Prenatal ultrasound detection of a congenital epulis in a triple X female fetus: a case report.

A case of congenital epulis in a triple X infant, whose intra-oral mass was first detected on a 33-week prenatal ultrasound, is described. Two previous ultrasound studies performed at 21 and 28 weeks' gestation showed normal facial anatomy, suggesting accelerated tumour growth during the third trimester. Genetic amniocentesis also showed the infant to possess a 47, XXX karyotype. Copyright 1999 John Wiley & Sons, Ltd.
