case_images: Biopsies were taken of the stomach mucosa and mid-esophageal mass (see Figure 1).
case_images: Esophageal squamous papilloma in Case 1. Lesion is diagnosed pathologically with hematoxylin and eosin stain demonstrating a fibrovascular core branching out from the lamina propria forming finger-like projections without invasion into the submucosa surrounded by marked neutrophil infiltration and covered by acanthotic squamous epithelium (H&E, x20).

A fibrovascular core branching out from the lamina propria forming finger-like projections (yellow arrow) without invasion into the submucosa surrounded by marked neutrophil infiltration (red arrow) and covered by acanthotic squamous epithelium (black arrowhead) can be seen (H&E, x100).

case_images: Esophageal biopsy demonstrated findings consistent with squamous papilloma (see Figures 5 and 6).
case_images: Esophageal squamous papilloma in Case 3. Several fibrovascular cores branching out from the lamina propria with finger-like projections can be seen without invasion into the submucosa. These are surrounded by marked neutrophil infiltration and covered by acanthotic squamous epithelium (H&E, x100).
