Résumé
A 61-year-old man, consulted the clinic for dyspnea and cough worsening for 15 days. His past medical history was limited to a cutaneous melanoma 15 years previously, treated by surgery. He was thought to be cured, and was relapse free for the subsequent five years. Echocardiography revealed a large intracardiac mass occupying at least three quarters of the right ventricle, extending to the outflow tract. Echocardiography, MRI findings and anatomopathological examination are presented. Melanoma metastatasis is discussed, with particular attention to cardiac localizations.
