Intravascular large B-cell lymphoma in Hispanics: a case series and literature review.

Intravascular large B-cell Lymphoma (IVLBCL) is a rare subtype of extra nodal non-Hodgkin's lymphoma, which is challenging to diagnose and has a poor prognosis. Here we describe three non-White Hispanic patients newly diagnosed with IVLBCL within 14-month period. All of them presented with persistent fever of unknown origin and symptomatic severe anemia as the initial manifestations. Two out of three cases were successfully diagnosed in a timely manner by fat pad biopsy and have remained disease free up to 34 months after chemotherapy. The third case was diagnosed by bone marrow biopsy and deceased one week later after choosing home hospice care. To date, this is the largest published case series of IVLBCL in non-White Hispanics.
