Esophageal polyps are uncommon findings in pediatric patients, and reports have been limited to case reports. Esophageal polyps have been previously ascribed to esophagitis secondary to gastroesophageal reflux, medications, infections and recurrent vomiting. They have been associated with underlying conditions such as hiatal hernia, Barrett's esophagus, eosinophilic esophagitis and Crohn's disease. Presenting complaints of children with esophageal polyps have included vomiting, dysphagia, hematemesis and abdominal pain. The aim of this paper is to characterize the incidence, clinical presentation and progression, histologic subtypes and associated mucosal abnormalities in children with esophageal polyps. A retrospective multicenter study was performed at four institutions identifying diagnosis of esophageal polyps in pediatric patients (<21 years). Information was obtained from patient charts, endoscopy reports and histopathology reports. Specimens and slides were examined by experienced pediatric pathologists for all included cases. Esophageal polyps were identified in 13 patients (9M) from 9438 esophagogastroduodenoscopies (0.14%). Mean age of subjects was 9.2 years. Vomiting was the most common indication for endoscopy. Polyp location was at the gastroesophageal junction in 7 of the 13 cases. Most polyps were inflammatory (n = 7). Esophagitis was noted in 69% of those with esophageal polyps. Repeat endoscopies in six patients at a mean interval of 8 months noted persistence of polyps in all six patients. This paper is the first to characterize esophageal polyps in pediatrics. These polyps are rare in children and often are associated with esophagitis. Presenting complaints seem to vary by age. Polyps did not consistently change with either time or acid suppression. The optimal management strategy has yet to be defined and likely depends on the underlying pathophysiologic process.
