AbstractWe retrospectively studied all thirty-five children (M 6, F 29) with sacrococcygeal
teratomas admitted to Siriraj Hospital between 1974 and 1999. Although an abdominal delivery
is recommended for lesions greater than 5 em to avoid dystocia, the average diameter of
masses which required interventions from dystocia (n = 3) was not different from vaginal
delivery (n = 27). All except two first presented with sacral masses recognized at birth. One
patient presented with an abdominal mass and the last one was diagnosed after suffering from
difficulty in urination. Ninety-seven per cent of cases were completely excised initially (32
sacral, 2 abdomino-sacral approaches), however, six patients required other treatment for
recurrent diseases. One mature teratoma recurrence was resected. Two patients who had
malignant recurrences following complete benign excisions, died from advanced malignancy.
Four presented with malignancy initially. Wound infection, bladder atony and UTI were the
most common complications postoperatively. Advanced malignancy was the major cause of
death. No patient died directly from the procedure.
