title: Plasmablastic lymphoma of gingiva mimicking a reactive lesion: a case report.
abstract: Oral plasmablastic lymphoma (PBL) is a rare malignancy, associated with HIV or other immunocompromised conditions. The lesion constituted a new subtype of diffuse large B-cell lymphoma and proposed a distinct entity based on its basic morphology, its clinical behaviour involving predominantly extramedullary sites (particularly oral cavity), and its limited antigenic phenotype data suggesting plasmacytic differentiation. Authors here report a case of apparently healthy individual aged 35 years, presenting one-month history of swelling associated with loosened teeth around upper anteriors. Following incisional biopsy, routine histopathologic and immunohistochemical studies, the diagnosis of plasmablastic lymphoma was given.
