A 52-year-old woman underwent health checkup, which revealed a multilocular cystic tumor (7 cm) in the presacral pelvic cavity. The mass was diagnosed as a sacrococcygeal cystic tumor with malignant potential, and we performed surgical resection via an abdomino-sacral approach, followed by laparoscopic surgery. Histopathological examination of the resected specimen revealed a mature sacrococcygeal teratoma. The patient's postoperative course was uneventful, and no recurrence was observed at 1 year and 5 months follow-up. Although rare in adults, mature sacrococcygeal teratomas are known to show malignant changes ; therefore, early surgical resection is recommended. A combined sacral and laparoscopic approach was useful for optimal visualization of the surgical field and procedural safety in our patient.
