Abstract

We describe a patient who presented with large cardiac diffuse large B-cell lymphoma (DLBCL) and adrenal masses. The patient also had subcutaneous intravascular lymphoma lesions which were detected by random skin biopsy. Although ambiguous, minimal extravascular location of lymphoma cells is permitted for the diagnosis of intravascular large B-cell lymphoma (IVLBCL) in the WHO definition, a number of rare cases have been reported as having concomitant tumours in other organs, such as the adrenal gland, brain, and penis. We assume that IVLBCL might be a peculiar feature of DLBCL characterised by preferential localisation of lymphoma cells within the capillaries rather than a distinct disease entity of DLBCL.
