A Rare Case of Prenatal Diagnosis and Management of Fetal Oral Cystic Mass

Abstract

Congenital fetal oral mass is a very rare entity. A correct ultrasound-based approach on the anatomic location, consistency, and vascularity will help us to narrow down the differentials antenatally but a confirmed diagnosis can be made by histopathological examination postnatally. We describe a case of a fetal oral cyst diagnosed antenatally at 20 weeks of gestation. On follow-up, fetal growth and amniotic fluid volume were normal with no changes in the size or the position of the cyst. The cyst was excised on the first neonatal day. Histopathology was consistent with a mucocele.
