RESUMEN
El linfoma cardíaco primario (LCP) es un tumor extraordinariamente infrecuente en pacientes inmunocompetentes, de diagnóstico dificil y a menudo tardío, que comporta un pronóstico muy grave y escasas posibilidades terapeúticas.Presentamos un caso de linfoma no Hodgkin cardíaco primario en un paciente de 46 años, inmunocompetente, que debutó con insuficiencia cardíaca y flutter auricular. Se practicaron estudios con ecocardiografía transesofágica (TEE), tomografía computarizada (TC) y resonancia magnética (MR) que detectaron una tumoración intracardíaca localizada a nivel del septo interauricular. El diagnostico se fundamentó en el examen citológico del liquido pleural. Se instauró tratamiento quimioterápico y se sometió al paciente a un autotrasplante de precursores hematopoyéticos. El paciente permanece en remisión 36 meses después del diagnóstico y 29 meses del autotrasplante. Nuestra experiencia indica que un diagnóstico precoz y preciso conjuntamente con un tratamiento antilinfomatoso apropiado y agresivo puede ayudarnos a obtener una supervivencia prolongada en pacientes con LCP (AU)
The primary cardiac lymphoma (PCL) is an extremely infrequent tumor suffered by immunocompetents patients with a difficult diagnosis and slow progress leading to a serious prognosis and few therapeutically possibilities. It's a primary-cardiac non-Hodgkin's lymphoma (NHL) in a patient of 46-year-old, immunocompetent, who started with a congestive heart failure and atrial flutter. Some examinations were carried out such as a transesophageal echocardiography (TEE), a computed tomography (TC) and a magnetic resonance imaging (MRI) and an intracardiac tumor placed in the interauricular septum was detected. The diagnosis was based on a pleural fluid cytological examination. It was decided to follow a chemotherapy treatment and the autologous peripheral blood stem cells transplantation was carried out. The patient remains in full remission thirty-six months after diagnosis and twenty-nine months after the autotransplant. Our clinical experience indicated that an early and accurate diagnosis combined with the appropriate and aggressive antilymphoma therapy can thus help in obtaining a long survival in patients with PCL (AU)
