Cardiac lymphomas are rare, and the spectrum of pathologic features is not well defined. We encountered an unusual case of cardiac lymphoma residing within a presumed thrombus. To place such cases in context, we reviewed all cardiac lymphomas presenting to a large US cardiovascular medicine referral center during a 30-year period. A total of 14 cardiac lymphomas were identified, and these included 6 primary cardiac lymphomas (PCLs) and 8 lymphomas secondarily involving cardiac structures. Upon review, 3 of the PCLs were confirmed to be diffuse large B-cell lymphoma, not otherwise specified, involving the myocardium. The other 3 cases of PCL lacked myocardial invasion and showed lymphoma cells embedded in fibrin thrombus. Acute inflammation was not evident. These lymphomas presented in immunocompetent male individuals and involved either a prolapsed myxomatous mitral valve, a pseudomyxoma from the left atrium, or a thrombus arising in a synthetic aortic root graft. All 3 consisted of large atypical lymphocytes expressing a nongerminal center B-cellimmunophenotype. Two cases were positive for Epstein-Barr virus (latency type III), but none demonstrated human herpes virus-8 latent nuclear antigen. No systemic disease was found at presentation or during follow-up. In our experience, fibrin-associated large B-cell lymphoma arising in the heart represents a substantial proportion of PCL. These lymphomas appear to represent an underrecognized variant of diffuse large B-cell lymphoma with favorable outcome. Further study is needed to understand their natural history.
Am old enough to understand the difference between the Bay of Pigs - and roasting a pig at a epicurian feast. Been thru the hippy, yippie and yuppie years - always remaining who I am.
Very much believe in "Sing your own song - weave your own tapestry"
Am young enough to still know the thrill of new discoveries, the beauty of the evening, to celebrate the joy of another tommorow.
Survived these many decades with a severe medical problems. Sorting out the maze of now having two lymphomas and all their nasty little companions, but I continue.
Besides, being a simple iconoclastic eclectic, have been called many things. An incurable romanticist - with a strong touch of reality. Thinker, intellectual (God, how I hate that term) - been told I am a lion with the heart of the poet.
Know how to wage war and conquer my foes - but would rather be known as one who brings hope and life. To bring hope into anothers life is the ultimate of joys.
Life should be about bringing hope, peace, vision... a sense of purpose beyond yourself.
