In a 77-year-old Japanese housewife who was undergoing regular colonoscopy for follow-up of a colon polyp, a total colonoscopy showed an elevated lesion in the rectum. Histological findings of a conventional biopsy from the lesion showed a mucosa-associated lymphoid tissue (MALT) lymphoma, and the patient was diagnosed as having clinical stage 1 disease. We elected to administer antibiotic therapy as the serological test for anti-Helicobacter pylori antibody was positive and Helicobacter pylori was detected in a culture of the biopsy specimens. The antibiotic therapy was successful, however, colonoscopy after the eradication therapy showed a residual lesion. Histologic examination can’t deny the possibility of the presence of a residual MALT lympph.
