Abstract

Plasmablastic lymphoma is an HIV-associated non-Hodgkin's lymphoma that primarily affects the oral cavity and jaws. The purpose of this report is to describe the first case of plasmablastic lymphoma occurring in an HIV-negative, nonimmunocompromised individual, and to review the histopathologic and immunohistochemical phenotype of this lymphoma. Histopathologically, our case exhibited a dense, diffuse lymphocytic infiltrate of noncohesive large lymphocytes with plasmacytoid features. Immunohistochemical analysis revealed positivity for the B-cell marker CD79a, VS38c, Epstein-Barr virus latent membrane protein (LMP), immunoglobulin G (IgG), and lambda light chain restriction. Neoplastic cells were negative for leukocyte common antigen, CD20, CD3, CD10, CD138, Bcl-2, Bcl-6, desmin, actin, EMA, S-100, HMB45, Alk-1, HHV8, IgA, IgM, and cytokeratin. The features of this rare disease are summarized based on a comprehensive review of the epidemiologic, clinical and immunohistochemical findings of previously reported cases.
