Upper gastrointestinal bleeding caused by direct invasion of diffuse large B-cell lymphoma into the stomach in a patient with HIV infection: A case report

We present a rare case of direct invasion of DLBCL to the stomach wall that presented as upper GI bleeding in a patient with HIV. Diagnosis: Upper 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. Intervention: The patient was treated with 6 courses of rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). Outcomes: The patient achieved a complete response with 6 courses of R-CHOP treatment. No recurrence was observed during the 4-month follow-up period. Lessons: Because 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.
