Fundamento: El linfoma cardiaco primario (LCP) es muy infrecuente en pacientes sin alteraciones inmunitarias habiéndose descrito unos 50 casos en el mundo hasta 1996. Su patogenia no se conoce y algunos estudios que han investigado la presencia del virus de Epstein Barr en el tumor en general no lo han demostrado. Casos: Se describen los casos de dos pacientes con LCP. En ambos casos el diagnóstico fue realizado post mortem. Ambos pacientes presentaban un linfoma B de células grandes difuso. En los dos casos se ha identificado la presencia de focos inflamatorios a cierta distancia del tumor. No se ha podido demostrar la presencia de VEB en el tumor. Conclusiones: Los LCPs son tumores de rápido crecimiento con un pronóstico muy desfavorable. El virus de Epstein-Barr no parece desempeñar un papel en la etiopatogenia de estos tumores. 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.
