ABSTRACT
Sacrococcygeal teratomas (SCT) were first described by Virchow in 1869 and were called ‘teratomas’ from the Greek teratos onkoma, meaning ‘monstrous tumor’. They represent the most common germ-cell tumors of childhood (40 percent), with an incidence of approximately 1 in 35 000-40 000 live births, and a female preponderance of 4:1.
