Right atrial mass in the context of recurrent non-Hodgkin's lymphoma: atrial myxoma presenting with atrial flutter

Abstract

A case is described of a 57-year-old man with a background of low-grade bronchus-associated lymphoid tissue (BALT) non-Hodgkin's lymphoma presenting with dyspnoea and palpitations. Diagnostic work-up revealed paroxysmal atrial flutter and the presence of a mass in the right lower lobe at bronchoscopy, with histology confirming recurrent BALTOMA. Transthoracic echocardiography (TTE) revealed a mass in the right atrium. Transoesophageal echocardiography (TOE) confirmed the presence of a fleshy, mobile pedunculated right atrial mass adherent to the interatrial septum, with features more in keeping with an atrial myxoma rather than intracardiac lymphoma. He proceeded to cardiotomy and excision of the mass with histology confirming an atrial myxoma. The clinical and echocardiographic features of atrial myxomas and intracardiac lymphomas are briefly discussed.

Epicardial pacemaker implantation for sick sinus syndrome in a patient with supra vena cava obstructed by a primary cardiac lymphoma

“…The most common primary malignant tumors are sarcomas and lymphomas. PCL is rare (1%), but secondary involvement of the heart is not uncommon in lymphoma (20%) [4]. PCL has been linked to immunosuppression, including that seen in human immunodeficiency virus infection, but is extremely rare in immunocompetent subjects where it is most frequently associated with rheumatoid arthritis [4].…”

PCL has been linked to immunosuppression, including that seen in human immunodeficiency virus infection, but is extremely rare in immunocompetent subjects where it is most frequently associated with rheumatoid arthritis [4]. Previously, a close relationship between Epstein-Barr virus infection and malignant lymphomas was discovered in immunodeficient patients [5].…”
