Abstract

Objectives: Esophageal squamous papilloma (ESP) is a rare epithelial lesion most commonly seen in adults, with an unclear etiology and limited pediatric data available. The aim of this study was to provide an estimated prevalence of this lesion in our pediatric population, as well as to identify any demographic, clinical, or pathologic associations-including human papilloma virus (HPV) infection, which has been linked with ESP in adult literature.

Methods: ESP cases at University Hospitals Rainbow Babies & Children's Hospital were identified by conducting a retrospective search through all esophagogastroduodenoscopies (EGDs) performed in children under 18 years old, from January 1, 2000 to December 31, 2014. Histopathology reports were analyzed including Fluorescence In Situ Hybridization (FISH) for HPV, and a comprehensive chart review was performed for demographic data.

Results: Of 12,459 children who required an EGD, 10 children were identified with ESP on biopsy, with ages ranging from 2 to 17 years. This provides an estimated prevalence of 0.08% over the entire study period. Seventy percentage of patients underwent endoscopy for abdominal pain, and 40% presented with gastroesophageal reflux. Sixty percentage of lesions were in the proximal esophagus, and 80% of patients had isolated lesions. Notably, none of the lesions tested were positive for HPV on FISH analysis.

Conclusions: ESP is a rare benign lesion found incidentally in the pediatric population. The prevalence at our institution was 0.08%. All samples tested for HPV via FISH analysis were negative. As a result, regular analysis for HPV may not be necessary in pediatric patients with ESP in the future.
