title: The umbilical mass: a rare neonatal anomaly.
abstract: Umbilical anomalies are a rare presentation in the pediatric patient. The differential diagnosis includes anomalies resulting from urachal and vitelline duct derivatives such as urachal sinus, urachal cyst, urachal diverticulum, patent urachus, herniated Meckel's diverticulum, umbilico-enteric fistula, or umbilical polyp. In this article, a case presentation of an umbilical anomaly along with the differential diagnosis and management options are discussed. Based upon this review of the literature, the authors propose a management algorithm for treating children with umbilical anomalies.
