Lymphoma with clinical presentation of a primary pericardial tumor.

Primary malignant cardiac tumors, particularly lymphoma, are rare entities. Cardiac involvement or metastization of the heart from neoplasia located elsewhere are more frequently found. We present the case of a 79-year-old patient admitted with heart failure symptoms with a 3-week evolution. Evaluation led to the identification of a cardiac tumor with unusual clinical presentation and with a rapid and fatal evolution. Pathologic analysis identified a B-cell non-Hodgkin lymphoma.
