A 13-year-old previously healthy female presented to her pediatrician with progressive dizziness, pallor, exercise intolerance, fatigue, and pica. Nine months later, she was diagnosed with microcytic anemia. As part of the workup, she underwent a stool hemoccult test, which was positive, necessitating an esophagogastroduodenoscopy (EGD) and colonoscopy to explore the etiology of the anemia. EGD and colonoscopy were grossly unremarkable. Gastric, small-bowel, and colon biopsies revealed slightly increased eosinophils in the gastric mucosa. Fourteen months later, repeat EGD demonstrated nodularity in the gastric body. A photomicrograph of the gastric body is shown.
