This is the heart of a 38-year-old, previously
healthy, asymptomatic woman who suddenly collapsed and died while watchingTV.
Autopsy of this patient disclosed extensive
metastases not only to her heart, but also to her liver and intestines (imagebelow). The site of the primary melanoma was never established. Death
undoubtedly resulted from an arrhythmia.
Cardiac metastases ordinarily are clinically
silent. But when signs or symptoms do occur, pericardial effusion (with orwithout tamponade) and dysrhythmias are the most common presentations. Cardiac
failure, however, as well as superior vena caval syndrome and othermanifestations related to intracavitary metastases, may develop as well.
From a percentage standpoint, melanoma is the most
frequent neoplasm metastasizing to the heart (about 65%). Furthermore, theabsolute amount of tumor deposited in the heart in cases of melanoma is far
greater than that of any other cancer. In one reported case, for example, themelanoma-infiltrated heart weighed 2450 gm! Findings of this sort have given
rise to the term “charcoal heart.”
