Primary diffuse large B-cell lymphoma at gastrojejunostomy site: A rare case report

Abstract

The occurrence of lymphoma at the gastrojejunostomy (GJ) site is infrequent. Only two GJ site lymphoma cases are reported in the literature. Endoscopy and biopsy are primary methods for diagnosis which should be performed in these patients for the exact diagnosis. Here, we report a case where an elderly patient who developed a non-Hodgkin lymphoma of the GJ site had undergone GJ for benign peptic ulcer disease 5 years ago. Upper gastrointestinal scopy showed polypoidal growth at the GJ site with pyloric stenosis. Diagnosis of poorly differentiated adenocarcinoma was made on a biopsy sent from the GJ site. On laparotomy, there were omental deposits. Biopsy of omental deposits was reported as diffuse large B-cell lymphoma (DLBCL). Both biopsies were sent for immunohistochemistry which showed DLBCL. Palliative GJ was performed; the patient was asked for a follow-up for chemotherapy. After 10 days, he developed septic shock and succumbed.
