Previously Unreported Esophageal Lymphoid Polyp in a Child: A Case Report with Histopathology.

Introduction: Benign esophageal tumors are uncommon; most are detected by chance upon endoscopy. Lymphoid polyps, like those of the small and large intestine, have not been reported to occur in the esophagus. We describe an esophageal benign lymphoid polyp. Case Report: A 7.5-year-old girl was referred with dysphagia. Upper endoscopy demonstrated and removed a single small pedunculated polyp in the upper third of the esophagus. The polyp consisted of two hyperplastic lymphoid aggregates in the lamina propria covered by stratified non-keratinizing squamous epithelium. Discussion: Esophageal polyps may be produced by hyperplastic lymphoid tissue and may be a cause of dysphagia.
