Eosinophilic gastroenteritis (EGE) is an uncommon disease in both immunocompetent and immunocompromised. We describe a 57-year-old male with human immunodeficiency virus who presented to us with chronic diarrhea. He had no history of allergies and had significant weight loss, normal systemic examination, and a complete blood count showing no eosinophilia. After an esophagogastroduodenoscopy, the diagnosis of EGE was made by histopathological findings. The symptoms started improving with the initiation of treatment with oral prednisolone.
