title: Two cases of primary cardiac lymphoma presenting with pericardial effusion and cardiac tamponade.
abstract: The heart as the primary site of lesion in malignant lymphoma is extremely rare. We experienced 2 cases of malignant lymphoma whose initial presentation was massive pericardial effusion with cardiac tamponade. The first case was a 75-year-old man who had shortness of breath for 1 week. Chest X-ray showed cardiomegaly (CTR 65%), and his condition was diagnosed as congestive heart failure at first and thereafter echocardiogram revealed pericardial effusion. The second case was a 76-year-old man who complained of exertional dyspnea which worsened over 2 weeks. His condition was diagnosed as congestive heart failure at first and echocardiogram revealed pericardial effusion. Pericardial drainage tapped bloody fluid and cytological examination revealed malignant lymphoma. After treatment, the first case lived for eleven months with no recurrence of pericardial effusion. The second case has lived for 4 years. We present these 2 cases can be defined as primary cardiac lymphoma according to McALLISTER and FENOGLIO, i.e., a lymphoma that involves only the heart and pericardium. More cases of primary cardiac lymphoma will be found in the future because of the ease with which the echocardiogram can detect pericardial effusion.
