A 34-year-old woman presented with 2 years of progressively worsening intermittent dysphagia, primarily to solids, especially meats, localized retrosternally. She reported no heartburn, nausea, vomiting, abdominal pain, weight loss, or changes in bowel habits. She reported no medications or comorbidities. Physical examination was unremarkable. Results of a recent complete blood cell count were normal. Despite taking ranitidine (150 mg twice daily), she continued to have bothersome daily dysphagia, prompting her primary care clinician to order esophagogastroduodenoscopy (EGD). The EGD showed vertical furrows and circumferential rings in the esophagus (Figure 1A), while the stomach and duodenum appeared normal. Four biopsies each were taken from the proximal and distal esophagus (Figure 1B).

Eosinophilic esophagitis (EoE)
C. Prescribe omeprazole (40 mg twice daily)
The key to the correct diagnosis is the esophageal mucosal biopsies demonstrating numerous intraepithelial eosinophils, in the setting of dysphagia symptoms and supportive endoscopic findings, and the absence of alternate etiologies for the eosinophilia.1 Other etiologies of esophageal eosinophilia, such as gastroesophageal reflux disease, eosinophilic gastroenteritis, hypereosinophilic syndrome, infections, drug hypersensitivity reaction, Crohn disease, or achalasia, should be carefully considered and excluded based on presenting history, physical examination findings, and diagnostic data.1 Once the diagnosis of EoE was made, the patient was prescribed twice-daily proton pump inhibitor (PPI) therapy, a well-tolerated first-line treatment option.
