Linfoma primário do coração em doente com neoplasia renal síncrona

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.
