ultrasound examinations became widely accepted, the most common presentation was as a large sacral mass that is immediately obvious at birth. Most cases presenting as neonates to pediatric surgeons will have a large skin-covered mass protruding from the coccygeal region, pushing the anus and vagina anteriorly. Infants presenting with malignant tumors usually present with a rapidly growing buttock mass.
