title: Plasmablastic lymphoma of the lung: report of a unique case and review of the literature.
abstract: Non-Hodgkin lymphomas associated with acquired immunodeficiency syndrome are heterogeneous. Recently, a novel subtype of non-Hodgkin lymphoma occurring mostly in patients with acquired immunodeficiency syndrome has been described and designated as plasmablastic lymphoma. The histomorphologic and immunophenotypic findings of this distinct subtype of non-Hodgkin lymphoma have been characterized previously. Most patients present with oral cavity involvement. We report a case of plasmablastic lymphoma presenting as a lung tumor. To our knowledge, this is the first case report of this unusual subtype of diffuse large B-cell lymphoma in this location.
