RationaleDiffuse large B-cell lymphoma (DLBCL) is the most frequent human immunodeficiency virus (HIV)-related Non-Hodgkin's Lymphoma of the stomach. Although gastrointestinal (GI) bleeding due to primary gastric lymphoma has been previously reported in the literature, there have been no reports of stomach wall involvement of intra-abdominal lymphoma presenting as GI bleeding.Patient ConcernsWe present a rare case of direct invasion of DLBCL to the stomach wall that presented as upper GI bleeding in a patient with HIV.DiagnosisUpper endoscopy showed a large ulcerofungating mass in the lesser curvature of upper stomach body. The computed tomography scan showed an about 22 × 12 cm sized huge mass that invades into the stomach wall in the abdominal cavity. A diagnosis of DLBCL was established after histological examination.InterventionThe patient was treated with 6 courses of rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP).OutcomesThe patient achieved a complete response with 6 courses of R-CHOP treatment. No recurrence was observed during the 4-month follow-up period.LessonsBecause of the high incidence of lymphoma in patients with HIV, if such patients complain of dyspepsia, epigastric soreness, or melena, malignant tumors, such as lymphomas or stomach cancers, should be suspected. As in this patient, doctors should be aware that intra-abdominal lymphoma can invade into the stomach wall and cause bleeding.
