Usefulness of magnifying endoscopy and endoscopic ultrasonography for the gastric involvement of follicular lymphoma
A 61-year-old man received an esophagogastroduodenoscopy for further investigation of mesenteric lymphadenopathy. Esophagogastroduodenoscopy revealed swollen gastric folds and cobble stone mucosa in the gastric body. Magnifying endoscopy with narrow-band imaging showed branched abnormal vessels and the absence or destruction of gastric pits. Endoscopic ultrasonography (EUS) depicted homogeneously hypoechoic thickening of the submucosal layer where the mucosal changes were observed. The patient was diagnosed with follicular lymphoma by biopsy of these lesions. We should recognize that these endoscopic features are consistent with follicular lymphoma involving the stomach and that concurrent EUS is useful for diagnosis and identification of adequate biopsy sites.
