Esophagogastroscopy was performed and revealed diffuse pseudomembranes in the lower one-third of the esophagus (Figure 1).
Pathologic findings of the lower esophagus revealed squamous cell hyperplasia (a), mild acute and chronic inflammatory infiltrations (b), a few small foci of splitting of the squamous epithelium (c), and a few intraepithelial cystic degenerations (d).

The pathologic findings exhibited foci of splitting of the squamous epithelium with few intraepithelial cystic degenerations, no parakeratosis, no basal cell hyperplasia, mild acute and chronic inflammatory infiltrates with focal squamous cell hyperplasia, and normal underlying mucosa, which were similar to the previous findings (Figure 2).
