[Cardiac metastasis of malignant melanoma].
Cardiac metastatic malignant melanoma. Secondary tumors frequently involve the heart, but the main data about incidence, rate and localization into the specialized myocardium are poor and fragmentary. Post-mortem examination of the conduction system of arrhythmic hearts was studied in two cases of malignant melanoma. In the first case signed by AV block and fibrillation, metastases involved the myocardium over atrioventricular (AV) node and the left and right bundle branch (L and RBB). The second case had not arrhythmias in the clinical picture, but a large metastatic mass involved the junctions between sinoatrial (SA) node and myocardium of the crista terminalis, the junctions between atrium and AV node and the left branch.
