Primary mediastinal large B-cell lymphoma in an HIV-infected patient

HIV-related non-Hodgkin lymphoma is well documented in the literature. We report a case of an HIV-infected patient who presents with primary mediastinal large B-cell lymphoma. On review of the literature, this appears to be the first documented case of this subtype of large B-cell non-Hodgkin lymphoma seen in an HIV-infected patient. Our patient received CHOP (cyclophosphamide, hydroxydaunomycin, Oncovin, prednisone) chemotherapy with granulocyte colony-stimulating factor support but unfortunately died a few days later.
