Palpable rectally, when not externally visible, sacrococcygeal teratomas have been recognized since antiquity, but their histologic segregation from other sacrococcygeal masses lagged into the twentieth century. That these tumors are potentially malignant, and that the incidence of this complication increases with age during infancy, was realized early this century, but it is only in the last two decades that the importance of (1) early surgery, (2) excision of the coccyx, and (3) a combined abdominosacral approach for lesions with retroperitoneal extension has been realized.

There were 253 dermoid tumors of the ovary studied. Torsion of the pedicle with hemorrhagic infarction proved to be the most frequent complication; malignant change was the most lethal. Nine patients with malignant dermoid tumors, most of them with locally advanced disease, were treated with conservative surgery, radiation, and/or chemotherapy. The longest known survivor lived 3 years; most patients died within a year. It was concluded that a more aggressive surgical approach might salvage some patients with locally advanced malignant disease.
