The role of autologous bone marrow transplantation in primary effusion lymphoma: a case report and literature review

Abstract

Primary effusion lymphoma (PEL) is an aggressive and rare type of diffuse large B-cell lymphoma (DLBL) that commonly presents itself as pleural, pericardial or peritoneal effusion without lymph node or extranodal involvement in immunosuppressed patients, such as HIV-positive or transplanted receptors. On rare occasions, it may be found in solid sites without effusion, in an immunophenotypically and morphologically similar neoplasm well-known as extracavitary PEL (EC-PEL). Both PEL and EC-PEL are associated with extremely poor prognosis. Due to the rarity of these entities, ther e are no gold standard treatments . Here we discuss the role of autologous bone marrow transplant (auto-BMT) in the treatment of these patients as well as report the case of a young HIV-positive male diagnosed with both PEL and EC-PEL, who underwent a salvage therapy with auto-BMT and achieved complete and sustained remission eight years after the diagnosis.
