Why the study?
The study was motivated by the rarity and unusual diagnostic and therapeutic features of invasive tumors presenting with transvenous and intracardiac extensions.
This report highlights the rare clinical presentation of type A thymoma and myxoma with transvenous and intracardiac extensions.
May prompt consideration of rare tumor extensions in cardiac mass differentials; extends limited case literature on transvenous involvement.
We report two cases of rare invasive tumors presenting with transvenous and intracardiac extensions. In one instance, an unusual invasive thymoma type A penetrated into the heart chamber; the other case was an extension of a myxoma into the right atrium that was associated with superior vena cava syndrome. Our interest was stimulated by the rarity of these clinicopathological observations and the unusual clinical features of diagnostic and therapeutic methods presented by these cases.
