The heart is an uncommon site of metastatic tumor. Explanations for this include the relative avascularity of the endocardium, vigorous kneading action of the myocardium, the rapid blood flow through the heart, and the paucity of lymphatic communications between the heart and surrounding tissues.4 In a review by Karwinski and Svendsen5 of more than 2800 autopsies on patients with malignant tumors, 130 (5%) of the patients had cardiac metastases. In these 130 cases, the most common primary tumors were lung (46%), cutaneous melanoma (10%), and breast (8%). There were no cases of uveal melanoma. Of the patients with cardiac metastases, most had metastatic disease elsewhere.
