Linfoma cardiaco primario: Presentación de dos casos en pacientes inmunocompetentes
2002
Background: Primary cardiac lymphomas (PCL) are extremely rare in immunocompetent patients. Their pathogenesis seems obscure and a few studies which have sought Epstein Barr virus (EBV) agree that this is generally not demonstrable. Cases: Two cases of cardiac lymphoma have been described. In both cases, as usually occurs, the histological diagnosis was performed after post-mortem examination. Histological examinations revealed a B large cell lymphoma in both patients. Autopsy material from both cases showed an imflamatory focus distant from the tumoral mass. EBERs and LMP for EBV were negative. Conclusions: PCLs are often fast-growing tumours with a highly unfavorable prognosis. Epstein-Barr virus appears to play no role in the development of this malignant condition.
