[Long-term complete remission of HIV-negative primary testicular plasmablastic lymphoma treated with bortezomib in combination with EPOCH].

Plasmablastic lymphoma (PBL) is a rare variant of diffuse large B-cell lymphoma that is frequently associated with HIV infection or other immunodeficiencies. We present a case of HIV-negative primary testicular PBL with long-term complete remission (CR) and successful treatment with bortezomib in combination with EPOCH (V-EPOCH). Because of rapidly increasing right testicular swelling, an 86-year-old man without immunodeficiencies was admitted to our hospital.
