Introduction
Primary cardiac lymphoma (PCL) is rare, with a frequency of 1.0% to 1.6% among cardiac malignant tumors [1]. Treatment options include surgery, chemotherapy, radiation therapy, or combined techniques; the optimal strategy remains unclear. We herein report successful resection and reconstruction using a bovine pericardial patch for a huge cardiac malignant lymphoma occupying the right heart. The patient gave written informed consent for surgery and the use of his data for diagnostic and research purposes prior to the surgery. The case report was approved by the Institutional Review Board.
