Abstract

Background: Neonatal tumors are usually prenatally diagnosed or within the irst 30 days of life. The true incidence of
neonatal tumors is unknown as a great number of pregnancies with a prenatally diagnosed mass result in stillbirth or
miscarriage. Most solid neonatal tumors are benign whereas less than 50% of neonatal neoplasms are malignant;
however, some tumors with malignant patterns may histologically show benign behaviors. The incidence of malignant
tumors is 1 in every 12,500-27,500 live births, accounting for 2% of all childhood cancers. Teratomas are the most
common perinatal neoplasms, accounting for 25-33% of the cases. Around two-thirds of all sacrococcygeal teratomas
(SCTs) are reported in the neonatal period but with a small risk of malignancy.
Case report: Herein, we reported a case of SCT in a newborn leading to a complicated cesarean delivery.
Conclusion: In general, teratomas are embryonic typically benign tumors arising from germ cells. They usually consist
of various tissues originating from two or more embryonic layers. These tumors are believed to be the most common
neonatal germ cell tumors. The sacrococcygeal region is the most common site for extragonadal teratomas formation.
