Two Cases of Intravascular Lymphomatosis

Intravascular lymphomatosis is a rare lymphoma characterized by neoplastic proliferation of malignant cells within the lumen of small blood vessels, usually presenting in the central nervous system or on the skin. Intravascular lymphomatosis is manifested clinically by fever, dementia, cutaneous nodules or plaques, and occasionally, dyspnea. The diagnosis of intravascular lymphomatosis is difficult because of misleading clinical features mimiking vasculitis, infection, stroke, or other neoplasm. We report two cases of intravascular lymphomatosis pesented as fever and skin rash. Those are confirmed by involved tissue biopsy. All cases were treated by combination chemotherapy, but the response was not good. Infectious problems were complicated and disease were progressed. (Korean J Hematol 2002;37:138142)
