Development of Esophageal Epidermoid Metaplasia in a Pediatric Patient After Stevens-Johnson Syndrome.

Abstract

Esophageal epidermoid metaplasia (EEM) is a rare condition that has not been described in Stevens-Johnson syndrome (SJS) and has only been described once in pediatrics. Neither the relationship, treatment, nor surveillance between SJS, esophageal strictures, and EEM has been established. We report the first case of EEM in an 8-year-old girl with esophageal stricture after SJS. Pediatric patients presenting with dysphagia after SJS should be evaluated for esophageal stricture and subsequent EEM development. Owing to EEM's, association with esophageal squamous cell cancer, close follow-up, biopsy surveillance for dysplasia, endoscopic treatment, and TP53 genetic sequencing should be considered.
