1 INTRODUCTION Intravascular large B-cell lymphoma (IVLBCL) is a rare subtype of extranodal diffuse large B-cell lymphoma (DLBCL), named for the loose distribution of lymphoma cells within small to medium-sized blood vessels.1 Unlike solid tumours, IVLBCL usually does not form a solid mass.2, 3 Also due to the near-ubiquitous presence of the lymphoma cells, the clinical symptoms are highly heterogeneous. IVLBCL cells have strong and constant CD20 expression.
