Overview

Objective: Description of newborn with early prenatal diagnosis of sacrococcygeal teratomia.

Desing: Case report.

Setting: Department of Obstetrics and Gynecology, 2nd Faculty of Medicine and Faculty Hospital Motol Prague.

Case report: In this case report a term neonate with a massive sacrococcygeal teratoma was delivered by a cesarean section (approach by Geppert) with an intrapartal relieving punction of the tumor. It was a type II SCT with both pelvic end extracorporal component with a size of 60×35 centimeters. The tumor was completely resected during the first day of life and was followed by a normal function of lower extremities, normal bowel function and only transitional urinary tract symptoms.

Conclusion: A sacrococcygeal teratoma (SCT) is the most common congenital tumor in newborns with reported incidence of 1 : 35000-40000 live births affecting more frequently females (4 : 1). This germinal tumor is either benign (mature) or malignant (immature), mature types are more common in neonates. A SCT is usually diagnosed by prenatal ultrasound, magnetic resonance is performed to characterize it‘s size and content, type of tumor (type I–IV Altman classification) and relation to surrounding tissues. Preemptive early delivery by cesarean section is recommended when the tumor exceeds the diameter of 5 centimeters to avoid complications during vaginal delivery (rupture, bleeding etc.). The primary treatment of SCT is an early surgical resection with a complete resection of the coccyx („en bloc“ resection), malignant tumors are indicated for adjuvant chemotherapy. Long term complications can be urinary tract or bowel dysfunctions, lower extremity muscle weakness or paralysis and recurrence of the tumor with potential malignancy.
