A rare cause of gastric outlet obstruction in the newborn: Pyloric ectopic pancreas.

This report describes a case of symptomatic pyloric ectopic pancreas simulating infantile hypertrophic pyloric stenosis (IHPS) in an 1-month-old boy. There are few cases reported in the English-language literature with the same clinical presentation during the neonatal period. Rarely is the entity symptomatic, and it should be kept in mind in differential diagnosis of nonbilious vomiting, especially in neonates. The ectopic pancreas should be removed because of the late complications when found incidentally.
