%X Los tumores card赤acos, son entidades raras en la pr芍ctica m谷dica, tienen una incidencia del 0,05%, aproximadamente el 75% es benigno y un 25% maligno. De estos el linfoma es infrecuente representando alrededor del 0,25%. Los linfomas no Hodgkin pueden ser extranodales en el 20% de los casos, as赤 mismo el 80% de los linfomas no Hodgkin son de c谷lulas B difusos, que es la forma m芍s frecuente de presentaci車n en adultos j車venes; corresponden a alto grado de malignidad y crecimiento r芍pido, pueden presentarse con infiltraci車n primaria a diferentes 車rganos, con afectaci車n cardiaca en 20 a 28% de los casos y suelen localizarse en las cavidades derechas. Los s赤ntomas son inespec赤ficos, dependientes de la localizaci車n y extensi車n del tumor y la prueba diagn車stica en estos casos es indudablemente la biopsia ya sea del ganglio linf芍tico o del tejido afectado. Se presenta un caso de linfoma no Hodgkin difuso, de c谷lulas grandes con afectaci車n intra-auricular derecha, en una paciente de 23 a os que debut車 con disnea progresiva. Se realiz車 un ecocardiograma transesof芍gico que detect車 una masa tumoral intra-auricular derecha, por lo que se realiz車 biopsia por cateterismo venoso por v赤a femoral, que permiti車 hacer el diagn車stico histopatol車gico y establecer el tratamiento, con lo cual se encuentra en primera remisi車n completa a un a o del evento Cardiac tumors are rare entities in clinical practice, with an incidence of 0.05%. Approximately 75% are benign and 25% malignant. Among these, Lymphomas are uncommon, representing about 0.25%. The non-Hodgkin lymphomas can occur in extranodal tissues in 20% of the cases and 80% of these non-Hodgkin lymphomas are composed of diffuse B cells. The extranodal presentation is most frequent in young adults, with a high degree of malignancy and rapid growth. It can present with primary infiltration of various organs; cardiac involvement occurs in 20 to 28% of cases, usually located in the right chambers and with nonspecific symptoms, depending on the location and extent of the tumor. The diagnostic test in these cases is undoubtedly the biopsy of the lymph node or the affected tissue. We present the case of non-Hodgkin disease of diffuse large cells, with right intra-atrial involvement in a 23-year-old-female patient, who presented with progressive dyspnea. A transesophageal echocardiography was performed and an intra-atrial tumor mass was detected. A biopsy was performed, by femoral venous catheterization, allowing the establishment of the histopathological diagnosis and treatment. At a one year follow up, the patient shows complete
