Gastric hamartoma of the pylorus in an infant.

Gastric hamartomata, alternatively called adenomyomata, are rare, benign lesions of the gastric wall. They can present with a wide spectrum of symptomatology. Pure pyloric adenomyomata are exceedingly rare. We are reporting a 13-day-old infant with a gastric hamartoma at the pylorus presenting with gastric outlet obstruction mimicking infantile hypertrophic pyloric stenosis.
