A 71-year-old man presented to our hospital due to diarrhea and weight loss that had persisted for about 2 months. The upper and lower gastrointestinal endoscopy revealed various lesions with different morphologies in the esophagus, stomach, duodenum, ileum, and colon. Biopsies from each lesion resulted in the diagnosis of a monomorphic epitheliotropic intestinal T-cell lymphoma. There is no report of total gastrointestinal involvement in this disease, and we consider this case to be valuable.
