N2 - ABSTACT Teratoma is the most common ovarian and extragonadal germ cell tumor. Sacrococcygeal teratema is the most common teratoma in infancy. It has an incidence of 1 in 25000 to 40000 live births. A rare case of huge sacrococcygeal teratoma is presented here. He was a newborn with a very largy mass in his sacrum who born by cesarean section. The mass had a cystic and vascular appearance. It`s size was 204060cm. The weight of the newborn was 9kg (including the mass). He had no other abnormal finding upon clinical examination. He was normal urination and defecation. Surgical resection of the tumor was performed in 4 th day after birth. The weigh of the mass was 6 kilogram. Diagnosis of mature teratoma was histologically confirmed. Benign teratoma usually cause only functional disorders such as intestinal or urinary obstraction. In this case, however, there was also no functional disorder despite huge mass of the tumor.
