Abstract
Introduction: ENKL (Extranodal Natural killer/T cell lymphoma) of the gastrointestinal tract can be indistinguishable from Inflammatory bowel disease or from an infectious etiology affecting the terminal ileum.
Case Report: We report a case of a 36-year-old Mexican male who presented with severe non-specific lower abdominal pain, fever and laboratory data suggestive of a systemic disease. The initial differential diagnosis was inflammatory bowel disease because of the non-specific finding of terminal ileum thickening seen on a computed tomography scan. As occurs in most patients with ENKL, the patient died rapidly in the setting of an aggressive lymphoma and the complication of intestinal perforation.
Conclusion: The differential diagnosis of localized inflammation of the distal ileum most commonly is seen in Crohn's disease but the differential diagnosis is very broad and includes aggressive lymphomas such as ENKL. This diagnosis should be considered in a clinical setting of a patient from Asia or Latin America with the appearance of unexplained small bowel localized inflammatory disease. Early recognition and treatment can be life-saving.

Keywords: Abdominal pain, Gastrointestinal lymphoma, Ileitis, Inflammatory bowel disease
