Esophagogastroduodenoscopy images. Esophagogastroduodenoscopy performed 3 months after dupilumab treatment revealed gastric ulcers in the lesser curvature of the cardia (a) and posterior wall of the gastric body (b). Whitish mucosa was also noted in the lesser curvature of the gastric body (c).

Esophagogastroduodenoscopy revealed gastric ulcers in the lesser curvature of the cardia (Figure 1(a)) and in the posterior wall of the gastric body (Figure 1(b)). Whitish mucosa was also observed in the lesser curvature of the gastric body (Figure 1(c)).
Pathology images. Biopsy from the gastric ulcers showed the infiltration of eosinophils (a x 4; b x 40).

Biopsy of the gastric ulcers revealed more than 100 eosinophils per high-power field, which were infiltrating into the lamina propria and even the epithelium of the gastric mucosa (Figure 2); no neoplastic cells were noted.
Esophagogastroduodenoscopy images. Endoscopy performed 4 weeks after prednisone administration revealed the resolution of gastric ulcers. No eosinophils were identified in the biopsied specimens.
