Ectopic Pancreatic Tissue Presenting as an Umbilical Mass in a Newborn: A Case Report

Abstract

The case of an ectopic pancreatic mass at the umbilicus in an 8-day-old male neonate is reported, the youngest patient with this condition ever reported in an English-language journal. The patient was healthy except for a protruding mass with intermittent mucous discharge at the base of the umbilical stump. Surgical intervention was performed under the impression of the umbilical mass. Pathology diagnosed an ectopic pancreas with acute hemorrhage. To the best of our knowledge, only one case of ectopic pancreas presenting as an umbilical mass with intermittent mucous discharge has previously been reported.

Multimodality Imaging of Pancreatic and Biliary Congenital Anomalies

“…This ectopic tissue can be found in the stomach (26%-38% of cases), duodenum (28%-36%), jejunum (16%), Meckel diverticulum, or ileum. Rarely, it occurs in the colon, esophagus, gallbladder, bile ducts, liver, spleen, umbilicus, mesentery (Fig 13), mesocolon, or omentum (28,(33)(34)(35). The ectopic tissue usually measures 0.5-2.0 cm in its largest dimension (rarely up to 5 cm) and is located in the submucosa in approximately 50% of cases.…”

“…The ectopic tissue usually measures 0.5-2.0 cm in its largest dimension (rarely up to 5 cm) and is located in the submucosa in approximately 50% of cases. Ectopic pancreas in the gastrointestinal tract is usually asymptomatic, although complications such as stenosis, ulceration, bleeding, and intussusception may develop (28,34).…”

The umbilical mass: a rare neonatal anomaly

“…The differential diagnosis of an umbilical mass in the neonate includes persistent omphalomesenteric (vitelline) duct, urachal derivatives, as well as the rare findings of ectopic pancreatic [1,2] and liver tissue [3]. Our patient was unique in that, unlike several case reports of a ''giant umbilical cord'' in the literature, he had a normal umbilical cord with a significant amniotic remnant with irreducible contents [4,5].…”

Clinics in diagnostic imaging (158)

“…(2) Ectopic pancreatic tissue has also been reported in the liver, gallbladder, spleen, common bile duct, retroperitoneum, umbilicus, lymph nodes, and in extra-abdominal locations such as the lungs and mediastinum. (2)(3)(4)(5)(6)(7) By four to five weeks of gestation, the pancreas is formed by the ventral and dorsal buds of the endodermal lining of the duodenum. The dorsal bud grows more rapidly than the ventral bud.…”
