Abstract
Diffuse large B-cell lymphomas (DLBCLs) are defined as neoplasms of large transformed B cells, i.e. with nuclear diameter more than twice that of a normal lymphocyte. These account for 30-40% of all adult non-Hodgkin's lymphomas (NHL). Intraoral lymphomas are relatively rare and often difficult to diagnose in clinical settings. In this case report, we describe a case of primary DLBCL affecting the anterior part of the hard palate of an elderly male patient. DLBCL of anterior part of hard palate is yet to be reported in the English literature, even though DLBCL cases involving the posterior palate have been recorded, thus making the present case to be first of its kind. Emphasis has also been given on the subclassification, differential diagnosis and prognostic antibody factors determining the outcome of DLBCL.
