RESUMO
PURPOSE: Intravascular large B cell lymphoma (IVLBCL) is a rare and aggressive variant of non-Hodgkin's lymphoma, characterized by multifocal proliferation of lymphoma cells exclusively within small and medium blood vessels. IVLBCL can be systemic and quite polymorphic, which often makes it difficult to diagnose, thus delaying appropriate treatment. PATIENTS AND METHODS: We report three patients of atypical IVLBCL, through the study of which we overview recent knowledge about IVLBCL. RESULTS: The first patient initially presented with peripheral thrombocytopenia and splenic destruction of platelets, later completed with an interstitial pulmonary syndrome. The second patient, of African origin, we believe is the first case of a black patient with IVLBCL described in the medical literature. The third belongs to the rare group of occidental patients that present an IVLBCL associated with a hemophagocytic syndrome. CONCLUSION: Intravascular large B cell lymphoma is a systemic and polymorphic disease. Awareness of this entitiy should allow rapid and appropriate management.
