 A 60-year-old male was admitted to our hospital complaining of tarry stool. A jejunal stenosis with a circumferential ulcer was pointed out by double-balloon endoscopy(DBE), but definitive diagnosis was not obtained. Follow-up DBE with biopsy performed one year later resulted in a diagnosis of follicular lymphoma. The patient underwent chemotherapy with a regimen of cyclophosphamide, doxorubicin, vincristine, and predonisolone combined with rituximab(R-CHOP). Complete regression of the tumor was achieved, and recurrence of follicular lymphoma is not recognized 3years after the chemotherapy. Thanks to the advance of DBE, we can make both histological diagnosis of malignant lymphoma in the small intestine and clinical staging without resorting to surgery. Our case indicates that this type of follicular lymphoma can occur in this location and present with the features of a stenotic lesion.
