[Malignant non-Hodgkin's lymphoma presenting with arrhythmia and conduction defects. Report of 2 cases].
Primary cardiac lymphoma is very rare. Secondary localisations are more common, observed in 15 to 30% of autopsy series. Clinical symptoms of cardiac involvement are rare, explaining the usual post-mortem diagnosis. The presentation of cardiac involvement by arrhythmias and conduction defects is very uncommon. The authors report two cases, the first of a 35 year old man in whom primary cardiac lymphoma presented with ventricular tachycardia complicated secondarily by complete atrioventricular block (AVB) with pseudo-inferior wall infarction. The second case was a 37 year old man with a cutaneous T cell lymphoma in whom complete AVB was the first sign of a secondary cardiac localisation of his disease. The finding of cardiac lymphoma should lead to aggressive chemotherapy as soon as possible.
