Primary cardiac plasmablastic lymphoma: report of a case and literature review / 中华血液学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To report a case of primary cardiac plasmablastic lymphoma to investigate its clinical feature, diagnosis, therapy and prognosis.</p><p><b>METHODS</b>A case of primary cardiac plasmablastic lymphoma was studied. The imaging examination, conventional histopathological and immunohistochemical staining of this case were detected. The clinical feature, pathogenesis, diagnosis, therapy and prognosis of primary cardiac plasmablastic lymphoma were further investigated through literatures review.</p><p><b>RESULTS</b>The tumor was located in the right atrium. Microscopic examination showed diffuse proliferation of large lymphoid cells. The neoplastic cells were positive for CD38 and CD79a. The patient was treated with chemotherapy combined with autologous stem cell transplantation.</p><p><b>CONCLUSION</b>Primary cardiac plasmablastic lymphoma was extremely rare. Its pathogenesis remained to be unclear. With non- specific clinical manifestations, the diagnosis was mainly confirmed by histopathological and immunohistochemical staining method. Without standard treatment, more patients were treated with chemithreapy regimens similar to the treatment used in aggressine lymphoma. Patients usually had a poor prognosis.</p>
