The patient was started on intravenous (IV) ondansetron, pantoprazole, ketorolac (as needed), maintenance IV fluids, and a
clear liquid diet. At sixty hours after ingestion, an esophagogastroduodenoscopy (EGD) was performed which revealed blistering and edema of the soft palate (Figure 1) and epiglottis (Figure 2), diffuse and circumferential erythema of the entire esophagus with an exudate likely to be desquamated mucosa (Figures 3(a) and 3(b)), and linear erythema of the body and fundus of the stomach (Figure 4).
