 A 70s man was examined by EGD(esophagogastroduodenoscopy)as a follow-up after gastrectomy. EGD determined a cluster of white nodules in the descending part of the duodenum. Chromoendoscopy with indigo carmine depicted heterogeneity in the size of the white nodules. Magnifying endoscopy with narrow band imaging displayed swollen villi, within which opaque whitish spots and dilated vasculature were detected. Biopsy specimens from the white nodules comprised follicular-like structures of small-sized atypical lymphocytes in the subepithelial stroma, which were diagnosed as follicular lymphoma by immunohistochemistry. Various diseases which manifest whitish villi should be considered for the diagnosis of white nodules in the descending part of the duodenum. Follicular lymphoma is a representative condition among those diseases.
