title: [Intravascular lymphoma causing acute abdomen].
abstract: A 65-year old man presented with acute abdominal pain and fever. The initial diagnosis was small bowel gangrene. Pathology revealed small to large abdominal vessels obliterated by cells of intravascular B-cell-lymphoma (IVL). Visceral IVL involvement is common at autopsy but rarely reported in patients with acute abdomen. The subtype of diffuse large B-cell lymphoma is a rare and aggressive malignancy, which in typical cases is characterized by cephalic or cutaneous manifestation. Few cases showed involvement of large vessels which in combination to fibrin thrombi may lead to infarction of the organ involved. Thus IVL should be considered in cases of ischemic diseases with fever of unknown origin.
