Primary cardiac lymphoma in both atria: A case report.

Primary cardiac lymphoma (PCL) is a very rare kind of primary heart tumor, belonging to non-Hodgkin's lymphoma whose major pathological type is diffuse large B-cell lymphoma. The common symptoms include heart failure, pericardial effusion, and malignant arrhythmias. Early diagnosis and treatment of PCL are of great importance due to its merely 7-month median survival period. Here, we report a 48-year-old male patient in whom both atria were involved and had to undergo palliative surgery because of severe clinical symptoms.
