Abstract

A 60-year-old Japanese man was diagnosed with systemic follicular lymphoma with duodenal, jejunal, and ileal involvement. The duodenal lesion showed typical endoscopic features with multiple whitish granules. Chemotherapy with bendamustine and rituximab was administered, and complete remission was confirmed by CT scanning and positron emission tomography scanning. Although the duodenal granular lesions did not completely disappear, magnifying observation for the remaining lesions showed no evidence of residual lymphoma. Complete remission was pathologically confirmed by biopsy examinations. This case suggests the usefulness of magnifying observation in evaluating the effects of treatment for duodenal follicular lymphoma lesions.
