Epidermoid Metaplasia of the Esophagus

A 76-year-old man presented with a 1.5-year history of intermittent globus sensation and rare episodes of solid food dysphagia. He reported no heartburn or regurgitation. Two months previously, he had undergone esophagoduodenoscopy that revealed Los Angeles classification grade C esophagitis with a nonobstructing peptic stricture. Treatment with pantoprazole, 40 mg twice daily, was initiated. Repeated esophagoduodenoscopy at the current presentation revealed healing of the prior erosive esophagitis and well-demarcated, white plaques with altered texture in the distal esophagus (Figure  1).
