A CASE OF MONOMORPHIC EPITHELIOTROPIC INTESTINAL T-CELL LYMPHOMA WITH LONG-TERM SURVIVAL AND CHALLENGING DIAGNOSIS OF RECURRENCE

Abstract

A 72-year-old man was referred to our clinical department with chronic diarrhea. The upper and lower gastrointestinal endoscopy results were normal. Middle gastrointestinal endoscopy revealed no significant findings, edema of the small intestinal mucosa, or villous atrophy. The pathological findings of the small intestinal mucosa did not lead to an accurate diagnosis. Here, the patient was diagnosed with monomorphic epitheliotoropic intestinal T-cell lymphoma by comparing past and present pathological findings; however, the symptoms and endoscopic findings are rare. Here, we report this case because long-term survival is rare and it is difficult to prove recurrence of the disease.
