Inravascular lymphoma is a fairly new entity that is only recently described. It is is a rare form of diffuse LBCL characterized by preferential intravascular growth of malignant lymphocytes, aggressive behavior, and an often fatal course. IVLBCL usually affects elderly patients with poor performance status, elevated lactic dehydrogenase serum levels, anemia, and B symptoms. There is no standard therapy and most information about therapy comes from case reports. CHOP, adriamycin and other regimens have been tried. There is a report of excessive toxicity from rituxan. There is no credible medical evidence supporting an autologous transplant after a compete response.
