A report is presented of a 48-year-old gay man, HIV-positive for 7 years, who came to the emergency room due to six hours of abdominal pain accompanied by anorexia, nausea, and dry heaves. Initial examination and laboratory tests showed nonspecific bowel gas, and the patient was discharged with instructions to use an enema at home for constipation. After worsening of symptoms, a private physician diagnosed acute abdomen with surgical consultation. A jejunal perforation secondary to B-cell Hodgkin's lymphoma was diagnosed and the patient was treated with low-dose CHOP (cytoxan, adriamycin, vincristine, and prednisone) for four cycles and had his antiretroviral regimen changed.

A 79-year-old man with a 2-month history of fever and weight loss was admitted to our hospital because of an acute abdomen. Abdominal CT scans showed marked sectional thickening and edema of the small intestine. On laparotomy, a 16-cm section of the small intestine was ischemic and necrotic; therefore, segmentectomy of the intestine was performed. A thrombus was noted at the stump of the mesenteric artery branch. Histopathological analysis of the resected intestine revealed fibrin thrombi in both mesenteric arteries and veins. Furthermore, a cluster of large, abnormal lymphoid cells bordering the intima of most branches of the mesenteric veins and small vessels was observed. Immunohistochemical analysis revealed that these abnormal cells were positive for CD20, leading to a diagnosis of intravascular large B-cell lymphoma (IVLBCL). The patient was successfully treated with standard R-CHOP chemotherapy; however, the lymphoma recurred in the central nervous system 18 months after the initial diagnosis, and the patient died. Simultaneous thrombosis of the mesenteric artery and vein is unusual as a clinical manifestation of IVLBCL. However, IVLBCL should be taken into consideration when ischemic disorders of unknown cause, accompanied by fever of unknown origin, are encountered.
