Travelers to Chagas disease endemic regions of Latin America may be at risk for Trypanosoma cruzi infection. We report a 67-year-old woman who screened positive for T. cruzi infection while donating blood.
NK cell enteropathy is a recently identified, slow-progressing condition characterized by abnormal NK cell activity in the gut that can mimic lymphoma.
A case study of a 69-year-old woman showed persistent abdominal pain and ulcerations due to atypical NK cell infiltrates, with no progression over 10 years.
It is crucial to recognize NK cell enteropathy to prevent misdiagnosing it as an aggressive form of cancer.
