{Abstract}: Primary gastrointestinal non-Hodgkin lymphoma, while rare, most often presents as diffuse large B-cell lymphoma located in the stomach or ileocecal region. Presenting symptoms include abdominal pain, gastrointestinal bleeding, weight loss, or obstructive symptoms. Imaging can reveal ileitis or obstruction. We report a case of a man from Honduras with latent tuberculosis and chronic hepatitis B who presented with features of Crohn's disease through clinical, radiologic, and endoscopic findings but was ultimately diagnosed with diffuse large B-cell lymphoma by histology. We emphasize the importance of maintaining a broad differential for ileitis and the importance of histologic sampling when evaluating ileitis.
