 A 67-year-old man was admitted because of refractory diarrhea. Colonoscopy showed diffuse edematous and granular mucosa with reddish spots in all sites of the large intestine. While a diagnosis of inflammatory diseases such as infectious colitis was endoscopically suggested, the histologic examination of biopsy specimens revealed T-cell lymphoma. By extensive procedures including double-balloon endoscopy for the whole gastrointestinal tract, similar edematous and granular mucosa with or without erythematous areas was found in the stomach, duodenum, jejunum and the ileum. Southern blot analysis revealed a monoclonal integration of HTLV-1(human T lymphotropic virus type 1)provirus DNA in the tumor cells obtained from the jejunal specimens. Based on these findings, the diagnosis of ATLL(adult T leukemia/lymphoma)was established. Our case suggests that ATLL should be one of the differential diagnoses for patients with apparently inflammatory lesions in an extensive area within the gastrointestinal tract.
