ABSTRACT
Sacrococcygeal teratomas were first described by Virchow in 1869 and, because of their complexity, 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 35000-40000 live births, and a female preponderance of 3:1.
