SUCCESSFULLY COMPLETE EXCISION OF A HUGE SACROCOCCYGEAL TERATOMA: A CASE REPORT

Abstract

A female infant was born with a huge sacrococcygeal teratoma (SCT) at 36 weeks of gestation with a weight of 4546g (combined weight of the infant and tumor). The patient's mother developed polyhydramnios and cesarean section was performed at 36 weeks of gestation. MRI showed Altman classification type Ⅱ SCT. We performed abdominoperineal resection at 3 days after birth. The mass was completely excised, and the size and the weight of the mass were 18×12×15cm and 1100g (Weight of SCT against body weight; 393 g/kg), respectively. The pathological findings revealed a grade Ⅱ immature teratoma with no malignant elements such as yolk sac tumor. The patient was discharged at 45 days after birth with fecal continence, but neurogenic bladder dysfunction. At 9 months after surgery, the patient was doing well with no evidence of tumor recurrence, and AFP levels had returned to normal values.
