Case series of duodenal follicular lymphoma, observed by magnified endoscopy with narrow-band imaging.

摘要

Follicular lymphoma rarely occurs in the GI tract; it accounts for only 1% to 3% of all GI tract B-cell non-Hodgkin lymphomas. In the early stage, follicular lymphoma is often detected in the lymph nodes, and involvement of extranodal sites usually occurs as a result of disseminated nodal disease.2 The GI tract is one of the common sites of extranodal disease, and the duodenum is the most frequent site.3 Magnified endoscopy is clinically useful for detecting small cancer lesions of the GI tract and for differential diagnosis of benign and malignant lesions.4-5 However, there is little information about the magnified findings with narrow-band imaging (NBI) in duodenal follicular lymphoma. In this study, duodenal follicular lymphoma was observed by using magnified endoscopy with NBI.
