“…Therefore, this may lead to misdiagnosing the condition as a malignant tumor. Due to this reason, an MRI was done for the present case to differentiate if the tumor was malignant or not 12 . The histological classification of SCT is divided into three types: malignant teratomas (consisting of malignant germ cells); immature teratomas (incompletely differentiated structures with a high risk of malignancy or embryonal components); and mature teratomas (fully differentiated tissues like hair, bone, and teeth).…”

Introduction and importance: A sacrococcygeal teratoma (SCT) is a rare embryonal tumor that emerges in the sacrococcygeal area. It affects one in every 35 000–40 000 live births. Herein, we report a case of a substantial SCT in a neonate. Case presentation: A neonate girl from consanguineous parents was delivered by cesarean section with a large mass (18×17 cm) in the sacrococcygeal area. The baby’s birth weight was 5 kg, of which 2.5 belonged to the mass. The vital signs were within normal ranges and she had weak movement with bluish peripheral limbs. Oxygen saturation was around 85% for a short period after birth. According to the American Academy of Pediatric Surgical Section, the tumor was type I. After the fifth day of delivery, a complete resection was done through a chevron incision. The patient was put on ‘nil by mouth’ for about 24 h and given intravenous fluid. Clinical discussion: The histopathological examination of the surgical specimen confirmed extragonadal immature teratoma. The histological classification of SCT is divided into three types: malignant teratomas (consisting of malignant germ cells); immature teratomas (incompletely differentiated structures with a high risk of malignancy or embryonal components); and mature teratomas (fully differentiated tissues). Conclusion: SCT has rarely been reported as a giant mass. Radiologic examinations in the early stages of pregnancy may be essential to the early diagnosis of the condition.

Background: This study aims to evaluate the outcomes of fetal sacrococcygeal teratoma (SCT) submitted to prenatal interventions. Methods: We performed a systematic literature review of fetal SCT patients and compared the outcomes between open fetal surgery and percutaneous intervention. In addition, we also compared the results of SCT fetuses who did not undergo any surgical intervention (NI). Results: We identified 16 cases of open fetal surgery (OS), 48 cases of percutaneous fetal intervention (PI), and 93 NI patients. The survival rate was 56.2% in OS, 45.8% in PI (p = 0.568), and 71.0% in NI patients. The gestational age at delivery was earlier in cases where there was no survival compared to cases where the fetuses did survive across all evaluated cohorts (OS: p = 0.033, PI: p < 0.001, NI: p < 0.001). The gestational weeks at delivery in OS and PI fetuses were more similar; however, OS tended to be performed later on in pregnancy, and the affected fetuses had more severe presented findings. In our evaluation, we determined that the presence of fetal hydrops and cardiac failure had no significant impact on survival in SCT cases. In NI patients, polyhydramnios was much higher in fetuses who did not survive compared to their surviving cohorts (p < 0.001). Conclusions: In conclusion, gestational age at delivery can affect the short-term prognosis of fetuses affected with sacrococcygeal teratomas. Regardless of the mode of delivery or the necessity for intervention during the fetal period, monitoring for complications, including polyhydramnios, can prevent premature delivery.
