Malignant non-Hodgkin's lymphoma presenting with arrhythmias and conduction detects: Two case reports

Primary cardiac lymphoma is very rare. Secondary localisations are more com mon, observed in 15 to 30% of autopsy series. Clinical symptoms of cardiac involvement are rare, explaining the usual post-mortem diagnosis. The prese ntation of cardiac involvement by arrhythmias and conduction defects is ver y uncommon. The authors report two cases, the first of a 35 year old man in whom primar y cardiac lymphoma presented with ventricular tachycardia complicated secon darily by complete atrioventricular block (AVB) with pseudo-inferior wall i nfarction. The second case was a 37 year old man with a cutaneous T cell ly mphoma in whom complete AVE was the first sign of a secondary cardiac local isation of his disease. The finding of cardiac lymphoma should lead to aggr essive chemotherapy as soon as possible.
