Neonatal Sacrococcygeal Mass: From Lipoma to Teratoma

ABSTRACT Sacrococcygeal masses in neonates that appear benign, such as presumed lipomas, may conceal germ cell tumors. Careful clinical evaluation, functional anorectal assessment, and magnetic resonance imaging are essential to differentiate benign lesions from sacrococcygeal teratomas and guide appropriate surgical management and follow‐up.
