Blood, 15 June 2003, Vol. 101, No. 12, pp. 4708-4710 A unique atrial primary cardiac lymphoma mimicking myxoma presenting with embolic stroke: a case reportFrom the Department of Pathology, Division of Cardiology, and Division of Cardiothoracic Surgery, Naval Medical Center, San Diego; and the Department of Pathology, Scripps Clinic, La Jolla, CA.
An immunocompetent 29-year-old male presented with an embolic stroke from an unusual primary cardiac lymphoma. The cardiac lesion consisted of a polypoid, left atrial, mural fibrin thrombus with anaplastic tumor cells lining the surface of the clot. Histologic, immunophenotypic, and molecular characterizations were consistent with a diagnosis of CD30+ large B-cell lymphoma with anaplastic cytology. While tumor emboli from invasive primary cardiac lymphomas have been reported, this noninvasive fibrin thrombusassociated lymphoma appears to be unique and previously unreported.
