title: [Cardiac involvement in non-Hodgkin's lymphoma].
abstract: In a 47-year-old man with non-Hodgkin's lymphoma which had been treated by polychemotherapy and radiation, cardiac involvement was suspected on computed tomography (CT) two years after diagnosis. The ECG demonstrated atrial flutter and a slow ventricular rate. After a further cycle of chemotherapy the patients declined further treatment. Two years later he was admitted urgently because of cardiac failure, atrial fibrillation with a slow ventricular rate, and clear signs of abnormal repolarization. CT of the thorax again provided signs of cardiac involvement with lymphoma. In addition there were extensive tumour infiltrates in the liver and paraaortic lymph-node. Despite intensive medical treatment he died shortly after admission from cardiac failure. At necropsy all four cardiac chambers and the coronary arteries were surrounded completely by tumour tissue. The membranous interventricular septum, the area of the Hiss bundle and the tricuspid and mitral valves had also been infiltrated. Histologically the infiltrates consisted of lymphoid cells of centrocytic type. Increasing tumour cell involvement went together with complete disintegration of myocardial fibres.
