Oesophageal squamous papilloma in paediatric population: a single-centre case series.

Purpose: Oesophageal squamous papilloma (OSP) is a rare epithelial lesion with an unclear aetiology, found incidentally in upper gastrointestinal endoscopy (UGE). We evaluate the epidemiology, general features and endoscopic and histological characteristics of OSP in children in a single centre.

Methods: We conducted a retrospective search of 3568 medical records of children under 18 years old who underwent UGE between 2004 and 2022, at Hospital Metropolitano de Quito, Ecuador.
