The plasmablastic lymphomas (PBLs) are a group of aggressive B cell neoplasms that share pathobiological features with large B cell lymphoma (LBCL) and plasma cell myeloma. They are characterized by a diffuse proliferation of large immunoblastic cells with an immunophenotype resembling plasma cells (Colomo et al, 2004; Swerdlow et al, 2016). First described in the oral cavity of human immunodeficiency virus (HIV)-positive patients, PBL is now recognized to occur in other anatomic sites and in other immunosuppressed states, including among the elderly (Hsi et al, 2011).
