Reporte de dos casos clínicos de melanoma con metástasis cardíacas: ("dos caras de una misma moneda") / Melanoma with cardiac metastasis: report of two cases

A 39 year old man presented with signs of an ischemic in-farct in the territory of the medial cerebral artery. A large mobile mass was present in the left atrium and a biopsy showed tissue heavily infiltrated with fat and resection was not possible. A small lesion located at the dorsum allowed a histologic confirmation of a melanoma. The patient died 4 months after surgery. The second patient, a 34 year old woman being treated with chemotherapy for an ovarian melanoma was found to have a right atrial mass. After successful resection of the mass a metastasis of the original melanoma was confirmed and the patient remains in good condition at mid term follow up.
