RESUMO
Cardiac papillary fibroelastoma is a rare, benign cardiac tumor. It often arises from the valvular endocardium and is usually solitary. Nonvalvular location is rare and even more rare is the presentation as multiple masses. A 71-year-old female patient was referred for echocardiographic evaluation due to progressive fatigue. The presence of multiple left atrial masses was observed on echocardiographic evaluation. The patient was treated surgically for the prevention of embolic complications, and the histologic diagnosis of multiple nonvalvular papillary fibroelastoma was made. This case highlights the need to consider this unusual location and presentation for this type of tumor.

Primary cardiac lymphoma is defined as non-Hodgkin lymphoma involving the heart and/or pericardium. It is a rare cancer that primarily affects the right heart and in particular the right atrium. By contrast, renal cell carcinoma is a relatively common cancer, which in rare circumstances can metastasize to the heart. It is now known that there is an association between non-Hodgkin lymphoma and renal cell carcinoma, although the underlying mechanisms are not fully understood. The authors present a case of primary cardiac non-Hodgkin lymphoma in a patient with concomitant renal cell carcinoma and explore the possible reasons for this association.
